so the other comment reply does nothing to explain, but there’s too much mis- and disinformation that people consume and too much prideful ignorance to just let a comment sit like this as the top of the “hot” algorithm to not give people an entry point to enlighten themselves.
dark matter is not named for its undetectibility within the visible light spectrum. you are correct that we cannot detect much matter within the universe based on the visible light spectrum. dark matter is named based on that we cannot detect it at all. dark matter is more the answer to a question we don’t yet know how to answer. there are a lot of behaviors out there in the cosmos that cannot be explained through the simple interactions between matter that we are able to observe, leading many scientists to theorize that much of the universe, around 70% of it, is made of a form of matter that interacts with the kind of matter we are by just kinda… pushing it away (not like anti matter which causes waveform collapses when interacting with the kind of matter we are).
a competing theory for why the cosmos acts the way it does is because space time itself is expanding as a result of our observable universe existing on the inside of a black hole. my estimation is probably that both explanations contain part of the truth and that the whole truth is that both dark matter exists and our universe is inside a blackhole. if you want a real mind trip, i suspect our universe is inside a blackhole inside our universe, and that every blackhole in the universe contains a universe. filled with blackholes with universes, including the very same universe that contains that blackhole
Dark energy is used to explain the rate of expansion of the observable universe. Dark matter is used to explain observed anomalies in the rotations in some galaxies. For general relativity and Newtonian gravity math to work, there has to be something we can’t observe. Einstein had added a cosmological constant to relativity, that he later called his biggest mistake, but turned out to be very useful.
what else would matter look like in space? isn’t it all black–all dark?
this is just an uneducated observation but modern geniuses don’t accomplish much other than coming up with buzzwords.
I will delete my reply if you delete your comment, you sound extremely foolish and this is embarrassing for you.
Like if all uneducated observations were spherical

thanks. i get these things mixed up some
Yeah, let’s leave it to Metal fans. They would maybe call it “nothing else matter”
