Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...
Even given a set of possible quantum states for our cosmos, it's impossible for us to determine which one of them is correct ...
Explore how forces and friction work to hold a block against a vertical wall. This video explains normal force, frictional force, and equilibrium conditions, showing how these forces balance to ...
The video examines how a game’s physics engine responds when its rules are deliberately pushed beyond normal use. By contrasting standard mechanics with exploited behavior, it reveals unexpected ...
Can a small lump of metal be in a quantum state that extends over distant locations? A research team at the University of Vienna answers this question with a resounding yes. In the journal Nature, ...

Researchers have achieved quantum "alchemy" that allows them to alter the properties of materials using high-powered ...
Some forces are called contact forces because they require objects to touch. One is tension force, found in stretched wires. Another is the force found in a spring. And last are resistive forces: ...
Recent integrative approaches suggest that physics cannot be adequately characterized by magnitude-based distinctions alone, such as those implied by Big-P, little-p, and mini-p physics. While these ...
Former Air Force Secretary Frank Kendall on Monday rejected Navy Adm. Frank Bradley’s reasoning for launching a second strike on a vessel in the Caribbean as two wounded survivors clung on to the boat ...
A new picture of the interstellar comet 3I/ATLAS has caused a lot of surprise and confusion among scientists. This comet is special because it came from outside our solar system, and only two such ...
