Scientists behind a theory that the speed of light is variable - and not constant as Einstein suggested - have made a prediction that could be tested.
There's been a whirlwind of commentary of late speculating that the acceleration of the expanding universe might not be real after all.
Researchers have created a 3D printed cosmic microwave background - a map of the oldest light in the universe - and provided the files for download.
Five years ago, the Nobel Prize in Physics was awarded to three astronomers for their discovery, in the late 1990s, that the universe is expanding at an accelerating pace.
It takes a very, very clean room to build a detector sensitive enough to see the light from the beginning of the universe.
A team of astrophysicists at the University of Portsmouth have created the largest ever map of voids and superclusters in the universe, which helps solve a long-standing cosmological mystery.
Reaching the magnetic South Pole is a travel destination few people get to check off their bucket list. But two University of Melbourne PhD students did just that while also indulging their interest in classic physics experiments.
The universe is not spinning or stretched in any particular direction, according to the most stringent test yet.
An experiment to explore the aftermath of cosmic dawn, when stars and galaxies first lit up the universe, has received nearly $10 million in funding from the National Science Foundation to expand its detector array in South ...
The very idea that a black hole could have a temperature strains the imagination. I mean, how can something that absorbs all the matter and energy that falls into it have a temperature? When you feel the warmth of a toasty ...
