    also "dark" in Dark matter and energy doesn't refer to it being dark, but being "unknown"
    If dark matter exists, then it DOES exist "right here". But since we don't know what it is, we don't know how to detect it.

    I lean toward "dark matter" being real; I think it is the simplest explanation of the data that has already been mentioned in this thread. The main alternative to dark matter is MOND (modified Newtonian dynamics), but it is hard for the various MOND theories to explain everything that dark matter does (e.g. the bullet cluster).

    I lean toward it being a mistaken idea about the expansion of the universe, or some unknown flaw in our math on the topic. Much simpler explanation that some invisible mass that we can't measure in any way.

    I am saying it is used as one. Whether it is conclusive, can be actually debated.

    Has JohnMartin brought this one up in a non-locked thread? What was the answer?

    But as to its being used, I do frequent other Geocentrics sufficiently to know about what arguments they use.

    This thread is not about Geocentrism, so don't derail it.

    Looks like "modified gravity" may make "dark matter" unnecessary.

    Very interesting. I look forward to learning more about this.

    This is basically another version of MOND. I am skeptical that it can explain gravitational lensing as well as dark matter does. And it would require a new theory to explain why the force of gravity does not fall off as 1/r^2, or the gravitational potential as 1/r. This is a very tall order.

    and it looks like the mainstream fuddy duddies are agin' it! That is usually a clue that they are on the right track. Upending the status quo. Everyone mocks and say no, and then eats crow. Happens with every new revolution in science. Doesn't mean that this guy is correct, but whatever IS correct will be sure to upset the entrenched scientists with a stake in the old ideas.
