Traditional black holes, as predicted by Albert Einstein's theory of General Relativity, contain what are known as ...

Like stretch marks left on skin that expanded too quickly or cracks embedded in freezing ice, cosmic strings are artifacts of what the universe looked like in the moments before it rapidly changed ...

Euclid space telescope sent some images back to Earth during an early testing phase. While reviewing the pictures, astronomer ...

Euclid, a space telescope on a mission to uncover the secrets of dark matter and dark energy, has already made a stunning discovery: a perfectly formed Einstein ring hidden in a well-known galaxy.

The Einstein ring, formed as light from a distant galaxy bends to glow around another object in the foreground, could help ...

The Einstein ring was discovered when Collett and his team studied NGC 6505, an oval-shaped galaxy located around 600 million ...

For over a century, quantum mechanics and Einstein’s general relativity have stood as the cornerstones of modern physics, yet ...

A theoretical particle that travels faster than light, the tachyon has long intrigued physicists and fueled decades of speculation. Initially conceived as a possible solution to quantum and relativity ...

The theory is a series of equations defined by Einstein. These equations combine space and time to create space-time. Gravity is explained by these equations, which are consistent with what we see ...

The scare quotes serve to remind us that, according to the special theory of relativity, even the concept of ‘at the same time’ isn’t well defined for points far apart in space, as Einstein ...
