Try picturing a fourth dimension. Take a few steps forward. Veer left for a second dimension, then jump up for a third dimension. Then dive off into a fourth dimension, somewhere, somehow, in a ...

In 1919, physicist Theodor Kaluza hypothesized that extra dimensions might solve some outstanding problems in physics. And ...

We live in a three-dimensional reality. Because of that, it’s pretty hard to imagine what a four-dimensional reality might be like, but that isn’t stopping physicists from trying to figure it out. A ...

Theoretical physicists believe math shows the possibilities of a fourth dimension, but there’s no actual evidence—yet. Albert Einstein believed space and time made up a fourth dimension. An example ...

Here’s what you’ll learn when you read this story: Theoretical physicists believe math shows the possibilities of a fourth dimension, but there’s no actual evidence—yet. Albert Einstein believed space ...

Does our universe have more than four dimensions -- four spatial dimensions plus time? According to some American scientists, the answer is yes. Their new theory of gravity is challenging Einstein's ...

Tony Robbin had started out as a painter. He created complex works filled with interwoven patterns and ambiguous figures to give the illusion of seeing more than one object in the same place at the ...

As 3D printing continues to revolutionize manufacturing, researchers have decided that three dimensions are not enough, and so the concept of 4D printing has begun to emerge. These four-dimensional ...
