Is Anti-Matter Hiding in the Universe as Dark Matter?

[Ravi Mandavi]

Are they present in the form of dark-matter?

No. Antimatter is still regular matter, just with opposite charges. It interacts with light, and with regular matter.

Dark matter does not interact with light at all, and does not interact with normal matter at all.

And where they all gone?

You're asking about the problem of baryogenesis. This is still an open problem in physics at the moment: http://en.wikipedia.org/wiki/Baryogenesis

I can tell you that anti-matter does exist and it is present in small amounts in the universe. However, it is not present in the same quantities as regular matter. Anti-matter particles have the same mass as regular matter particles, but they have opposite charge. When matter and anti-matter particles come into contact, they annihilate each other and release energy.

Currently, we do not know where all the anti-matter in the universe is located. Some theories suggest that it may be present in the form of dark matter, which is a type of matter that does not interact with light and is therefore difficult to detect. However, this is just a theory and more research is needed to confirm this.

There are ongoing experiments, such as the Alpha Magnetic Spectrometer on the International Space Station, that are searching for evidence of anti-matter in the universe. It is also possible that anti-matter may be present in other parts of the universe that we have not yet explored.

In conclusion, while we do not know exactly where all the anti-matter in the universe is located, it is certainly present and being studied by scientists. Further research and experiments will help us better understand the role of anti-matter in the universe and its potential connection to dark matter.
