 Is our universe the only one? If we discovered it all (probably we won't, at least not in at least the next google years), would that mean, we discovered everything, and there is nothing more?  We are not sure, however we can have our suspicions. At first people thought that everything there is, is the flat earth and sun with moon and stars circulating around it. They realised tat earth is in fact round, but they thought that it is in the cener of everything. Like before, they were wrong. Throguh time humanity started to realize that we are not in the cener, not in the only planetary system, and not in the only galaxy, but we are small, imperceptible piece of  thousands of trillions of galaxies. That leads us to a conclusion, that we are most likely not in the only universe. But if there are other universes, what are they like? We have just one anwser: Almost for sure, they are not like ours. They have diffrent laws of physics: gravity, light, movement, impact maybe even...

I published a post, about what is the Fermi paradox. There are many theories trying to solve it. Here are a few examples. Scientists claim that colonising the entire Milky Way by a single developed enough civilization should take around 40/50 mln years. Our galaxy has existed for billions of years, so we should  have already been visited by many extraterrestial species at this time.We might have been but that's unproven. However, for us sending anything, just to Earth's orbit consumes a lot of energy and expensive resources. Maybe other civilizations face the same problem. Even if they have technology that's able to send them to other planetary systems, many of them just don't have enough resources to do it within reasonable time. If that is true they could still send a signal to other parts of galaxy so why we still haven't picked up any? That leads us to another theory. Aliens can be way different than us. What if they see time differently? On Earth, for some smal...

Aliens almost for sure exist out there, due to the theory of probability calculated by scientists. It says that  probably there are millions of planets simmilar to Earth and tens of billions of others just in the Milky Way alone. Our galaxy consists of around 100 bln planets. If that is true, due to this calculation scientists say that there are probably hundreds of millions of planets containing life, among them millions of planets with intelligent species. That should give us the result of around 15 mln extraterrestial civilizations just in our galaxy. But if that is true....then where is everyone? We haven't even discovered simple life beyond Earth yet. Where are all these civilizations if there can be so many of them? Are we really alone? The anwser is: We don't know. This paradox is called The Fermi Paradox.  In fact, we can't solve this Paradox, although there are many possible explanations, some of them are unbelievable.  https://www.youtube.com/watch?v=mXi3K8LusZQ...
