the heat death of the universe

Postby kensaundm31 on August 13th, 2011, 7:35 pm 

Hi,

Im not studying anything but I read cosmology books watch a lot of documentaries.

I read a book about black holes being the last things left at the 'end of the universe', as they slowly evaporate.

But I've also heard it said that energy doesnt die, but changes form.

Is not the heat death of the universe the death of energy?

PS. If this isnt the place to ask random noob questions, could you direct me to a forum where it is?

Cheers.

What this really means is that the heat death of the universe is when the energy becomes totally homogeneous...that there are no remaining concentrations of energy. The stars burn out, the black holes evaporate, and everything is a uniform bath of photons of with a black body spectrum as if emitted from a very cold body.
