The paper linked in the summary is essentially a rehash of this written in 2008:

This article essentially states that the far field gravitational effects of distant galaxies are not negligible. This is the essential meat of the idea.
From the article linked in the summary:
"In the literature, there are several papers which illustrate different ways in which the distribution of matter can be estimated, starting for example from the measured distribution of luminosity of the galaxies. We take instead the simpler path which consists in assuming a functional form for [local gravitational potential], with a minimal number of parameters and then trying to determine these parameters by a best fit with the observed rotation curves."
This part really bugs me. Why does the author completely ignore the luminosity distribution of the test galaxies. At the very least this means that all the pretty graphs you see when scrolling through the pdf are misleading.
"It is not easy, but who said it should be?"
I say It should be.
You might call me a whiner and complainer. I call myself someone with dignity and self respect.
This is why America is screwed. This country [usa] is filled with simpletons like parent that have no self respect. They say at least its not as bad as the third world shitholes. Well I say it could be a lot better too. We could have a country with universal healthcare, more vacation time, more job security and higher employment rate. This isn't some utopian ideal It happens in the socialist countries of Europe.
For Christ sake we put a man on the moon and the only point of pride you hear is: "[At least] I'm not melting solder off trashed PCBs in China."
The reason that your not melting solder in a shanty town is not because of the grace of the business elites allowed it to be so. It is because in the past labor organized and demanded better working conditions, weekends and an 8 hour work day.
Factorials were someone's attempt to make math LOOK exciting.
