One of the most amazing phenomena of our universe is the black hole. Originally discovered by Einstein’s theory of General Relativity. It states that mass, when compacted to a certain point (defined in mathematical equations) will deform space-time to become a singularity – an entity that is so powerful, nothing can escape it. Not even light and consequently, space and time become one entity.
Einstein’s theory states that where there is mass, there is gravity and depending upon the size of the mass (e.g. a star), amount of gravity it contains can be determined, so mass is proportional to the amount of gravity and vise-verse. In other words, the more mass, the more gravity and subsequently, the more powerful the force it will have on objects nearby.
If an object comes too close a the mass where its gravitational pull is too strong for the object to pull away from it, it will be drawn into the mass. For example, if a comet moves too close to our sun, its gravitational pull will grab the comet and drag it towards the sun.
Adding one more variable to this rather straight forward concept is when a star, usually one that is much larger than our sun, reaches its end of life cycle, it will explode, and if it was big enough, or saying it another way, if its gravitational force was so large, then the entire star will collapse inward, it will eventually form a black hole.
This collapsible effect results in the fact that the mass of the star implodes by the star’s gravity to the point that all the star’s mass is drawn into a smaller and smaller space. As this mass builds, it becomes denser and as it keeps collapsing, the gravity becomes stronger. So strong that nothing can pass by it without bring drawn into it, including light.
Some black holes are considered to be the size of 10 million suns and it is theorized that every galaxy has a black hole at its center.
Let’s now explore in detail the theory of this singularity.
