Is the universe 13 billion years old? 6,000? How can you tell?

Ethan Siegel tells you how in his wonderful piece How you can figure out the Age of the Universe!

Ethan Siegel is a theoretical astrophysicist at Lewis & Clark College in Portland, OR.

I follow his blog as he posts detailed explanations to everyday astronomical and astrophysical questions.

Just remember: The Universe doesn't care what you think of it,  and as the late Carl Sagan said: The Universe was not made for us.
