 (This post contains all my knowledge about black holes that I have come to learn recently)  – Exoplanets 1.1 – What is an Exoplanet? Put simple, exoplanets are just planets in the universe that don’t orbit our sun. We believed that they existed for hundreds of years despite having no evidence or any detections, until eventually our technology became good enough to let us detect these mysterious little worlds. 1.2 – History into the discovery of exoplanets Back in the 1600’s there was an Italian philosopher named Giordano Bruno who was far ahead of his time. Bruno believed that the universe has no center, and that the stars in the sky are just like our sun, with their own set of planets and moons surrounding them. In fact, it was this very belief that had him tried for heresy by the Roman Inquisition as these facts went against the Catholic beliefs of the time. He was found guilty and burned at the stake. Perhaps the first believer in these wonderful worlds burnt at th...

(This post contains all my knowledge about black holes that I have come to learn recently) 1.0- What is a Black Hole? Blackholes are maybe the most elusive objects in the entire universe. They are extremely dense, massive objects that have such a strong gravitational attraction, not even light can escape their pull. Our galaxy alone could contain over 100 million individual black holes, but since they emit no light, they are extremely hard to find unless they are eating. 1.1 – How are Black Holes formed? Blackholes are formed when massive stars collapse under their own gravity at the end of their life cycle creating a singularity, a point of infinite density at the center of a blackhole. 1.2 – Sagittarius A* At the center of our own galaxy lies a supermassive blackholes named Sagittarius A*. This Blackhole has a mass of 4.3 million times more than our sun and is surrounded by a disc of gas and dust spiraling into its gravitational embrace. 1.3- Gravitational Waves of Black ...
