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

For once, beer is going to clarify your understanding. Theoretical physicist Lawrence Krauss lays down the empirical evidence for the mechanics of the Big Bang.

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?.
