>It's perhaps worth stopping to ask why astrophysicists hypothesize dark matter to be everywhere in the universe? >To explain observations of galaxies inconsistent with general relativity, the existence of dark matter was posited as an unknown and invisible form of matter calculated to make up more than a quarter of all mass-energy content in the universe Food for thought: the best current evidence of dark matter is the Bullet Cluster[0]. In particular, look at this picture: https://upload.wikimedia.org/wikipedia/commons/a/a8/1e0657_scale.jpg https://upload.wikimedia.org/wikipedia/commons/a/a8/1e0657_s... At first, these were two blobs of dark matter and gas. They collided. That resulted in what we see now: the dark matter portions (purple, measured by gravity lensing) magically went through each other (because dark matter is weird like that) while the gas portions (pink) actually collided and formed a shockwave (like normal matter behaves), with much of the gas remaining in the middle. The tone in the article quotes there makes it seem like dark matter is some esoteric rounding error, but that seems like pretty "solid" evidence for... the anomalous mass readings we call dark matter. 0: https://en.wikipedia.org/wiki/Bullet_Cluster https://en.wikipedia.org/wiki/Bullet_Cluster
