We have just talked about the discovery of the farthest star in the universe. Many of you raised interesting questions:
Here are answers to four questions inspired by the discovery of the farthest star in the universe:
00:00 Introduction
01:46 How do we know if a faraway star is still alive or not?
05:58 Can we ever see "far" enough to "see" the Big Bang?
10:44 How do we know that the light from a star or a galaxy has been traveling for 13 billion years?
19:44 Is there any use of learning about such far away stars and galaxies?
