I have read your fascinating article on the phenomenon of superluminal shadows in astronomical contexts. It is truly captivating to explore these cosmic curiosities. However, I would like to point out ...

Astronomers have detected a gargantuan blast of energy from space that appears to be doing the impossible: Traveling seven times faster than the speed of light. This is, of course, an optical illusion ...

Find out how traveling faster than light and traveling back in time are the same thing. By choosing the right path and the right reference frames, any superluminal motion can lead to information or ...

The fact that the speed of light is constant is one of the cornerstones of physics. Nothing carrying information can travel faster than the speed of light, but by playing with geometries physicists ...

Astrophysicists Jon Hakkila of the College of Charleston and Robert Nemiroff of the Michigan Technological University have published research indicating that blasts that create gamma-ray bursts may ...

Geraint Lewis receives funding from the Australian Research Council. The story of the drawn-out development of Albert Einstein’s revolutionary rewrite of the laws of gravity has been told many times, ...

In a groundbreaking exploration of physics, researchers have revealed a way to extend Albert Einstein's special theory of ...

Constructor Theory is the ability to see the deepest underlying facts about the world. The people behind the greatest leaps in physics - Einstein, Newton, Heisenberg, all had the uncanny ability to ...

Blasts that create gamma-ray bursts may actually exceed the speed of light in surrounding gas clouds, but do so without violating Einstein's theory of relativity. Astrophysicists Jon Hakkila of the ...
