I’m not entirely 100% dark matter exists in galaxies the way often described. … The way I see it, it might as well be a repulsive force between galaxies opposed to the current understanding of it being am attractive force. Plus, if it were a phenomenon that pushed things apart, it could also explain Dark Energy.
And to me, that’s a perfectly valid theory. Like other proposed explanations for dark matter or dark energy or “whatever the hell it is we can detect the effect of but can’t identify”, it’s difficult to test.
That’s why I enjoy science. It’s like a big puzzle, and sometimes you get halfway done and realize you put it together wrong and have to start over.























Same. Which explains why I (twice, lol) incorrectly used the terms “theory” and “hypothesis” interchangeably when those are totally different things in sciences.
