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 ...

For more than a century, gravity and quantum physics have stubbornly resisted a common language, one describing the smooth ...

A unified Theory Of Everything is the holy grail of physics, but gravity refuses to play ball. Now, a newly proposed theory attempts to unify Einstein’s theory of gravity with quantum mechanics – and ...

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 ...

General relativity and quantum mechanics seem to describe all of observable reality. Between them, general relativity and quantum mechanics seem to describe all of observable reality.

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) ...

Physicists don’t think the truth should be “out there.” They want nature to come naturally, make sense, fit in or have a good reason not to. Unnaturalness is a problem. The poster child for unnatural ...

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 ...
