In January I wrote a piece titled “ 5 Physics Equations Everyone Should Know .” Lots of you weighed in with your own nominations, and there were plenty of good suggestions. So I’ve decided to do a ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the bending of space and time.

This article explores how our understanding of the universe has evolved—from the scale of everyday experience down to the Planck length ...

Cold atoms could also potentially measure much lower vacuum pressures than ion gauges can. The current lowest pressure they’ve reliably measured is around 10 -9 Pa, and NIST scientists are working on ...

Real-time features used to feel like a bonus level in an otherwise ordinary app. Now they’re the main stage. Classrooms move online at the speed of a raised hand, doctors look patients in the eye ...

What does the passage of time look like for a truly quantum object? The world’s best clocks may soon be able to answer this question, testing how time can stretch and shift in the quantum realm and ...

What is the meaning of life? Even the best of us couldn't hope to answer that question in a Universe Today article. But there are those who would try to "constrain" it, at least in terms of physics. A ...

This unsettling reality means that simply cutting emissions isn’t enough—the fight against climate change demands that researchers study all potential approaches and tools that could be used to ...

Some innovative higher-education institutions are reimagining pedagogy by prioritizing local needs over research and international student recruitment. Anna McKie visits one of them.

He added that the team learned the behaviour of their system in 15 minutes. A comparable classical method would take around 20 million years. The experiment took place in the basement labs at DTU ...
