Does string theory—the controversial “theory of everything” from physics—tell us anything about consciousness and the human ...

In an unprecedented step, researchers crafted a detailed model compatible with the universe’s accelerated expansion.

For more than a century, scientists have wondered why physical structures like blood vessels, neurons, tree branches, and ...

Eight decades have passed since physicists realized that the theories of quantum mechanics and gravity don’t fit together, and the puzzle of how to combine the two remains unsolved. In the last few ...

The Standard Model of our universe doesn’t match the evidence, in part because of dark energy, a ghostly force pushing the ...

String theory strutted onto the scene some 30 years ago as perfection itself, a promise of elegant simplicity that would solve knotty problems in fundamental physics—including the notoriously ...

String theory has finally made a prediction that can be tested with experiments -- but in a completely unexpected realm of physics. The theory has long been touted as the best hope for a unified ...

String theory is an attempt to unite the two pillars of 20th century physics — quantum mechanics and Albert Einstein's theory of relativity — with an overarching framework that can explain all of ...

For decades, physicists have been trying to combine quantum physics and general relativity into a single, unified theory. One of the leading contenders is string theory, an elegant vision in which ...
