Ham, be sure to check out their 10 Most Convincing UFO Sightings Of All Time at the end of the
video. It spans approximately 150,000 light years in diameter, contains at least 100 billion
planets and at least 400 billion stars. This is the Milky Way in Numbers. The Milky Way
is the galaxy that is home to our solar system, but it is just one of an estimated 200 billion
galaxies in the observable universe. The oldest stars in the Milky Way are 13.4 billion years
old. This indicates that the galaxy formed shortly after the big bang, making it almost
as old as the universe itself. At the very center of the Milky Way is a super massive
black hole called Sagittarius A-star, which has a mass 4 million times that of the Sun.
90% of the Milky Way’s mass is dark matter, meaning that only 1/10th of the Milky Way
can be seen. The Milky Way is moving with another 100 galaxy groups around the center
of the universe at around 600 kilometers per second. It will collide with our nearest neighbor,
the Andromeda Galaxy, in about 5 billion years, and this event may cause two super massive
black holes to collide! If I were you, I’d start preparing! We hope you enjoyed this
look into space with AllTime Numbers.
