Sean Carroll will be talking about quantum a little bit, but what he really wants to get across is the idea that in our everyday lives, in the days we go trough, in the things we experience the world around us, we’re actually feeling the effects of the much larger universe in which we live.

In particular, what happens to us in our kitchens. We can take an egg and turn it into an omelet, but it’s very hard to take an omelet and to turn it back into an egg. That is a remnant of the fact that we live after the big bang, and the big bang was a very special event.

As you see there is an arrow of time, the time has a direction. We all agree on the difference between yesterday and tomorrow, as far as we know everywhere in the universe we can observe, we have the same feeling which day was yesterday and which day will be tomorrow.

Big Ideas presents Sean M. Carroll of CalTech discussing how the direction of the arrow of time was defined by the Big Bang. He also speculates about what might have come before the Big Bang.
