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, ...

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 ...

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

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

New strategies may soon allow scientists to test dark energy theories within our own solar system, linking cosmic-scale physics to local observation. Science advances through a cycle of proposing ...

The theoretical physicist and best-selling author finds inspiration in politics and philosophy for rethinking space and time.

Centuries before anyone pointed a telescope at the sky, Isaac Newton figured out how gravity works. He showed that any object ...

Theoretical physicist Alex Lupsasca is pushing for a space telescope to glimpse the thin ring of light that is thought to surround every black hole.
