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, ...

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 ...

The Compact team is also exploring how to study the topology of the universe not just with the CMB, but also by using the distribution of galaxies across the universe. Whereas the CMB provides just 2D ...

If all the information of a 3D star could be represented on a 2D event horizon, perhaps the universe — which has its own expanding horizon — was the same: A 3D projection of 2D information.

Another reason Spergel is positive the universe is flat is its rapid expansion, which is captured by the Hubble constant.Because the universe went from coming into existence as a compact ball of ...

Jeremiah Ostriker, an astrophysicist who helped set off a revolution in humankind’s view of the universe, revealing it to be a vaster, darker realm than the one we can see, ruled by invisible ...
