Could the famed "Big Bang" theory need a revision? A group of theoretical physicists suppose the birth of the universe could have happened after a four-dimensional star collapsed into a black hole and ejected debris.
Before getting into their findings, let's just preface this by saying nobody knows anything for sure. Humans obviously weren't around at the time the universe began. The standard theory is that the universe grew from an infinitely dense point or singularity, but who knows what was there before?
"For all physicists know, dragons could have come flying out of the singularity," stated Niayesh Afshordi, an astrophysicist with the Perimeter Institute for Theoretical Physics in Canada who co-authored the new study.
So what are the limitations of the Big Bang theory? The singularity is one of them. Also, it's hard to predict why it would have produced a universe that has an almost uniform temperature, because the age of our universe (about 13.8 billion years) does not give enough timeas far as we can tellto reach a temperature equilibrium.
Most cosmologists say the universe must have been expanding faster than the speed of light for this to happen, but Ashford says even that theory has problems: "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."
This is what the physicists propose:
The long and the short of it? To bring this back to things that we can see, it is clear from observations that the universe is expanding (and indeed is getting faster as it expands, possibly due to the mysterious dark energy). The new theory says that the expansion comes from this 3-D brane's growth. But there is at least one limitation.
While the model does explain why the universe has nearly uniform temperature (the 4-D universe preceding it would have existed it for much longer), a European Space Agency telescope called Planck recently mapped small temperature variations in the cosmic microwave background, which is believed to be leftovers of the universe's beginnings.
The new model differs from these CMB readings by about four percent, so the researchers are looking to refine the model. They still feel the model has worth, however. Planck shows that inflation is happening, but doesn't show why the inflation is happening.
"The study could help to show how inflation is triggered by the motion of the universe through a higher-dimensional reality," the researchers stated.
That theory sucks!
I remember hearing this idea, or something similar, on Art Bell back in the 1990’s
Where did the four-dimensional star and the black hole come from?
“the 4D universe preceding it”
Where did the 4D universe come from?
From another universe preceding it?
That line of thought is logically fallacious — infinite regression.
Where then did the 4D universe come from?
Nothing causes nothing to come into existence. Causeless effects?
“For all physicists know, dragons could have come flying out of the singularity,”
It was flying pigs and unicorns that came out of the singularity.
Racists to say and as ? blacker than black ?
What really is the difference between a singularity and a black hole? How can someone theorize a point with all the mass in the universe, without that point being a black hole?
What holds up the world?
It is held on the back of a giant turtle.
What holds up the turtle?
There is a giant elephant under each foot.
What holds up the elephants?
It’s elephants all the way down!
Google “Halton Arp”
nobody says how god created it. maybe he used a blackhole? that would explain a lot.
I think they are content to explain anything; e.g., the uniform temperature problem, and aren’t trying to explain everything. So we are as puzzled by what came before their 4-D universe as we’ve always been about what preceded the Big Bang. Do I claim to understand how their idea explains away the temperature problem? Heck, no, I wish! :-)
Each elephant stands on another one. Eventually the bottom elephant stands on a tortoise. That takes care of that.
It is said that the light of a distant star takes thousands, maybe millions of years to reach Earth. How do we know if those stars still exist? Maybe they exploded or burned out long ago, and we are just now seeing their light. Maybe the entire visible universe is just an illusion of light. Something to chew on.
bush did it....
in the so called natural world...Nothing comes from nothing...ever
I appreciate the manner in which you phrased that.
