是那个P1:the matter visual in the universe只占了5%,剩下的[E1]都是暗物质(dark matter)。
P2:what particles form the black object in the universe? It cannot be made by neutrons and protons as they are too small. Neither [E2]can it be made by Neutrino, which is a too light weighted particle. Experiment [E3]indicated the movement of the Neutrino is very fast, so it cannot form clumps and thereby very sluggish.
P3:Based on the experiment, the makeup should have the following features to fit dark matter: cold, massive, sluggish and stable. Such matters haven’t been found in the cosmos. People build a standard model to study the particles. It can be proved by theoretical approaches. The model is named as “symmetrical sth” (forgot the name).
P4:[E4]Talk about this model. This model find a particle, named as Neutrinal[E5], which has similar properties as Neutrino, but [E6]Neutrinal is more stable and no interaction with electronic magnify诶。才发现不是文章啊?反正基本的意思和考题基本都差不多的~看了这个定位很快 |
