What is the cause of gravity?

Question

Has anyone read the Cosmic Forces of Mu by James Churchward? Any interesting truths to be found there that might explain causes of gravity and the other 3 major forces of the universe? If there are 11 or 20 dimensions are we talking about physical dimensions? Or astral? Or something else? The mystics speak of many dimensions other than the 4 we know of the physical plane.

Answer 1

Haven't read it. I think the other dimensions are physical but we can see them. An awesome video that explains them is here: http://www.tenthdimension.com/medialinks.php

Answer 2

It is difficult to explain how to understand extra dimensions beyond the 4 we sense. The most honest thing to say is that the extra dimensions help in the description and in predicting behavior of phenomena. As such, they can be understood to be purely a construct of human thought. It may turn out that there is some physical evidence for extra dimensions, but these dimensions will turn out to be physical in a way we cannot easily perceive.

I have not read the book you mention. I do know that the extra dimensions are used to explain how the fundamental forces can be understood as being unified, but this description does nothing to explain the cause of gravity or the other forces.

Answer 3

I haven't read it, but I see my local library has it. I was planning to have a look at it until I read the reference below. Though he apparently did some real inventive and engineering work, that specific book is a work of fiction, which did influence some other, subsequent fiction.

Insight into the cause of gravity is more likely to come from serious academic efforts, such as quantum gravity, quantum loop gravity, superstring theory, and M-brane theory. The latter two require a minimum of 11 physical dimensions, exactly one of which is temporal, and the rest spatial. They are not mystical or astrological, they are mathematical. If any of the string/brane theories prove true, we will have a better idea about whether the dimensions are 'real' or merely useful mathematical constructs.

Answer 4

Gravity is a theory. You can't touch it or see it but it's effect on all manner of things is observable.

The interesting part about a theory is that it only has to proven wrong once to consign it to the trash can. It can be applied successfully many times but that dosen't constitute a proof. It remains a theory until it is proven wrong.
This theory is tested millions of times by applying the math to all manner of practical situations (eg rocketry) and it has passed the test every time. Gravity remains a theory only.

Presumably gravity has a cause but it is not understood to best of my knowledge.
