In order to understand the matter, we must first realize our place in the universe. We live on planet Earth, and our planet revolves with other planets around a star we call the sun. Our sun is one of billions of stars in a galaxy called the Milky Way, and the Milky Way is one of billions of galaxies in the universe.
Our Sun is located in one of the spiral arms of the Milky Way Galaxy and is located in an arm called the Orion-Swan. The sun rotates with the spiral arm around the center of the galaxy, completing one revolution every about 250 million years. This is the galactic year.
Now, the old galactic year ends, and a new year begins, because the Sun, along with the Earth and the other planets, once again finds itself at the same point where it was 250 million years ago, that is, the solar system has made a complete revolution around the center of our galaxy.
Scientists cannot determine the exact date, day, year or century when the full cycle was or will be completed. We only know that the event is about to happen, and it could be on January 14, very likely. Therefore, Earthlings can exchange congratulations on the occasion of a Happy Galactic New Year.
If you measure the Earth’s history in galactic years, it is actually 18 galactic years old, which is the amount of time it has been since its formation.
In honor of this historic event, NASA researcher Jessie Christiansen shot an animated video. It showed our path between the stars, and the “historical landmarks” that the Earth passes through.
Dinosaurs appeared at the beginning of the last galactic year. It peaked in May, June and July, at a time when the Sun and Earth were on the other side of the Milky Way. Until October, the dinosaurs had no fears, until a giant asteroid arrived and fell 66 million years ago into the Gulf of Mexico, killing the dinosaurs and making room for mammals. Then humans multiplied by the end of December.
We live on Earth for “two weeks” or even less.
