Do you ever wonder that portion of the outer space with immense darkness, shaped like a huge round object? It’s called a black hole. In truth, you cannot see black holes with your bare eyes but they exist in numbers in the outer space.

Just as you love discovering strange realities about the outer space, here are the top 10 most interesting facts about black holes.

Fact 1: Black holes and wormholes are different. A black hole is simply a dark star formed when supernova loses all its fuel and burst into its own weight. As it dies, it stops emitting light and appears like huge a dark spot in space. It is three-fold larger than the sun and has a very strong gravitational field. A wormhole is a theoretical opening in space that serves as shortcut to another dimension.

Fact 2: Black holes have borders known as “event horizons” also known as the point of no-return. While many people mistaken black holes with worm holes, objects lost after passing through the event horizon do not take shortcut to a new location. They are simply lost or destroyed because of the intense gravitation pull draping at its core, that even light could not escape it.

Fact 3: The gravitational pull in a black hole is too strong that it could destroy a moving star. Astronomers at Ohio University reports that a star wandering 650 million light years away towards Ursa Major where the “Big Dipper” is located was able to pass through a black hole, but a chunk of its materials was destroyed by the black hole’s extreme tidal force.

Fact 4: However a black hole may not be able to destroy a cockroach. Black hole theorist Kelly Holley-Bockelmann says that the size of a cockroach gives it a longer chance of enduring the gravitational pull compared to any other objects in space.

Fact 5: Black holes spin. When viewed through a telescopic instrument, a black hole looks like a stagnant funnel-shaped fissure in space. In truth, it has a spherical shape that rapidly spins sideways with a speed half of the speed of light. Its whirling motion results from a massive spinning supernova.

Fact 6: Black holes are not always black. They warp lights of passing objects causing them to bend and make the spinning surface of a black hole look colorful.

Fact 7: The distorted lights from extraterrestrial objects allow astronomers to see the black hole, using a high-powered telescope.

Fact 8: It was not Albert Einstein who discovered black holes. It was John Mitchell together with Pierre-Simon Laplace who first discovered the theory of dark stars in 1783. They called them “freeze stars.” According to both astronomers, when a star is at its final phase of gravitational collapse, the light is no longer able to escape it causing to die on its own. In 1916, Albert Einstein explained the effect of a black hole’s gravitational pull on lights through its theory of general relativity.

Fact 9: Black holes can be noisy. The outer space is an endless silent legroom. However, the spinning motion of black holes causes change in the speed of other objects nearby, which produces an earsplitting sound or strong jitters that can only be detected through radios.

Fact 10: We may be living in a black hole. One of the weirdest theories of modern astronomers is that our earth might be inside a black hole, or the entire universe is in a huge black hole itself. In fact the nearest black hole to earth lies at the center of the galaxy. It is called a micro quasar with a distance of 1, 600 light years away. That is equivalent to 43,280,000 years traveling to a destination.
