Trap antimatter for 16 minutes

alpha-cern The Alpha experiment of the European Laboratory for Particle Physics (CERN) has managed to trap antimatter atoms for more than 1,000 seconds, around 16 minutes , which will allow them to start studying their properties in detail, according to an article published in the journal Nature Physics .

In total, the scientists managed to catch 300 anti-atoms, which will allow to make an accurate map of antihydrogen, the antimatter version of hydrogen , using laser or microwave spectrography, and compare it with the hydrogen atom. A hydrogen atom consists of an electron bound to a proton, while in antihydrogen a positron (the "mirror" of the electron) is associated with an antiproton.

Thanks to this feat, experts now have "enough time" to be able to study antimatter, as well as find out how gravity influences an antimatter atom. The experiment's spokesman, Jeffrey Hangst of Aarhus University, said he plans to make accurate measurements of the trapped antihydrogen "before the end of the year."

A ray of light contains more information than you think

A simple ray of light, a jet of photons, is capable of giving us information about the temperature, composition, speed and distance of the star that emitted it.

The legacy of Albert Einstein: the Theory of Relativity

On this day Albert Einstein was born in Germany, author of the theory of relativity, who determined that the laws of physics are the same for all non-accelerating observers.

An asteroid that was going to hit Earth in 2023 turns out to be...

For a few days in January, asteroid 2022 AE1 became the most dangerous asteroid observed in more than a decade.

This is theory that says what was there before the Big Bang

One of the problems with physics is that its two great theories, general relativity and quantum theory, get along like a cat and a dog. Although we have been searching for a quantum theory of gravity for more than half a century, the truth is that the results are quite disappointing.

Is there only one time?

Time is a concept that we use daily throughout our lives. However, what is it? Time, we say, is what the clock ticks. But that is not saying much. If we reflect a little more we will see that no matter how hard we try to find an answer, none will completely satisfy us. Time is an elusive concept and it is surprising that something so familiar is so difficult to define.
