I know the Dark Matter Theory is very successful at explaining lots of phenomenons of cosmological physics. Nevertheless, it always reminds me of the Aether Theory.
- irrational 8y agoYou say that like space isn't full of Aether. Are you an Aether-denier?
- Assossa 8y agoHopefully SpaceX will start selling bottled a aether soon
- tzahola 8y agoLet’s hope they won’t: https://en.m.wikipedia.org/wiki/Ether_addiction https://en.m.wikipedia.org/wiki/Ether_addiction

- Filligree 8y agoThink of it this way: The laws of physics don't form a complete (fully connected) graph. Not every force (edge) affects every particle (vertex). Electrons and photons (obviously) affect each other, electrons and protons do the same (through the electromagnetic field, for example), but photons and neutrinos do not. Why should we assume that the overall graph has only a single connected component?
- tzahola 8y agoBut (the hypothetical) dark matter does interact with regular matter through gravity, so your graph is connected. The existence of 100% non-interacting particles is by definition non-falsifiable, therefore scientifically irrelevant.
- dogma1138 8y agoDark matter may be just normal matter that we can’t see because it’s too cold, WIMPs are not the only candidate for dark matter, if anything they are the weakest one currently since we’ve been finding more and more brown dwarfs and even massive ones.
- perl4ever 8y agoI think the conventional explanation is that there are way too few lensing observations for normal matter to be anywhere near enough. You might read a news article that says there is 30% or 10 times more regular matter than we thought, but it's such a small baseline it doesn't make much difference to the big picture.
- nonbel 8y agoAether, or epicycles? Its more like epicycles in my opinion because it supposedly forms "spheroids" wherever the models need it.
- dogma1138 8y agoThere isn’t one dark matter theory there are many candidates none of them are exactly implausible or impossible. We can’t account for the mass of the universe so we are looking for it. There are two options either there is mass that we cannot detect through non-gravitational related observations or that we don’t understand gravity on a macro level which also puts relativity at odds. MOND was pretty much killed last year and it’s now completely off the books so modifying Newtonian gravity to fit in our understanding of the universe won’t work, which leaves dark matter which is again a place holder name for one or more types of matter that are very hard to observe. It can be wimps or it can be that there are a lot more brown dwarfs, rogue planets, and other bodily objects that we can’t see.
- Avshalom 8y agoI don't really follow astrophysics anymore was there anything specific last year that happened? (not that various mond's were ever particularly viable)
- dogma1138 8y agoGravitational waves specifically from the colliding neutron stars which were observed in “real time” in 2017 which arrived at the same time as the light emitted from the collision pretty much killed it.
