What Caused the Big Bang? Consider the Beer Bottle...

It’s near impossible to comprehend the size of our universe without busting a mental cog or spraining your sense of awe. However, the origins of our universe has exactly the opposite problem: it was once mind-bogglingly small — tinier than a single particle. Physicist Lawrence Krauss explains the principle of inflation, and how within the first billionth of a second of the Big Bang, our universe increased in size by a factor of 10 to the 30th—for comparison, that’s the size of a single atom, to the size of a basketball. How did it do this? It involves a ‘frozen’ Higgs field, some cooling, and then an enormous explosion. Krauss uses an analogy we’ve all been at the mercy of: putting a beer in the freezer and forgetting it for a few too many hours. Lawrence Krauss' most recent book is The Greatest Story Ever Told -- So Far: Why Are We Here?.
