Space and time seem like two completely different ideas, but Einstein showed they are interlinked in what is known as ...

“Using newer mathematical tools, my colleague and I have demonstrated a new theory that may accurately describe the universe.

Is time something that flows — or just an illusion? Exploring space-time as either a fixed “block universe” or a dynamic fabric reveals deeper mysteries about existence, change, and the very nature of ...

Many theories are rock-solid: Scientists have just as much confidence in the theories of relativity, quantum mechanics, evolution, plate tectonics, and thermodynamics as they do in the statement that ...

A radical new theory regarding the origin of the universe suggests that gravitational waves, tiny ripples in spacetime first ...

Einstein’s theory of relativity reveals a mind-bending truth – in the right conditions, time itself slows down. This isn’t ...

If you wave your hand in front of your face, you won’t notice anything particularly interesting. Perhaps a gentle waft of air against your cheek – that’s about it. No epiphany. No major sign that ...

Mathematical quirks of our universe have led some cosmologists to wonder whether the cosmos was actually born in a black hole ...

Ten years after scientists first detected gravitational waves emerging from two colliding black holes, the LIGO-Virgo-KAGRA ...

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

Pfalzner's models show that interstellar objects — bodies ejected from other star systems — could be captured by these planet ...
