The vast vast universe always contains the most unexpected things that people cannot imagine. From 14 billion years ago, it was filled with stellar explosions and immortal materials were created. Let’s learn about the interesting things of the universe when compared to the correlation on Earth..
1. If stretching the entire DNA in the human body, it would extend 54.7 billion km, meaning it will extend 6 times the distance from the Earth to Pluto and back.
2. Most ordinary matter has internal gaps. If you take the gaps between atoms in 7 billion people, the population of the entire earth, it will fit into a sugar cube.
3. Many of the atoms that make up your body are calcium in the bone and iron in the blood, formed from a certain star explosion in the universe billions of years ago.
4. Did you know that your body contains remnants of the Big Bang – the explosion that forms the universe. Most of the hydrogen atoms around you were formed by the Big Bang 13.7 billion years ago.
5. When you switch channels on TV, a small percentage of static electricity you see is the halo of the Big Bang at the dawn of the universe.
6. Although the speed of light is the fastest at approximately 300,000 km / s, the distance from the stars to the earth is too far, so it also takes a long time to reach your eyes. When we look at the sky, the images of the stars in the sky are their past.
7. On July 21, 1969 humans first set foot on the Moon. To date, footprints remain on the surface of the Moon and it has remained intact for millions of years because the satellite has no atmosphere, so there is no wind and water to erase the tracks.
8. The universe is very quiet. Because the universe is a vacuum, sound cannot travel in space. Therefore, in the space, even if you shout to the fullest, you cannot hear your sound.
9. If you attach two pieces of the same metal stick together in space, they will stick together forever. This cannot happen on Earth because the atmosphere has created an oxidized layer of metal that covers the pieces of metal.
10. One year in Venus is 224 Earth days, but one day on this planet is 243 Earth days long. Therefore, a day on Venus is longer than its one year.. In addition, Venus is also the only planet in the solar system to orbit itself in the opposite direction.
11. The Sun accounts for 99.86% of the total mass of the Solar System. It is so big that it could hold 1.3 million Earths inside. The mass of the Sun is 330,000 times the mass of the Earth.
12. There are about 3 powers of 23 stars in the universe, that is, number 3 with 23 “0” behind. There are more stars in the universe than the number of grains of sand on Earth. But the naked eye we can only see about 5000 stars in the night sky (optimal viewing conditions).
13. When a giant star explodes, its core becomes a neutron star. The neutron star is very dense matter, just a small spoon of its material heavier than Mount Everest. A typical neutron star has a mass of 1.35 to 2.1 times the mass of the Sun. The explosion causes the neutron star to spin around the axis at a rate of up to 600 revs per second
14. Normal objects that can be observed like stars and planets make up only 5% of the mass of the universe. The remaining 95% is made up of dark energy (68%) and dark matter (27%). That means up to 95% of the universe we don’t yet know.
