For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the bending of space and time. Quantum mechanics governs the world of particles ...

Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe’s greatest mysteries. The most widely accepted theory currently suggests ...

Why does light carry energy even though it has no mass? This video explains the real physics behind photons, energy–momentum relationships, and how light can transfer energy and momentum without mass.

Nuclear fusion, the process that powers every star in the observable universe, has moved from theoretical physics into the realm of real laboratory results. On December 5, 2022, scientists achieved ...

There are hints that the universe may be behaving unexpectedly, and astrophysicists are racing to explain why. Their ideas to account for the surprising result include allowing dark matter and dark ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

Recent advances in quantum technologies are rapidly emerging as powerful tools for pushing the boundaries of High Energy Physics (HEP), offering innovative paradigms for simulating quantum field ...

Light can hit a lead halide perovskite crystal that is anything but pristine and still end up as useful electric current. That mismatch has bothered solar researchers for more than a decade. Silicon ...
