We know what 4% of the Universe is made of. But what about the rest?
There was a time, not so long ago, when science seemed to understand how the universe worked. Everything – us, the Earth, the stars and even exotic-sounding supernovae – was made of atoms which were all created at time-zero: the Big Bang. In between the atoms was nothing, a void: quite literally, 'space'.
But recently things have started to unravel. There is, it seems, a lot more to the universe than meets the eye. According to the best estimates, we only really know what about 4% of it is made of. But if only 4% is made of atoms, what about the rest? The rest is made of mysterious entities about which very little is understood, with equally mysterious names: dark matter and dark energy.

暗物质,宇宙诞生之初就已产生,甚至导致普通物质的诞生,它无处不在,无所不能,影响银河系的诞生,也许还影响人类的进化,它就是一个迷,【最新的研究成果可以观看{了解宇宙如何运行}第5季第8集暗物质之谜】,我们对它还知之甚少,我想也许可以利用暗物质湮灭进行宇宙航行呢,呵呵。。。
