No. The heating bills alone would be killer.

There are so many reasons why not. The top two are the explosion (or implosion) caused by the sun's ceasing to be, and the extreme cold that comes with not having a heat source (as intimated in the first answer). Other reasons such as "what would we orbit" also bearing thinking about.

It's not really a matter of whether we would be able to survive on Earth so much as whether there would be an Earth to survive on. When the sun finally decides to kick the can, it's taking us with it.

No, assuming hypothetically you meant that the Sun didn't destroy Earth in the process of extinguishing itself, without the sun plant life would cease to exsist which would break the food chain and cause a mass extinction of all mammals and also there would be an etreme super severe ice age of temps well below the ammount needed to liquify oxygen...nothing could survive....

here is an awesome answer to your question here! http://www.exitmundi.nl/exitmundi.htm go to sun burnout and check it out! (it's on the left side panel)

No, Not unless humans evolved to withstand temperatures at minus 273.16 degrees C (zero degrees Kelvan)

Nup... this would start the chain of noplants to no plant eaters, to no carnivores.... etc

Yes. Humans could survive without the sun. Our main resource from the sun is light and heat. Without the sun there is no light and heat however there is plenty of heat stored in the Earths core. It would be easier to live underground and most of the population would but some would live above ground but life above ground would be like living on the moon. There would be large and many earth bases that would even be connected to the underground cities. And even the ocean would not entirely freeze because of the really hot volcanic vents on the sea floor. So it is very possible for the Human race to survive without the sun by being self sustaining. Like the movie MATRIX But the human race is not self sustaining yet.

Too chilly, no?! ;-)

I would say that it depends on how much warning we had. If we had enough warning, then I think that it would be possible for a small fraction of our species to survive, at least for a time. We would have to build enclosed communities that are powered by nuclear power. Without the sun there would not be any energy to drive wind or water movements so, forms or power generation that rely on these would not work. With the limited amount of oxygen created from the hydroponic farms that we would have to build, I doubt that we would be able to afford to burn fossil fuels. So, that basically just leaves nuclear power. This power would have to be able to provide for ALL of our energy needs. This would include lighting (not just for us but for the hydroponic farms, industrial, and heating. We could also probably eventually make use of geothermal energy for heating, but that would be rather limited as to the locations where that would be feasible. I don't see such communities as being able to be very large, so most of Earth's population would probably have to be abandoned to freeze to death. This would be if we had time to prepare. If we did not have time, if w just woke up one morning and the Sun was not there, then I don't see anyway to set up the needed infrastructure to sustain any life on this planet.

1) "The sun provides more than just energy, it provides the gravitational force that keeps us in orbit. But I interpret the question to mean "What if the sun stopped shining?" In that situation, Earth's surface would cool down to a state in which the outgoing infrared radiation is balanced only by conductive heat from Earth's interior. The heat content of the atmosphere is negligible except on the very short time scale of a few days. Within days to a week, Earth's surface would cool to below the freezing point of salty water, and the oceans would begin to form a complete ice cap. In a year or so the temperature would be down below 200 degrees absolute at the surface (that's roughly minus 100 Fahrenheit). The water in the deepest part of Earth's oceans would freeze after 1,000 years. Earth's surface would not cool all the way to its new stable state of around 30 degrees absolute (approaching minus 400 Fahrenheit) until millions of years had elapsed. This state is one in which the radioactive heat in Earth's interior balances outgoing radiation. In the interim period of several million years, Earth's subsurface would be kept warm because of the slowness of heat conduction through solid rock or ice. So the inside would stay warm even as Earth's atmosphere was freezing out as solid oxygen and nitrogen. Interestingly, this means that bacteria that live well beneath Earth's surface might survive for a while, though life right at Earth's surface would be extinguished very rapidly on a time scale of years or less. A small number of people could survive a long time by drilling and creating a habitat deep down (miles below Earth's surface)."

The other gas planets would soon join and then we would have enough mass to ignite and create a little dwarf star and voila! Earth will have a new body to orbit again. And before our energy reserves deplete, we would hopefully refine our helium 3 reactors technology and use it to process helium 3 fusion and we could use the space shuttle to transport the fuel from its source (the moon) back to earth. We will all live indoors and in underground corridors we would build to connect every building so that we could avoid the frigid cold outside. At least until we can build gigantic heat exchangers to warm up our air. Yes, that is exactly what will happen. Luckily we will have the help of the Xarganthian Empire, but they will later betray us and sell the property of our planet to the Endlochiarghs. We will then be shipped off to the Chruptan quadrant of the galaxy where we will be kept in cryogenic pods for 74 centuries as the Chrupto-Endlochiarghs work through the legal wranglings of the import. Finally an emergency will necessitate our thawing as an encroachment of the tyrant Sahddahm Huhseihn draws nigh. The certainty of the existence of innumerable weapons of negative-mass destruction completes the decision to send the humans in as cannon-fodder as the attack upon the Eirackee Empire ensues."

Why does everyone think a nuclear-power sustained society must be small? Why does everyone think we would need to go underground? a) build large monolithic domes suitable to contain whatever PSI we had decided to live at (probably less than the 15 PSI we live at now) b) spray foam insulation onto it until a suitable R-value is reached Cost for such buildings on cheap land could be less than that of traditional office space within our current cities. The cost of the insulation need not be prohibitive. Ridgid Foam board from Home Depot would cost about $20/ft^2 at R250. At R250 you would lose less than 2 BTU per external FT^2 / hr (assuming outside was almost absolute zero) and your building would need only cooling.

It is not entirely clear that humans can perpetually survive on earth even WITH the sun. But without it, we would quickly die of starvation and cold. We would lose our atmosphere too, as the temperature dropped and the gasses condensed. Life on this planet without the sun would be about like life in space with the added benefit of still having gravity. We're not very good at living in space either, and haven't been able to do so sustainably. The space station, skylab, etc all depended on regular shipments of food and fuel and clearing of waste.

yes in my opinion,air is more needed.
