Antimatter is matter that we don’t encounter very much in everyday life. This form of matter is different to the stuff we see around us. In simple terms, antimatter is matter that carries an opposite ...

The laws of physics, as experts currently understand them, dictate the following: Every fundamental particle has an antimatter twin. The electron, quark, and muon, for example, are paired with the ...

ALPHA published a paper in the journal Nature this week that reports the first ever measurement of the optical spectrum of an antimatter atom. The team behind the paper says that this is the result of ...

For the first time, and contrary to popular belief, scientists measured the vibrational structure of hydrogen and helium atoms by X-rays. The results disprove the misconception that it’s impossible to ...

WITH the continuous spectrum described by Lyman (Astrophysical Jour., 60, 1) as a background, and with hydrogen flowing through the receiver of the spectrograph, it was found possible to photograph ...

Hydrogen’s antimatter counterpart has shown its true colours, and they are just what physicists ordered. Antihydrogen atoms are made of a positron (a positively charged version of the electron) ...
