In the eighties of the last century I enjoyed the New Scientist; every week it was packed with English eccentrics expounding their own versions of Einstein's relativity theories. But later I stopped reading it, because it began to be full of gruesomeness - a change of editor perhaps.
This week, however, in a news-agent's odds-and-ends bin, I discovered an interesting number published a month ago. One of the articles therein has to do with "dark matter." It surprises me that scientists have been so surprised to discover that most of the universe consists of matter which does not emit light. Is that not what any scientist may discover simply by leaving his house after sunset? That the discovery of dark matter took a hundred years is a demonstration of a lack of imagination. So what will be the next discovery after non-light-emitting matter? Obviously it will be the discovery of objects that are not material at all. But that will take the main body of scientists at least another hundred years.
In fact the whole notion of "discovery" is misconceived. In a certain sense we already know everything we discover; did we not how could a discovery ever be recognized for what it is?
Usurped by. Yes kleines c I thought I had written "cloak" but see now that control of my finger was usurped by some sombre multitude. "Clock" is a definite improvement so I'll let it stand. What is the scientific view of this "invisibility cloak"? It has a bright future does it not? And out of interest, how far can you see into the future?
