Two Experiments Show Fourth Spatial Dimension Effect

To the best of our knowledge, we humans can only experience this world in three spatial dimensions (plus one time dimension): up and down, left and right, and forward and backward. But in two physics labs, scientists have found a way to represent a fourth spatial dimension.

Physicists Discover New Kind of Matter: Excitonium

Excitonium sounds like a made-up substance from a children’s graphic novel. But it is an actual scientific word, coined 50 years ago to describe new a type of matter, which scientists believed should exist, but weren’t able to prove-until now. Physicists at the University of Illinois said that they have now proven that excitonium really …

What Lies Beyond The Edge Of The Observable Universe?

You’ve probably read about how the Universe is expanding, and has been expanding since the beginning of time. Over the course of 13.8 billion years or so, it’s stretched from the size of a billionth of a proton to the vast, unknowable expanse it is today. In fact, recent research suggests that it’s actually expanding faster than our current laws of physics can explain, and that’s kind of a problem.
