String theory is perhaps the most high-profile candidate for what physicists call a theory of everything – a single ...

B y now, just about everyone has heard of string theory. Even those who don’t really understand it–which is to say, just about everyone–know that it’s the hottest thing in theoretical physics.

Scientists have long sought evidence to refute string theory, but a new test seeks to disprove key aspects with help from the ...

In contrast, string theory posits that the basic constituents of matter are not point-like particles but one-dimensional entities – strings – whose vibrational modes give rise to the variety ...

Thirty years ago, Witten opposed string theory. He now believes these tiny stringlike loops of energy could be the universe’s basic form of matter and energy and that some strings could reach ...

A lot of people, when they learn about String Theory for the first time, are taken aback by what a beautiful, powerful idea it is. When we look at our Universe and discover the way it is, we find ...

The invisible string theory became popular on TikTok in 2023, but the concept has been around for years. Bronstein tells PEOPLE that it's unknown when the term was coined, but it does have ties to ...

Unlike the Standard Model, which treats elementary particles as point-like, string theory proposes that they are actually tiny, vibrating, one-dimensional objects called strings.

The string theory model underlying monstrous moonshine was nothing like the particles or space-time geometry of the real world. But Cheng sensed that the new moonshine, if it was one, might be ...

The problem with string theory, according to some physicists, is that it makes too many universes. It predicts not one but some 10 500 versions of spacetime, each with their own laws of physics.
