New measurements using gravitational lensing suggest the universe’s current expansion rate does not agree with signals from the early cosmos.

From a particle smasher encircling the moon to an “impossible” laser, five scientists reveal the experiments they would run ...

A closer look at Atlas’s unconventional get-up motion shows how the robot tests balance and hardware before committing to a ...

Clocks tick faster on Mars than they do on Earth, in part because Mars experiences less gravitational pull from the Sun. Now scientists have calculated just how much faster -- 477 microseconds, on ...
