Stephen Hawking’s Theory Was Right. New Study Confirms Black Holes Do Not Shrink Over Time



In the black hole area theorem that he proposed in 1971, Hawking had suggested that it was impossible for a black hole to decreases in size over a period of time.

Outer space is filled with mysteries and while researchers have come a long way in their efforts to know more about the universe beyond the earth, there is still a lot to explore. One such topic of mystery that has always fascinated and  intrigued scientists and enthusiasts is the existence of black hole in the universe. The large region in the space that don't even allow light to pass through it has the gravitational pull that can pull anything inside if  it comes around its range even our milky way galaxy reportedly has the presence of  black hole that makes it research it even more important. One of the most celebrated physicist  in history Stephen Hawking had conducted various research in his career in a bid to understand outer space and black holes in the black hole area theorem that he proposed in 1971, Hawking had  suggested that is impossible to black hole to decreases in size over a period of time. This theorem was derived from Albert Einstein's theory of relativity defining gravitational waves and black holes. It fascinated many physicists around the world and became the base for several researchers. Now a a recent theory proposed by researchers from the Massachusetts institute of of technology has validated this theorem of Hawking. According to Livescience, the team of researchers led by astrophysicist Maximiliano used the data of gravitational waves released because of two small black holes merging into one to reach their conclusion. This gravitational waves were observed using the advanced laser interferometer gravitational waves observatory (LIGO) and divided into segments:  before and ud after the merger. The team then used this before and after measurements to calculate the surface area the black hole in each segment and it showed that the entire surface area of the  Madrid area vas higher than the sum of the two smaller black holes.
Talking about the findings, the researchers added that their findings confirm Hawking's area theorem with more than 95% level of confidence.

Stephen Hawking's theory about black holes may have been proven right.

  Turns out, black holes exert pressure on all space surrounding them. Hawking had predicted that black holes emit radiation in 1974, implying that the objects have temperature. In addition, Hawking claimed that black holes slowly shrink over time if no accumulation of gases (accretion) takes place.   Scientists from the University of Sussex - Professor Xavier Calmet and Folkert Kuipers published their findings in Physical Review D. The researchers were probing the event horizon (a black hole's boundary) of a black hole when they made the startling discovery.  They were looking an entropy at the event horizon of the black hole, which is essentially the chaos embedded into any physical object and its progression from calm to mayhem.  While reading the calculations, the scientists kept running into an additional figure which they couldn't explain. It took them months to figure out that it was actually caused by pressure around the black hole.   This pres...

Facebook Page roles explained

What are the different types of roles for Page managers and who should be assigned which role? Image credits:  https://www.facebook.com/shiva1196/ 1. Admin The admin has the most authority and access of all the Page manager roles. An  admin can manage and assign all other Page roles and settings, so for security purposes, it’s vital that businesses strictly limit who has this role. An admin can also do anything any other role can do, including:      •Edit the page and add apps      •Create and delete posts      • Send messages via the Page      • Respond to and delete comments and               posts        to the Page       • Remove and ban people from the Page      •Create ads      •View Page Insights (analytics about the           Page)      •See who published as the ...

Web results Water vapour detected on huge Jupiter moon Ganymede for 1st time

Astronomers have uncovered the first evidence of water vapour in the atmosphere of Jupiter's moon Ganymede using Hubble space telescope.   NASAs Hubble Telescope reveals first evidence for water vapour in Jupiters moon Ganymede. According to the study published in the journal Nature Astronomy on Monday, the water vapour forms when ice from the moon's surface turns from solid to gas. Previous studies have offered circumstantial evidence that Ganymede,  contains more water than all of Earth's oceans, NASA said. However, temperatures there are so cold that water on the surface is frozen solid, according to the US space agency. Ganymede's ocean would reside roughly 160 kilometres below the crust, therefore, the water vapour would not represent the evaporation of this ocean.  Astronomers re-examined Hubble observations from the last two decades to find this evidence of water vapour. In 1998, Hubble's Space Telescope Imaging Spectrograph took the first ultraviolet (UV) im...
