Spinning seems to be the typical active state in all cosmic bodies in our universe. Our Earth spins. All planets spin. The center of our existence the Sun spins. The Solar System itself spins. This spinning motion can’t just be a coincidence. Scientists attempt to explain why does everything in the universe spin.
Around four and a half billion years ago, our Solar System had just begun to form amid clouds of helium and hydrogen. When these gases of varying densities stirred around space, a triggering event like a supernova potentially caused these gases to merge and coalesce. As the gravity of these converging bodies increased, they began pulling in all entities around them leading to spin in the counterclockwise direction. Curiously, the spin was in the same direction for all bodies.
This spin triggers a kind of “tossed pizza dough” effect with a ball in the middle and everything else surrounding it expanding outward in a disc, a common shape found all over the universe, attributed to the laws of physics.
Eventually, all these spinning elements collide to form larger and larger bodies that ultimately form planets, moons, etc., while maintaining the angular momentum as the spin continues due to inertia. This is the phenomena that cause the spin and causes everything to follow the same kind of spin. This movement is now slowing down but at such a slow rate that humans cannot consciously detect it.
This video from DNews explains the unending circular paths that everything in the universe seems to follow.
It is noteworthy that not all entities spin the same way. Venus is a notable exception in our own solar system, spinning clockwise. Astronomers aren’t quite sure and have proposed two possibilities. The first speculates that Venus somehow flipped upside down while the other suggests that somehow the planet gradually stopped spinning counterclockwise, paused and started spinning clockwise.
The other exception to the Solar System’s counterclockwise spin club is Uranus, which probably got knocked onto its side to now spin differently than all the other planets in the solar system.
In spite of these exceptions, everything from small asteroids to entire galaxies in the universe moves and spins some clockwise, others counterclockwise. We now know that forces of gravity, momentum, and inertia ensure that bodies big and small act upon each other, causing everything to move and spin.
