It is believed that matter, motion, gravity, and everything else we know of originated from the three dimensions of space and ...

A new, testable theory proposing three-dimensional time as the "primary fabric of everything" could help unify quantum ...

For us, that means aliens might be larger than they appear, because we would see only a three-dimensional slice of them at a time. This is exemplified in the games Miegakure and 4D Miner, where ...

As currently configured, our Bessel beam plane illumination microscope offers 3D isotropic resolution down to ∼ 0.3 μm and the ability to acquire hundreds of 3D image stacks from single living ...

One popular approach: Suppose our knowable universe is a two-dimensional plane in three-dimensional space. A solid ball hovering above the plane is invisible to us. But if it falls and contacts the ...

On a two-dimensional plane, you can imagine holding a rod fixed at one end and spinning the other end to trace out a circle. In three dimensions, the same trick works, but now the rod has more ...

The answer, in its simplest terms, is that the mathematics governing the two-dimensional plane gives rise to the laws of general relativity as it scales up into our three-dimensional universe. One ...
