5 Greatest Mysteries About Universe

The Universe... The incredible scale difference between the small world we live in every day and the vastness of all time and space raises the question of whether we will ever be able to grasp the fullness of space. But that doesn't stop us from trying. In fact, pondering the great unknown must be one of the oldest hobbies in the human experience. This search led to people who mocked first religion, then philosophy, and then religion and philosophy.

  We may never understand the entire universe, but we can understand that it is complex enough to elude us.

  1. Extraterrestrial Intelligence

  Alien, Meat, Extraterrestrial, Space, Humanoid

  It's a really simple secret. Carl Sagan reminds us that if we exist, no matter how rare an intelligence the universe is, given how big the universe is, we must have many neighbors out there somewhere. Astrophysicist Frank Drake created an equation that helps us understand how much intelligent life there is in the universe and estimated that if only one out of a billion planets has intelligent life, then the number of planets with intelligence must still be more than 6 billion.

  In them. However, Enrico Fermi pointed out that if life is so common, it is virtually impossible that we have yet to detect any signs of other intelligent life in the universe. So here's the real mystery: What on earth makes no one want to play with us?

  2. Tunguska explosion

  On June 30, 1908 (or the 17th since then; the calendar has since been updated) at 7:17 a.m. (local time), something exploded in a wooded area in the Tunguska River valley in Siberia. Russia. Locals saw a bright blue object many miles away heading towards the area and it exploded with incredible force enough to register on instruments in England. Further investigation of the site showed that the trees had fallen radially from a central point, indicating some sort of airburst. To this day, scientists are not sure what it was, and generally speculate that it was a piece of a meteor or a comet. Why did it explode in the air? Why didn't we find any pieces? This mystery has kept UFO enthusiasts up at night ever since.

  3. Rare antimatter

  Matter and antimatter were theoretically created at the same time by the same event. When a normal baryon particle is created, an antiparticle of the same mass and opposite charge is also created. However, although we create antimatter in laboratories on Earth, we do not see it in the universe around us. No one knows what happened to all the antimatter that was supposed to be there…

  4. Consciousness

  What is the mind? Behaviorists say these are just conditioned responses. But it's hard to deny that our ability to reflect our own thoughts is something different and interesting. Is it just a side effect of how our brains work? If so, how long will it take for a computer to be self-aware and demand equal rights? How can one distinguish real consciousness from something designed to simulate it? There are so many questions, but there really won't be any answers until you can have a conversation with a robot or a ghost.

  1. Dark Matter / Dark Energy

  Current models of the universe and observations made by high-tech instruments indicate that there is much more matter in the universe than we actually see. In fact, we only perceive 4% of the things in the universe directly. The rest is invisible or "dark matter", we just don't know what it is. It is a type of energy that accompanies dark matter, such as dark matter, which we cannot directly perceive. Apparently there's more to it than dark matter. Various theories abound, but perhaps, as mentioned in #10 above, most of the universe simply eludes us.
