Please let me know when dark matter shows up on the Periodic Table of the Elements and has a place on the table. The key idea about dark matter that I understand - without plenty of dark matter in the computer models simulating the origin of the universe after the Big Bang - the universe just expands and nothing forms
Exactly ! As far as our physics are concerned it is not there at all, and it does not have to be because we are but one universe among eternally billions of universes in which dark matter is the only constant. I have recently published two Science Fiction novels (Dark Matter Transit) which do not attempt to explain DM, except to say that it has no length, no width, depth and no mass. In other words it is immeasurable. There has, however, been a lot of theorising about the DM of late on the basis that there appears to be a unexplained mass near galaxies and this has been put down to DM being influenced by gravity. A simpler solution would probably be that the immense gravity of a galaxy attracts all manner of fine particles which are spread too thinly for optical instruments to discern but in total represent a considerable gravity in their own right. Fancifully, perhaps, I have appended the little ode below to one of the books
Ode To Dark Matter
I see it not, but I am aware,
I know that there is something there.
What is this thing that fills the void
twix you and I and the asteroids ?
It cannot be measured in feet or metre,
Nor even by mile of kilometre.
What is its’ use, I wonder why
It lurks unseen in a clear blue sky ?
Is it the flux that binds-all-together,
from Saturn’s rings to Scottish heather ?
Is this the place where spirits thrive.
The place we go when we are not alive ?
It is the unknown between the stars,
from way out there and Earth and Mars.
It is the path, as we evolve,
that beckons us on and on to solve.
What future then awaits mankind ?
If only we were not so blind.
Are our differences just so great
that world war three we contemplate ?
Sidetrack not-then our ultimate role
for irreligious or political goal.
If we can survive as the human race
Then wonders galore await us in space
