One of the unique theories of Imam Sadiq (A.S) is that everything except Allah has its opposites, but this does not result in a conflict, otherwise the whole universe would be destroyed.
This is the theory of matter and anti-matter. The difference between matter and anti-matter is that in matter the electrons are negatively charged and protons are positively charged. But in anti-matter, the electrons are positively charged and protons are negatively charged. Scientists have concluded that if one kilogram of matter collides with one kilogram of anti-matter, so much energy will be released that the whole world will be destroyed.
Professor Alfven is of the opinion that there is no other source in the universe, which can generate so much energy as quasars, except explosion of matter with anti-matter.
Just as uranium was used for exploding an atomic bomb, helium would be used for exploding matter with anti-matter. Russian scientists have already obtained anti-matter of helium.
