String Theory. The heterotic string naturally produces SO (32) or E_8 x E_8 gauge symmetry in ten dimensions [4], requiring compactification on a six-dimensional manifold to recover four-dimensional ...

Add Yahoo as a preferred source to see more of our stories on Google. String theory attempts to unify general relativity and quantum theory. Popular in the 1990s, string theory fell out of favor as it ...

Physicists may have uncovered a surprising new clue that string theory—the idea that the universe is built from unimaginably tiny vibrating strings—could be more than just a mathematical fantasy.

With just a handful of assumptions, string theory stands alone. Based on the idea that all subatomic particles are made up of vibrating strings of energy, string theory is a candidate for a “theory of ...

String compactification refers to the process of reducing the ten or eleven dimensions intrinsic to string or M-theory down to the four dimensions of observable spacetime by assuming that the extra ...

String theory and its extensions propose that the elementary constituents of matter are not point particles but one-dimensional strings whose vibrational modes manifest as observed particles and ...

This work develops a geometric framework for understanding quantum decoherence, entropy production, and the emergence of the arrow of time from higher-dimensional physics. The central object of the ...

What if every person you meet, including those you’ve yet to cross paths with, is quietly tethered to you by a single thread you can't even see? That's the premise of the invisible string theory. The ...

Does string theory—the controversial “theory of everything” from physics—tell us anything about consciousness and the human brain? If you're enjoying this article, consider supporting our ...

In October 1984 I arrived at Oxford University, trailing a large steamer trunk containing a couple of changes of clothing and about five dozen textbooks. I had a freshly minted bachelor’s degree in ...

The idea that the universe is made of tiny vibrating strings was once the science theory du jour. String theory promised to unite the disparate theories describing particles and gravity, and many ...
