Like the boundaries on earth, humanity has always looked at the sky in awe as it seemed limitless in its ever-expanding horizon. Among all the cosmos discovered and discovered every day, there is one object that still eludes scientists: the black hole. Albert Einstein, and all the brilliant scientists who followed his, helped design and create a part of the universe that is crucial to understanding existence. The perimeters of a black hole have been a big topic that has been discussed and observed to the point where it finally becomes clear in relation to objects around it or similar to it. The physics of the existence of black holes is still unclear because it shows properties that support Einstein's theory and quantum mechanics, but at the same time breaks them both. In 1915, Albert Einstein had proposed his theory of general relativity to the Prussian Academy of Sciences in Berlin. It took him three years to finally establish the equations for his theories, but he still has to go out into the field and test them. To do this, he needed a total solar eclipse, where the sun's pull on spacetime would still be affective but its brightness would not block the light of the stars behind it. Sir Arthur Eddington, an English astronomer and proponent of general relativity, had led an exploration on Principe Island, just off the coast of West Africa. It's easy to predict when the solar eclipse will occur, the problem is making sure you're in the right place at the right time, and that the weather is in your favor. May 29, 1919 was the day the eclipse was scheduled to occur, so from there the team set up the equipment and hoped for the best. Just as the moon began to touch the edge of the sun, the clouds began to thicken, but just before totality there was a pause. If...... middle of paper ......No black holes'ExtremeTech." ExtremeTech.
