Is there a physicist in the house?

Jerome Fine replies: Ummmmm ... I think the problem, Fred, is that the English language was being used - perhaps that might be the reason why you ... I don't normally jump in on these "discussions", but this was one response I could not seem to resist. Actually, I probably did not understand the explanation any more than Fred did, however, I do realize that VERY small concentrations of energy / matter are being discussed - and that is what makes all the difference between what is ordinary and what takes place at a level that is (almost?) totally beyond normal human senses. As stated in this discussion, a lot of what is observed is not actually understood as to the reasons WHY! Perhaps some theories might explain some observations in a few centuries, but right now I seem to understand that even electricity can't actually be explained, only observed and measured. Part of the reason is that the universe is a VERY delicate balance. Change a few of the constants by even a small percentage and life as we observe it here on the Earth could not exist. Just one example is H2O. It is one of the few compounds which is lighter in the normal (or usual) frozen state than in the liquid state with which is is in contact. Ice bergs FLOAT!! I don't know or understand enough to provide other specific examples, let alone describe even a few of the states of frozen H2O. At the other end of the spectrum, the VERY (IMPOSSIBLY?) LARGE, other very interesting things (phenomenon) also occur. Black holes are just one example. Our universe is extremely interesting!
