Geodesics: Einstein realized that objects in free fall follow ... This work explained the precession of Mercury’s orbit using general relativity. He formulated the correct field equations that ...

The geodesic equation describes the motion of objects moving along curved spacetime in General Relativity. The objects follow paths called geodesics, which are the closest equivalent to straight lines ...

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.

Science isn't everyone's cup of tea but when it comes to films like Interstellar (2014) (or 2020's Tenet for that matter), Christopher Nolan seems to enjoy experimenting with these scientific teas.

On 25 November 1915, Albert Einstein presented his general theory of relativity at the Prussian Academy of Sciences. This theory is still considered to be the most important idea in modern physics.

“Then why did you deposit two riyals just now?” I asked him. His answer floored me. “The ATM doesn’t allow withdrawals of less than five riyals, and I only have three in my account. That ...

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

A European Space Agency telescope has discovered its first "extremely rare" Einstein ring in a galaxy "not too far away" ...

Researchers have discovered unexpected 1D-like spin behavior in a triangular molecular lattice, challenging the conventional ...
