REFLECTION

This article is very attracted article for me! I think, this is a great discovery of a human being!

First, this discovery made that scientists could the figure of the first universe. This mean is that we can know how state about 13billions years ago. The light that was observed this time was about 0.5billions years later from universe was born. So, this time light is almost first figure of first universe. And then, some scientists have already study about first universe.

Second, I think that we can know why this universe was born. If this reason is known about this, we can know about universe more. And possibly, we will become that we can go out to outside the universe by to know about this. Because, I think we can know how to close, we can open the gate as the door of complex vault. But in fact, a famous cosmologist said that to go out to outside of this universe is very easy.

In concluding, this discovery is very big one step to know about universe. But also, universe has many mystery that we cannot discover.
