Most of us first hear about the irrational number π (pi)—rounded off as 3.14, with an infinite number of decimal digits—in ...

Scientists are testing a novel way to measure cosmic expansion using time delays in gravitationally lensed quasars. Their ...

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

A subtle timing flash may expose the Unruh effect. The approach ties ordinary lab tools to deep quantum physics. Researchers ...

By establishing a larger principle for how things shatter, certain energy-intensive tasks could gain an advantage.

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

How the world of the smallest particles is structured, what is known about fundamental forces, and what particles have to do ...

In this video, we walk through the process of calculating the coefficient of friction and the force required to move a block. Using clear examples and step-by-step explanations, you'll gain a solid ...

The video explains that due to their high surface area to volume ratio, air resistance limits an ant's acceleration, allowing it to reach a low terminal velocity that is generally non lethal, ...

Forget Greenwich Mean Time or Eastern Daylight Time, scientists say we need a brand new time zone - for Mars.
