Antimatter. It's a thing that exists and it's something that I wanna learn more about. Just gonna jump straight into the questions this time around instead of drawing things out with a long-winded introduction.
Question 1: Why is there more matter in the universe than antimatter? Like, you can't make matter without also making an equal amount of antimatter, right? Where did it all go during the period of time right after the big bang (this is the most unreasonable question of the bunch, so if all we have at the moment are theories/guesses as to what the actual answer may be, I'll still accept them)?
Question 2: So matter and antimatter both annihilate each other upon coming into contact with each other, that's something almost everyone who knows antimatter is aware of, but like, how does this work exactly? Antimatter is LITERALLY the same as regular matter in every way, with the only difference being its opposite electric charge. How does this one little thing cause both of them to destroy each other upon contact?
Question 3: In the early stages of the universe right after the big bang, the energy density of space was high enough to support energy's spontaneous transformation into matter, and a watered-down version of this process has been replicated in particle colliders where scientists were able to create matter and antimatter particles. Despite originating from the same place however, matter and antimatter have different properties from each other (the main one of course, being the aforenamed difference in electric charge). How can antimatter have different properties from regular matter if they were both made from the same stuff as each other?
Question 4: Is antimatter a necessity for our universe to exist and be the way it is? Like, what does antimatter do for us that regular matter (or even dark matter) can't? How different would life be if antimatter straight up never existed and the entire universe was made up of only regular matter?
