The gravitational field can affect space and time: the stronger gravity is, the slower time moves. This prediction of General Relativity can be used to reveal hidden forces acting on dark matter.
Einstein’s theory of general relativity suggests that our universe originated in a Big Bang. But black holes, and their gravitational forces, challenge the limits of Einstein’s work.
To detect dark matter, you need to build an ultra-sensitive detector and put it somewhere ultra-quiet. For one physics collaboration, that place is almost a mile under Lead, S.D.
The Euclid mission is preparing to launch on July 1.
A spacecraft set to launch this year will throw a spotlight on the mysterious ‘dark side’ of the universe.
For decades physicists have argued over the nature of the elusive dark matter that pervades the Universe. A clever new study uses gravitational lensing to bring new evidence to the debate.
The most energetic events in the universe shower us with unbelievably energetic particles of light. Capturing these can help us to solve some enticing cosmic mysteries.
Astronomers have found that mysterious dark energy may originate in black holes.
By spotting and counting tiny galaxies, we can work out how much dark matter is hiding in the cosmos.
A glowing blob in the sky known as “the cocoon” may be caused by pulsars in the Sagittarius dwarf galaxy.
A comparison of star-forming galaxies suggests, surprisingly, that dark matter and visible matter do interact – taking us closer to understanding what keeps the galaxies together.
Regular matter makes up just one-sixth of all the matter in the universe. What would it mean to finally understand what makes up the rest?
Recent results cast doubt on dark matter.
There’s a perfectly good alternative to dark matter, but most scientists aren’t keen on the idea.
Time ends when the universe does.
Advanced technologies and the information they collect have revealed how black holes form and behave.
The James Webb Space Telescope is set to launch into orbit in December 2021. Its mission is to search for the first light to ever shine in the universe.
Astronomers know a lot about what’s in outer space – and think it’s possible it never ends.
Plus new research finds a way to speed up the search for dark matter. Listen to episode 4 of The Conversation Weekly.
