Through a field called geometric topology, mathematicians like me study all possible spaces in all dimensions. Whether trying ...

There are suggestions that life could not take place in a 2D (plus time) universe, meanwhile, because of insufficient complexity. The main argument, which would make 2D universes a non-starter, ...

The Fermi National Accelerator Lab near Chicago has a new toy: the Holometer. As its rather fancy name suggests, the Holometer is for testing whether our universe is actually a 2D hologram that's ...

And if we, ourselves, as 3D creatures, decided to enter their 2D Universe, we would be such an odd sight, since they could only see “2D slices” of us at any given moment.

Do we live in a 2D hologram? There's no short answer, but physicists believe it may be possible. The holographic principle-- a property of particle physics' string theory -- proposes that ...

An ongoing experiment could reveal whether or not our full and fleshed-out 3D universe is an illusion, a 2D projection onto a cosmic screen beyond our perception or understanding. The Holometer ...

First, a quick recap: Holographic duality can show us what's inside a black hole because it suggests the 2D universe is connected to the 3D universe via mathematics. We just have to construct an ...

A new experiment could reveal whether or not our full and fleshed-out 3D universe is an illusion, a 2D projection onto a cosmic screen beyond our perception or understanding.
