Researchers Use Optical Data To Reveal The Basic Structure Of Spacetime In Rotating Frames

One of the most basic structural aspects of relativistic spacetime is the description of how time and distances are altered by motion. The theory of special relativity describes a spacetime framework for linear constant motion in which time dilates...

Testing Einstein's Theory Of Gravity From The Shadows And Collisions Of Black Holes

General relativity, Einstein's theory of gravity, is best tested at its most extreme—close to the event horizon of a black hole. This regime is accessible through observations of shadows of supermassive black holes and gravitational...

Wormholes Could Allow Travel Across The Universe, As Long As Your Spacecraft Is Microscopic

In my last post, I talked about the idea of warp drive and whether it might one day be possible. Today I’ll talk about another faster-than-light trick: wormholes. Wormholes are an old idea in general relativity. It’s based on work...

A New Approach Could Tease Out The Connection Between Gravity And Quantum Mechanics

In physics, there are two main ways to model the universe. The first is the classical way. Classical models such as Newton’s laws of motion and Einstein’s theory of relativity assume that the properties of an object such as its position...

There's No Way To Measure The Speed Of Light In A Single Direction

Special relativity is one of the most strongly validated theories humanity has ever devised. It is central to everything from space travel and GPS to our electrical power grid. Central to relativity is the fact that the speed of light in a vacuum is...
