Space and time seem like two completely different ideas, but Einstein showed they are interlinked in what is known as space-time. Here's what it means!

One of the greatest challenges of modern physics is to find a coherent method for describing phenomena, on the cosmic and microscale. For over a hundred years, to describe reality on a cosmic scale we ...

Few ideas in modern science have reshaped our understanding of reality more profoundly than space-time: the interwoven fabric of space and time at the heart of Albert Einstein’s theory of relativity.

What if our biggest idea about reality is built on a hidden misunderstanding? A new philosophical look at space-time challenges the popular view that the past, present, and future all exist together ...

A nuclear engineer reacts to PBS Space Time’s wild application of Einstein’s equations, exploring the physics behind the ...

Exploring the BTZ black hole in (2+1)-dimensional gravity took me down a fascinating rabbit hole, connecting ideas I never expected—like black holes and topological phases in quantum matter! When I ...

Physicists hope that understanding the churning region near singularities might help them reconcile gravity and quantum mechanics. At the beginning of time and the center of every black hole lies a ...
