I do not understand how a quark-antiquark is possible as when antimatter-matter pairs appear they immedietly explode, so how is it possible for mesons to form.

2 billion meters of mirror would be a major expenditure and would be a possibly an unecessary expense for a society when they could simply use cameras already in place.

If we (I am talking about the human race right now) could master that technology then we would have major connundrom as you could theoretically conduct experiments at a faster pace then normal without the need to use large amounts of computing power. However it would/could cause major problems becuase anybody with enough money or influence to get into an area that would allow to happen. I am forced to agree with Igge as the wikibook -- special relativity is a very heavy read but a very informing read. i would reccomend it to anyone who is interested in special relativity.
