Our Universe is simply incredibly huge in size, and even if at least its approximate dimensions are once established, the human brain will still not be able to accept it, which is why every time scientists have new facts about this amazing outer space.
This time, experts provided seven facts about the Universe that people did not even know about:
1. We and everything around us was created from stars. When the universe was first born, there were some elements that formed the basis for the formation of a star, after which elements such as gold and iron appeared. At the same time, the human body contains a huge amount of elements from space, also gold.
2. The stars in the sky are echoes of the past. What we see in the night sky is only light that travels to Earth from a distant distance.
3. There are more than ten billion trillion stars in the Universe, while there is a large number of controversies among scientists on this topic, but many adhere to this figure.
4. We ourselves can be aliens. Some experts are of the opinion that simple microbes and bacteria, which after a huge amount of time became developed creatures, could get to Earth with meteorites.
5. Some people think that there are several universes.
6. Black holes can die. Stephen Hogin stated that if there is no "food" for her, then she simply disappears.

7. The universe is constantly getting wider. Until 1920, scientists talked about the fact that the universe was static, but after Edwin Hubble determined that it was expanding. In 1998, space telescope observations helped to see this process.
