Re: We now have a planet named Sedna
ok, now that I think of it, you are right - matter and energy cannot be created or destroyed, so the level of enegy in the matter of the universe will eventully reach an equilibrium - where everything is at the same energy level or temperature
but after giving this some thought, I guess the universe cant level out to absolute zero - but it will probabally be close.
All the obeservations that have been made show the universe is expanding at a speed greater then its relative escape velocity - so it will continue to expand forever
and recently scientists were all in a flutter because the expansion has been measured as increasing - the galaxies are accelerating AWAY from each other faster and faster - which we cannot explain with observable physics - they only explaination they have been able to come up with it the phantom 'dark matter' which has anti-gravity properties.
The more you learn about quantum and astrophysics, the more it disturbs you - its as if the universe is only a simulation in the mind of God- its too bizzare to be real :^)
