Okay are you all familiar with the “Rubber Sheet and heavy steel ball” model they always use to describe “how gravity works”....

You stretch out a rubber sheet and put several metal ball bearings on it and they create “dents” in it, much like planets do to space time.

One thing they forget to take in effect is the matter on the “other side” of the sheet.

Take the rubber sheet and stretch it over a kiddie pool filled with a non-compressable medium like say water.

Then put the steel balls in it and observer what happens...

They make the same dents but at a distance it causes the sheet to move upwards (negative energy), because of this upwards lifting of the sheet itself to compensate for the dents the “gravity” becomes stronger at certain closer distances (dark matter) than that of the old model.

Now put this 2-D model in 3 dimensions....

That is how Gravity works, I suspect there is an underlying “uncompressable” space time metric that lies “under” the normal fabric of space time.

I suspect you may be onto something, and I have also suspected that dark matter is just a crutch.

I’m impressed. Thank you.

There may very well be an anti gravity of sorts working on a cosmic scale. By rights the galaxies should be evenly spread across the universe but they aren't and aside from local groupings they should be outside the gravitational influence of each other. That should prevent them from forming up into galaxy clusters and strands.



Maybe its a weak force like gravity that is weaker and only shows its effects in cumulative forms. Maybe it compresses galaxies into the cosmic strands at the same time it drives the expansion of the universe.

That's the trouble I've always had with the 2-D model.

You really have to mentally visualize it in 3-D to see what's really going on.

I visualize it as a central point of gravity (mass) influencing a sphere of space surrounding it.
The 2-D visualization, always presented, is somewhat misleading.

They didn't forget, they decided to ignore it as inconvenient. Because you cannot use a two dimensional model to demonstrate the behavior of three dimensional objects in a three dimensional universe.

And let's not get into the ~12 dimensions of M theory.
