This Video Explains The Complex Holographic Universe

Our current 3+1 dimensional universe may be described as resulting from a spacetime one dimension lower.

PBS Space Time explores our universe's most outer reaches to bring us exciting videos. Now, this clip goes over the holographic universe.

"We live in a universe with 3 dimensions of space and one of time. Up, down, left, right, forward, back, past, future. 3+1 dimensions. Or so our primitive Pleistocene-evolved brains find it useful to believe. And we cling to this intuition, even as physics shows us that this view of reality may be only a very narrow perception. One of the most startling possibilities is that our 3+1 dimensional universe may better be described as resulting from a spacetime one dimension lower – like a hologram projected from a surface infinitely far away," says the video's description.

All of this analysis started with black holes, explained show host Matt O'Dowd. We won't give you the details here, you have to watch the video for that. We will tell you that the concept of a holographic universe will finally make sense, no matter how complex.
