So, my question arises that how do we know that normal matter is more in quantity or number than anti-matter? Research at ALPHA said that anti-matter that the spectrum of hydrogen and anti-hydrogen where exactly the same then how can we say that galaxies far away from us could be made up of normal matter?
They could just have been made up of anti-matter giving out exactly the same spectrum of light as in normal matter galaxies because of which we got trapped into this idea that there is more matter than anti-matter, whereas in reality it could be in equal amounts. And still the probability of having both in equal amount is quite less as experiments at CERN has suggested that number of anti-matter they have produced or received is less than the normal matter. Ok accepted but this ratio of anti-matter to normal matter could be 2:3 or 1:3 and not 1 part per billion. But this experiment largely depends on the axiom stating all anti-atoms will have the same spectrum as their normal matter counterparts.
Again I know this is wrong but why and which experiments contradict it? Thank you sir/ Madam for your time and reply.
