#211 What is a dwarf galaxy?
I learned this today. A dwarf galaxy is a galaxy with 1000 to a few billion stars. Our galaxy, the Milky Way, has between 200 and 400 billion stars. Dwarf…

I learned this today. Jupiter’s Great Red Spot is a high-pressure region in the atmosphere that causes the largest anticyclonic storm in the Solar System. An anticyclonic storm is a…
I learned this today. There is no reason why the speed of light is 299,792,458 m/s. It just is. The speed of light is the top speed that matter or…
I learned this today. With the technology we have today a space elevator isn’t possible, but it could be possible in the not so distant future. The main idea for…
I learned this today. A wormhole is a hypothetical tunnel that would connect two separate points in space. Wormholes are hypothetical and have obviously never been discovered. They were first…
I learned this today. Dark matter is a hypothetical matter in space that doesn’t absorb, emit or reflect light, yet has gravity and keeps the universe together. It is theorized…
I learned this today. Light can’t escape from a black hole because of the curvature of space caused by gravity. In physics, gravity is the weakest of the four fundamental…
I learned this today. A Lagrange point is a point of equilibrium where the gravitational forces of two large objects balance out the centripetal force. A third object can remain…
I learned this today. The Kardashev scale describes five different levels of technological civilization, and we, as a species, haven’t even reached level 1. The Kardashev scale was, unsurprisingly enough,…
