Why does something exist instead of nothing?
#AskEthan
We all know that the fact that the Universe exists has made a lot of people angry since the dawn of people.
But how did our Universe come to have "something" instead of nothing?

Ask Ethan: Why does something exist instead of nothing?
Perhaps the most remarkable fact about the Universe at all is simply that it, and everything in it, exists. But what's the reason why?

We think of physical reality as what objectively exists, independent of any observer. But relativity and quantum physics say otherwise.

Why ice skating is a miracle of physics
