Before our universe existed, another one may have collapsed in on itself, and some of its black holes may have survived the ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

A tiny discrepancy in particle physics has loomed for decades as an exciting possible crack in one of science's most ...

Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research.

Max Planck revolutionized physics with quantum theory and championed doubt as the driving force of scientific progress.

In the quest to unravel the mysteries of the universe, physicists are revisiting a 150-year-old theory that could illuminate why matter prevails over antimatter. This knot hypothesis, originally ...
