Wandering 你好像沒有解釋,也好像又添加了更多的題目....
我那個物理系大三的兒子說他們學校沒教這些東西,因為是屬於hypothetical的subject.

下面的解說,我想我可以瞭解 - http://curious.astro.cornell.edu/question.php?number=361

What is dark matter?

Dark matter is the term astronomers use for the matter that they detect in the universe which cannot be seen.

What I mean by this is that although when you look through a telescope nothing appears to be there, the way that the visible matter moves indicates that there must be more mass present.

It is currently thought that about 10% of the matter in the universe is visible, the rest is something we don't understand.

"the rest is something we don't understand"

Yes, we only realize things we can see, hear, smell, touch or calculate by our own mean. Why doing the 'mapping'-- more concrete, or real for us to recognize. Is it possible not that simple? Even the explanation(人類物理學)is light bending, indicating invisible matters there.
Is our limit self-imposed.

Probably just 豆腐鍋吃太飽了,胡言一番.
Never mind, let's get out of this unknown darkness, 好好過地球生活吧.
