About 10 years ago I sold an illustrated piece of poetic prose about our multiverse with some truthful yet humorous explanations* of our interaction with our relative universe parents and neighbors in other dimensions and how our universe began with two branes (parents) colliding and then giving birth to our new expanding space and matter. Some of this piece really was ahead of its time but there was no math to verify 11 dimensions so it was not cosmology proper, just a good introduction to the multiuniverse theory.

A notion I am entertaining now is that dark matter is indeed within its own dimension. Within that dimension gravity is a VERY powerful force in comparison to the weak way it interacts in our perceivable 4D universe.

How close is this dimension to ours? It is always and everywhere 10 to the minus 20 millimeters away. That is purdy durn close yet do consider that there are clumps of it that is far more dense than it is in our particular neighborhood. Should we (our solar system) pass through a thick strand of this dark matter the gravity could rearrange our planets and asteroid belts...again.

As our universe is continuing to accelerate in its expansion we are at the mercy of dark matter dimension/s as it pulls us with it. In our space gravity is one of the weakest forces there is but not in the dark universe. There, it is as strong as the strong electron magnetic force.

So I go out on a skinny limb and wonder if dark matter may form its own black holes and leave its own dimension over time while pulling on our dimesnsion les and less as it grows smaller and smaller. If it could then maybe our universe might slow its expansion and increase its longevity.

A sci fi fan might read about a race of advanced space doctors who undertake to expamnd the life of this universe dimension...complete with all the trade offs and repurcussions it might cause.


*(we are the child universe but we seldom call or see our parents etc.)

It will take physicists and modern day Jules Vernes alike to take the plunge into these new realms of understanding. Now I anxiously await the results of the biggest partical accelerator in the world to start up, without accidently making a mini black hole that could result in a class A supernova, to learn about which new questions we should be asking.




PS
There is a huge erupting gas nebula that apparently collided with an oxygen and hydrogen di sulfide rich galaxy millions of light years ago and is only now visible and "smellable" by spectrology to astronomers.

I hearby dub it the Spaw nebula.
