Some great Mind Blowing responses from a recent Ask Me Anything with Neil DeGrasse Tyson.

"Photons have no ticking time at all, which means, as far as they are concerned, they are absorbed the instant they are emitted, even if the distance traveled is across the universe itself."

"1) The fact that an electron has no known size -- it's smaller than the smallest measurement we have ever made of anything.

2) That Quarks come only in pairs: If you try to separate two of them, the energy you sink into the system to accomplish this feat is exactly the energy to spontaneously create two more quarks - one to partner with each of those you pulled apart.

3) That the space-time structure inside a rotating black hole does not preclude the existence of an entire other universe.

(When asked about his favorite fact about the Universe) - "That is will never end. That it's on a one way trip of expansion. Something that many find to be philosophically unsettling. My view is that if your philosophy is not unsettled daily then you are blind to all the universe has to offer."
