  The Earth, our home planet in the Universe contains a wide variety of life with a huge complexity.It is the home of creatures in the deep oceans, the birds which roam across the sky, animals livings in forests and the insects living beneath the surface of Earth. Earth is the only known planet that can sustain life.Nowhere else life has been found yet.This variety of life on Earth have been made possible by various factors. Without these life on Earth could not have been possible. We will discuss them here. Effects Of Distance From Sun   The Earth lives in the habitable zone from the Sun, just far enough so that liquid water, the "universal solvent," can exist to create the chemicals of life. If the Earth were farther from the Sun, it might become like Mars, a "frozen desert," where temperatures have created a harsh, barren surface where water and even carbon dioxide are often frozen Solid. Beneath the surface of Mars one finds a permanent layer of frozen wat

  Black holes are among the most strange and mysterious objects in the Universe.These strange and mysterious objects are found in the center of almost all the Galaxies. Let's know about black holes in detail. What Is A Black Hole?   A black hole is the remnant of an old star, which dies by collapsing on itself due to gravity.The main part of the black hole is its singularity. A black hole's all mass is concentrated in a single point in space with zero volume and has infinite density. This part of black hole is known as singularity. This make the black holes the objects with most extreme and immense gravity.  Artistic Illustration Of A Black Hole Event Horizon   If you look at the black hole, you will be seeing at the event horizon. Event horizon is the boundary of the black hole. Once you have crossed the event horizon, there is no way out. The gravity is so strong that even light can't escape from it. The closer you get to the event horizon, stronger the gravi
