Strangely behaving matter could one day explain some of the mysteries of space.

An astrophysicist explains what wormholes are and how these theoretical space-time tunnels have popped up in the solutions to a set of decadesold equations.
Albert Einstein might have the answer.
Antisemitism has been used as a weapon against leading Jewish politicians in Europe for over a century – no matter how assimilated they were. Ukraine’s Volodymyr Zelenskyy is no exception.
Time dilation might seem like science fiction, but it’s not. There are astronauts circling the Earth right now who are experiencing it – though luckily nowhere near as much as Buzz Lightyear.
Theories exploring the possibility of time travel rely on the existence of types of matter and energy that we do not understand yet.
There’s a special type of particle called a ‘tachyon’ which would have to travel faster than the speed of light. But here’s the hitch – we can’t prove tachyons even exist.
Scientifically speaking, for time travel to exist, so must parallel timelines. This theory addresses the paradoxes that arise when studying the possibility of time travel.
A total eclipse that travelled the full width of Australia in 1922 offered astronomers the chance to confirm Einstein’s theory of general relativity - and for the community to enjoy a rare spectacle.
Astronomers watched a pair of pulsars for 16 years to test the theory of general relativity, which has stood unchallenged for over a century.
Advanced technologies and the information they collect have revealed how black holes form and behave.
Energy isn’t really made of anything else. It’s a kind of capacity to do things
Such a mission could be developed soon, allowing astrophysicists to take selfies of the solar system and use the Sun’s gravity as a lens to peer deep into space.
In trials teaching Einsteinian physics in schools, our most astonishing discovery was that children were not astonished: they just took the ideas in their stride.
Gravity is something every person on Earth intuitively understands: It is what keeps you on the ground. But how come gravity pulls down, rather than pushes up? Einstein came up with the answer.
A century after publishing major papers in theoretical mathematics, German-born Emmy Noether continues to challenge and inspire mathematicians with her story and mathematical legacy.
Einstein was awarded a Nobel prize for his explanation for how light can be described as being made up of individual particles of energy under certain conditions.
We first encountered the letter in 2019, when a reader shared it with us. In it, Einstein discusses bees, birds and whether new physics principles could come from studying animal senses.
If humanity wants to travel between stars, people are going to need to travel faster than light. New research suggests that it might be possible to build warp drives and beat the galactic speed limit.
If we want real public understanding of new findings, we must also open up peer review.
