What if the universe’s secrets were hiding in the innards of a black hole? Scientists seem to think so.

For long, black holes existed in Hollywood films and science fiction books. But when the first-ever image of one was released last year, the interest in black holes and their anatomy has increased.

Pōwehi

One of such black holes - Pōwehi is allegedly a repository of all of universe’s history. According to a report in New Scientist, the rings of light trapped in the hole’s orbit may be a historical record of its kind.

Comparing the rings of light or photons to a tree, or frames that constitute a film, scientists believe it’s where the history of all universe is stored. In essence, this would make black holes a constituent yet small piece of the puzzle we call the universe, and know very little about.

Most knowledge about black holes is extrapolatory, based on juxtapositions and far-off observations, and perhaps we will never know what lies inside one of the holes, as&nbsp;the gravitational pull in the holes is strong enough to swallow everything that crosses its path! What scientists do know is that black holes are created in the aftermath of a star’s death, or a supernova.

Photon rings are important

The series of photon rings in the black hole can help scientists study its properties, much like studying branches of a tree to understand its structure.

“Together, the set of subrings are akin to the frames of a movie, capturing the history of the visible universe as seen from the black hole,” the paper asserted.

However, black holes are complex entities. Even if we were to somehow access photon rings, we would need to do it on time.

New rings are formed every six days, and they last no longer than this time period, after which the hole swallows them.

So, we may not be able to peek into the past, or perhaps the future, just yet!

Black holes may be repositories of all of universe's history!

A team of astronomers, including some from Chile, has found a relationship between the collision of galaxies and voracious black holes that could be a key element in solving heretofore unanswered questions in astrophysics, investigators said.

"Thanks to this work, today we're closer to resolving two big enigmas in astrophysics: how galaxies form and how supermassive black holes living in the center of them grow, and - even more important - why both processes are connected," Ezequiel Treister, with Chile's Astrophysics Institute at the Universidad Catolica, said in a communique sent to EFE.

"What we discovered is that almost 20 percent of the fast-growing black holes ... are associated with the last phases of the process of galaxy collision. That is, a little before they merge and form a single colossal black hole," said Treister, who is also a researcher at the Center for Excellence in Astrophysics and Related Technologies (CATA).

The research was recently published in Nature magazine and combined 20 years of observations with the Hubble Space Telescope, data obtained by the Neil Gehrels Swift X-ray Observatory, both operated by NASA, and the Keck optical telescope in Hawaii.

The study itself lasted for eight years and included about a dozen scientists, headed by Michael J&nbsp;Koss, with Eureka Scientific Inc. in California, who emphasised that the work shows what will happen when the Milky Way merges with the Andromeda Galaxy and their respective central black holes spiral into one another.

The research could lead to predictions about the type of galaxies in which these cosmic events occur, he added.

The work analysed almost 100 galaxies containing growing black holes, along with some 200 inactive galaxies used for comparative purposes, Treister said.

Those galaxies are located at a maximum distance of a few billion light years.

The study concluded that black holes that are surrounded by dust and gas produced by galactic mergers have a greater probability of participating in this type of process, he said.

The team now intends to study how the black holes are fed and grow during the galaxy-merger process and how they interact with the galaxies that house them, but to get the viewing resolution required for that task, which is 10 times greater than that provided by the Hubble, they will need to use other instruments, including the Atacama Large Millimeter/submillimeter Array observatory in northern Chile consisting of 66 huge antennas set up more than 5,000 meters (16,400 feet) above sea level.

Astronomers find relationship between colliding galaxies, black holes

Stephen Hawking's family have invited time travellers to his memorial service, seeking to tackle one of the curiosities that eluded the British physicist during his extraordinary life.

The world's most recognisable scientist died in March aged 76 after a lifetime spent probing the origins of the universe, the mysteries of black holes and the nature of time itself.

Members of the public have been invited to apply for tickets to attend a celebration of Hawking's life at a memorial service in Westminster Abbey on June 15 where his ashes will be interred alongside the graves of Isaac Newton and Charles Darwin.

Those wishing to apply have to fill in a form and state their date of birth, which can be any day up to the end of 2038.

The option to have a date of birth in the future was spotted by London blogger ianvisits who wrote on his site: "Professor Hawking once threw a party for time travellers, to see if any would turn up if he posted the invite after the party.

"None did, but it seems perfect that the memorial website allows people born in the future to attend the service. Look out for time travellers at the Abbey."

Sarah Bridle, a professor of Astrophysics at the University of Manchester, told BBC Radio that Hawking, who was confined to a wheelchair for most of his life, had remained curious about the potential for time travel, even after his party in 2009.

"He was curious and he had a great sense of humour," she said. "He said he combined his two favourite things, experiments and champagne to put on this party."

Time travellers invited to Stephen Hawking send-off

Friends, family and colleagues of British scientist Stephen Hawking will gather Saturday to pay their respects at his private funeral in Cambridge, where he spent most of his extraordinary life.

Hawking, who died on March 14 at the age of 76, was famously an atheist but his children Lucy, Robert and Tim have chosen the town's university church, St Mary the Great, to say their farewell.

"Our father's life and work meant many things to many people, both religious and non-religious. So, the service will be both inclusive and traditional, reflecting the breadth and diversity of his life," they have said.

Tributes poured in from around the world upon Hawking's death, from Queen Elizabeth II to NASA, reflecting his huge impact as a physicist and an inspiration, in his refusal to give up in the face of physical disability.

But the service at St Mary church -- a short distance from Gonville and Caius College where Hawking worked for more than 50 years -- will only be open to those who knew him, followed by a private reception at Trinity College.

A wider audience will attend a thanksgiving service at Westminster Abbey in London on June 15, where Hawking's remains will be buried near the grave of another legendary scientist, Isaac Newton.

Ahead of the funeral, Gonville and Caius College released new black and white photographs of Hawking taken in 1961 at a summer school for young astrophysicists at a castle in Sussex, southern England, when he was 19.

They showed him playing croquet and in a sailing dinghy, two years before he began experiencing the first symptoms of the motor neurone disease that would later leave him almost completely paralysed.

Fellow students contacted by the college recalled his left-wing views and his mischievous sense of humour, with one describing how he replaced the Royal Navy flag on the castle flagpole with the Communist hammer and sickle.

Hawking defied predictions that he would only live for a few years, although his rare condition -- amyotrophic lateral sclerosis (ALS) -- gradually robbed him of mobility.

He was confined to a wheelchair, almost completely paralysed and unable to speak except through his trademark voice synthesiser.

But the illness did nothing to dull his mind, and Hawking became one of the world's best-known and most inspiring scientists, known for his brilliance and his wit.

His work focused on bringing together relativity -- the nature of space and time -- and quantum theory -- how the smallest particles behave -- to explain the creation of the Universe and how it is governed.

But he was also a global star -- his 1988 book "A Brief History of Time" was an unlikely worldwide bestseller, and he appeared as himself in TV shows from "The Simpsons" to "Star Trek: The Next Generation".

Born on January 8, 1942 -- 300 years to the day after the death of the father of modern science, Galileo Galilei -- Hawking died in his home in Cambridge on the 139th anniversary of the birth of Albert Einstein.

After taking his undergraduate degree at the University of Oxford, he moved to Cambridge for his doctorate and stayed there for the rest of his career.

Hawking's family has asked six college porters, many of whom provided support for Hawking when he visited for dinners and other events, to carry his coffin.

Family, friends bid farewell to Stephen Hawking

Black holes may be a portal that can transfer matter to another part of the universe, rather than destroying it, a new study has claimed. 
 
One of the biggest problems when studying black holes is that the laws of physics as we know them cease to apply in their deepest regions. 
 
Large quantities of matter and energy concentrate in an infinitely small space, the gravitational singularity, where space-time curves towards infinity and all matter is destroyed. 
 
However, a new study at the Institute of Corpuscular Physics (IFIC) in Spain suggests that matter might, in fact, survive its foray into these space objects and come out the other side. 
 
Scientists propose considering the singularity as if it were an imperfection in the geometric structure of space-time. 
 
By doing so they resolve the problem of the infinite, space-deforming gravitational pull. 
 
Black holes- a theoretical laboratory 
 
&quot;Black holes are a theoretical laboratory for trying out new ideas about gravity,&quot; said Gonzalo Olmo, a researcher at the University of Valencia (UV) in Spain. 
 
Specifically, in this work he has applied geometric structures similar to those of a crystal or graphene layer, not typically used to describe black holes, since these geometries better match what happens inside a black hole. 
 
&quot;Just as crystals have imperfections in their microscopic structure, the central region of a black hole can be interpreted as an anomaly in space-time, which requires new geometric elements in order to be able to describe them more precisely,&quot; said Olmo. 
 
Using these new geometries, the researchers obtained a description of black holes whereby the centre point becomes a very small spherical surface.geometries, the researchers obtained a description of black holes whereby the centre point becomes a very small spherical surface. 
 
This surface is interpreted as the existence of a wormhole within the black hole. 
 
&quot;In the first instance we resolve the problem of the singularity, since there is a door at the centre of the black hole, the wormhole, through which space and time can continue,&quot; Olmo said. 
 
The wormhole predicted by the equations is smaller than an atomic nucleus, but gets bigger with the charge stored in the black hole. 
 
So, a hypothetical traveller entering a black hole of this kind would be stretched to the extreme, or &quot;spaghettified,&quot; and would be able to enter the wormhole. Upon exiting they would be compacted back to their normal size. 
 
Seen from outside, these forces of stretching and compaction would seem infinite, but the traveller himself, living it first-hand, would experience only extremely intense, and not infinite, forces. 
 
The model proposed by the researchers posits that matter would not be lost inside the singularity, but rather would be expelled out from the other side through the wormhole at its centre to another region of the universe. 
 
The study was published in the journal Classical and Quantum Gravity.
