BLACKHOLE- The Mysterious Region in space

What is blackhole      

Blackhole are some of the strangest and most fascinating objects found in outer space.  A  Blackhole  is  a region in  space  whose  gravitational  force  is  so  intense  that   nothing  can   escape   from it pulls not  even   light   of   electromagnetic   radiation.

Birth  of  Blackhole

Commonly a  Blackhole is produced by certain dying stars.  In the normal life of the star,  there is a  constant tug of war between gravity pulling in and pressure pushing out.  Nuclear reactions in the core of the star produce enough energy and pressure to push outward.   For most of a  star’s life,  gravity and pressure balance each other exactly or so the star is stable.

BLACKHOLE

However,  when a star runs out of nuclear fuel,  gravity gets the upper hand for the material in the core of the star,  the greater the force of gravity that compresses the material,  collapsing it under its own weight.

       When a very massive star exhausts its nuclear fuel it explodes as a  supernova. The other parts of the star are expelled violently collapses under its own weight.

      Its core remaining after the supernova is very massive (more than 2.5 times the mass of the sun), no know repulsive force inside a star can push back hard enough to prevent gravity from completely collapsing the core into a Blackhole.

Type of a Blackhole:

Depending upon their mass, Blackholes are of 3 types

  1. Stellar-mass Blackholes.
  2. Supermassive Blackholes.
  3. Intermediate Blackholes.

  1.Steller Blackhole

This type of Blackhole forms when a massive star collapses, Blagkholes formed by the collapse of individual stars are relatively small, by incredibly deeeeeense. Such as object pack 3 times or more the mass of the sun into a city-size range. This leads to a crazy amount of gravitational force pulling on objects around it. Black holes consume the galaxy around them, growing in size.

2. Supper massive Blackholes:

Supermassive black holes are millions or even billions of times as the sun but have radios similar to that sun. Such Black holes are thought to lie at the center of every galaxy including the milk way. Scientists don’t know exactly how supermassive Blsckholes from but it’s likely that they are the by-product of galaxy formation. Because of their location in the centers of galaxies close to many tightly packed stars&gas clouds, supermassive Blackholes continue to grow on a steady diet of matter.

3. Intermediate Blackholes:

          Scientists once thought Blackholes came is only small and large sizes, but recent research has revealed the possibility for the existence of midsize or intermediate Blackholes. Such bodies could form when stars in a cluster collide in a chain reaction. Several of this forming in the same region could eventually fall together in the center of a galaxy and create a supper massive Blackholes.

Structure of Blackhole:

In fact, we don’t really know what the inside of a Blackhole is like. Describing the characteristics of the structure of a Blackhole still remains one of the challenges of modern relativistic astrophysics. However, the scientists are able to define some terms related to Blackhole from which we know the structure of the Blackhole. Thing is.

Schwarzschild Radius: -It is the radius at which the escape velocity equals the speed of light.

Event  Horizon: The surface of the sphere of radius equal for the Schwarzschild radius is called the event horizon. The event horizon is considered the surface of the black hole. The light emitted from beyond the event horizon can never reach the outside observer.

Singularity: At the center of the blackhole Singularity, that is, the region where the current laws of physics break down because the circumstances are so extreme. Singularity contains all the mass of the black hole, so it has infinite density

What happen when you Fail into Blackhole?

               If you were falling towards a black hole, most of the time you would simply fill weightless just as floating in a most peculiar way in the intermediate space station. Suppose you were falling feet first towards a black hole. As you get closer your feet would feel a stronger force than your head. These differences in forces are called Tidal Forces. Because of the tidal forces, it would feel as  if you are being

stretched head to toe, While your side would feel like they are being pushed inward. Eventually the rip you apart. This effect of tidal stretching is known as spaghettification.

Interesting Facts About Blackhole:

     1)-A massive star collapsing upon it self.

-Physical laws cease to be valid at its core.

-Blackholes distort space time,

-Objects appear to freeze near a blackhole.

-A person falling into a blackhole would be spagettified.

-gravitational pull same as other objects of same mass.

-Worm holes appear similar to blackhole.

-Blackholes eventually evaporate over time.

-A massive blackhole lies at the centre of our milkyway galaxy

Conclusion:

Blackholes are not theoretical(as they once were) but are a reality. Most of the aspects of black holes seen bad or threatening when first looked at, but it is possible they can be very beneficial to us in the future if we could gain access to one. Time travel, which is not impossible, can be accessible to using blackholes, although it might not be very beneficial it we don’t know how to travel correctly. Finally, the fuel they could Provide us with enough energy to fuel s entire society is also very beneficial.
