Dark Matter: Is a Revolution Coming to Physics?
scitechdaily.com ^ | JULY 15, 2022

Newton’s Theory of Gravity explains most large-scale events fairly well. ... However, the theory is not foolproof. Einstein’s theories of general and special relativity, for example, explained data that Newton’s theory couldn’t. Scientists still use Newton’s theory because it works in the overwhelming majority of cases and has much simpler equations.

Dark matter was proposed as a way to reconcile Newtonian physics with the data. But what if, instead of reconciliation, a modified theory is needed.... Mordehai Milgrom...developed a theory of gravity (called Modified Newtonian Dynamics or “Mond” for short) in 1982 that postulates gravity functions differently when it becomes very weak, such as at the edge of disk galaxies.

His theory does not simply explain the behaviors of galaxies; it predicts them. The problem with theories is that they can explain just about anything. ...One way to separate good theories from bad ones is to see which theory makes better predictions.

Recent analysis of Mond shows that it makes significantly better predictions than standard dark matter models. What that means is that, while dark matter can explain the behavior of galaxies quite well, it has little predictive power and is, at least on this front, an inferior theory.

Only more data and debate will be able to settle the score on dark matter and Mond. However, Mond coming to be accepted as the best explanation would shatter decades of scientific consensus and make one of the more mysterious features of the universe much more normal. A modified theory may not be as sexy as dark, unseen forces, but it may just have the advantage of being better science.

2. The laws of gravity change when we get to big structures like galaxies.

I've wondered about that myself. What if the laws of physics... ALL of them... vary based on the location you are at? What if Planck's value is different based on where you are in the universe? What if the Boltzmann constant varies? What if the rest mass of a proton changes, as your location changes?

Everyone knows you here laz. I was expecting one of your classic responses.

Though I see a lot of true conservatives that doesn't realize all this fake science we see today seems to have started with the fraud Einstein.

He wasn't completely alone.
Warren De la Rue started the miss conception that the Sun is a gas from this paper which has more holes in his theory then Swiss cheese. From this paper on the myth that the Sun is a gas was born.

What Is Thinking?
Thinking isn't saying what you think is right. Thinking is questioning what you think is right.

Interesting video. However, what I would come back with, to this Professor of Cognition, it is far less that we cannot perceive reality as it is, and far more that there are additional dimensions that exist that we CANNOT perceive, and THAT is the disconnect.
