The Universe
There is nothing more paradoxical, thrilling, and surreal than the universe we live in. It's so out of the explanation, wild, and complex, that there is no need for additional fantasy or fiction over it. We just have to take a look around, try to comprehend the nature of even a small thing like a flower or a bug, let alone something like our solar system, and suddenly we enter into the endless rabbit hole with no definitive answers. Since the beginning of our civilization, we have always wondered about the meaning of life, the laws of nature and yet there is a new theory changing the old one, a new fact proving us wrong. It's like an infinite loop we are going through. Although, our understanding of the mechanisms of nature is progressing and from a pragmatical point of view we have advanced a lot, there are some philosophical questions that still leave us in numb bewilderment.
Here you can enjoy a short video of three of them and ponder over it.
