THE BLACK HOLE

 

A region is an object with such powerful gravity that nothing can shake it, including light.

The black hole's mass is concentrated during a point of just about infinite density.

this is nothing but singularity. At the singularity, gravity is almost infinitely strong.
it crushes normal space-time out of existence. As the distance from the singularity increases, its gravitational influence reduce.

At a particular distance, which depends on the singularity's mass, the speed needed to flee from the region equals the speed of sunshine.

This distance marks the black hole 'horizon', which is like its surface.

Anything that passes through the surface is trapped inside the black hole. Black holes are available several varieties, counting on mass.

black holes are formed due to the collapse of large stars at the end of their life cycle.

Does OUR SUN BECOME A BLACK HOLE?

no, why means read the following data carefully.


Our Sun is really too small to finish up as a region. our sun does not contain enough matter to exert that
kind of gravitational force on itself. if the sun becomes a black hole, it has to be more than 10 times greater mass.

THE EYE OF THE HUMAN

the human eye is the sense organ in the body to see and identify the objects. the cornea is a layer of the eye that protects eye from the dust and it acts as a protective membrane. behind the cornea, a humorous liquid is filled in a space. the iris contains a pupil in it, iris allows the light to pupil.iris is a muscular diaphragm. the pupil is a hole.it catches the light and does not reflect back.it is in black color. the lens is the backward covered portion to form the image from the retina. NOTE 1: the distance between the lens and retina is about 2.5 cm. due to the deficiency of vitamin A in our body, these symptoms may cause to eye:  night blindness, cornea failure. the retina contains the 125 million receptors called rods and cones which receives the light signal data from the eye and sends it to the brain through 1 million optic nerves.   NOTE 2: the lenses are; concave,convex,bi concave,bi convex,plano concave,plano convex, concavo-convex. HUMAN EYE SIGHTS: there are ...

SATELLITE

Hello all,  today I explained the satellites. study carefully. satellite is nothing but an object that revolves around the planet in a curved path. satellites are two types: natural satellites(the moon is a satellite because which revolves around the earth) artificial satellites(human-made) coming to the topic of artificial satellites; artificial satellites are made by the human and launched by the human through the rockets into the orbit of the planet. the satellite launching involves two steps: the satellite has to be taken into the desired altitude. pushed out from the spacecraft at the right velocity to begin and maintain it's orbit. the satellite launch vehicle moves straight only for a few seconds. A satellite launch vehicle is a multistage rocket, consists of a smaller booster rocket for boosting. boosters give the rocket initial thrust during the launch and carry the vehicle rarely part of the flight. when the fuel completed in the boosters they fall away from the rocket ot...
