PXReality

The biggest questions about reality, answered so the whole family gets it.

Are we aliens? Is time real? Could we be living in a simulation? Join Dr. PX, a curious explorer with a backpack and far too many questions, on animated adventures through space, physics and the strangest ideas in science. Each video takes one big question and makes it simple, funny and true.

For curious minds of every age. Every fact is checked, every source is listed under the video, and when science doesn't know yet, we say so.

PX stands for Parallax: look at something from a new angle and you can tell how far away it really is. That is how astronomers measured the distance to the stars, and it is how we look at reality.
