Well then we better figure out where tf is the 80% of the matter in the universe hiding.
Comment on bro pls

When do we admit that maybe Dark Matter just doesn’t exist?

Easy. When scientists come up with a verifiable theory that explains observed gravitational effects in the universe that can’t be explained by general relativity, given visible matter.

I mean at this point, dark matter just seems like reaching at this point. Might as well be a neurologist searching for the human soul.
Gabu@lemmy.world 1 year ago
That’d be a valid comparison, if there were any evidence of a soul existing. The effects of matter, on the other hand, are clearly visible - or invisible, in the case of dark matter.
HawlSera@lemm.ee 1 year ago
Yes but at the same time we used to have all the evidence in the world indicate that planet Vulcan was just behind the sun, and then it turned out that no it wasn’t. If Dark Matter can’t be found no matter what experiment we do. Then maybe we are mistaken about its existence

While we haven’t detected dark matter in a lab, it isn’t on the same level as a metaphysical soul.
I’m not aware of any physical phenomena for which a soul is the best theory available.
Whereas the gravitational effects^1 observed cannot be explained by general relativity and detectable matter are, so far, best explained by dark matter.
1 includes: “formation and evolution of galaxies,[1] gravitational lensing,[2] observable universe’s current structure, mass position in galactic collisions,[3] motion of galaxies within galaxy clusters, and cosmic microwave background anisotropies.” - wikipedia

Just because something seemingly doesn’t interact with EM fields doesn’t mean it isn’t there, it’s just something that only really interacts with the rest of the universe on a gravitational level.

When you admit that night time doesn’t exist simply because you’re not there to observe it while you sleep. We know somethings there. We know there’s matter that isn’t adding up. We just don’t know what it is.
FastAndBulbous@lemmy.world 1 year ago
We don’t because we have experimental evidence for it’s existence.
agent_flounder@lemmy.world 1 year ago
I would argue that we have evidence for which the theory of dark matter and dark energy is a fairly suitable theory.
FastAndBulbous@lemmy.world 1 year ago
That’s all any theory in physics is. You don’t see an electron, you observe what it does.
agent_flounder@lemmy.world 1 year ago
Sure, yes, but my point was that we don’t have evidence specifically for the existence of dark matter.
We have evidence that is not explained by visible, detectable mass.
Dark matter is the current favored theory which happens to explain discrepancies between what is observed and what is expected.
But I don’t think we can logically conclude dark matter is the only explanation, which is what your original statement seems to imply. It is the best explanation that we have so far.
If we place objects on the dining table the night before and observed them lying on the floor the next morning, we can’t claim “we have evidence for sleepwalking residents.” There may be another theory that explains it, such as: the cat is knocking the things off the table. We need additional evidence to determine which theory fits or else come up with a new theory.
Hopefully I am making sense here lol

No we don’t

We have gravitational evidence. We can only ever infer the existence of anything. An example of this is we didn’t actually see the Higgs Boston we just deduced it’s existence from the cascade of interactions that happens when particles collide. Similarly we can deduce from the gravitational evidence that dark matter.
