Antimatter measured for the first time!!!
Scientists have managed to trap and measure antimatter for the first time. Physicists at CERN successfully managed to create and maintain antihydrogen for 15 minutes by combining positrons and antiprotons in a vacuum tube using extremely strong magnetic fields to prevent the antimatter from colliding with the regular matter of the container and annihilating. Positrons occupy different energy levels just like electrons in regular atoms. A laser was used to excite the antihydrogen causing the positrons to move to a higher energy level. Just like in regular atoms, when the positrons are shifting back to their original energy levels electromagnetic radiation in the form of light is given off. The results of the experiment show that antihydrogen absorbs and then reflects the same wavelengths of light as regular Hydrogen as predicted by the standard model. They are hoping to run more precise experiments but so far it looks like we won’t have to change our understanding of physics yet.
