The big bang poses a big question: if it was indeed the cataclysm that blasted our universe into existence 13.7 billion years ago, what sparked it? Three researchers at the Perimeter Institute for Theoretical Physics and the University of Waterloo propose that the big bang could be the three-dimensional "mirage" of a collapsing star in a universe profoundly different than our own.

The event horizon of a black hole — the point of no return for anything that falls in — is a spherical surface. In a higher-dimensional universe, a black hole could have a three-dimensional event horizon, which could spawn a whole new universe as it forms.

 

 

It could be time to bid the Big Bang bye-bye. Cosmologists have speculated that the Universe formed from the debris ejected when a four-dimensional star collapsed into a black hole — a scenario that would help to explain why the cosmos seems to be so uniform in all directions.

The standard Big Bang model tells us that the Universe exploded out of an infinitely dense point, or singularity. But nobody knows what would have triggered this outburst: the known laws of physics cannot tell us what happened at that moment.

“For all physicists know, dragons could have come flying out of the singularity,” says Niayesh Afshordi, an astrophysicist at the Perimeter Institute for Theoretical Physics in Waterloo, Canada.

It is also difficult to explain how a violent Big Bang would have left behind a Universe that has an almost completely uniform temperature, because there does not seem to have been enough time since the birth of the cosmos for it to have reached temperature equilibrium.

To most cosmologists, the most plausible explanation for that uniformity is that, soon after the beginning of time, some unknown form of energy made the young Universe inflate at a rate that was faster than the speed of light. That way, a small patch with roughly uniform temperature would have stretched into the vast cosmos we see today. But Afshordi notes that “the Big Bang was so chaotic, it’s not clear there would have been even a small homogenous patch for inflation to start working on”.

Afshordi and his colleagues turn their attention to a proposal made in 2000 by a team including Gia Dvali, a physicist now at the Ludwig Maximilians University in Munich, Germany. In that model, our three-dimensional (3D) Universe is a membrane, or brane, that floats through a ‘bulk universe’ that has four spatial dimensions.

Ashfordi's team realized that if the bulk universe contained its own four-dimensional (4D) stars, some of them could collapse, forming 4D black holes in the same way that massive stars in our Universe do: they explode as supernovae, violently ejecting their outer layers, while their inner layers collapse into a black hole.

In our Universe, a black hole is bounded by a spherical surface called an event horizon. Whereas in ordinary three-dimensional space it takes a two-dimensional object (a surface) to create a boundary inside a black hole, in the bulk universe the event horizon of a 4D black hole would be a 3D object — a shape called a hypersphere. When Afshordi’s team modelled the death of a 4D star, they found that the ejected material would form a 3D brane surrounding that 3D event horizon, and slowly expand.

The authors postulate that the 3D Universe we live in might be just such a brane — and that we detect the brane’s growth as cosmic expansion. “Astronomers measured that expansion and extrapolated back that the Universe must have begun with a Big Bang — but that is just a mirage,” says Afshordi.

The model also naturally explains our Universe’s uniformity. Because the 4D bulk universe could have existed for an infinitely long time in the past, there would have been ample opportunity for different parts of the 4D bulk to reach an equilibrium, which our 3D Universe would have inherited.

The picture has some problems, however. Earlier, the European Space Agency's Planck space observatory released data that mapped the slight temperature fluctuations in the cosmic microwave background — the relic radiation that carries imprints of the Universe’s early moments. The observed patterns matched predictions made by the standard Big Bang model and inflation, but the black-hole model deviates from Planck's observations by about 4%. Hoping to resolve the discrepancy, Afshordi says that his is now refining its model.

Despite the mismatch, Dvali praises the ingenious way in which the team threw out the Big Bang model. “The singularity is the most fundamental problem in cosmology and they have rewritten history so that we never encountered it,” he says. Whereas the Planck results “prove that inflation is correct”, they leave open the question of how inflation happened, Dvali adds. The study could help to show how inflation is triggered by the motion of the Universe through a higher-dimensional reality, he says.

They stolen my theory:
“The majority of Ferent matter(Dark matter) is the core of the supermassive black hole” Adrian Ferent(Jan 14, 2015)
I discovered: Big Bang and Big Crunch oscillation, from Ferent wall.
I calculated the density inside of that Black Hole after the Big Crunch: The Ferent universe will collapse to the state where it began and the Big Bang will start again from Ferent wall, the Ferent density ρF = mF / lF3 = 8.94 × 10181 kg/m3
That Black hole was at Ferent wall not at Planck wall, their theory!

'Most of these black holes are dormant, but a few per cent are 'active' meaning that they are devouring material from their host galaxy, forming an accretion disc that feeds the black hole.'

How can black holes go dormant? Wouldn't it 'puff' and disappear? Which comes first; a black hole or a galaxy? Is a black hole a prerequisite for a galaxy to form? I think so.

The massive gravitational pull of a black hole attracts matter, that form galaxies, full of stars and planets. Lone black holes are waiting to attract matter from supernova's, to form future galaxies.

Where do black holes come from? A higher dimension, a seed planted by dimensional creatures to form energy engine they can derive energy from. They use a worm hole to flood our universe with energy to form a singularity.

The energy pouring in through the singularity is transforms into heavy matter, to give birth to a black hole, after it reaches a critical mass. Much like priming an engine to get it started, But they use black holes to start their engine.

They can selectively use their energy, to give birth to a black hole that will eventually attract matter and convert it into useable energy, feeding it back into a higher dimension.
Looking at it from that perspective, it make sense. They are using our universe black holes, to convert newtonian matter into energy, that feed their dimension(s).

If they need more energy to sustain their higher dimensionality, they just create signulaity, pouring energy in to create another big bang that will create a new universe to draw energy from, via black holes.

I doubt if black hole ever goes dormant. More likely it passes a threshold where it is self-sustaining, like a car driving on eco mode. It appears domain but energy coming out, is trickle flowing back in.

A gravitational engine on eco mode. If one fails, then they others to draw from.

Yeah, right. What gave birth to the black hole? Matter did not create itself from nothing.
There is a secret, somewhere or there was. Nobody knows, probably nobody will ever know what
happened. Let's eat it, simply.

To: ADRIAN FERENT. What is your academic background, sir, and degrees which you hold? Have you published scientific papers in any credible scientific journal? Also, why are comments disabled on your YouTube videos?

*Steve Savage "King of the Beasts"*

So where did the four-dimensional star come from that supposed gave birth to "our" universe?
See, this just pushes the question of "where did it all come from" further back in time, it really doesn't answer anything.

"Three researchers at the Perimeter Institute for Theoretical Physics and the University of Waterloo propose that the big bang could be the three-dimensional "mirage" of a collapsing star in a universe profoundly different than our own."

"Could" be the "mirage" of an imaginary universe. Sound science.

I was gonna make a comment similar to zigzag2016's and Olingoncello's. "Could be." Yeah. Exactly. Get a little tired of seeing scientific advancement treated like pop news. Or theoretical possibilities treated as fact.

Anyone with the tiniest grain of understanding knows that ideas which lead to an infinite recession, are, while they cannot be proven untrue, useless for logic, math, or science.

That's what he meant when Bertrand Russell said, "It's turtles all the way down, Madam." At least, I think it was Russell who originally said it. He had the wit.

not turtles all the way down, just turtles everywhere.

turtles can spawn from nothing as long as they can exactly cancel out as seen in quantum physics.
this can lead to situations where some turtles "escape" given enough time and enough turtles you get gravity which brings us the real machanism for creating more energy! as matter falls toward matter it gains added kinetic energy, this is a neverending mechanism in the universe, the effects are huge near black holes as matter becomes more massive when accelerated to near light speeds! so whenever the first particle sparked doesnt matter, where it happened doesnt matter either. eventually since time is infinite it will happen everywhere! as far as the 4D black hole, i dont think we need to go as far as 4D, but a black hole could easily stretch space far enough (infinately) to accomodate our little pocket of universe and the stretching of time creates a 1-way door through the black hole. the white hole on the other hand is the inside out of the black hole, the stuff "falling out" of the white hole is all "caught up" from a universe of time the parent hole had to feed, some of the stuff being billions or trillions of years older than other stuff but all ejected at the same time, the time stretching is critical to understanding the uniformity of the event, i could go on about this mechanism for quite some time.

i would also like to note that matter and energy are constantly created and the proof is that we are all here.
