Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

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 ...

Contemporary physics has learned to describe the universe with unprecedented precision. Yet when it tries to say what time is, it stumbles again and ...

For more than half a century, the idea that light or radio waves could suddenly reverse in time sounded like a thought experiment, not a laboratory result. Now, a series of meticulous experiments has ...

It is plausible that in the ongoing expansion, the universe is creating not only new space but also new time — and each new moment is what we... Time is elusive and enigmatic. The moment now is ...

It could be a good time event. The Sands of Time: The Physics of Time, 7 p.m., Tuesday at Marie Drake Planetarium, 1415 Glacier Ave., will cover how the concept of time is impacted by physics. The ...

An advanced laser technique has allowed researchers to observe, in real-time, the decomposition of a pollutant into atmospheric nitrous acid, which plays a key role in the formation of ozone and ...

He was a gentleman who helped create the world’s most deadly weapon; a humble man who collected as many honors as almost any man of his time. Before he died of a heart attack last week at 77, Danish ...

We’ve had quantum science on our minds all year long, courtesy of 2025 being UNESCO’s International Year of Quantum Science ...

Physics is the study of the underlying laws and mechanisms explaining how the universe works. Most of what we do in daily life is based on a principle or law of physics—dealing with forces, motion, ...
