Time to them us not the fourth dimension – to them the fourth dimension is just another spatial dimension. So, what we experience as time, they just experience as another dimension of space.

But those three dimensions are far from all there are. There's a fourth dimension that's just as important, even though it's very different: time.

“Time is 'separated' from space in a sense that time is not a fourth dimension of space. Instead, time as a numerical order of change exists in a 3D space.

A trippy fringe theory suggests that time is the source of all physical matter, and space is merely a byproduct. According to Gunther Kletetschka, a geologist from the University of Alaska Fairbanks, ...

Even if we can't actually experience a fourth dimension ourselves, they think reaching for the fringes of it could offer valuable lessons that we can implement right here in the 3-D world we live in.

By making time part of the physical fabric of a universe that, as far as we can tell, began in a big bang some 13.8 billion years ago, Einstein’s theory of general relativity implies that time ...

“The fourth dimension is time. It’s not just the three-dimensional structure but what molecules are doing in time,” said Samuel I. Stupp, a chemist at Northwestern University who spoke about ...
