Came across another interesting article this evening:

http://finance.yahoo.com/news/astrophysicists-plan-announce-major-discovery-222124829.html

Scientists will announce a "major discovery" on Monday, March 17, at the Harvard-Smithsonian Center for Astrophysics, according to a news release from the institution.

The big news will be delivered at a press conference, streamed live starting at 11:55 a.m. EDT at this link. Business Insider will also be covering the announcement.

Rumors surrounding the topic of the discovery are starting to fly, but nothing has been confirmed and the media alert offered no hints.

The Guardian reports on speculation that the discovery has to do with finding of evidence of primordial gravitational waves, ripples in the fabric of spacetime that were produced in the early universe. The imprint they left when the universe was born 13.82 billion years ago would give us an idea of what the universe was like when it just came into existence.

According to The Guardian: "The signal is rumored to have been found by a specialized telescope called Bicep (Background Imaging of Cosmic Extragalactic Polarization) at the south pole."

Gravitational waves were the last untested prediction of Albert Einstein’s General Theory of Relativity.

"It's been called the Holy Grail of cosmology," Hiranya Peiris, a cosmologist from University College London, told The Guardian. "It would be a real major, major, major discovery."

There are still reasons not to get ahead of ourselves.

Even if they do announce they've discovered these signatures of the early universe, that data will need to be scrutinized by other scientists and confirmed by other experiments.

Phil Plait, who writes Slate's Bad Astronomy blog, said in a Facebook post that he will not speculate on the discovery. "If the rumors are false," he wrote, "then I've wasted my time, and that of others, and weakened the overall public appreciation of astronomy."

It's still fun to guess.
 
I was hoping they would announce that they have discovered that generally speaking they don't know what they're talking about! :lol:
 
scientists find gravity waves, think (publicly at least) that its from big bang

Another hit for the C's?

"In the most anticipated announcement in physics since the discovery of the Higgs Boson, the first detection of a gravitational wave has been reported. "
 
Re: scientists find gravity waves, think (publicly at least) that its from big bang

It is also being discussed here.

Yeah, they're still banging on about gravity & they still don't know what it is, only it's effects. Now they're focusing on gravity waves? Oh, if only they would talk about levity! ;)

Seriously, could this be another marker in the increasing chain of them? Weather fluctuations, geopolitical fluctuations, disappearing planes...

:lol: That is really funny. I needed that today. ;)
 
Okay, so they've detected gravity waves. We know they exist, Ark's talked about it (as well as the C's) a few times as I recall.

How does that prove the Big Bang theory exactly? I realize I'm no physicist, but it seems like another "that light up there in the sky doesn't look right, so it must be next to a black hole" kind of illogical reasoning.

I'm dumping this announcement in the same bin as anything related to "dark matter".

They seem pretty excited about it. It basically proves that their theory of expansion of the universe is true. And that the big bang is really most likely true. I, however don't understand all of the data that I've read though.
 
The inflation model that this supports is Andrei Linde's model. Linde himself has some interesting views about consciousness.

Via a facebook group I'm in:

(1) From an interview:

Philip Clayton:
Would you, then, be inclined to have some sort of realm of truths that were not fully scientific, some realm remaining for the religious or spiritual?

Andrei Linde:
I think that this area does exist, but traditional science doesn’t want to recognize it. The idea of physics is that eventually it will have all its explanations in itself, but this is not what is actually occurring with the development of science. There are always windows for expansion. The main goal of science is to make it a closed science, i.e. a self-sufficient science explaining everything. But there is no theorem saying that closed science does exist. There is one area where it might be manifestly non-closed, and people just do not want to look into it because they have good reasons to think that this is irrelevant for most of their purposes. This place is the description of consciousness. Some scientists think that consciousness is just a manifestation of matter, not something separate–that my thought is just the motion of electrons in my brain. From my perspective this is a very naive attitude which is simply a consequence of being too focused on the success of the materialistic model of the world.

2) From his essay, “The universe, life and consciousness”:
The universe and consciousness

Finally, let us turn to consciousness. According to standard materialistic doctrine, consciousness, like spacetime before the invention of general relativity, plays a secondary, subservient role, being considered just a function of matter and a tool for the description of the truly existing material world. Let us remember, though, that our knowledge of the world begins with perceptions, not with matter. I know for sure that my pain exists, my “green” exists, and my “sweet” exists. I do not need any proof of their existence, because these events are a part of me; everything else is a theory. Later we find out that our perceptions obey some laws, which can be most conveniently formulated if we assume that there is some underlying reality beyond our perceptions. This model of the material world obeying laws of physics is so successful that we too readily forget our starting point and come to think that matter is the only reality, and that perceptions are only helpful for its description. This assumption is almost as natural (and maybe as false) as our previous assumption that space is only a mathematical tool for the description of matter. In fact, we are replacing the reality of our feelings with a successful theory of an independently existing material world. And the theory is so successful that we almost never think about its limitations until we are forced to address those deep issues which do not fit into our model of reality.

It is certainly possible that nothing similar to the modification and generalization of the concept of spacetime will occur with the concept of consciousness in the coming decades. But the thrust of research in quantum cosmology has taught us that the mere statement of a problem which might at first glance seem entirely metaphysical can sometimes, upon further reflection, take on real meaning and become highly significant for the further development of science. At this point, I would like to take a certain risk and formulate several questions for which we do not yet have any answers.

Is it not possible that consciousness, like spacetime, has its own intrinsic degrees of freedom, and that neglecting these will lead to a description of the universe that is fundamentally incomplete? What if our perceptions areas real (or maybe, in a certain sense, are even more real) than material objects? What if my red, my blue, my pain, are really existing objects, not merely reflections of the really existing material world? Is it possible to introduce a “space of elements of consciousness,” and investigate the possibility that consciousness may exist by itself, even in the absence of matter, just like gravitational waves, excitations of space, may exist in the absence of protons and electrons? Will it not turn out, with further scientific developments, that the study of the universe and the study of consciousness will be inseparably linked, and that, ultimately, progress in the one will be impossible without progress in the other? After the development of a unified geometrical description of the weak, strong, electromagnetic, and gravitational interactions, will the next important step not be the development of a unified approach to our entire world, including the world of consciousness?

All of these questions might seem somewhat naive, but it becomes increasingly difficult to investigate quantum cosmology without making an attempt to answer them. A few years ago it would have seemed equally naïve to ask why there are so many different things in the universe, why nobody has ever seen parallel lines intersect, why the universe is almost homogeneous and looks approximately the same at different locations, why spacetime is four-dimensional, and so on. Now, when inflationary cosmology provided a possible answer to these questions, one can only be surprised that prior to the 1980s, it was sometimes taken to be bad form even to discuss them.
It is best not to repeat old mistakes, but instead forthrightly to acknowledge that the problem of consciousness and the related problem of human life and death are not only unsolved, but at a fundamental level are virtually unexamined. It is tempting to seek connections and analogies of some kind, even if they are shallow and superficial ones at first, in studying another great problem that of the birth, life, and death of the universe. It may yet become clear that these two problems are not so disparate after all.

3) From the article “Does the Universe Exist if We're Not Looking?‘’:

Stanford University physicist Andrei Linde believes this quantum paradox gets to the heart of Wheeler's idea about the nature of the universe: The principles of quantum mechanics dictate severe limits on the certainty of our knowledge.

"You may ask whether the universe really existed before you start looking at it," he says. "That's the same Schrödinger cat question. And my answer would be that the universe looks as if it existed before I started looking at it. When you open the cat's box after a week, you're going to find either a live cat or a smelly piece of meat. You can say that the cat looks as if it were dead or as if it were alive during the whole week. Likewise, when we look at the universe, the best we can say is that it looks as if it were there 10 billion years ago."

Linde believes that Wheeler's intuition of the participatory nature of reality is probably right. But he differs with Wheeler on one crucial point. Linde believes that conscious observers are an essential component of the universe and cannot be replaced by inanimate objects.

"The universe and the observer exist as a pair," Linde says. "You can say that the universe is there only when there is an observer who can say, Yes, I see the universe there. These small words — it looks like it was here— for practical purposes it may not matter much, but for me as a human being, I do not know any sense in which I could claim that the universe is here in the absence of observers. We are together, the universe and us. The moment you say that the universe exists without any observers, I cannot make any sense out of that. I cannot imagine a consistent theory of everything that ignores consciousness. A recording device cannot play the role of an observer, because who will read what is written on this recording device? In order for us to see that something happens, and say to one another that something happens, you need to have a universe, you need to have a recording device, and you need to have us. It's not enough for the information to be stored somewhere, completely inaccessible to anybody. It's necessary for somebody to look at it. You need an observer who looks at the universe. In the absence of observers, our universe is dead.

4) Here’s a recent interview, “Why Explore Consciousness and Cosmos?”:

Our Universe May Exist in a Multiverse, Cosmic Inflation Discovery Suggests

The first direct evidence of cosmic inflation — a period of rapid expansion that occurred a fraction of a second after the Big Bang — also supports the idea that our universe is just one of many out there, some researchers say.

On Monday (March 17), scientists announced new findings that mark the first-ever direct evidence of primordial gravitational waves — ripples in space-time created just after the universe began. If the results are confirmed, they would provide smoking-gun evidence that space-time expanded at many times the speed of light just after the Big Bang 13.8 billion years ago.

The new research also lends credence to the idea of a multiverse. This theory posits that, when the universe grew exponentially in the first tiny fraction of a second after the Big Bang, some parts of space-time expanded more quickly than others. This could have created "bubbles" of space-time that then developed into other universes. The known universe has its own laws of physics, while other universes could have different laws, according to the multiverse concept.

"It's hard to build models of inflation that don't lead to a multiverse," Alan Guth, an MIT theoretical physicist unaffiliated with the new study, said during a news conference Monday. "It's not impossible, so I think there's still certainly research that needs to be done. But most models of inflation do lead to a multiverse, and evidence for inflation will be pushing us in the direction of taking [the idea of a] multiverse seriously."
