About the farthest part of the distant universe.
Landing on the moon and traveling to Mars ... Maybe everyone has once had the idea of "I want to go to space someday!" Some may say, "I've never confided to anyone, but I was really worried about the end of the universe ...".
In this Giz Asks, we will discuss simple questions such as where is the "edge of the universe", what is there, what happens when we reach the end of the universe, etc. in cosmology and physics. I asked an expert.
After all, the keyword is the big bang. When I think about the end of the universe, what is worrisome is beyond the "observable universe." It's all the more interesting because it's a world that no one knows and has never seen, but is there a way for us to know the answer in the first place? Whether or not the universe has an edge = I run into the big theme of whether the universe is finite or infinite. When thinking far beyond the universe, we must not forget the relationship with time.
1. The end of the universe = the limit of observation

3. The end of the universe = something that can be seen in the oldest light
