What is string theory: It replaces point-like particles with tiny vibrating strings, requiring extra dimensions to reconcile gravity with quantum mechanics. Why it matters: String theory could unify ...

String theory found its origins in an attempt to understand the nascent experiments revealing the strong nuclear force. Eventually another theory, one based on particles called quarks and force ...

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 ...

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 ...

String theory began over 50 years ago as a way to understand the strong nuclear force. Since then, it’s grown to become a theory of everything, capable of explaining the nature of every particle, ...

In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical ...

The idea of String Theory is that our Universe came from a higher-dimensional, more symmetric, more complex state with an enormous number of degrees of freedom. In order for String Theory to be solved ...

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 ...

At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it? String theorists, this one may be for you. The theorized object warps spacetime ...
