Main Question or Discussion Point
And if it does what is the mechanism and can it be used in astronomical spectroscopy?
The electromagnetic interaction with antimatter is no different than with matter. Positrons behave the same way as electrons, other than the change in sign. Antiprotrons are accelerated the same way at the LHC as protons.And if it does what is the mechanism and can it be used in astronomical spectroscopy?
The different in SIGN of the charge!If the interaction is no different then how is the spectrum detected identified to be coming from regular matter not antimatter?
