Hey @zyx066, thank you for taking into the world of science, it is very controversial world between scientists there are some who have different theories about the existence and reality and when they explain everything sounds sensible. That is why I love science, I love those people who live their subject who are teacher in their hearts who have their theories and really happy to explain and not to change your mind and make you think differently. It is difficult subject the human life, cosmos and of course many explainable things around us that makes me even more interested in science to see and to find what is it. I believe we just need to help each other to understand and probably to solve the problems together but not every on his own. But on other side I want that some of the things still remain unexplained :)
