An experiment that reaches across our galaxy has detected the first signs of a possible ‘sea’ of ripples in space-time

Scientists might have discovered the first signs of the gravitational-wave background: a sea of ripples in space-time reverberating throughout the universe. Albert Einstein first predicted the existence of gravitational waves. They have recently been detected following violent collisions of black holes and neutron stars. By monitoring dead stars throughout our […]

Einstein thought we’d never detect ripples in space-time. But 100 years later, a remarkable experiment is proving him wrong over and over.

Albert Einstein predicted that extremely massive objects, like black holes and neutron stars, send out ripples in space-time when they collide. Einstein didn’t think humans would ever detect these ripples, called gravitational waves. But the Laser Interferometer Gravitational-Wave Observatory (LIGO) proved him wrong 100 years later. Now a global network […]

A collision in space revealed a black hole that physicists thought could never exist. The observatory that detected it cracked a 100-year-old mystery posed by Einstein.

Summary List Placement Seven billion years ago, two black holes crashed into each other and merged into one enormous black hole with the mass of 142 suns. The collision reverberated through space and time, and these ripples – a phenomenon called gravitational waves first predicted by Albert Einstein – travelled […]

Black holes can produce light when they collide, new research shows — astronomers just saw the first-ever ‘flare’ from a spacetime-bending merger

Two black holes crashed together and merged in a violent collision that bent space and time, sending gravitational waves towards Earth. The Laser Interferometer Gravitational-Wave Observatory detected those ripples in spacetime, and a California telescope picked up a flash of light from the same spot. The flare marked the first […]

Scientists detected ripples in space and time from a potentially new class of collision in the universe. Their observatory cracked a 100-year-old mystery posed by Einstein.

Large collisions in space, like those between black holes or neutron stars, create ripples in space-time called gravitational waves. The phenomenon was first predicted by Albert Einstein. The Laser Interferometer Gravitational-Wave Observatory(LIGO) recently sensed gravitational waves from a collision of two neutron stars – the second such event ever detected. […]

The most awe-inspiring scientific discoveries of the 2010s include the first image of a black hole, an exoplanet with water, and a hidden continent

Astronomers, anthropologists, geologists, and many other scientists have made mind-boggling breakthroughs in the last 10 years. Some highlights include work that produced the first image of a black hole, traced what happened to the Neanderthals, and discovered potentially habitable planets outside our solar system. These are 41 of the biggest […]

An experiment that solved a 100-year-old mystery posed by Einstein just got up to 50% more powerful by squeezing light

Large collisions in space, like those between black holes or neutron stars, create ripples in space-time called gravitational waves that were first predicted by Albert Einstein. The Laser Interferometer Gravitational-Wave Observatory first detected gravitational waves in 2015. LIGO and its partner in Italy, called Virgo, have been detecting waves from […]

The movie ‘Interstellar’ came out exactly 5 years ago. Since then, new discoveries have changed our understanding of black holes.

Director Christopher Nolan’s Hollywood blockbuster “Interstellar” just celebrated its fifth anniversary. In the movie, Matthew McConaughey plays an astronaut who journeys into a supermassive black hole called Gargauntua. To make “Interstellar” scientifically accurate, Nolan hired physicist Kip Thorne to render the most realistic depiction of a black hole possible. But […]

A huge explosion sliced through our galaxy just 3.5 million years ago, as human ancestors walked the Earth. Scientists think it was nuclear activity in the black hole at the Milky Way’s centre.

NASA‘s Hubble Space Telescope revealed the remnants of a huge explosion near the supermassive black hole at the centre of our galaxy, which occurred just 3.5 million years ago. In galactic timescales, that’s recent. Ancient human ancestors lived across Africa at the time. Video of an artist’s interpretation shows how […]
