For scientists, learning more about how black holes behave is essential to understanding how the universe works. A recent ...

A strange “Einstein Cross” with an extra, impossible fifth image has revealed the hidden presence of a massive dark matter ...

We often marvel at the genius of Albert Einstein, a physicist who revolutionized our understanding of the universe. Yet, even ...

We all know that black holes are mysterious giants in the universe, with a mass beyond imagination and gravitational forces so strong that even light cannot escape. Our understanding of black holes ...

Today, let's talk about something mysterious and really cool — the ideas that old man Einstein came up with over a hundred years ago are now actually becoming visible! Isn't that strange?

As the universe expands, it feels like it must be spreading out from some initial point. But a physicist explains why that’s ...

Asking what existed before the Big Bang is often dismissed as meaningless, since traditional physics breaks down when pushed ...

The universe rarely fails to amaze. One of its latest surprises—nicknamed the “Einstein zig-zag”—reveals a stunning arrangement of galaxies and a distant quasar. Together, they produce a gravitational ...

From Newton’s falling apple to Einstein’s curved spacetime, our understanding of gravity has come a long way, yet this ...

Einstein’s Theory of General Relativity, an immensely important update to Newton's Law of Universal Gravitation, is currently ...

In a landmark achievement, astronomers have noticed light bending in an unexpected manner, one that doesn’t align with the predictions made by Albert Einstein’s theory of general relativity. This ...

To understand gravity, Einstein had to rethink space and time as a single connected fabric. He showed that mass bends this fabric, guiding how everything moves. NOVA is available to stream on pbs.org ...
