Researchers are using machine learning, symbolic regression, and high-performance computing to explore and classify string ...

In the late 19th century, classical physics seemed complete. Scientists believed they had uncovered all the laws governing ...

Orthodox quantum mechanics is empirically flawless, but founded on an awkward interface between quantum systems and classical ...

A team of scientists is proposing a bold alternative to the Big Bang theory, suggesting that our universe may have instead formed inside a colossal black hole.

The general theory of relativity, Einstein asserted, was now complete. The month leading up to the historic announcement had been the most intellectually intense and anxiety-ridden span of his life.

Noether’s theorem Noether’s eponymous theorem was inspired by Albert Einstein’s work on relativity in the early years of the 20th century, culminating in his general theory of relativity in ...

The Theory of Relativity in Our Daily Life Although it may seem like a theory far removed from our daily lives, Relativity is fundamental to many modern technologies. A practical example is GPS, which ...

For example, we encounter problems in constructing the Hilbert space, writing the constraint operators, and finding their spectrum. Also, the fact that general relativity is a generally covariant ...

OGRe is a modern Mathematica package for differential geometry and tensor calculus, designed to be both powerful and user-friendly. It can be used in a variety of contexts where tensor calculations ...

This paper is devoted to the investigation of the energy-momentum problem in two theories, i.e., General Relativity and teleparallel gravity. We use Einstein, Landau-Lifshitz, Bergmann-Thomson and ...

Not only has general relativity merged with quantum physics into a single theory, the graviton dynamics describe in this hybrid concept, it continues within unruly spacetimes such as inside black ...
