- How Information Can Escape From A Black Hole?
Every black hole conceals a secret — the quantum remains of the star from which it formed, say a group of scientists, who also predict that these stars can later emerge once the black hole evaporates. The researchers call these objects "Planck...
- What Is Black Hole?
Black holes are some of the strangest and most fascinating objects found in outer space. They are objects of extreme density, with such strong gravitational attraction that even light cannot escape from their grasp if it comes near enough. Albert Einstein...
- Why Should We Wear White Clothes In Summer?
Generally we prefer to wear white t-shirts or white shirts . You may have studied about black body in your school or college level.I had learnt that black body is a good absorber of heat and radiation and a perfect black body can absorb all the radiations...
- History Of The Black Hole Theory
A black hole in space has gravitational force so strong that nothing can escape from it, not even light. Hence no one can see a black hole astronomers are convinced they exist. John Michell, a British geologist and astronomer, designed the experiment...

The prototype of this most popular of all teas was developed over a hundred years ago by the Scottish Tea Master Drysdale in Edinburgh using black Indian and China teas to create a strong brew to drink with milk. By the 1700s, it become indoctrinated...

Amazing Facts About Black Holes:
- If you fell into a black hole, theory has long suggested that gravity would stretch you out like spaghetti, though your death would come before you reached singularity. But a 2012 study in Nature suggests that quantum effects would cause the event horizon to act much like a wall of fire, instantly burning anyone to death.
- Black holes do not "suck." Suction is caused by pulling something into a vacuum, which the massive black hole definitely is not. Instead, objects fall into them.
- The first object considered to be a black hole is Cygnus X-1. Rockets carrying Geiger counters discovered eight new X-ray sources. In 1971, scientists detected radio emissions coming from Cygnus X-1, and a massive hidden companion was found and identified as a black hole.
- Cygnus X-1 was the subject of a 1974 friendly wager between Stephen Hawking and a fellow physicist Kip Thorne, with Hawking betting that the source was not a black hole. In 1990, he conceded defeat.
- Miniature black holes may have formed immediately after the Big Bang. Rapidly expanding space may have squeezed some regions into tiny, dense black holes less massive than the sun.
- If a star passes too close to a black hole, it can be torn apart.
- Astronomers estimate there are anywhere from 10 million to a billion stellar black holes, with masses roughly thrice that of the sun, in the Milky Way.
- The interesting relationship between string theory and black holes gives rise to more types of massive giants than found under conventional classical mechanics.
- Black holes remain terrific fodder for science fiction books and movies. Check out the science behind the movie "Interstellar," which relied heavily on theoretical physicist Kip Thorne to bring real science to the Hollywood feature. In fact, work with the special effects of the blockbuster lead to an improvement in the scientific understanding of how distant stars might appear when seen near a fast-spinning black hole.
