Answer to:
What role does "void" play in a programming language? In Java, a function which returns void returns no value, and the caller must not assign the value of function returning a void to anything. In C/C++, void has additional meanings, in particular when using (void *), which really means a pointer to an untyped object. This pointer of this type must be cast into another type for it to be dereferenced. And there are some other more esoteric uses...

Whats the big deal about global warming? it doesnt matter to much to me, i love the warmness. Well, it has the potential to displace millions of people due to rising sea levels, kill off millions of species (because many of them cannot evolve fast enough to react to the changing climate) and upset the food chain and sources of fresh water so much that it makes it hard for even humans, whom are highly adaptable, to survive.

To improve your sense of balance (which relies more on sight than you might have guessed), and to improve your sense of awareness using senses other than sight, which is mostly limited to touch (for close-range fighting), sound, and to a lesser degree your sense of air movement and vibration. That said, a lot of martial arts instructors will tell you that you can sense your opponent even...

Do you think that LHC scientists will find a particle that carries the force of gravity? No, they aren't looking for the graviton (or other gravity related particles). Most physicists believe that gravitons exist, but they are nearly impossible to detect because they are incredibly weak. Gravity waves should be much easier to detect, but even with the most sophisticated instruments (look up LIGO in Google, for example), even they haven't been detected. That said, the LHC may...

Why would "Information"not be able to travel faster than light? http://www.msnbc.msn.com/id/34938302/ I understand Mass but not information. Information needs some sort of physical "carrier" to travel upon. The fastest carrier known is light. No experiment, to my knowledge, has ever shown that it's possible to transfer information faster than this rate. Many physicists have proposed mechanisms using entangled photons to cause information to travel faster than light, but so far these have all been shown not to work (in theory)...

what happens when we sit in dark? does time stops? I'm not sure where you get the idea that time is created when light hits an atom. Time is thought of as a dimension, similar to space. In fact, in Special (and General) Relativity, space and time are bundled together into something called spacetime. Time exists, even in the absence of light or atoms.

Answer to:
how time travels for a person travellin at or greater than speed of light? I think if you just follow the mathematics of it relativity, you will see that time would become a complex number having an imaginary component to it.

Answer to:
for a function to return more than one value, it must be passed the address of the variable to be returned.. why is this so? In a broad sense, functions have only a single return type, but that type can be a class or struct (if we're talking C/C++), record, etc., and so can contain multiple values. So even though the language may not permit directly returning more than one value, you can in fact return more than one value by using types that contain more than one element.

Answer to:
60 joules of work are required to lift the 10 newton object 5.0 meters. The amount of work done in overcoming friction as the weight is lifted is how many joules? Well, force times distance give the number of Joules. So 10 newtons times 5.0 meters is 50 Joules. If it actually took 60 Joules to lift the mass, there was (60 - 50) = 10 Joules left over for something else, so you can assume, I suppose, that all of those Joules were spent in overcoming the friction.

IrDA stands for Infrared Data Association, and uses a Infrared transceiver in each device to communicate. However, I believe it's mostly been replaced by...

How to add an undo/redo function to my java application? You need to be able to keep track of each change as a delta of some sort, and be able to unwind each of the changes that were made. Once you have a system for keeping track of deltas, you can place these deltas in a linked list, and then traverse the list, applying (or unapplying) the deltas, as the undo and redo actions activated. As soon as a new change is made, you can discard the rest of...

What two reasons can you think of to explain the need to use different radioisotopes to date different rocks and fossils? what types of isotopes would you use to date a very old and a very young rock? Different isotopes have different half-lives, so depending how old the rock is, you may want to use a different isotope ratio to get a more accurate age estimate. The second reason that occurs to me is that in some samples, a particular isotope may exist in very tiny quantities or not at all, which would make it very difficult to impossible to use for dating. So you might choose another...

Since one of our universal laws is gravity..in the beginning could it have been the creator of matter itself if it warps and creates friction particles? Gravity might be one of the forces that becomes unified with the others (electromagnetism, the weak force, and the strong force) at very high energy levels. No one knows for sure that all of the forces become unified at high energy levels, but many if not most physicists suspect this to be the case, due to several lines of tantalizing evidence, that at extremely high energy levels, there is...

Perhaps for the same reasons we don't follow many of the rules in the Bible anymore. For example, there is a rule in Leviticus that states that if a woman is raped in the countryside, only the man is stoned to death, but if she is raped inside a town, both the woman and the man are stoned to death.

If a fast travelling astronaut travels slightly into the future due to time dilation, does it mean he travels back in time when he is reunited with his earth bound friends? No, the moving forward in time is a permanent thing. Most physicists think that there is no mechanism available for traveling backward in time, and that it may be impossible in principle. But that doesn't stop science fiction writers from thinking about the consequences of backward time travel, and physicists from exploring all of the possibilities of achieving it.

Time travel? Given that matter/mass can't exceed the speed of light, why can't we send INFORMATION into the future or past, since information has no mass. Then we can use this information almost as well as we could use a messenger who time-traveled! Matter/mass cannot *reach* the speed of light, let alone pass it. Massless particles travel at the speed of light, but cannot exceed it. Information needs some sort of carrier upon which to travel, whether it's massive or massless particles, so it does not get to break the speed limit rules.

No, there is no such proof, because the number of possible musical notes is limited only by human perception.

It is a pointer which the caller cannot dereference to point to anything usable by him, but is a pointer to memory nonetheless....

How can you have a 1 hp single phase120 vac motor and a 1hp 220 vac motor with the same current output...Something must be different. If 1hp is equal to 750 watts. Doing the math one is 6.25 amps & the other 3.4 amps....220 seem more efficient? I don't know what you mean by "current output". Motors use current... they don't put out current. But in answer to your question, the current should be different, whether it's a single-phase or 3-phase 220VAC motor. If it's 3-phase, the current in each winding should be 1/3rd of total. Just to compare apples to apples, compare a single-phase 120VAC motor to...

750 Watts, is 750 Joules/second. So time is an intrinsic part of Watts. But how do you measure the wattage output of a 6 amp motor for 10 hours The other answers are right, but are not concrete about the example you gave: Assuming the motor runs at 120V, it's 120V x 6A = 720W. You don't need to consider time there... it's 720W of output for the whole 10 hours. Now, if you want to consider energy over that 10 hour period, just multiply the 720W times the time = 720W x 10h = 7200Watt-hours. You can use the...

However, you won't need speakers anywhere near that power, if this is for your home. Get a couple of decent 50-100W speakers and you'll be more than fine.

Radio waves are able to diffract readily around building, as anybody with a portable radio receiver can verify. However, light waves, which are also electromagnetic waves, undergo no discernible diffraction around buildings. Why not? diffraction is a function of wavelength.

Do you think the discovery of "Ardie" (ardipithecus ramidus) is dead solid proof if evolution? enough to make creationist' stop talking? No, because you have to remember that Creationists don't start with evidence, they start with "the Answer", and then work backward to find evidence which supports their answer, and to find ways of dismissing or re-interpreting evidence that is in contradiction of their answer.

In addition to earth, air, water and fire, are there any other 'elements?' (no, I did not see the movie 5th element) To give a more "sciency" answer, the elements you listed are not considered elements by chemists. Instead there are about 100 elements, hydrogen, helium, on up to plutonium and other shorter-lived "transuranic" elements.

Would the Sun's brightness change if the temperature became 11,600 K and if so how much Well, that's about a doubling of the Sun's surface temperature. Assuming luminosity (brightness) is directly proportional to the amount of power put out by the Sun, since the power varies as a function of the temperature to the fourth power, doubling the temperature should cause it to put out 2^4 = 16 times as much power. However, the light would move up in the spectrum, and more...

Calculate the force acting on the hydrogen atom. If you're going to be so lazy as to just copy&paste your homework answer in without even giving what confuses you about this question, you should at least make sure the question is pasted in correctly.

If they are just connected in series with some sort of current limiting resistor, you will likely fry the LED's because LED's act as a rectifier and only one half of the AC wave will go through the...

Every time my mother forgets to turn off the electric stove, so, i want to design an instrument which detects the overflow of milk from electric stove, whenever milk overflows a buzzer sound is used. such that i can save some money. Using low price method A couple of things come to mind: 1) When the milk overflows, it will contact the heating element, and cool it abruptly, lowering its resistance for a short time. So if you had a circuit that monitored the current flowing through the element and watch for dramatic increases in current, you could trip a relay that would shut off power to the range (or engage a buzzer) 2) Another technique,...

Normally, space cannot be made into a grid of point consistently with relativity. But suppose that velocities are quantized -- so they are all multiples of a v0 (or v^2 are all multiples of a v0^2)?

Why there is no need of CSMA /CD on a full duplex ethernet LAN (2009-09-11) If you have a dedicated line (on a CAT-5 cable, for example) for transmitting data to a switch or to another host, there is no possibility for collision, so there is no need for sensing a carrier or doing collision detection. In these cases, you can understand how there is no "multiple access" either, since the transmit lines (and receive lines) are dedicated.

A car takes as much energy to deccelerate(slightly less) as it does to to accelerate and yet we waste brake pads... with the proper pedal actuated gearing, your alternator can bring you to a stop while generating e for the mc rather than needing new pads!

What is the difference between lcd tv and led tv.? The current crop of so-called LED TVs are really LCD TV's which use white-light LEDs for a backlight instead of cold cathode fluorescent lamps. The LEDs have a longer lifespan, use less power, and can be controlled individually to give sections of the screen much greater contrast. On the other hand, Samsung and other manufacturers have been trying to get away with a lie, really....

My lovely 2-year-old Sony VAIO PC/TV lost a blade on its cooling fan, which then stopped. The mother board got fried, & it cost me $480 to get it replaced. It seems like this is clearly a manufacturing defect. Do you think Sony would pay for this? $480?! The repair guys saw you coming! You could get 4 nice new motherboards for that much money. I doubt Sony will reimburse you, unless you had the repair done at a Sony authorized service center and it was still under warranty. That said, it couldn't hurt to write a nice letter explaining what happened, including a photograph of the broken fan if you still have it.

Answer to:
Is fork lightning affected by wind? Like does it move when wind is blowing it? Yes, once an ionized channel is formed in the air, if the air is moving, and the lightning strikes through that channel again, it will follow the same (or very similar) channel which has now been moving with the "sea of air". So the lightning bolt make look similar, but will have moved downwind.

Answer to:
How does a laser actually cool the bose-einstein condensate? is it a matter of synchronising all the states of the atoms? The lasers are tuned so that photons are absorbed by the atoms only when they are moving toward the laser at a velocity above some minimum. This velocity creates a slight blue shift of the laser light, and those atoms which absorb the photons are slowed down. As they slow down below the minimum, they stop absorbing photons because the doppler shift takes the frequency out of the range where...

WHY IS THE SKY RED during fires? Because the shorter wavelength (green, blue, etc.) light rays are more scattered and/or absorbed by smoke particles in the air than the longer wavelength (reds) rays.

How would a machine that converts a person into energy and then reconstructs them work, how would it convert the person into energy and how would it reconstruct them? They stand on the transporter pad, another actor slides the prop switches, and voila! through the miracle of video editing and special effects - decomposition. On the other end, you just do the reverse. Just kidding, of course. I don't think there's a valid theory as to how such a thing could actually work in practice. It's just sciencey fiction. Emphasis on the fiction.

Answer to:
If time slows more and more as we approach the speed of light then wouldn't the "faster than light" expansion of the universe make time stop? No, because of the fact that space is expanding, objects aren't actually moving through space at anywhere near the speed of light. No laws are violated.

If the person was moving at the speed of light (c), the doppler shift is infinite.

Answer to:
What are some disadvantages of using solar power as a resource? The places with the most reliable sunlight are not necessarily near the places that need power (though in some places, like Las Vegas, they are). So this can require long and expensive transmission lines to get the power to where it's needed. Wind energy has the same issue as does geothermal, tidal, and wave.

Answer to:
With common methods of electricity generation less than 30% efficient, is the rush to the electric car really the answer to environmental problems? The rush has to do with lessening our dependence on burning CO2 emitting fuels (specifically, those that aren't carbon-neutral). Nuclear power, Solar, and geothermal, tidal, and others are ways of generating energy without emitting CO2. Theoretically we could use these sources to charge our electric cars. However, I think at least 40% of our electricity comes from coal and natural...

What is the mechanism by which carbon-dioxide is able to trap heat in the atmosphere? CO2 has resonant modes in the infrared light range, which causes it to absorb infrared photons and store them temporarily as a vibration.

You can see some nice animations of these vibrations at this web site: http://science.widener.edu/svb/ftir/intro_ir.html One...

My brother says that it's possible to live forever if we learn how to lengthen the telomere regions of our genes since it is used in cell division. Is he crazy? He's not crazy, but telomeres are not the only thing limiting human longevity. And shortening telomeres provide some protection against cancer (though this has been recently found not to be as strong as an effect as was originally thought). Inhibiting telomeres from being shortened during cell division might make your life somewhat longer and healthier, but the jury's still out.

The other night the moon was really low on the horizon and it was orange. very orange, but it faded through out the night. What caused the moon to be orange?

When the Moon is lower on the horizon, you're looking through more haze than when it's closer to overhead. If you were out in the desert, a long way from anywhere, the color would not be as orange as it is in the city.

Most of Einstein's theories have been tested to high degrees of accuracy, and so far haven't been disproven, so it's going to take a theory that makes the same predictions as Einstein's (quantitatively),...

Answer to:
How many ants would it take to lift me? I am a 5ft 9" (nearly 6ft) tall 18 yr old girl with size 13 feet. How many would be squashed before lifting me? According to one source I found, an average ant weighs about 0.0000088 lbs. Supposedly ants can lift 20-50 times their own weight. So let's assume you have some really beefy ants that can all lift 50 times their weight. Let's assume you weigh 130 lbs. Take 130 and divide by (ant's weight times 50). 130 / (0.0000088 * 50) = 295,454 ants.

If you lifted a car battery over your head and attached it to a car alternator and a pully system that spun the alternator for hours as it slowly fell to the ground... would it generate enough electricity to fully charge itself? Depends on how "over your head". There is a formula for the amount of energy in a suspended mass. So it would be a matter of calculating how high you'd have to lift it, accounting for the loss of energy in the pulleys, the alternator, and the process of charging the battery. I wouldn't be surprised if it would have to be at least 1000 feet up to fully charge.

How many processes per second can various operating systems support on a given hardware system? Most OS's will time share a single processor among many programs that are competing for its use. If all of these processes are CPU-bound, most OS's will switch between them at the rate of 100 times per second. So for CPU-bound processes, the most you could handle is 100 in a second. However, if a process does not use up all of its time slice before relinquishing the processor,...

Does praying have any effect on... well anything? is praying to one god even a good idea? wouldn't you think there would be a better chance of "effective" praying if you prayed to every god you can think of? This is an argument similar to the famous "Pascal's Wager" wherein Pascal makes a bet to believe in god (or pray to a god) because if god exists, he'll be ok, but if he doesn't exist, the praying won't hurt. However, Pascal didn't figure on what happens if you pray to one god, but he isn't the real god, and the real god punishes you. In that case you...

Our solar system is thought to be a third-generation star system which has only existed for about 1/3 of the Universe's 14 billion year lifetime. In the early Universe,...

If you had something that spins @ 500 rpm, can you make it spin faster by putting a heavy flywheel on it?. No. Flywheels are used to store kinetic energy, not speed up the spinning. If you attached a flywheel to the thing that spins at 500rpm, the flywheel will actually slow it down at first. The speed should slowly build back up to 500rpm, assuming the bearings and the machine driving it can handle the additional load. Once it hits 500rpm, it will go no faster.

If there exists a charged particle, it sets up an electric field. when it starts moving it creates a magnetic field, but has the electric field ceased to exist? and does this change come about instantaneously from a change in velocity? Q1) No, the two fields exist simultaneously. Q2) Yes. This is described by Maxwell's equations. Keep in mind that motion is relative too. If the charged particle is at rest in your inertial reference frame, there is no magnetic field, but in another person's reference frame which is moving at a non-zero velocity relative to yours, he will detect a magnetic field from that same...

A lake has bass, trout, perch, and pike. Each fish comes in four size categories, small, medium, large and extra large. There is an equal probability of catching each type or size of fish. What is probability of catching a trout OR an extra large fish? You might be tempted to say 1/4 + 1/4, however, there is overlap between the two - a large trout is in both categories. In all, there are 16 possibilities, 7 distinct possibilities of which would be either large or a trout (or in one case, both). So the answer is 7/16.

My friend says two lines traveling to make a point can never touch or intersect because there will always be space between them. What do you think of his hypothesis? If they are "traveling to make a point" you are saying by definition that they intersect. In that case, no. However, if the two lines are parallel, they will never intersect, as long as the space they are traveling through is perfectly Euclidean. If the space is not Euclidean (for example, a sphere), lines that are parallel at one point can intersect at another.

In a photon's reference frame, time does not exist; in their frame they are born and die in the same instant, therefore nothing can be moving relative to them, because that requires time to be non-zero.

Albert Einstein theory of relativity could be wrong: do you agree? Some parts of relativity still haven't been confirmed to be "real", but most parts have. One example of the unconfirmed part is that of contraction. Special Relativity predicts that as objects approach the speed of light relative to you (or any reference object), their length becomes foreshortened. That is, they contract. As they get closer and closer to the speed of light,...

Answer to:
A trillion in the U.S is how many in the U.K? One way to remember the British system is to take the prefix's value (trillion = tri = 3) and multiply it by 6, and that's the number of zeros past the 1. 1 trillion = 1 with 3 * 6 zeros = 1x10^18. Unfortunately, the rule breaks down for million, since the prefix is "mi" = ?? Well, just have to remember that mi = 1, I suppose.

If two objects are moving in the same direction how can we find their velocity? You can only find their velocity relative to one another, or to other objects. There is no absolute velocity relative to the Universe, if that's what you are asking (indirectly).

As the relativistic mass of a particle increases as its velocity approaches the speed of light, does its gravitational pull also increase? Yes. Also, gravitation is not just a function of mass, but also of energy, so even if the energy is massless (a photon, say), it still warps space. I recall reading about a theoretical device that could create a gravitomagnetic field by confining an extremely powerful light beam to a helical path.

Does the RCA model 27V510T manufactured in 2005 have digital tuners? Found the manual on www.retrevo.com, and they don't mention anything about a digital tuner, so I suspect it doesn't have one. The manual is a bit thin on specifications, though.

Answer to:
Has anyone of you--who has read Bigbangist's conjecture--ever wondered how anything of significance could come about without a purpose and plan, if we indeed are the result of a [mindless] "accident"? You've set up another straw man argument again without addressing what I said in your last question about the Universe coming into existence through chance. So you've demonstrated that you can ask a question, but you have not demonstrated that you can read the answers or think rationally about it. Again I will say that the Big Bang theory doesn't propose any theories about...

Please some one tell me can we watch tv in laptop if yes should we have to install any extra interface card or it is possible to watch tv by plugging cable tv cord Please tell me ...... If you are trying to watch TV off of an antenna or cable, you will need a tuner of some sort. There are devices that cost about $100 which plug into your USB port and the antenna plugs into it. They will allow you to watch TV and use your computer like a DVR. However, I have to say that my experience with these sort of devices is less than great. They don't get very good reception...

Answer to:
How can i work the volume on my goldstar dvd/vhs player? it has no volume button on it and the sound is too low. it also has no remote so i bought a rca universal remote. it works everything except the volume. what do i do? DVD players and VCRs almost never have their own volume controls. You need to use the volume control on the TV. If you can't get it to go up high enough, there's either something wrong with the audio cables that are connecting the player to the TV, the player has a bad audio circuit, or the TV does. Start with the volume control on the TV and go from there.

The other day I was testing for an EOL resistor in a circuit and with the + lead on the red wire and the - lead on the black wire I could only see 23.5k You'd need to describe the circuit better than that. Can you post a schematic and show us where you are measuring? In general, though, you cannot measure the value of a resistor accurately while it's still in the circuit, using just an Ohm meter. You'd need to disconnect at least one of the two legs.

It has a strong natural tendency to stop occurring when things malfunction. With fission, uncontrolled reactions can occur, and if all of the reactor's failure recovery mechanisms fail, you can end up with a melt-down. However, with newer reactor designs, this is incredibly...

The problem would be keeping the antenna aimed correctly while on the boat, I think.

Any idea how I can get the 45 and above channels to remain? Yes, it sounds very much like the cable line to your house has a lot of loss at the higher frequencies. This could be due to an old corroded cable, damaged, being water-logged, bad connections somewhere, etc. Best thing to do is call the cable company out and have them check it out. Usually they can isolate the problem within an hour or so and have a good signal again.

Why did Einstein use the eclipse test to prove that space was curved instead of observing the radiating circle of light around a full moon?

Neither of which are related to the curving of light due to gravitational fields.

If i were in a vessle and time slows down when travelling at lightspeeds, would i not measure a light year differently to someone on earth. hence giving us different measurements of the light year Yes, you definitely would measure a lightyear as being a different length. If you were traveling at very nearly c towards a star that's say 4 LY from Earth, starting from Earth, the distance would be compressed, and it would only seem to take a few minutes to travel there on the ship, and therefore much shorter than 4 LY. More like a few light-minutes (depending on how close to c you...

Answer to:
I need to check if my pseudocode is correct. I can I do that? You can try some examples of input and the expected output, and just step through your pseudo code a line at a time, and figure out if it's doing the right thing at every step... and if it gives the correct result. If not, you know either you have not followed the pseudo-code correctly, or the pseudo-code you've created is incorrect. Usually, when you see where it starts to go...

Answer to:
What imparts spin to matter which is coalescing in intersellar space? Matter (gas, dust, etc.) is generally moving before it becomes influenced by a gravitational field. Once it does begin travel toward the body creating the field, its direction won't be pointed directly at the object, but rather at an angle. The path it follows toward the object then becomes of curve, rather than a straight line. Over time, as other dust and gas accumulates, it...

I have a 50H72 Toshiba TV. I am repairing the convergance issue and found a bad resister. Radio shack does not have. I need the resister in location R7726 on the board under the convergance pieces. Bands are blk/wht/brn/gold. It is larger than1 watt. You could try digikey.com That's a 90 Ohm resistor with 5% tolerance. http://www.dannyg.com/examples/res2/resistor.htm

Answer to:
I have tried to hook up the converter box but I can't get the on screen directions to appear. It is a very old JVC television. I have tried two different antennas Help Even without an antenna, you should get some sort of on-screen menu when you have it connected properly. The cable from the converter should go to the VHF antenna input on the TV, and the TV should be tuned to channel 3 or 4 (depending on the converter... check the instructions). Do you have the TV tuned to the correct channel?

Answer to:
Why does oil change color when light reflects off of it? Iridescence is the technical term for this effect. Colors whose wavelength divides evenly into 2 times the thickness of the oil film are reinforced, while colors whose half-wavelength divides an odd number of times into the 2 times the thickness are canceled out. Colors that are in between those two are somewhat reinforced or somewhat canceled, depending on which they are closer to. This...

I met a person on the internet about a year ago. We've been talking all year and I feel like I know her well. I've talked to her on the phone and we txt a lot. I have small trust issues. Do I have enough proof that she really is who she claims te be? You can be married to someone for 20 years and not really know them. I think you ought to meet her and see how it goes.

Where can I find a simple introduction to the "visual formatting model" of css2? I'm trying to parse the documentation at w3c but I'm finding it confusing. It hurts my tiny li'l ole brain ☹. Have you tried: http://w3schools.com/css/css_intro.asp ? Other than that, I usually find that books are better than the web, as they have more and deeper explanations.

Answer to:
Does the sun shine on the moon? No. I just want to be the only one that says, "No, it doesn't shine on the Moon. When you see a bright Moon at night, it's because it's made of tritium with a phosphorus coating, like the old wristwatch dials. Or cheese... I'm not really sure. I hear cheese a lot."

Answer to:
I have one TV that I would like to get a digital to analog converter, but it is so old it doesn't have a co-ax connection on it. Will this be a problem? What can I do? It will work fine. You just need to buy a ~$2 item at radio shack (sold other places too). It's a 75 Ohm to 300 Ohm adapter. The technical name is "balun", but if you ask for that at Radio Shack, I guarantee they will look at you blankly. Just ask for a "75 Ohm to 300 Ohm, coax to twinlead adapter". They'll know what that means. If they don't they...

Answer to:
Why do some rocks and crystals form in geometric shapes, like cubes, prisms, etc...? As I understand it, it has to do with the geometric structure of the specific mineral or crystal right down to the atomic level. Crystals have a regular pattern to them, and they are put together a bit like tinker toys. The pattern can be cubic, or pentahedral, etc. I think if you look up crystals and minerals on the web, you can find quite a few diagrams that will help you understand.

Answer to:
I have a DLP TV 56" .i changed the lamp,but sill have the problem of which is a dark ,transperant,line on the left side of the screen ,does anybody knows the solution? It really sounds like you have a flaw in the DLP device, and has nothing to do with the bulb or color wheel. You need to take it in for repair, and if it's not under warranty, be prepared for a pretty high repair cost.

Answer to:
Can CMBR (Cosmic Microwave Background Radiation) be converted and used as a low energy source? e.g. power a keychain light? Yes you could, but you'd need probably thousands of acres of microwave antennas tuned to 3K to get enough power to light a keychain light. So it's a little impractical.

Answer to:
What is artificial radioactivity? It appears to be a synonym of "induced radioactivity". Basically, you start with a stable element, and then add or remove neutrons to destabilize it, which will cause it decay at some point in the future. Lots more detail here: http://en.wikipedia.org/wiki/Induced_radioactivity

Answer to:
Is there something that can be used to speed up a wireless internet connection? I think I had an antennae at one time but I'm not sure. I just switched from cable to one supplied by the apartments. Anything? Test your signal level too. If you are not getting 70% or better signal, you won't be getting the max bandwidth you can. If your signal strength is suffering, you can buy or make a directional WiFi antenna. Google "wifi cantenna" for instructions on how to build one from a coffee can and some parts for about $10. Or you can buy pre-made ones too for around $50.
