When was the Big Bang?
– Barbara Russell
Thanks to the work of a lot of astronomers and observatories, including Keck, we can answer that one… The Big Bang was 13.75 ±0.11 billion years ago.
Modern astronomy has allowed us to answer questions that have been asked for as long as curious humans have looked at the universe around us. Curiosity as expressed in a poem is part of what we are as humans. That is why we build and maintain the big telescopes. Thanks Barbara!
