“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 ...

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

Seeking endorsements for her new book, Chanda Prescod-Weinstein finds herself staring at fundamental questions of space, time ...

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

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 ...

When LIGO detected gravitational waves unleashed from two colliding black holes for the first time in science history, it set off a whole new era in astronomy.

When black holes collide, they release gravitational waves. The waves contain information on the collision. If one black hole is much heavier, the waves vary with the observation angle.

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 ...

Out on a remote tract of land in Hingoli district of Maharashtra, well away from busy towns and cities, work is on to set up ...
