“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 ...

A new emulator is tackling the near-impossible task of mapping the universe's large-scale structure without sacrificing ...

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

Dark energy —the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the ...

From early experiments with lanterns to Einstein’s revelations about space and time, the speed of light has proven to be far ...

For more than two decades, the standard model of cosmology has stood as a reliable guide to the universe. Known as Lambda ...

Chinese astronomers have spotted a hidden supermassive black hole in the background of a peculiar gravitational wave event from a black hole merger, hinting that all three singularities were locked in ...

Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally ...

Today, let's talk about a super thrilling topic — the 'quantum singularity' at the center of black holes. It is said to be ...
