Will universe remain in utter darkness if all the stars emptied down there fuel?

Question

at some time,one by one all the stars in universe are out of hydrogen ,then they turns to a red giant and remain so for some time.Then in the next stage they turned into a white dwarf and finally in the cooling process emptied down all of its thermal energy.Though this process may take billions of years but a time will arrive when the universe has no natural source of light& so utter darkness prevails everywhere..

Answer 1

well it depends on the star as if what will happen to it when it dies but the unvierse will just keep creating more stars its a never ending process..... just look at any nebula where stars are born...

Answer 2

No, we'll still have moonlight.

Answer 3

What you describe is a theory called the Big Chill....where the Universe continues to expand, all stars die out (brown dwarfs being the last), the last of the light fades and all is dark.  This is only a theory, however one that I agree with.  It's billions (and billions) of years away though.

Answer 4

um...i thought stars imploded when they ran out of fuel...creating another star in its place

Answer 5

Hm. Good explanation. But. We'd probably all be dead by then...=[  

Answer 6

Yes.  The universe will not last forever (based on current knowledge).   Scientists aren't yet sure exactly how the universe will end, but you're pretty close.  

Answer 7

Yes, if it lasts long enough the universe may end in "heat death" many kalpas from now. In the meantime, stars that die seed space with materials that can coalesce to form new stars, so the universe will continue to glow with new stars long after all the current stars are gone. But eventually, entropy will win, and there won't be enough of a concentration of energy to fire up any new stars. In the past, some cosmologists thought the universe might eventually be pulled back together by its own gravity, possibly initiating something like another Big Bang. This was called the Big Crunch. These days, given that the expansion of the universe appears to be accelerating under the influence of the mysterious Dark Energy, cosmologists are more likely to anticipate the Big Rip, in which space expands so rapidly that eventually even matter itself is torn apart. Current predictions are that this will happen long before heat death.

Answer 8

It's a little more complicated than that, but the short answer to your question is "YES".

Assuming the universe is open and destined for "heat-death", the most likely given our current knowledge and observations, as time passes, stars will burn out. The largest, brightest, hottest ones will burn out first, followed by the more sedate ones. Some of the matter from dead stars can be recycled into new stars - for awhile at least - but there's only so much raw material (hydrogen) in the universe, and when it's gone, it's gone. There might still be a few red dwarfs burning when the universe is 250 trillion years old (it is now about 15 billion.)

When those stars are gone, the only sources of light will be the occasional flash of radiation as various debris falls into black holes, or, much, much later (around 10^65 years), the light produced every now and again when a black hole dissipates through the Hawking radiation. When all the black holes are gone (around 10^100 to 10^110 years), assuming the protons have decayed as theory suggests, then the unverse willl be a cold, thin sea of radiation, with perhaps a few forlorn particles mixed in. Entropy will be at a maximum, the temperature will be the same everywhere (asymptotically approaching absolute zero), and no further work, reactions, emissions of light, etc. will be possible anywhere.

Answer 9

I guess so, but you also have to take into consideration that as we speak new stars are being born and others are dying. It's an endless cycle. The stars that die leave the stuff that new stars need to be made, and eventually gravity takes hold and you have a new star.
