This is a very great caution, Alamo-Girl. I'm going to have to give that a lot of very serious thought.
Thank you so much for your observations and analysis! And also, as ever, your generous help and encouragement! Will dive into those papers you bumped me to now, to catch up on this mysterious "dark matter...!"
Thanks, A-G, with HUGS!
I thought you might be interested in the latest numbers on the subject of matter:
The WMAP team found that the Big Bang and Inflation theories continue to ring true. The contents of the Universe include 4% atoms (ordinary matter), 23% of an unknown type of dark matter, and 73% of a mysterious dark energy. The new measurements even shed light on the nature of the dark energy, which acts as a sort of an anti-gravity.
That's why the first article I linked to you about the possibility of an extra time dimension is stunning. If you are right and gravity propagates through an extra time dimension, it would explain why we cannot see dark energy in the laboratory but it is so prevalent in the "vacuum" of space. IOW, local gravity would appear in our dimension due to the presence of ordinary matter - but in the extra time dimension in the absence of ordinary matter.
That would bring the whole issue back to Einstein's marble of geometry, i.e. structure of space/time in multiple dimensions!!!
Just a thought to ponder, taking your speculation to another level...
