Reports of the death of the Big Bang have been greatly exaggerated. Big Bang theory is alive and well. At the same time, our universe may not have a beginning or end.
Are you seeing the stories this week suggesting that the Big Bang didn’t happen? According to astrophysicist Brian Koberlein – a great science communicator at Rochester Institute of Technology with a popular page on G+ – that’s not quite what the new research (published in early February 2015 Physics Letters B, has suggested. The new study isn’t suggesting there was no Big Bang, Koberlein says. It’s suggesting that the Big Bang did not start with a singularity – a point in space-time when matter is infinitely dense, as at the center of a black hole. How can this be? Koberlein explains on his website:
The catch is that by eliminating the singularity, the model predicts that the universe had no beginning.
