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.

A new hypothesis suggests that the universe may be twice as old as we had believed. Observations from the James Webb Space Telescope provide new information on the rate of the universe’s expansion.
Researchers had college students and AI take a standardized test in creative thinking, and all of them were scored by trained evaluators who didn’t know in advance that some had been completed by AI.
The United States and Russia, the two biggest nuclear powers, have no imminent plans for talks on a nuclear deal. That should change, writes a former US diplomat.
The trailer for ‘Oppenheimer’ fails to include female physicists, which is indicative of a broader media trend that, if reversed, could lead to greater gender diversity in science.
Bright, flickering galaxies called quasars were thought to pose a problem for our understanding of the cosmos – but new research shows Einstein was right yet again.
Upgrades to the hardware and software of the advanced observatory should allow astrophysicists to detect much fainter gravitational waves than before.
Your experience of time is relative because it depends on motion – more specifically, your speed and acceleration.
Black holes can have a mass equivalent to that of millions of suns. Other, smaller, black holes can combine the mass of Mount Everest into the size of an atom.
Nothing is harder to find than you might think.
A multitude of experiments have shown the mysterious phenomena of quantum mechanics to be how the universe functions. The scientists behind these experiments won the 2022 Nobel Prize in physics.
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.
