The notion is that each time a subatomic particle can one of several things, it actually does all them, splitting the universe into multiple copies which differ only in that one micro-event.

The universe splits, splits again, and ramifies into an astonishing tree of alternative realities, a quintillion times a second.

We have built actual Gravity Wave detectors, perhaps the first of which was constructed by Dr. Robert Forward, now a full-time science fiction author. We believe that gravity has caused the existence of "Black Holes", which I tend to lump into this category.

For that time in fan history, it was an impressive effort. There have been some recent reports of purported antigravity in the laboratory, including Avon, ] a fine description of tales in which animals speak, think, or act human. Dolittle" stories are so captivatingly charming and yet realistic that they make us forget that talking animals are Fantasy.

Some such tales are designed to show how humans fit into a world that contains many more species of beings, all deserving our compassion.
