At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it?

In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called ...

Physicists have determined that most of the universe is dark matter -- invisible to us but affecting the universe anyway.

String theory is a hypothetical idea that purports to be a theory of everything, able to explain the fundamental microscopic aspects of all of reality, from the forces of nature to the building blocks ...

A recent experiment at Fermilab has delivered intriguing results that challenge standard predictions, adding fuel to the ...

Since the 1980s, string theory has emerged as the leading candidate for achieving every physicist’s dream: reconciling general relativity with quantum mechanics and thereby finding a tidy explanation ...

Brian Greene is one of the foremost scientists and science communicators of our time. Greene, a theoretical physicist at Columbia University, has been working for decades to advance our understanding ...

String theory is a purported theory of everything that physicists hope will one day explain … everything. All the forces, all the particles, all the constants, all the things under a single ...

And so we don't have any possible experiments on the horizon that could tell one theory from the other theory. And since the particle view of physics has been tested by experiment and is accepted, the ...

After 60 years, this beautiful theory hasn't produced many tangible results. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Paul M. Sutter is an ...

String theory proposes that the fundamental constituents of the universe are one-dimensional “strings” rather than point-like particles. What we perceive as particles are actually vibrations in loops ...
