Tenets of quantum mechanics and special relativity, among other theoretical ideas, lead inexorably to string theory.

If you could take an apple and break it into smaller and smaller parts, you would find molecules, then atoms, followed by subatomic particles like protons and the quarks and gluons that make them up.

"When I was growing up, there were local heroes like Satyendra Nath Bose and Meghnad Saha who everyone in Kolkata knew," Professor Ashoke Sen recalls. Today, the 69-year-old is one of India's most ...

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 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called “Is the end in sight for theoretical physics?” Hawking, who later became my ...

NOVA: String theory's great claim to fame is that it unifies the four forces. Why is unification so important? Weinberg: Unification is where it's at. The whole aim of fundamental physics is to see ...

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 ...

Event display in the signal region from data taken in 2018. The pixel tracklet candidate with p T = 1.2 TeV is shown by the red solid line and other inner detector tracks by the thin orange lines.
