Life Faces Cosmic Energy Crisis »
Posted By charbarred 1 year, 5 months ago in Science & TechnologyLooking at the long term, the cosmos isn't shaping up well for sentient beings or any other living things. 100s of billions of years from now, the universe will start to run short of radiant energy--better known as heat - one of the necessities for life. However, 2 physicists have concluded there will be a small consolation...

I have to say that I'm not worried.
In approximately 5 billion years Sun will expand into a red giant large enough to engulf orbits of nearby planets including Earth. And even if Earth is not swallowed by the Sun, then Earth's biosphere will be completely destroyed by excess solar radiation as Sun depletes it's hydrogen supply.
But all in all, I'm confident that mankind will destroy ourselves even before then, unless a rogue comet or an asteroid will prevent that from happening, which would be quite disappointing.

What the physicists may not have completely internalized is that 90% of the universe is stuff that we can't see. This was a discovery made in the last 10 years - although certainly someting the mystics have been trying to tell us for a long time.
Trying to predict more than 100 years ahead is bad enough. 100 billion, given the uncertainty in current theories of cosmology, is to make a leap of faith.
