The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at ...

Observing the flow of time at the quantum scale reveals a puzzling energy phenomenon: the energy required to simply read the ...

There is an important and unresolved tension in cosmology regarding the rate at which the universe is expanding, and ...

The white pickup truck pulls up to a decommissioned space observatory on top of Mount Blue Sky, one of Colorado’s famous “14ers,” mountains that reach more than 14,000 feet high. The scene is stark on ...

They captured an instant in time, but the moment was blurry. That may sound like the lyrics to a sweet but ultimately nihilistic song from the grunge era, but in fact it appears to be one possible ...

Scientists working on Fermilab's Muon g-2 experiment released the world's most precise measurement yet of the magnetic moment of the muon, bringing particle physics closer to the ultimate showdown ...

The weak gravitational pull on a particle just half the mass of a grain of sand has been measured for the first time. This most precise measurement of its kind is a breakthrough towards the quantum ...

A new measurement of a fundamental particle called the W boson appears to defy the standard model of particle physics, our current understanding of how the basic building blocks of the universe ...

Electrons are really, really round. A new measurement confirms the subatomic particle’s spherical shape to a record level of exactness, physicists report in the July 7 Science. That near-perfect ...

The laws of physics imply that the passage of time is an illusion. To avoid this conclusion, we might have to rethink the reality of infinitely precise numbers. Strangely, although we feel as if we ...
