Black Holes
What is a black hole Well, it’s difficult to answer this question, since the terms we normally use to describe a scientific phenomenon are inadequate here, Astronomers and scientists think that a black hole is a region of space (not a thing) into which matter has fallen and from which nothing can escape—not even light. So we can’t see a black hole. A black hole exerts (施加) a strong gravitational (重力的) pull and yet it has no matter. It is only space—or so we think. How can this happen
The theory is that some stars explode when their density increases to a particular point; they "collapse" and sometimes a supernova (超新星) occurs. The collapse of a star may produce a "White Dwarf (白矮星) "or a "neutron star"—a star whose matter is so dense that it continually shrinks by the force of its own gravity. But if the star is very large this process of shrinking may be so intense that a black hole re

[简答题] Stumped Rawalpindi
He has a normal head, but nestling between his massive shoulders it seems small. He is Shoaib Akhtar, "the Rawalpindi Express", the fastest recorded bowler of a cricket ball in history. And right now, before a small but baying crowd at the Rawalpindi Cricket Ground, he is steaming towards this correspondent. From 22 yards, Mr. Akhtar launches into the weirdly beautiful contortion that fast bowlers perform to hurl a six-ounce lump of cork and leather at up to 100mph. Half a second later, the ball demolishes the stumps.
For over two centuries, cricket has been played according to a largely unwritten code of honour for the practical reason that its laws are too complicated for officials to enforce to the reality. But technology has been rewriting the old etiquette. And according to some recent research, one of cricket’’s most basic laws is untenable, and now the game is in turmoil.
According to law 24. 3, bowlers may not str
