The new findings come from the Dark Energy Spectroscopic Instrument (DESI), which sits on a telescope at the Kitt Peak ...

The largest-ever three-dimensional map of the cosmos, plotting out some 15 million celestial objects, could help reveal the ...

Scientists are homing in on the nature of a mysterious force called dark energy, and nothing short of the fate of the ...

From 3-D to 4-D It's difficult for us to accept ... To extend the curled-up space to include these added dimensions, imagine that spheres replace the Kaluza-Klein circles. Instead of one added ...

Einstein's special relativity, established in 1905, unified space and time into a four-dimensional continuum. It relies on two core principles: Galileo's relativity and the constancy of light's speed.

Electrons moved in two dimensions when influenced by a magnetic field, hinting at how a similar effect would occur in the fourth dimension.

In the Randall-Sundrum braneworld model, the fourth dimension of space changes how gravity operates on small scales, which changes the rate at which small black holes form and evaporate.

The concept of higher spatial dimension extends our familiar three-dimensional space—length, width, and height—by introducing additional directions which are perpendicular to all three.

One of the weirdest theories in cosmology is the holographic principle, the idea that our universe is a three-dimensional image projected off a two-dimensional surface — the idea that, yes, we are ...
