![]() ![]() The valley created by a black hole gets steeper and steeper as you approach it from a distance. It's also why light can't escape a black hole: the sides of the valley are so steep that light isn't going fast enough to climb out. That's why, when you get close enough to any massive object, including a black hole, you fall towards it. Many examples include: Interstellar, Event Horizon, Star Trek, Battlestar Galactica, Treasure Island, Superman: The Animated Series, Transformers.3D illustration of the Earth and Sun on distorted spacetime. There are a multitude of black holes portrayals in science fiction. Black Holes Are Constantly Used in Science Fiction. Black Holes Are Only Dangerous if You Get Too Close.īlack holes are safe to observe from a lengthy distance, but not if you get too close, which also means that it’s unlikely for a black hole to consume an entire universe.ġ0. ![]() We don’t know if this event exists, since we don’t know too much about physics, but that also means that anything may be possible.ĩ. Scientists now believe that this black hole is about 20,000 light years away. V4647 Sagitarii was thought to be 1,600 light-years away, but is further away than expected. The Closest Black Hole is Probably Not 1,600 Light-Years Away. The First Black Hole Wasn’t Discovered Until X-Ray Astronomy was Used.Ĭygnus X-1 was the first black hole discovered in the 1960’s, and it’s 10 times more massive than the Sun.ħ. This is explained by Einstein’s Theory of General Relativity, which states that time is affected by how fast you are going when you’re at extreme speeds close to light.Ħ. The person who fell into the black hole’s time slows down, relative to the person watching. Say someone falls into a black hole and there’s an observer that witnesses this. There are also a variety of these all over the Milky Way.ģ) Supermassive Black Holes – These are the largest of black holes, being more than 1 million times more massive than the Sun. There are Three Categories of Black Holes.ġ) Primordial Black holes – These are the smallest of black holes and range from an atom’s size to a mountain’s mass.Ģ) Stellar Black Holes – These are the most common of black holes and they can be up to 20 times more massive than the Sun. The remainder of the core collapses, a spot overcome by density and without volume – a black hole.Ĥ. When the pressure from the nuclear reactions collapses, gravity overwhelms and collapses the star’s core, and the star’s other layers are thrown off into space, and this process is also known as a supernova. ![]() The death of large stars lead to black holes, because a star’s gravity will overwhelm the star’s natural pressure that it maintains to keep its shape. Our Milky Way Probably Has a Black Hole.īut, don’t be alarmed, Earth isn’t in danger! The major black hole that astronomists believe to be within our Milky Way is light years away from Earth.ģ. For example, a star that’s close enough to a black hole can be seen being ripped apart.Ģ. ![]() Analyzing the surrounding area of a black hole, we can see its effects upon its environment. What we can see, though, is the effects of a black hole. Now, here are 10 fun facts about black holes!Ī black hole is called a black hole because of it’s color, especially since light can’t escape. What exactly is a black hole? Put simply, a black hole is a spot in the universe where there is a large gravity pull. ![]()
