We’ve been told by science that the universe is expanding relentlessly, driven by a mysterious force called dark energy.

The shape of the cosmos depends on a balance of two competing forces: the pull of gravity and the expansion driven by dark ...

Today we are going to talk about cosmology and the fact that black holes were considered as an almost unbelievable idea. In the 30s, British astronomer Arthur ...

Scientists believe that in the very early universe, everything was incredibly tiny, chaotic, and full of random energy ripples, known as quantum foam. It was a state where spacetime was unstable, and ...

New data from major dark-energy observatories suggest the universe may not expand forever after all. A Cornell physicist calculates that the cosmos is heading toward a dramatic reversal: after ...

Just as ocean waves shape our shores, ripples in space-time may have once set the Universe on an evolutionary path that led to the cosmos as we see it today. A new theory suggests gravitational waves ...

Physicist Sean Carroll explains how physics, astronomy, philosophy, and classics all help us understand the expanding ...

A physicist proposes that the universe is not empty space, but is a viscous fluid, fueling the expansion and contraction we see.

The new study used the known distance to a galaxy called M106/NGC 4258 — a spiral galaxy in the constellation Canes Venatici — as a reference point. The universe is expanding faster than astronomers ...

Scientists are rethinking the universe’s deepest mysteries using numerical relativity, complex computer simulations of Einstein’s equations in extreme conditions. This method could help explore what ...
