In 1940, Britain had retreated back to their island fortress after being throttled in mainland Europe by invading Nazis. They would hide behind the sea and hope that their navy and air force could stop the possible German invasion of their island.
As the Battle of Britain raged on, the German and British air forces went head to head. Something strange happened, the Germans pulled of[sic] a series of highly effective night bombing raids. It's strange because night bombing was incredibly ineffective for the most part.
[...] This German bombing was much more effective than what the British could do at night. As a matter of fact, it was more accurate than what typical bombing could do in the day time.

Such as? It's worth keeping in mind, for example, that MOND, the primary rival to dark matter, is of the same sort of theory. It attempts to explain observation without having any other support for the theory than this discrepancy. At least, with dark matter theory one knows that there is some dark matter, just not enough known dark matter at present to explain things.

Such as for over a century the only evidence for dark matter is that GR predictions the wrong thing.
Try pushing that when your friends and family are getting blown up over and over as you are "surprised" over and over at every new observation. Meanwhile MOND predicts the right thing. You will either start working on finding an explanation for why MOND works or get executed/assassinated by pissed off people.

Which is pretty good evidence when you think about it. They also have gravity lensing and actual observation of dark matter.

khallow, I do kind of like your posts. Please prep just a tiny bit for a grand minimum at least scenario.

How about wide binaries: dark matter predicts they should not rotate amongst themselves and should 'fly apart'. Meanwhile, QI eliminates the need for dark matter completely as well as solving why wide binaries exist.
Neither dark matter NOR Mond can solve wide binaries...unless of course they come up with ANOTHER 'newly imagined' property for dark matter.

And? Have we observed these for thousands of years to determine that they indeed don't fly apart (that is, aren't binary systems)? Rather we observed them for a short time and concluded that it must have always been that way. And that's the basic problem. Just because two stars are relatively near one another with similar velocities doesn't make them a binary system. We know of scenarios where this can happen, such as throwing a third star out of a three star system or several stars being created in a interstellar dust cloud.
Or the observations and our suppositions are in error. The key problem is that this is supposedly a subtle effect. Hence, it is precisely where wishful thinking and error in measure most strongly can manifest.

Have we observed ANYTHING for thousands of years? TRULY measured, calculated, observed? No.
That is what models are for.
"Hence, it is precisely where wishful thinking and error in measure most strongly can manifest."
YES! Dark matter is an error of wishful thinking: SAVE GR at ALL costs... except it is wrong and wide binaries prove it.

Unfortunately, that doesn't rule out models like dark matter because you are supposing the would-be evidence against such based on a model that may be wrong.
