This is easy to explain. For Einstein's theory of gravitation you have the experimental evidence of every experiment every done, and against you have one guy with a half-baked argument.

Plus accusing the mainstream scientific community of "blindly and religiously believing in [...]" is a page taken directly from the Crackpot Index [1].

"They are suppressing my work!"

"They do not want you to read this!"

Etc.

That's a pretty fun index. If you removed the bias of accepting the current cosmological model as consensus and read it like it was submitted by a grad student how many points would the dark matter & dark energy model accrue? Is it logically consistent to propose a model that requires such a large adjustment by the inclusion of variables that have never been experimentally proven to exist? Does this model rest on the laurels and works of Albert Einstein? "10 points for each new term you invent and use without properly defining it." Do dark matter and dark energy not qualify here?

IANAP (physicist) but using this index it's hard not to imagine another place in the multiverse where this dark energy/matter cosmological model receives a high score on this rubric.

> every experiment ever done

But that is manifestly untrue. If every experiment confirmed Einstein we would not even be talking about dark matter.

> one guy with a half-baked argument

But that "one guy" happens to be an expert in the field. And his argument sounds fully baked to me.

[munchler]

Dark matter doesn't contradict general relativity, so it's entirely plausible that a) every experiment confirms Einstein, and yet b) we still need dark matter to explain some observations.

[potamic]

I don't believe we have yet managed to conduct an experiment to detect dark matter. We have observations that seem to contradict Einstein, but no experiment that concludes. I believe a couple of experiments are currently underway, exciting times.

[aranchelk]

There are other hypotheses competing with dark matter which have revised models of gravity, it’s not just one guy:

The theory of gravitation is not at question here, it is in fact the basis for proposing the existing of some yet-unseen matter to account for why the observed galaxies behave. Someone proposing that there is no such thing as the thing we have never observed is... a pretty "baked" argument.

I would like to toss my own idea into this discussion. This idea incorporates a mechanism that would explain why gravity might slightly deviate from Newtonian and/or GR in some circumstances.

This paper also adapts GR in such a way that it is consistent with galactic rotation rates, the anisotropies of the CMB, and cosmological expansion -- while showing that the simple operation of gravity is the cause of each of these phenomena.

Cyclic Gravity and Cosmology (CGC) predicts that there are discrete specific sizes allowable for macro-objects. The instability of Bennu and the fact that it behaves more like loosely held scree rather than a compact mass -- is an example of a mass that is not exactly at one of the discrete allowable sizes. Please also refer to the link I included wherein I uploaded a video simulation of the formation of a solar system using this type of force law. (This is in section 18 of the paper)

I would greatly appreciate any comments on this idea. Copies may be downloaded here:

Actually, the hard thing about dark matter is that the arguments for it and the arguments against it are both relatively compelling. No matter how this shakes out, we're going to have a very different view of the universe when we finally understand what is really happening.

[TillE]

There aren't really any satisfactory alternatives to dark matter. The question is what exactly is it, and how did it get there.

[citizenpaul]

>the arguments for it

We don't understand why our numbers don't add up so we made up a number to explain it is "compelling" to you?

Dark matter has always reeked of "ether" to me. I looked into some of the alt science on this a long time ago. There is a compelling case that our model of gravity is wrong. Fortunately gravity is such a weak force that at small ie solar system scales it doesn't matter. Which is why we can launch satellites around the system. However the failure shows at large scale like galaxies.

[TremendousJudge]

Dark matter has always smelled of phlogistons to me. It's this mystery substance that solves all of our problems, and doesn't make any predictions. I have no idea what a more accurate explanation for the observations would look like, but dark matter can't be it.
