When the sun cools off, does it signal doomsday?

Answer 1

Yes - it would. But the likelihood is the other way around - the sun is more likely to get hotter and hotter - then explode into a supernova.

Answer 2

Well when the sun cools off everything on Earth will pretty much turn into Antarctica is now.Mostly every animal would die the vegatation wouldnt grow.It would be around 50 to 100 degrees below so it would be hard to survive.But before it burns out it'll get hotter and hotter like the tropics all day and nite maybe even hotter.Then burn out but that is in like 5 millions years or so

Answer 3

No, it means our sun has run out of enough hydrogen to sustain hydrogen fusion. Our sun isn't massive enough to go supernova. Its core will contract and heat up enough to begin helium fusion.The outter layer will cool and expand to roughly the orbit of Mars in the process. This is the red giant phase of solar lifespans. Our son will most likely end its life cycle as a whitedwarf star.

Answer 4

There are supposed to be several stages that the sun will go through over great periods of time before it actually starts to cool off. It's eons away.

Answer 5

The sun goes through cycles of intensity. Right now it is in the middle of its main sequence and will burn fairly steady for another 5 billion years.

Answer 6

It will be the end for us on Earth. Our Sun is too small to super nova. It will devovle into a brown dwarf.

Answer 7

actually,we have yet years for that to happen....i hope
But whenever this happens, YES!
