how's it gonna end

How will our universe end? Recent speculation now includes a pervasive growing field of mysterious repulsive phantom energy that rips virtually everything apart. Although the universe started with a Big Bang, analysis of cosmological measurements allows a possibility that it will end with a Big Rip. As soon as a few billion years from now, the controversial scenario holds, dark energy will grow to such a magnitude that our own Galaxy will no longer be able to hold itself together. After that, stars, planets, and then even atoms might not be able to withstand the expansive internal force. Previously, speculation on the ultimate fate of the universe centered on either a re-collapsing Big Crunch or a Big Freeze. Although the universe's fate is still a puzzle, piecing it together will likely follow from an increased understanding of the nature of dark matter and dark energy.

The sirens are snaking their

Way up the hill
It's last call somewhere in
The world
The reptiles blend in with the
Color of the street
Life is sweet at the edge
Of a razor
And down in the front row of
An old picture show
The old man is asleep
As the credits start to roll

And I want to know
The same thing
Everyone wants to know
How's it going to end?
-Tom Waits, "How's It Gonna End"
