Re: Just a side note
Please don't mix up Dark Matter and antimatter. The latter is real, it can be measured and it can be created - both has been done several times already.
So far so good.
Antimatter is just an atom, whose core contains the electrons while the orbits are filled with protons - in "normal" matter it is the other way around.
Not even close. Antimatter is made up of particles the same as those making up normal matter but with reversed charges. Insted of protons, neutrons in the core, plus associated electrons, you have antiprotons and antineutrons, plus positrons.
Dark Matter on the other hand is currently just a place holder for something yet unknown. It could turn out to be many different phenomenons
Just so. But ...
Phenomena: plural
Phenomenon: singular
Phenomenons: not a word at all. You may be thinking of "pheremones" (which, among other things, are said to make people randy) or "phenomenal melons" (which apparently do the same thing).
