At half the size of Earth and one-tenth its mass, Mars is a featherweight as far as planets go. Yet new research reveals the ...

Quantum entanglement happens when two particles become interconnected and share a single state. Scientists have measured how ...

The speed of light is one of the most fundamental constants in physics, yet it has never been directly measured in one direction. Instead, scientists rely on assumptions built into how time and ...

Intuitively, we know what time is, but try to explain it, and we end up tying our minds in knots. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

No matter how many times I’ve been told (or written about) the importance of a slow run, I cannot translate it into my training. This is not to say that I am the fastest runner. My goal half marathon ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Scientists at TU Wien have uncovered that quantum correlations can stabilize time crystals—structures that oscillate in time without an external driver. Contrary to previous assumptions, quantum ...

Scientists have taken one more step down the very long road to time travel. A new paper combines the Alcubierre “warp” drive with the idea of “controlled closed timelike curves.” Though far out, ...

While passenger numbers are up so far in 2025, the $7.3 billion ‘Whoosh’ project remains far short of profitability. The newly appointed head of Indonesia’s state railway operator says that the ...

Just about anybody who played hide-and-seek as a kid remembers counting, with eyes (presumably) covered, in units of one-one-thousand. “One-one-thousand. Two-one-thousand. Three-one-thousand.” It’s ...
