![]() ![]() A non rotating black hole’s horizon appears to be spherical on the surface with a radius which is similar to the Schwarzschild while a spinning black hole has a distorted horizon that makes the equator to swell due to its rotation (Parker 30). For example, incase the sun is substituted with a black hole that has a similar weight it subsequently affects its rotational behavior (Rau 23). Theoretically speaking, a sufficiently compressed mass will become a black hole.Ī black hole on the other hand is believed not to be a cosmic vacuum cleaner. Its surface is called the event horizon which happens to be its border. This in essence tells us where the name black hole came from. This is the main reason that explains why there is no information received or found from this region. Singularity is therefore an area in which the force of gravity happens to be stronger in such a manner that nothing can escape away from it including light. Its eventual collapse to a point of zero volume and an immeasurable density leads to a creation of singularity. A general theory that has been put forward suggests that the content found in a black hole is usually compressed to a point that it is usually called the singularity point (Luminet 295). Black holes will collapse on their own due to the fact that it has no outward forces that are opposing it. if a heavy stone falls on the ground it leaves behind a huge man hole. Therefore, it is argued that if a larger and massive star explodes, it might possibly leave behind a massive burned out stellar remnant e.g. This is to say that an object with a high gravitational field that has a high velocity is more likely to surpass the speed of light (Parker 25). This means that they can go into the future or the past years.īlack holes are simply said to be the evolutionary endpoints of stars that happen to be 10-15 times massive to the sun. Movies from Hollywood portray black holes as time physical entrances to tunnels that if one goes through, he can either move back or fourth in years. Several myths have been generated in many attempts to try and explain what a black hole is and Hollywood is at the forefront of it. This explains the origin of the name, Black hole. This implies that they are able to attract and pull anything including light at a very high speed. ![]() From far enough away, their gravitational effects are just like those of other objects of the same mass.Black holes are space zones in the universe that are dark in nature and possess natural forces of attraction that have a very high gravity. They don’t provide shortcuts between different points in space, or portals to other dimensions or universes.Ĭosmic vacuum cleaners. This effect, called gravitational lensing, can be used to find isolated black holes that are otherwise invisible. Massive objects like black holes can bend and distort light from more distant objects. Scientists can detect some of these by the ripples’ effect on detectors. When very massive objects accelerate through space, they create ripples in the fabric of space-time called gravitational waves. 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. Scientists primarily detect and study them based on how they affect their surroundings:īlack holes can be surrounded by rings of gas and dust, called accretion disks, that emit light across many wavelengths, including X-rays.Ī supermassive black hole’s intense gravity can cause stars to orbit around it in a particular way. Credit: NASA's Goddard Space Flight Center/Conceptual Image Labīlack holes don’t emit or reflect light, making them effectively invisible to telescopes. A bright jet of particles erupts from near the black hole, with another unseen on the opposite side. The black hole is surrounded by a bright accretion disk and a darker ring of gas and dust. This illustration shows the supermassive black hole at the center of a type of active galaxy called a blazar. ![]()
