DARK MATTER, I'M THINKING
Astrophysicist MarioLivio’s lecture at the Univ. of South Carolina’s Hollings Library yesterday reminded me that some things are incomprehensible, such as the size of the Universe or the meaning of time. It’s taken me a while to understand that the light of stars we see at night is billions of years old by the time we see it. We’re actually looking into the past.
