Death is not the end, yet the beginning of something entirely afresh and majestic. In a similar trend, scientists argue that the celestial bodies give birth to new masses upon its death. There are several theories, scientists and researchers are studying, constantly to understand the nature and characteristics of these masses. So these are mysteries of Blackhole and Neutron Star.
Two of the most popular theories relate to Blackhole and Neutron Stars. Their origin, existence and a lot have been a constant conundrum in the world of science. No one can yet answer all the queries, but scientists have given a few plausible explanations. Some of them are here to feed your knowledge thirst.
There are billions of trillions of zillions of chemical reactions going on continuously in this universe. When the results or products of these reactions couldn’t coexist with each other, an explosion takes place. That existing mass dies, giving birth to million others. The new mass could become a neutron star, a black hole or even something like planet earth.
Existence of Stars
Let us take the sun from our solar system. Consider the outer layer of the sun, which is pulled inward by the gravitational pull from the central (core) part. Due to this pull, pressure is exerted and elements in the core are compressed together, reacting with each other. This reaction releases enormous energy which travels against the gravitational pull, trying to escape. Here, a balance needs to be maintained between these two as it stabilises against each other. When this balance will get disturbed, perhaps by exhaustion of hydrogen or helium gas, an implosion is inevitable.
The outer layer, discussed above is the hot plasma, that the stars are made of. The chemical reaction in the centre happens between hydrogen and helium elements. The energy from the reaction and the gravity acts against each other. Till the time they remain balanced, the star remains intact. When one of them exceeds the other, the composure gets disturbed and the star undergoes phases from helium, carbon, oxygen and finally to white dwarfs. In larger stars, owing to the imbalance, under intense pressure towards the core, carbon turns into neon, oxygen, silicon and lastly into iron mass.
This iron mass doesn’t indulge in any further reactions and gets squeezed under the weight of the entire star. This weight forces the electrons (negative) and protons (positive) to get fused together with neutrons. The pressure is so great that the mass of a huge star gets compressed into its millionth part. What happens next is called the Supernova explosion. The iron mass formed earlier explodes and leaves the resultant Neutron star.
Post the Supernova explosion, there are two possibilities. The first being, as discussed, the formation of a neutron star. However, if the star is quite massive in size, its mass collapses into a Blackhole. It is an event horizon, beyond which, practically no matter can escape. In its centre, there is a singularity, exact characteristics of which are not known. While being on the outer side of the black hole, the substance slows down and eventually disappears.
5 closest black holes are:
A few fun facts or Mysteries of Blackhole
- Although a human, if fell into a black hole, would die before reaching the singularity, they will get stretched like spaghetti before that.
- Black holes do not suck outer matter like vacuum cleaners. It merely takes in the matter that falls into its gravity.
- The Big Bang theory claims that Black holes eventually collapse and forms another mass.
- Miniature black holes are created after the Big Bang, which is lesser in size and denser in mass.
- Such theories are often interpreted and presented in fictional works, like that in the movie, “Interstellar”.
Difference between Blackhole and Neutron Star
There are a lot of similarities between Blackhole and Neutron stars. We just understood one of them: their origin. Nevertheless, differentiating the two cosmic products is not as easy. Since both of them have common properties, largely the magnitude could distinguish them.
Black holes are much larger in size than Neutron stars and thus, they can push the stars easily. Either of them could absorb the outer matter in itself and yet get incredibly dense. Though, only the latter is more palpable than the former. Neutron stars are hot in temperature, while the Black holes maintain a very low temperature.
Coming to the outer surfaces of these, Neutron stars are hard-surfaced, i.e, their outer texture is difficult to penetrate. In contrast to this, the Black holes do not display such property.
The dark matter in the black hole keeps shrinking. It shrinks till the point it bursts. On the other hand, the bright Neutron stars take the outer matter and become denser and denser, until it dies.
The Ultimate Battle
So far, we have established that the Blackhole and Neutron stars are unbelievably powerful and can engulf any matter. Still, the ultimate question comes, which of the two is stronger? Which of them is more powerful than the other? The answer to such questions can not be simply objective. There are lengthy theories and various arguments, assumptions, suggestions by various scholars in the field to resolve the issue.
In the simplest sense, it can be said that in a collision between a Blackhole and Neutron Star, there are majority chances in favour of the Blackhole to win the battle and survive post the collision. But, this is not necessary to happen always and often depends on the size of the two competing in the battle.
Overall, it can be said that Blackhole and Neutron stars are two celestial enigmas, existing in the universe since eternity. They share their origin but meet different ends. Both are the most extreme things that exist in the universe. No other object can stand any chance of mere survival against any of these. Such are the miracles of science, which could seem highly interesting and witheringly scary, all at the same time. Ongoing and upcoming researches and studies are yet to reveal much more about this truly incredible Universe. Explore the space. Thanks for Reading
