Tachyons are a hypothetical particle generally thought to be incongruous with Einstein's theory. New measurements from an experiment near the top of an extinct Mexican volcano have placed a stringent ...

Planets orbiting dead stars known as white dwarfs might be able to remain habitable thanks to general relativity subtly altering their motion. When stars like our sun run out of fuel, they expand and ...
