World-Class Team Says: "Time was Inherited from an Earlier Universe"

  NGC300_Halpha_l

A world-class team of physicists studying the cosmic microwave background (CMB), light emitted when the Universe was just 400,000 years old have claimed that our view of the early Universe may contain the signature of a time before the Big Bang. Their discovery may help explain why we experience time moving in a straight line from yesterday into tomorrow.

The CMB is relic radiation that fills the entire Universe and is regarded as the most conclusive evidence for the Big Bang. Although this microwave background is mostly smooth, the Cobe satellite in 1992 discovered small fluctuations that were believed to be the seeds from which the galaxy clusters we see in today's Universe grew.

Dr Adrienne Erickcek, from the California Institute of Technology (Caltech), and colleagues believe these fluctuations contain hints that our Universe "bubbled off" from a previous one. Their data came from Nasa's Wilkinson Microwave Anisotropy Probe (WMAP), which has been studying the CMB since its launch in 2001.

Their model suggests that new universes could be created spontaneously from apparently empty space. From inside the parent universe, the event would be surprisingly unspectacular.

Describing the team's work, California Institute of Technology professor Sean Carroll explained that "a universe could form inside this room and we’d never know".

The inspiration for their theory isn't just an explanation for the Big Bang our Universe experienced 13.7 billion years ago, but lies in an attempt to explain one of the largest mysteries in physics - why time seems to move in one direction. The laws that govern physics on a microscopic scale are completely reversible, and yet, as Professor Carroll commented, "no one gets confused about which is yesterday and which is tomorrow." Carroll added: "Every time you break an egg or spill a glass of water you're learning about the Big Bang."

Physicists have long blamed this one-way movement, known as the "arrow of time", on a physical rule known as the second law of thermodynamics, which insists that systems move over time from order to disorder.

This rule is so fundamental to physics that pioneering astronomer Arthur Eddington insisted that "if your theory is found to be against the second law of thermodynamics I can give you no hope; there is nothing for it but to collapse in deepest humiliation".

The second law cannot be escaped, but Carroll pointed out that it depends on a major assumption - that the Universe began its life in an ordered state.

In his presentation, the Caltech astronomer explained that by creating a Big Bang from the cold space of a previous universe, the new universe begins its life in just such an ordered state. The apparent direction of time - and the fact that it's hard to put a broken egg back together - is the consequence.

Much work remains to be done on the theory: the researchers' first priority will be to calculate the odds of a new universe appearing from a previous one. In the meantime, the team has turned to the results from WMAP. Detailed measurements made by the satellite have shown that the fluctuations in the microwave background are about 10% stronger on one side of the sky than those on the other.

Carroll conceded that this might just be a coincidence, but pointed out that a natural explanation for this discrepancy would be if it represented a structure inherited from our universe's parent.

Meanwhile, Professor Carroll urged cosmologists to broaden their horizons: "We're trained to say there was no time before the Big Bang, when we should say that we don't know whether there was anything - or if there was, what it was."

If the Caltech team's work is correct, we may already have the first information about what came before our own Universe.

you dont know this. it is all guess work. too many scientist act like they fucking know everything when in reality we cant even begin to comprehend how this shit REALLY happened

you guys are starting to get just as bad as the christfags at how you spout off your nonsense as "fact"

and give me any of that "its just a theory" shit

the fact that you publish this drivel is proof enough of your ignorance

"the fact that you publish this drivel is proof enough of your ignorance"

Irony is lost on you, isn't it?

No scientist says "It's just a theory," in scientific terms a "theory" means that given all current information, what has been discovered has been proven. Take some science classes and come back and see me.

"you guys are starting to get just as bad as the christfags"

Right, because attempting to measure and figure out the universe we live in is the exact same as taking literally what some bronze age, illiterate, mechanths, who knew nothing about the world, wrote down thousands of years ago.

"we cant even begin to comprehend how this shit REALLY happened"

Are you retarded? The whole point of science is trying to figure these things out. 200 years ago if you told someone you could take an exact representation of something you see right in front of you and send it, through the air, to someone miles away, they'd say you're crazy. And that you can't possibly comprehend how information could move at the speed of light. Get off your high horse.

The concern lies not with why these scientists are exploring different ideas, but rather with the blind subscription by the masses to those ideas. Science is constantly proving itself wrong, which is great in that it always seeks the truth and seeks to correct its errors. The problem is getting behind an idea you know is almost certainly going to be proven wrong. I have trouble with theoretical physics because all it ever amounts to is our best educated guess at the moment. When we look down upon the Bible, we fail to acknowledge that their explanations for their world were their best educated guesses at the time. We fail to acknowledge that the priests of that time were respected in the same way we currently respect our scientists. Consequently, we fail to acknowledge that these scientists making educated guesses are the modern day priests in the religion of science.

I'm not saying they're wrong, nor am I saying their quest for knowledge is in any way inappropriate. They could very well be right. Statistically I'd imagine they're wrong (these are hypothetical statistics, so I can't provide evidence to support that), but who knows. Maybe we were randomly spawned out of another universe. Maybe I'm living on part of an electron in part of an atom in part of a rollercoaster car. Maybe this is all a dream. Maybe there's a flying spaghetti monster. You know as well as I do that you have no idea.

Yero, it does not make sense to compare science to a religion when scientific theories are based on educated reasoning and religions are defined by faith.

this is some pretty funny shit. these scientists, who never even been outside this tiny planet, make such claims. does time operate the same on a different part of this universe? there are so many questions... physicists really dont know anything, but like to extrapolate universal laws based on what is observed at one point ie. earth.

"we cant even begin to comprehend how" and yet here we are posting on our personal computers. pretty damned good stuff from people who, if you believe "angry", can't even begin to figure stuff out.

Sean Carroll, you seems to have a productive mind with great amount of spirituality content. Your theory supports the pre-existence of the universe and thus supports the existence of multi-verses. it seems correct to me conjecturally. But time scales may not be the same in different universes. Each should have its own unique time scale. There is thus something deeper associated with time. It determines the character of the individual universe and is thus very much to do how universes get generated. The concepts of space and time have much deeper meanings that we need to understand yet. To me, homogeneity and inhomogeneity in these play a role. How these get developed and then disappear perhaps determine the span of the universe and even the span of the intelligent life forms born within each. I do not have your Internet Id but it will be nice if we can discuss such issues further. Narendra nath

read the flower of life by drunvalo melchizedek. your questions will be answered.

Of course there was time before the big bang. All of that matter had to come from somewhere. If something moves/collects/grows/decays then time exists as a means to measure those things.

This is exactly what Roger Penrose proposed in his theory of Conformal Cyclic Cosmology!

Everything even universes can be created or destroyed instantly or change practically forever. A universe need not be considered larger then a tiny particle. Tiny earths might exist that are so tiny and have fleeting time existences and nothing we could ever know would change. Same with other universes like our own, the matter came from somewhere larger then our universe, and it is easy to make a universe out of nothing in reality.

Agree that the so-called material universes were born out of ' nothing '. Nothing has generated everything as silence contains noise but not vice versa. Silence and nothing are synonimous that carry the mysteries of everything that we say exist as material world!

time cannot move backwards because time does not exist, is just an abstract term that describe the progress/movement of complex systems upwards from the quark/atom level/solar system/galaxy/etc based on the lows of physics, chemistry, etc, we only invented this term because we can remember things that happen and we can predict how objects will behave in future under certain circumstances based on old observations. A "day" does not exist, is just our way of counting how long will take the sun to revolve around the earth, but no day is the same with the previous one even the sun appears to repeat the movement and we can generalize it that is the same movement, is actually a new cycle.

time do not run slower next closer to bigger mass but systems progress slowly at the atom level influenced by the mass of the objects they are next to

The mistaken information is the second law of thermodynamics, which is incomplete - the polar opposite force that takes disorder into order is the force (or flower) of life. Physicists keep failing to acknowledge this, thus, their theories are incomplete, and hence, in error. One modern physicist, Nassim Haramein, has a new "spin" on the GUT that I believe is in the right direction (which is a dualistic spiral motion). Check out theresonanceproject.org, and be enlightened. Melchidezik's work is very interesting, too. But in the end, a lot of these posters are right, we don't know shit, Well, maybe that's all we know....

In Aether Wave Theory the Universe behaves like dense gas with giant density fluctuations in the role of galaxies, which are condensing and evaporating again rather randomly. The appearance of such steady state Universe is similar to the perspective of observation of water surface with its own ripples and/or landscape under haze: we cannot see at unlimited distance, but there is no actual beginning of Universe or end as a whole.

If Time has been inherited from a previous Universe, then there is a possibility that Space also has been inherited. This could only mean that what we are calling the big bang might never have happened in the past.

@ Futaciosu : My thoughts exactly!

The big questions, the Holy Grail of Physicsm are "THE" quest, I suppose.From my view between The Military, DARPA, NASA, and the reams of esoteric research, this country is completely avoiding the facts that the wheels could be coming off the train.Personal debt, The Trade deficit, The National Debt,the lack of decent regulations and the lack of confidence in the markets. does not bode well for future funding.Instead of each department insisting that their work is of the highest importance, I would like to see everybody start focusing in on the problems at hand.You can do it voluntarily, or wait, not focus in, and bam the plug will be pulled.

@futaciosu
"A "day" does not exist, is just our way of counting how long will take the sun to revolve around the earth"

It was proved long ago that the earth revolves around the sun.
I fart in your general direction.

These stories always bring out the ignorant commenters. Anti-intellectuals, pseudoscientific idiocy, paranoid fantasy, people like Lee Stevens who think they have the right to determine what gets investigated and what does not.

Screw them all. When idiots like that raise their heads, smack them down.

I have tertiary syphilis.

It's funny how people can tear down an idea before sufficient evidence is given for it to be proven false. Remember we are bound to our five senses within our three dimensional world. Just because you're five little senses can't perceive something does not make it fictional. If you are truly a man of science you would have an open mind to everything including religion, so to the thick-headed twat that thinks "christfags" and the scientists exploring this idea are all "ignorant" please realize that we have much to discover and the only way to do so is by theorizing rather than scratching your ass and saying "HAY I NO EVRYTING BECUZ I GOTS A DUGREE ONLINE DAT SAYS SO"
