Recent theoretical advances have underscored the significance of momentum space geometry in the realm of relativistic physics. Traditional notions of flat momentum space are being re-evaluated in ...

Quantum field theories are powerful tools for particle physics and condensed matter physics but are rarely used in plasma physics. However, in warm-dense regimes, where matter is partially ionized and ...

The Terrell-Penrose effect, predicted in 1959, suggests that objects moving at speeds close to that of light appear rotated. This optical illusion results from the combination of relativistic length ...

Cormac O’Raifeartaigh reviews The Perfect Theory: a Century of Geniuses and the Battle Over General Relativity by Pedro G Ferreira Fighting it out: an artist's impression of two black holes circling ...

Yesterday, I wrote about the core concepts needed to understand quantum physics, which is one of the two pillars of modern physics. The other, of course, is the theory of relativity, the full and ...

Gravitational physics has become a truly experimental science as tests of the special and general theories of relativity reach new levels of precision Right on time When I was a first-term graduate ...

Relativistic physics imposes one of the most frustrating limitations predicted by science. It tells us that an inescapable speed limit exists in the universe: we can't go faster than the speed of ...

Among the intriguing issues in plasma physics are those surrounding X-ray pulsars -- collapsed stars that orbit around a cosmic companion and beam light at regular intervals, like lighthouses in the ...

Einstein's 1915 theory of gravitation (General Relativity), is now considered one of the pillars of modern physics. It contributes to our understanding of cosmology and of fundamental interactions ...

Since 2007, physicist Leonard Susskind has regularly delivered a lecture series called the Theoretical Minimum, on the foundations needed to study different areas of ...

I've been trying to explain quantum physics, forces, relativity, and space-time to my kid and we had a question that I'm finding difficult to find a solid answer to. Background you can skip if you ...
