I've glanced through the whole thread with interest. In fact, Robert, Merrell did try to discuss your claims, right from the outset, by challenging the validity of some of your evidence. After all, the value of your speculations cannot be assessed until the evidence on which they're founded is assessed. But instead of defending your position and your claims, you simply handwaved the challenging evidence away. And then complained that nobody wanted to discuss your claims.
Well, I'd like to discuss your claim about the circulatory system. In the OP, you say "The smallest blood vessels (capillaries), make up 80 percent of the length of our circulatory system. This means blood must find its way through 128,000 km of capillaries (or travel a distance equivalent to three times around earth) with every circulation. Yet the diameter of capillaries is 8 microns — or one sixth of a human hair."
You are explicitly envisioning the circulatory system as one long thin tube - 128,000 km long by 8 microns in diameter - through which all the blood must be pushed with every circulation. That isn't how it works. The system starts out with a single thick vessel which branches eventually into a complex mesh of up to 10 billion capillaries, each about 600 microns in length, each of which is carrying blood cells in single file. The cumulative length of all the capillaries in the system means nothing, because only a minute fraction of the blood is following each possible path. The critical distance is how far each blood cell has to travel in each circumnavigation of the system.
We can work that out easily. It's estimated that a single red blood cell will travel about 480 km during its life expectancy of four months, equivalent to roughly 170,000 circuits of the system. 480km/170,000 circuits works out to 2.82 m/circuit, which is a VERY far cry from 128,000 km. I don't think the heart needs a jump start from the universe to handle that.
