Space is a canvas in which the continuity of the painting is infinite, but only a small part of the canvas is visible. On July 20, 1969, Neil Armstrong became the first man to step on the moon. It’s been 38 years and only a very small fraction of the painting has been finished. We’ve come a long way in discoveries abstract concepts that are present in space; one of these concepts are black holes. Black holes are very fascinating and complex. They are one of the wonders of space. Black holes occur when a star burns through its remaining fuel causing it to collapse on itself. At this point, matter is being squeezed into a tiny space causing the gravity to be extremely intense that not even light can escape, hence the name black hole. Though …show more content…

This is the Ergosphere. Then, The disk composed of stellar material that is spiraling towards that black hole is called the Acceleration Disk. Thirdly, we have the Event Horizon, this is the point of no return. Any object, even light, that is within this radius cannot escape the gravitational pull of the black hole. Finally, we have the Singularity, this is the area of the black hole where the mass of the black hole has been compressed down to nearly zero volume. This results in the singularity having zero size, almost infinite density, and with finite mass, which creates an enormous gravitational …show more content…

Einstein’s Theory of Relativity is composed of two core principles - The Equivalence principle and Curved Spacetime principle. The Equivalence principle states that gravitational acceleration is indistinguishable from other forms of acceleration. For example, “a student in a closed room could not tell the difference between experiencing the gravitational pull of the earth at the earth's surface and being in a rocketship in space accelerating with a = 9.8 m/s2.” (University of California, San Diego Center for Astrophysics & Space Science) The Curved Spacetime principle states that matter curves space. In this view, gravity is not a force but a curvature in the fabric in space; in which objects follow that curvature that was created. The Curved Spacetime principle deals more with blacks holes. We cannot detect the curvatures directly but more indirectly using the binary pulsar system 1913+16. When a black hole is formed, the gravitational pull is so powerful that it results in the creation of a curve in the space
