Do you think that anyone will ever invent a time machine? If they did wouldn't they have already come back to our time?

it will lead to numerous paradoxes
so it cant be made

Yes, I think it could. But it wouldn't be a physical machine that would allow for the traveling to take place. Time travel would probably be done through some sort of an alteration of consciousness (i.e. remote viewing and such)

No it can't

asking the wrong person here!! =D

Some things just aren't possible in life.

No, Einstein proved that a time machine is impossible

It's not impossible but highly unlikely.

I don't think so. +5

I hope so :)
+5

Time machine may come ture hundreds years later.

We all have one ...


Its called memory.


;))

I'd actually love to see a physicist answer this question. I mean, we already know that there is a correllation between gravity and time-flow, right? If you are circling the earth in a satellite, you are not aging at exactly the same rate as people on earth. Is there no way in which this could theoretically translate into a time travel device, even if it is one-directional (i.e. only into the future)?

No, but it would be very interesting:-)

Time machine its a fairy tales!!

The television guild has already invented a time machine. Because of their strike, I'm having to watch an episode of House from 2006 during prime time tonight.

What if they already have come back? I mean, why would they tell you?

;)

no, i don't. scientists recently did a study and found time travel to be impossible. what a cool idea though!

No actually, scientists did actually work out how to somehow send an atom back in time- don't ask me how the hell they do it- but they did so they think in future they could make one prob not for 100's of years though.
I very much doubt it is possible though cos if a time machine could be invented we would know about it cos people would've come back??????
BUT they might have gone back to a different time so u never know- I think it's possible- well we did used to think it impossible to fly (aeroplanes) so you never know. We still dont no all the secrets of the world yet, and we never will unfortunately!

well maybe they have not made one so people in the futer have to get thinking or maybe they have a bunch of bad people thet would mess up our futer but we will never know

i am guessing that if anyone actually did they would not be able to resist going too far into the past or future to a time where they were not alive and ceased to exist

Well, it sounds highly improbable, but that doesn't make it impossible. I would hazard to guess that it is more probable than the existence of a god, and millions of people believe in that!

Maybe someone has traveled back in time already, just not to this time.....?

Well, one idea is that if they did come back, the world in which they came back would split off from the one in which they didn't. So the reality in which travellers came back in time would exist in a universe parallel to ours. When we eventually reach the time when the time machine is invented, the people who will go back will arrive in a world that splits off, and will then exist in the one parallel to ours, in which the travellers returned.

No way, time is a 1-way street. You can't go back and forth on it.

For quite some time, Ronald Mallett has been working on plans for a time machine. This technology would be based upon a ring laser's properties within the context of Einstein's Theory of Relativity.
( From Wikipedia, see the whole article at
http://en.wikipedia.org/wiki/Ronald_Mallett )

No, I believe it is impossible.

No.

If they do, then they would have (oi) sent the technology back in time
or, assuming we weren't ready for that, they would have at least warned us of several major disasters, even if in a non-direct way.
beyond that, they would have to be so callous would they still be 'people'?
unless doing so would have spawned other moral dilemmas such as what other effects that could have?
but since that decision would have already been implemented, one way or the other, then it wouldn't 'change' anything

It kinda devolves into that whole argument over predestination vs making your own decisions after the end of that strange tangle of semi-logic

but the reason -I- don't believe they will, is because we don't even observe "time." We believe it to be a linear path- but we haven't been able to form any real kind of understanding, other than that its apparently affected by gravity.

not to mention, time is an erroneous, though necessary, human perception, in my opinion.

well there is a 50% chance that yes they will but they have to use it right. Most people know the problem if we make one,well if we can make one because if we did we have to keep it away from bad people because they could kill your mom and then you wouldnt even be alive and you go up to your dad and say hi dad he would not know who the heck you are and you would be lost in a world of darkness!! but yes i do think they will make one but, when they think people are responsible to use it but first we have to find a way to make it if it is possible!!!!!!!!!!!!!!
