A new quantum recipe for black holes could be the first step toward a theory of "quantum gravity", the "holy grail" of ...

The idea of a particle that races faster than light has long fascinated physicists. Known as the tachyon, it was originally ...

In a nutshell A physicist proposes that time has three dimensions instead of one, which could finally unite quantum mechanics ...

The Big Bang theory is wrong and the universe is sitting inside a black hole, scientists have suggested. Since the 1930s – when Belgian theoretical physicist Georges Lemaitre proposed the universe ...

The Big Bang is often described as the explosive birth of the Universe – a singular moment when space, time and matter sprang into existence.

Discover how Einstein’s theory of special relativity reshaped physics by linking space, time, mass, and energy in a universe governed by the speed of light.

"A snapshot of relativistic motion: Special relativity made visible." ScienceDaily. ScienceDaily, 5 May 2025. <www.sciencedaily.com / releases / 2025 / 05 / 250505121748.htm>.

His third paper introduced his ‘Special Theory of Relativity’ which revolutionised the classical concept of space and time. Einstein illustrated his concepts through ‘thought experiments’: ...

These superluminal particles, are the "enfant terrible" of modern physics. Until recently, they were generally regarded as entities that did not fit into the special theory of relativity.

They can do this thanks largely to Albert Einstein’s 1905 theory of special relativity, which explains how speed affects time and space. In this application, a person on Earth looking out into the ...
