Gravity is mathematically relatable to dynamics of subatomic particles

Albert Einstein's desk can still be found on the second floor of Princeton's physics department. Positioned in front of a floor-to-ceiling blackboard covered with equations, the desk seems to embody the spirit of the frizzy-haired ...

Bizarre 'dark fluid' with negative mass could dominate the universe

It's embarrassing, but astrophysicists are the first to admit it. Our best theoretical model can only explain 5% of the universe. The remaining 95% is famously made up almost entirely of invisible, unknown material dubbed ...

Stephen Hawking's final book suggests time travel may one day be possible – here's what to make of it

"If one made a research grant application to work on time travel it would be dismissed immediately," writes the physicist Stephen Hawking in his posthumous book Brief Answers to the Big Questions. He was right. But he was ...
