I heard the sun is the closest star to earth and it is currently burning up and one day it is going to burn out. Is this really true? And how long will it take the sun to burn out. This is really scary though I'm sure I won't be around to witness it but how true is this?
Yes it is true. It will be in about another 3-4 billion years, so no need to start packing just yet.
Yes, the sun has completed nearly half its life and will burn out after completing the other half. And there's a lot of time, about 5 billion years till then, so no need to worry. Whether humans survive till then is a different issue altogether. First of all, conditions on earth will not be favourable many years before the sun dies, for survival. Secondly, I don't know if humans would be able to find alternate resources, as one by one they all get fully consumed. One can only wait and watch.
yes, it will happen, I wonder if the humanity would find a way for survive or if there will be any humanity to that time...
It will burn out of Hydrogen someday
yep, it certainly is
Someday the fuel is gonna burn out
All stars come to an end and that obviously includes the sun. But there will always be new ones created after supernovas and such. Humans on Earth won't survive when the sun does to an end, but by that time we'll probably be colonizing other planets.
everything will burn out eventually, in the end everything is cold still and black. actually in the end there is even less than that from what I've read.
it may be happen some day, it is a prediction, but it is true that everything have its own life cycle.
