Top quarks follow the rules of special relativity day and night. Is there a time of day or night at which nature's heaviest elementary particle stops obeying Einstein's rules? The answer to that ...

Is there a time of day or night at which nature's heaviest elementary particle stops obeying Einstein's rules? The answer to that question, as bizarre as it seems, could tell scientists something ...

On March 14, 1879, Albert Einstein was born in Ulm, Germany. His thinking revolutionized physics and turned the scientific ...

Scientists propose a relatively simple yet still complicated tabletop experiment to test the quantumness of gravity, aiming to reconcile general relativity and quantum mechanics.

Do top quarks, nature's heaviest elementary particle, obey Einstein's rules at all times of day and night? Scientists at the Large Hadron Collider have the answer.

A new essay brings us into a space of looking at what the top human minds have accomplished over the centuries, and why.

It is an extension of Einstein’s special theory of relativity – but such a massive one that it took him 10 years, from 1905 to 1915, to get from one to the other. Special relativity tells us ...
