![]() Many examples include: Interstellar, Event Horizon, Star Trek, Battlestar Galactica, Treasure Island, Superman: The Animated Series, Transformers. 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. The answer is something like the newly discovered black hole-star binary system Gaia BH1, which contains the closest stellar-mass black hole to Earth ever discovered and a star orbiting it. 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 Milky Way’s black hole is about 4 million times the Sun’s mass, putting it in the middle of the pack. They range in mass from 100,000 to billions of times the mass of the Sun, far too massive to be born from a single star. The remainder of the core collapses, a spot overcome by density and without volume – a black hole.Ĥ. Supermassive Black Holes are the monsters of the universe, living at the centers of nearly every galaxy. 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. Astronomers tracked the orbits of several stars near the center of the Milky Way to prove it houses a supermassive black hole, a discovery that won the 2020 Nobel Prize. 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. The gravity is so strong because matter (the mass) has been squeezed into a tiny space.What exactly is a black hole? Put simply, a black hole is a spot in the universe where there is a large gravity pull. What is a Black Hole?Ī black hole is a dense, compact object whose gravitational pull is so strong that – within a certain distance of it – nothing can escape, not even light.īlack holes are thought to result from the collapse of very massive stars at the ends of their evolution. The black hole is outlined by emission from hot gas swirling around it under the influence of strong gravity near its event horizon. (There is a supermassive black hole at the center of our galaxy - the Milky Way.) Using the Event Horizon Telescope, scientists obtained an image of the black hole at the center of the galaxy M87. The short linear feature near the center of the image is a jet produced by the black hole. This image was captured by FORS2 on ESO's Very Large Telescope. The supermassive black hole imaged by the EHT is located in the center of the elliptical galaxy M87, located about 55 million light years from Earth.
