I’ve hear before that the big bang wasn’t really an explosion, more of the point in time where the universe started rapidly expanding. Can someone explain where the all the matter that makes up planets, stars, etc. came from?

Just dropping in a hypothesis that may freak some of you out.
So you know in extreme cases like right after the universe began quantum fluctuations can produce matter and antimatter pairs of particles. (You may have geard about virtual particles, its nonsense.) So these matter and antimatter particles would have cancelled but the universe inflated quickly and femtometers became light-years. These particles got so far away from each other that there is no way they can eliminate. So there you have it the universe is symmetric its just that some of the matter and antimatter got blown away from each other and formed galaxies and clusters of galaxies. Where there were more matter like here we ended up with things being matter. Where antimatter was more abundant it formed antimatter things. Since both matter and antimatter behave the same way there is no difference on larger scales all interactions play out the same.
Just so you know it is very possible that distant galaxies are actually antimatter. And we have no way of knowing for sure.
