Comment on Study: Dark matter does not exist and the universe is 27 billion years old
SkyeStarfall@lemmy.blahaj.zone 7 months agoWe can detect its gravitational influence, as it interacts via gravity. The issue being that gravity is a weak force, and so there’s a lot of room for speculation.
But there is a lot of evidence backing up dark matter existing. But it’s not definitive yet.

I get that but it still sounds woo-woo since we can’t directly detect it. I’m not naysaying since I realize it’s the best we have and I’m not smart enough to come up with anything better.

I mean, I guess it depends on what you mean by “directly detect”. We measure neutrinos by having photoreceptors in huge tanks of very pure water deep under old salt mines… which hardly seems more direct than looking at where galaxies and stars are moving and calculating the gravitational pull and noticing that something is missing…
