From Bad Astronomy
During my live video chat I was asked, where is the center of the Universe? Someday, someone will ask an easy question. :-) But this is a good one, and the answer is a little weird.

instead of the 2d ant thing just ask the question

where is the center of the surface of the earth?

We see the leftover radiation of the big bang in ALL directions when we look out into space. It's call the cosmic microwave background radiation.

Then what is the reference point for speed in space? For speed on Earth we can use the surface of the Earth as a reference point for speed, and in our own solar system we can use the Sun, but at what speed is the Sun moving? And in reference to what? And what does that make of the speed and direction of motion of the Earth? And us? So are we really moving? or is everything moving around us in reference to our own perception?
