Stephen Hawking
has produced a "mind-bending" new theory that argues black holes do not
actually exist — at least not in the way we currently perceive them.
Instead, in his paper, Information Preservation and Weather Forecasting
for Black Holes, Hawking proposes that black holes can exist without
"event horizons" , the invisible cover believed to surround every black
hole. During a previous lecture, "Into the Black Hole" , Hawkins
described an event horizon
as the boundary of a black hole, "where gravity is just strong enough
to drag light back, and prevent it escaping" . "Falling through the
event horizon, is a bit like going over Niagara Falls in a canoe" , he
said. "If you are above the falls, you can get away if you paddle fast
enough, but once you are over the edge, you are lost. There's no way
back.
"As you get nearer the falls, the current gets faster. This means it pulls harder on the front of the canoe, than the back. There's a danger that the canoe will be pulled apart. It is the same with black holes."
But now, Hawking is proposing "apparent horizons" could exist instead, which would only hold light and information temporarily before releasing them back into space in "garbled form" , Nature has reported.
The internationally-renowned theoretical physicist suggests that quantum mechanics and general relativity remain intact, but black holes do not have an event horizon to catch fire.
His work attempts to address the "black-hole firewall paradox" first discovered by theoretical physicist Joseph Polchinski and his colleagues almost two years ago, when Polchinski and his team began investigating what would happen to an astronaut who fell into a black hole.
They hypothesised that instead of being gradually ripped apart by gravitational forces, the event horizon would be transformed into a "highly energetic region" , and anyone who fell in would hit a wall of fire and burn to death in an instant — violating Albert Einstein's theory of relativity.
In his paper, Hawking writes: "The absence of event horizons means that there are no black holes — in the sense of regimes from which light can't escape to infinity."
He told Nature jour nal: "There is no escape from a black hole in classical theory, but quantum theory, however, "enables energy and information to escape from a black hole."
Don Page, a physicist and expert on black holes at the University of Alberta in Edmonton, Canada told Nature that "the picture Hawking gives sounds pretty reasonable" .
"You could say that it is radical to propose there's no event horizon" , he said. "But these are highly quantum conditions, and there's ambiguity about what space-time even is, let alone whether there is a definite region that can be marked as an event horizon."

ISSAC NEWTON SAID :-
"I do not know what I may appear to the world, but to myself I seem to
have been only like a boy playing on the sea-shore, and diverting myself
in now and then finding a smoother pebble or a prettier shell than
ordinary, whilst the great ocean of truth lay all undiscovered before
me."

Scientists rule out existence of 'sixth sense'
The
study found that people could reliably sense when a change had
occurred, even when they could not see exactly what had changed.
MELBOURNE: Sixth sense
dismissed! The common belief that a sixth sense - also known as
extrasensory perception - exists, may be false, a new study has claimed.
The study found that people could reliably sense when a change had occurred, even when they could not see exactly what had changed.
For example, a person might notice a general change in someone's appearance but not be able to identify that the person had had a haircut.
Lead researcher Dr Piers Howe from the Melbourne School of Psychological Sciences said the research is the first to show in a scientific study that people can reliably sense changes that they cannot visually identify.
"There is a common belief that observers can experience changes directly with their mind, without needing to rely on the traditional physical senses such as vision, hearing, taste, smell and touch to identify it. This alleged ability is sometimes referred to as a sixth sense or ESP.
"We were able to show that while observers could reliably sense changes that they could not visually identify, this ability was not due to extrasensory perception or a sixth sense," he said.
In the study, observers were presented with pairs of colour photographs, both of the same female. In some cases, her appearance would be different in the two photographs. For example, the individual might have a different hairstyle.
Each photograph was presented for 1.5 seconds with a 1 second break between them. After the last photograph, the observer was asked whether a change had occurred and, if so, identify the change from a list of nine possible changes.
Results showed study participants could generally detect when a change had occurred even when they could not identify exactly what had changed.
For example, they might notice that the two photographs had different amounts of red or green but not be able to use this information to determine that the person had changed the colour of their hat.
This resulted in the observer "feeling" or "sensing" that a change had occurred without being able to visually identify the change.
Thus, the result that observers can reliably feel or sense when a change has occurred without being able to visually identify the change could be explained without invoking an extrasensory mechanism, researchers said.
The study was published in the journal PLOS ONE.

comment:- wrong results due to wrong methods and wrong ideas of what is a sixth sense
What is sixth sense?
Sixth sense, or subtle perception ability, is our ability to perceive the subtle-dimension or the unseen worlds;
It also includes our ability to understand the subtle cause and
effect relationship behind many events, which is beyond the
understanding of the intellect.
Extrasensory perception (ESP),
clairvoyance, premonition, intuition are synonymous with sixth sense or
subtle perception ability
we perceive it through the five subtle-senses, the subtle-mind and the subtle-intellect - more popularly known as our sixth sense.
When the
sixth sense is developed or activated, it helps us to experience the
subtle-world or subtle-dimension.
How does one develop the sixth sense?
The subtle-world is all around us, however, we cannot perceive this world. Even though we cannot perceive the subtle-world, it impacts our lives to a great extent.In order to tune into this world we need our sixth sense
Sixth se
nse (ESP) and gender
Females, in general, have a stronger sixth sense than men. An
extrasensory perception (ESP) ability comes more naturally to women and
women are more likely to be intuitive than men. One of the main reasons
for this is that men are more intellectually oriented and tend more
towards the rational side.When the content of the knowledge is totally alien to the receiver’s field of knowledge.
Sixth sense, premonitions and time and space
Sometimes people have premonitions about things to happen, or a gut feeling about events that have happened in the past. This is possible in two ways:-
Through subtle-bodies:
The premonition (information) has been put into their sub-conscious mind by subtle-bodies. In most cases, the subtle-bodies or entities are ghosts
These subtle-bodies in some cases have the ability to see across time.
-
Accessing the Universal Mind and Intellect:
There are seven layers to the Universal Mind and Intellect. Depending on one's grade of sixth sense, a person may be able to tap into a lower or higher layer of the Universal Mind and Intellect.
clairvoyance (information received from a distant place) and
precognition (information received from a distant time),
the information is received from subtle-bodies and not through one’s ability to access the Universal Mind and Intellect.

Even microbes have a Dalal Street

NEW YORK: Ever heard of a biological market where microbes set up shops, bid and fight for a better trading partner?
Sounds crazy but according to a new study, microbes in our body set up their own markets, compare bids for commodities, hoard to obtain a better price and generally behave in ways share traders do at Dalal Street.
"We have long been aware that trades among a wide range of organisms are not blind exchanges but instead ones shaped by 'market conditions' such as price, quality and competition," said Joan Strassmann, professor at Washington University in Missouri, US.
"Single-celled organisms had been shown to avoid bad trading partners, build local business ties, diversify or specialize in a particular commodity, save for a rainy day, eliminate the competition and otherwise behave in ways that seem to follow market-based principles," he added.
They even foresee practical applications of the work. It might be possible, for example, to manipulate 'market conditions' in crop fields to drive nitrogen-fixing bacteria to trade more of their commodity - a biologically available form of nitrogen - with crop plants, said the study that appeared in the journal Proceedings of the National Academy of Sciences.
"The microscopic nature of microbial systems means it is easy to misunderstand their interactions. An economic framework helps us focus on what is important," said David Queller from Washington University.
"For biological markets to evolve, you actually only need that individuals can detect co-operators and respond by rewarding them with more resources," said Gijsbert Werner, a doctoral candidate at Vrijie Universiteit in Amsterdam, The Netherlands.
The researchers found that the fungi compare the resources on offer by different plants, and adjust their resource allocations accordingly.
Some fungi even hoard resources until they get a better deal, the study added.

MASSACHUSETTS: Seventeen-years-old Sam Berns, whose battle with a rare genetic condition that accelerates the aging process became the subject of an HBO documentary has died.
Berns, of Foxborough, Massachusetts, died on Friday after complications from Hutchinson-Gilford progeria syndrome, commonly known as progeria. The Progeria Research Foundation, which was founded by his parents, announced his death.
Berns was diagnosed with progeria when he was 22 months old. His parents founded the nonprofit foundation after encountering a lack of information and research on the condition, whose victims live an average of 13 years.
The work by his parents, Leslie Gordon and Scott Berns, who are doctors, on behalf of progeria patients is featured in the documentary " Life According to Sam.'' The exposure has brought greater recognition to the condition, which causes musculoskeletal degeneration, cardiovascular problems and other symptoms associated with aging.
New England Patriots owner Robert Kraft mourned Berns' death, saying he had invited the teen to be the football team's honorary captain for Saturday night's playoff game against the Indianapolis Colts and was looking forward to spending time with him and his family.
"I loved Sam Berns and am richer for having known him,'' Kraft said in a statement Saturday.
Kraft, after being introduced to Berns and attending the HBO premiere of the documentary in New York in October, made a $500,000 matching pledge to the foundation. Berns, a sports fan who was invited to a Patriots practice that month, gave the players an impromptu motivational speech, the Boston Globe reported.
Berns was asked to name his favorite player. He didn't have one. It takes a team to succeed, he said.
