I have a very limited understanding of any of it — but I think GraceG is on to something in her post up thread.
Could very well be. I have more confidence in that explanation than any pronouncements couched in absolute language by scientists being tasked (and paid) to prove its existence.
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.
There is definitely something. I was watching a show about galactic structures, superstructures, and strands that. It really does seem clear that there is an unknown something that forms a framework for our universe.
