String theory is perhaps the most high-profile candidate for what physicists call a theory of everything – a single ...

Simulations based on Einstein’s theory of relativity test scenarios that might have preceded the Big Bang, to observe the ...

One of the problems of string theory is that five different versions of it exist! Four of these are theories with closed strings, which can be visualised with elastic bands that move in space-time.

Scientists have recently uncovered portal-like structures in space that could revolutionize our understanding of the universe ...

“How quantum mechanics and gravity fit together is one of the most important outstanding problems in physics,” Kathryn Zurek, ...

At the time, physicists found themselves facing a crisis: the two most important ideas of 20th century physics, relativity and quantum theory, were known to be fundamentally incompatible.

They have always been my living proof of the invisible string theory — that they are intertwined across time and space, I have no doubt of.

Technical Terms Moduli Space: A parameter space representing all inequivalent solutions or configurations, often describing vacuum states in string theory.

Generations of researchers have tried to create a quantum theory of gravity, and their work has produced sophisticated ...

Conventional string theory’s predictions are incompatible both with the observation of dark energy, which appears to be causing our universe’s expansion to speed up, and with viable ...

Huge Galaxy String Challenges Space TheoryAn enormous string of galaxies 300 million light-years long has been discovered in the remote Universe, challenging existing theories about how the ...
