AALTO, Finland — Scientists have potentially solved what many consider physics’ most challenging problem – reconciling Einstein’s theory of gravity with quantum mechanics, without adding any new ...

Waterloo scientists have developed a new way to understand how the universe began, and it could change what we know about the Big Bang and the earliest moments of cosmic history. Their work suggests ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

A jarring divide cleaves modern physics. On one side lies quantum theory, which portrays subatomic particles as probabilistic waves. On the other lies general relativity, Einstein’s theory that space ...

Gravity is by far the weakest of nature’s four fundamental forces, and physicists have spent decades asking a deceptively ...

Just three numbers—that’s all it takes to completely, unequivocally, 100 percent describe a black hole in general relativity. If I tell you the mass, electric charge, and spin (i.e., angular momentum) ...

A group of physicists just built a tiny model of a wormhole on a quantum computer and sent a qubit — a quantum unit of information — through it. It’s a tiny step, but it could be the first step toward ...

I rarely write much about it in my research papers, but every piece of science I have ever done either assumes the correctness of general relativity – our most fundamental theory for explaining ...

Solving Einstein's equations by using quantities that apply across all space and time coordinates could enable physicists to eventually find their 'white whale': a quantum theory of gravity. In ...
