I would argue that Wikipedia is wrong or misguided. There is no serious debate about whether or not dark matter exists. I also think you’ve completely missed the point of my argument regarding the EM field just being only one way to detect the existence of things.

But it is visible, it’s visible in terms of gravitational effects. We can “see” the effects of dark matter. That is evidence specifically for dark matter, i.e. matter that is very hard or impossible to detect via the electromagnetic spectrum but is observable through gravity.

Dark matter is the explanation, the question is more what form does it take.

It just takes a bit of acknowledgement that actually the EM spectrum is not the only way to view the universe. In fact it’s just one of four (maybe five) fundamental forces. We’re just used to that being the default for seeing because it’s how we physically see. It’s an anthropocentric bias to say something doesn’t exist because we can’t view it via EM radiation despite the fact gravity is clearly showing it to us.

You could use your logic to argue against the existence of black holes. We don’t see them by definition but they are most certainly there.

You make the patents too easy to get and it fucks the little guy over as the big corps hoover up all the ideas. You make them difficult or impossible to get then that also benefits the big guys over the little guys as they will just steal people’s ideas and produce them for cheaper with their existing infrastructure which creates an even bigger monopoly.

There is a sweet spot that society is trying to reach. It’s imperfect like any system but it’s far far better than having no system.

You’ve not even considered that in order to get a patent granted you have to disclose your invention to the public which stops big corporations hoarding too many trade secrets.

All in all, the idea that patents shouldn’t exist benefits nobody except the large corporations. Say goodbye to start ups growing in size if that is the case.

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.

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 Boson 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 exists.

That’s all any theory in physics is. You don’t see an electron, you observe what it does.

It’s all fine calling patents bullshit until you start getting large corporations stealing technology from small and medium enterprises.

The way to ensure that large corporations and no small businesses can thrive have an even bigger monopoly is to get rid of the patent system.

Tired of this shit on Lemmy. Do your homework.

We don’t because we have experimental evidence for it’s existence.
