What is the difference between Dark Matter and Anti-matter?
Answer Dark matter is the name given to the unknown kind of mass needed to explain the observed features of galaxies that can’t be accounted for with ‘regular’ mass. Anti-matter is exactly the same as ‘regular’ matter except that it has an opposite electrical charge. For example, the electron has a negative electrical charge while its anti-matter twin, called a positron, has a positive electrical charge. When anti-matter and matter come into contact they instantly and completely annihilate each other. As for wormhole equations, this website is a good source.
