But (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.
