The most mysterious object of the world

BLACK HOLE
Black holes are one of the most mysterious things in the world. They are so mysterious that even Stephen Hawking and other scientist are not able to fully understand its properties. So let us understand that how a black hole forms and dies:

1)Formation of Black holes:- Black holes are formed by implosion(an inward supernova/explosion)of huge stars (at least 5 times more bigger than our sun which occupies approx 99% of weight of our solar system). The gravitational force which acts inward towards the core of the star is so high in such huge stars that the star's core collapses & the star began to shrink.
Finally a stage comes when a star whose size was even massive than sun is converted into a body whose size is in meters(Black holes) & its mass is concentrated to a point (Singularity).
* Just think for a moment that a star which was 5 times greater than sun have now all its mass in a point. Volume have become negligible(as compared to the initial volume of the star) but mass remains the same, now i think you can imagine that how much high its density is. Its density is so much high that even when light enters its gravitational field area(event horizon) cannot escape from its pull.

2) Death of a Black hole:- A Black hole's size increases when it engulfs any thing in space but decreases with time if nothing comes in its field area. Hence Black hole can only be destroyed when nothing comes in its area other wise it will keep on increasing.

Hawking solved one of the most imp. problem of scientists

 Hawking's Radiation Theory Confirmed As Black Holes Are Created In Lab Stephen Hawking's Radiation Theory Confirmed As Black Holes square measure Created In workplace 'Black holes' created in a very workplace make sure writer Hawking's radiation theory - and that they might win the scientist the laurels Hawking's theory could not be well-tried, because it did not relate effects of radiation Most believed not possible for data to cover whereas region shrunken Two separate teams of researchers have proof to keep a copy these claims These discoveries might facilitate win the scientist the laurels   Forty years past, physicist magnificently declared black holes evaporate and shrink as a result of they emit radiation. This alleged 'Hawking radiation' was a revolutionary theory, however thanks to the delicate nature of the escaping radiation, has been troublesome to prove. Now, 2 separate teams of researchers have discovered ...

Exsistence of worm holes!

How do Worm holes look like(if they exsisted) If Wormholes are literally planning to Work, they will ought to Look Weird. . Here's the most recent analysis on if wormholes square measure are literally planning to work, they have to seem weird. Here's the most recent analysis on if wormholes square measure doable. In a new, unreviewed paper, researchers counsel the conditions that would have created stable wormholes. By applying quantum concepts to plain gravity, the researchers were ready to satisfy the necessities to create a travelable hole. Their answer is for a pseudosphere rather than a sphere, creating the maths additional amenable. Could the primary stable wormholes be additional like ... real worms? The hole style that would eventually succeed is small and surprisingly formed, Iranian researchers say. No word on whether or not these wormholes can seem solely once a downfall. The theoretical hole, of any form or stability, is that the resu...
