Even though we can explore the universe with great precision, there is still a lot we don't know, according to Ulf Danielsson, professor of theoretical physics at Uppsala University. Besides doing ...

Interstellar object 3I/ATLAS has seemingly confirmed Einstein's general relativity by exhibiting gravitational lensing as it neared the Sun. However, the observed light bending exceeded predictions by ...

In the mid-19th century, Bernhard Riemann conceived of a new way to think about mathematical spaces, providing the foundation ...

Whenever someone talks about black holes, they almost always talk about the event horizon and the singularity. After all, ...

A team of physicists led by Mir Faizal argues the universe cannot be simulated, saying reality includes non-computable truths beyond any algorithm or AI model ...

According to general relativity, closed timelike curves could theoretically enable time travel. These curves, which loop back ...

Spacetime isn’t something that exists; it’s a model for describing how events happen. Treating events as objects creates philosophical confusion and fuels misconceptions, such as time-travel paradoxes ...

Physicist Mir Faizal, Adjunct Professor with UBC Okanagan’s Irving K. Barber Faculty of Science, was not out to shatter the ...

Learn about two black hole mergers in 2024 that experts revisited with new information from gravitational waves, confirming theories made by Albert Einstein.

A question that has vexed physicists for the past century may finally have a solution – but perhaps not the one everyone was ...

Two Caltech historians associated with the Einstein Papers Project have gathered together what they consider to be the most important of Einstein's ...

For the first time, scientists have detected two black hole mergers with spins so unusual they may reveal a new generation of ...
