We are all inhabitants of this universe, within which we sit upon the Earth inside our solar system in the Milky Way galaxy. There are a vast number of things that scientists have discovered about our universe that you likely don’t realize. From the astounding to the confounding, here are 17 things that you probably didn’t know about our universe.
- Each year the moon moves 3.8 cm away from the Earth It’s true, the moon is actually slowly spinning away from Earth and in a few billions of years, it could actually cause the Earth to become very unstable
2. The Sun makes up 99% of the mass in the entire solar system
The sun is roughly 109 times the diameter of Earth and could hold over 1 million of our planets.
3. There are 10 billion trillion stars in the universe at minimum, In more scientific terms, this is more than 10 raised to the 22nd power stars.
4. About 275 million new stars are born each day
This equates out to about 100 billion each year.
5. It takes a photon about 170,000 years to travel from the core of the sun to the surface
This occurs as energy slowly radiates outward through the Sun’s radiation zone.
6. The center of our galaxy tastes like raspberries and smells like rum
Based on studies of the dust at the center of our galaxy, amino acids present suggest that this is how it might taste.
7. Earth’s rotation slows by about 17 milliseconds a century
This means that our days get longer by about 2 milliseconds every ten years.
8. The Earth is 93 million miles from the Sun
Driving non-stop at 60 mph, we would get there in 177 years. Although things might get a little hot before then.
9. There are mirrors on the moon that allow us to calculate its precise distance from Earth
These were placed there during the Apollo missions. We to this day shine lasers at them and monitor the moon’s distance given that we know the speed of light
10. The Milky Way rotates at about 250 kilometers per second and completes a revolution every 200 million years
We’re on a rotating sphere orbiting a star inside a rotation solar system inside a rotating galaxy inside an expanding universe. Trippy.
