The Interstellar Travel

Black holes have always been a mystery to many. Many scientists have dedicated their lives for the study of black holes. Although till date, we still don’t have an actual picture of a Black hole; scientists are trying to get a closer look at it. And with advancements in the field of technology, soon we’ll be able to see an actual picture of a black hole. How is it possible? Let’s see. Event Horizon Telescope is a project which has been started to study the event horizon of the black hole -Sagittarius A* which is situated in our galaxy. It will capture the pictures of the event horizon and send it back to Earth.   Before going into detail of this project, first let’s see what an Event Horizon is. Event Horizon: Event horizon is a boundary in space-time, beyond which the events cannot affect the outside observer. Simply put, it is the boundary of no returns. It is the boundary of the black hole, beyond which events are not affected by the space time and once in this...

“Black holes are where God divided by zero” – Albert Einstein.  Black holes are giant black bodies in the outer space, which have baffled the minds of many! Many believe their existence as an enormous body that pulls everything in and destroys it and many other believe their existence as a place where time stops and freezes everything. But apart from these beliefs, there are real questions like: how black hole is formed? How it was discovered and what are the theories that explain the nature of the black hole. Black holes are formed when a star collapses upon itself. In short, a star causes a supernova and explodes to form a black hole. Simple enough, isn’t it? Now let’s get into the discovery of black hole and many theories surrounding it. BEGINNING OF BLACK HOLE THEORY:   The idea of Black hole was first put forth in the 18 th century by John Michell. He put forth this idea in a letter published in 1783-84. The calculations in the letter assumed that ...
