• Black Holes 3 Star Hole Light

    Black holes are objects so dense that not even light can escape their gravity, and since nothing can travel faster than light, nothing can escape from inside a black hole. Loosely speaking, a black hole is a region of space that has so much mass concentrated in it that there is no way for a nearby object to escape its gravitational pull. Since our best theory of gravity at the moment is Einstein's general theory of relativity, we have to delve into some results of this theory to understand black...

    Black Holes black hole is the velocity necessary to take one away from one's own gravitational force. For example, the escape velocity of earth is equal to 11 km / s . anything that wants to escape earth's gravitational force or pull must go at least 11 km / s , no matter what the thing is. The escape velocity of an object depends on how compact it is; that is, the ratio of its mass to radius. A black hole is an object so compact that, close to it, even the speed of light is not fast enough to e...

    A black hole is an object with a concentration of mass great enough that the force of gravity prevents anything from escaping from it except through quantum tunneling behavior. The gravitational field is so strong that the escape velocity near it exceeds the speed of light. This implies that nothing, not even light, can escape its gravity, hence the word 'black.' The term 'black hole' is widespread, even though it does not refer to a hole in the usual sense, but rather a region of space from whi...
  • The Big Bang Theory Of Origin Universe
    1,412 words
    The "Big Bang" theory of the origin of the universe is a controversial yet widely accepted theory in the creation of the universe to it's present form. Dating back in history, the groundwork of famous scientists and their theories helped to develop the Big Bang theory to what is stands as today. Special note goes to that of Friedmann, Hubble and Einstein who all played major roles in the establishment of this theory and are all included in this essay. Other points that constitute this essay incl...
