String Theory vs. M-theory: Showdown to Explain Universe | RealClearScience In the early 1990s, string theory was in a bit of a theoretical pickle. For decades, theorists had poured their hearts and ...

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 ...

Paul M. Sutter is an astrophysicist at SUNY Stony Brook and the Flatiron Institute, host of Ask a Spaceman and Space Radio, and author of Your Place in the Universe. String theory is a hypothetical ...

Cosmology 'The chances of you living 50 years are very small': Theoretical physicist explains why humanity likely won't survive to see all the forces unified Astronomy Astronomers map one of the ...

In 1998, astronomers discovered dark energy. The finding, which transformed our conception of the cosmos, came with a little-known consequence: It threw a wrench into the already daunting task of ...

In string theory, a paradigm shift could be imminent. In June, a team of string theorists published a conjecture which sounded revolutionary: String theory is said to be fundamentally incompatible ...

While investigating how string theory can be used to explain certain physical phenomena, scientists at the Indian Institute of Science (IISc) have stumbled upon on a new series representation for the ...

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. But ...
