How Long Does It Take To Make A Black Hole?

calendar 28 September 2022

Hmm! It may not take a year or two to form a massive black hole. Going for the recent dates the search for black homes started in 2017. Most the black holes are born after a huge star explodes into a supernova. It is usually the force of gravity of a huge start that balances its radiations, the energy inside the stars that radiates light. But when the fuel of a star is burnt out, gravity in space quickly takes over and phew! The star collapses exceeding the speed of light. The collapse happens in an instant resulting in a decrease in the volume and the concentration of the gravity becomes so strong that nothing, no particle or even electromagnetic light can escape from it. Scary enough! Isn't it?

Till 2016 the scientists detected gravitational waves, then in late 2016 scientists confirmed the first black hole merger. Blackholes are stellar-mass when massive stars collapse at the end of their life cycle, growing by absorbing the mass from surroundings. They may then form Supermassive black holes of millions of solar masses, existing in most galaxies.

Considering the size of black holes in the universe are believed roughly a billion times the mass of our sun, surrounded by disks of falling matter shining that can be detected from immense stretches of space and time. These giants existed even before our solar system existed.

Let's Read About The Brief Structure Of A Black Hole:

The structure of a black hole is calculated using Albert Einstein's general theory of relativity. The event horizon, the object's "surface," hides the singularity, which is the nucleus of a black hole. Even light rays cannot get over the event horizon because the escape velocity (i.e., the velocity required for matter to escape from a cosmic object's gravitational field) surpasses the speed of light. The three "layers" of a black hole are the outer and inner event horizons, as well as the singularity. To identify black holes, scientists use the radiation that is produced as dust and gas is drawn into them. Students studying astronomy may seek science assignments help to them read further about the structure of a black hole.

Is It Possible For A Black Hole To "Eat" An Entire Galaxy?

That's quite a scary right!! We are also part of the Milky Way though only a minuscule as compared to other heavenly bodies. But astronomers and physicists studying the universe reveal that there is a black hole at the centre of our Milky Way. It is an impressive supermassive black hole with more than 4.1 million times that of the sun, in the direction Sagittarius constellation and is just 26,000 light-years away from us. So it is quite a distance from our solar system.

So what is the eating-up part of the black hole leading us? With the discovery of supermassive black holes in our Milky Way, scientists also discovered that in the heart of all galaxies are black holes. And these supermassive black holes may turn into what is known as 'Quasars'. These are the intensely bright objects giving off more energy than their galaxy. They are just big, massive black holes that are actively gobbling up so much material around them that it creates an accretion disk around them. They eliminate an immense gravitational force that is detected from an immense distance. Moreover, even if the supermassive black hole of our Milky Way turns into a quasar, our solar system will not be affected because of the distance between the centre of the Milky Way and our solar system. Even though we won't ever get to see it. As it may take some millions of years.

How Do Scientists Calculate The Mass Of A Supermassive Black Hole?

Astronomers calculate the mass of a black hole in many ways. Well, it does not include the conventional weighing tools or units. Of course, they are meaningless when t comes to weighing a black hole that may convert into a quasar down the lane. So, the simplest way is by doing it in a binary system. The objects in the binary system are two stars, a star and a neutron star, or a star and a black hole, etc following Kepler's law of motion, which allows the scientists to calculate the mass based on the speeds of the objects and size of their orbit. So the reason why astronomers employ the binary system to calculate the mass of a black hole is that it is not possible to accurately calculate the mass of a lone stellar-mass black hole created by the death of a single star. The reason is obvious that astronomers have observed a link between the mass of a supermassive black hole and the mass of the spheroidal components or the stars around it. This allowed the scientist to measure the milky way's supermassive black hole its mass of 4.4 million solar masses.

Ever Wondered About How Many Types Of Black Holes Are There?

Reading about astronomy is as interesting and intriguing and when it comes to black holes the information and interest never cease to end. Astronomers have discovered three different forms of black holes so far: stellar black holes, supermassive black holes, and intermediate black holes.

  • Stellar black holes: these are formed when a star burns exhausting its fuel, the object may collapse into itself giving rise to a new core that will become a neutron star or a white dwarf. However, when a big star collapses, it continues to compress to create a stellar black hole, producing an incredibly dense environment consuming dust and gas from surrounding galaxies that keeps its size growing.

  • Supermassive Black Holes: Scientists aren't certain how they form. there is a possibility that several tiny black holes that merge may have resulted in a supermassive black hole. Or it may be the case that a cluster of stellar black holes may be formed together giving rise to the supermassive black hole. Another assumption states that they could arise from large clusters of dark matter. Till now the largest black hole discovered is quasar TON 618. It possesses 66 billion solar masses.

  • Intermediate black holes: scientists have discovered intermediate black holes (IMBHS), which may eventually collapse together in the centre of a galaxy and create a supermassive black hole. Some researchers suggest that IMBHs may exist in dwarf galaxies or very small galaxies. Students who may find this information too lengthy or inadequate may seek help from assignment help and clear all their doubts and write a top-notch assignment on astronomy.

Bottom line: all galaxies typically have supermassive black holes at their heart. These black holes have a monstrous size ranging from a million or billion light-years in diameter being some billion times larger than our sun.
