This story is part of a special package being published this week about the barriers Black physicists face and potential models for change. Read more C. Smith/Science Roy Clarke missed the freewheeling atmosphere of the legendary Bell Telephone Laboratories after he left Bell to join the physics faculty at the University of Michigan (UM), Ann … Read more

What’s Inside a Black Hole? Quantum Computers May Be Able to Simulate It

by

Both quantum computing and machine learning have been touted as the next big computer revolution for a fair while now. However, experts have pointed out that these techniques aren’t generalized tools – they will only be the great leap forward in computer power for very specialized algorithms, and even more rarely will they be able … Read more

Wonky black hole suggest we don’t understand how cosmic behemoths work

by

We thought black holes rotated in the same plane as their orbit. One that is tilted by at least 40 degrees suggests our understanding of their behaviour needs an update Space 24 February 2022 By Alex Wilkins Artist impression of the X-ray binary system containing a black hole (small black dot at the centre of … Read more

Physics Breakthrough as AI Successfully Controls Plasma in Nuclear Fusion Experiment

by

Successfully achieving nuclear fusion holds the promise of delivering a limitless, sustainable source of clean energy, but we can only realize this incredible dream if we can master the complex physics taking place inside the reactor.   For decades, scientists have been taking incremental steps towards this goal, but many challenges remain. One of the … Read more

Atomic Clocks Experiment Reveals Time Dilation at The Smallest Scale Ever

by

In his theory of general relativity, Einstein predicted something called time dilation: the notion that two clocks under two different gravitational pulls will always tick at different speeds.   The effect has been observed in many experiments since, but now scientists have recorded it at the smallest scale seen so far. The result was achieved using … Read more

Atomic clock experiment shows Einstein’s general relativity is right

by

Physicists have measured time dilation on the smallest scale ever using an atomic clock made of thousands of ultracold atoms formed into a stack of pancake-shaped blobs Physics 16 February 2022 By Alex Wilkins Time dilation has been measured inside a tiny atomic clock Jacobson/NIST The world’s most precise atomic clock has confirmed that the … Read more

How Olympic Figure Skaters Break Records with Physics

by

Today’s figure skaters are performing feats of athletic prowess that were unimaginable only a few decades ago. At the Winter Olympics in Beijing last week, U.S. skater Nathan Chen took home the gold with short program and free skate performances packed with quadruple jumps and triple Axels. And 15-year-old Russian skater Kamila Valieva became the … Read more

Alex Keshavarzi interview: How muons could reveal exotic new physics

by

Precision measurements have long suggested that particles called muons, closely related to the electron, are misbehaving. Now, it seems their shenanigans might be pointing to the presence of new particles Physics 9 February 2022 By New Scientist Jennie Edwards FOR decades, physicists have been aware of a gnawing anomaly in the behaviour of a mysterious … Read more
