There’s no reason to think that the fundamental constants have always had the value we measure today. And there’s no reason to think they’re changing either. We simply don’t know one way or the other, ...

A crucial number that rules the universe goes big in a strange quantum material. The fine-structure constant is about 10 times its normal value in a type of material called quantum spin ice, ...

Even on a black hole’s turf, an essential constant of nature holds steady. According to standard physics, the fine-structure constant, which governs interactions of electrically charged particles, is ...

Not so constant: is α different here? Is the fine-structure constant different in different parts of the universe? The answer to this intriguing question could be one step closer, thanks to a new way ...

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 ...

The fine structure constant is one of the most important natural constants of all. At TU Wien, a remarkable way of measuring it has been found—it shows up as a rotation angle. One over 137: This is ...

Electronics is really an applied branch of physics, so it isn’t surprising that if you are serious about your electronics, you probably know a little physics, too. If you’ve ever heard the term “fine ...

Over the years, many physicists have wondered whether the fundamental constants of nature might have been different when the universe was younger. If so, the evidence ought to be out there in the ...
