Nope, not quite. Planets revolve around their suns because of the force of gravity. When suns supernova - like ours will in an estimated 4-8 billion years - they incinerate their planets as they break apart. Even if they turn into black holes eventually that runs out of energy and they become stardust again.AArdvark wrote:Well, if energy cannot be made into matter then it's a one way street. Matter becomes energy but not energy becomes matter. Given enough time the entire universe will be all energy.
Eventually the universe will degrade to absolute zero and motionless stardust. No light, no energy, no time, just quiet, dead space.
And stardust. As so it was in the beginning it shall be again.
Just like Hillary Clinton did, one day the universe will lose and it will all be over.

Well, that's a recent discovery. Everything I had heard said eventually the sun will expand outward and incinerate all the planets in its general area including earth, then either collapsing into something or bursting like a balloon.Billy Mays wrote:Our sun does not have enough mass to become a supernova according to Subrahmanyan Chandrasekhar and NASA.Tdarcos wrote:When suns supernova - like ours will in an estimated 4-8 billion years...
Since the general consensus as I understood it was the sun was going to have some sort of explosive event incinerating at least everything as far as Mars, I thought it was.
But whether or not it will technically "supernova," as it is my understanding it is eventually going to destroy everything within about 150-200 million miles, is a distinction without a difference.

The "Chandrasekhar limit" was discovered in 1930.
Yes, our Sun will cook everything alive and boil the oceans as it transitions to a Red Giant in the next 5.5 billion years, before transitioning into a White Dwarf and cooling down for trillions of years.Tdarcos wrote:Everything I had heard said eventually the sun will expand outward and incinerate all the planets in its general area including earth, then either collapsing into something

That is absurd.
Trying to figure out whose "general consensus" this could possibly be is making my brain hurt.Tdarcos wrote:Since the general consensus as I understood it was the sun was going to have some sort of explosive event incinerating at least everything as far as Mars, I thought it was.

There is no gray area when it comes to supernovas, they are a thoroughly defined event.

It is actually a distinction with a huge difference for the purposes of understanding our universe.
