Big Bang Really a Big Hum 452

Posted by michael from the letdown dept.
benna writes "The New Scientist reports, 'The Big Bang sounded more like a deep hum than a bang, according to an analysis of the radiation left over from the cataclysm. Physicist John Cramer of the University of Washington in Seattle has created audio files of the event which can be played on a PC. "The sound is rather like a large jet plane flying 100 feet above your house in the middle of the night," he says.' Apparently the idea for the project came from an 11 year old."

      The reason you can't hear sound in space is because it's almost a vacuum. Back around the time of the Big Bang, matter was packed much closer together and density was far higher. Much higher, for example, than the density of the Earth's atmosphere. So yes, sound vibrations could propagate around in the early universe.

        But the early universe at the moments they're talking about was crammed into a space less than a quarter the size of a proton. Any vibrations in the primordial soup would have to have a wavelength even smaller than this, and hence a frequency whose value in Hertz would boggle the mind. If it had a wavelength bigger than the size of the universe at the time, then the "sound wave" would destructively interfere with itself.

      It's a hypothesis, just like the Big Bang itself. There's no real way to "prove" it, except inventing a time machine. People don't seem to get what science is all about. No-one can ever be 100% sure of a theory. In the case of the Big Bang:

      1. We observe that things seem to be moving away from eachother pretty rapidly.
      2. We note that if things are moving away from eachother, it's quite likely they all started out in the same place. So we formulate the Big Bang hypothesis.
      3. We go out and look to see if our new hypothesis can predict any interesting things, like star formation or black holes, or whether it fits nicely with other theories like Relativity, for which we already have compelling evidence.
      4. We do experiments to test these predictions. An experiment can also be an observation, in the sense that the entire universe can be viewed as one big continual experiment about which we can record results.

      So, it seems the Big Bang is about the best model we have of universe formation at the current time. So by applying other physics principles we might be able to estimate what it sounded like. True, this is in a sense unprovable, so I agree that we can't really reach step 4, but it's interesting nonetheless.

      Scientists (Personally, I'm just an amateur these days) have great difficulty getting people to understand this distinction. These wackos say things like PROVE EVOLUTION OR I DECLARE IT WRONG!. The point is, you can't prove it, and any scientist will regard such things just as the best model based on some compelling evidnece, but will never put blind faith in it.

        any scientist will regard such things just as the best model based on some compelling evidnece, but will never put blind faith in it.

        There's ample historical evidence to disprove this theory, unfortunately. Many scientists get tied to particular theories and cannot be dissuaded from them. In the face of evidence that appears to contradict their theories, they try to find ways to discredit the evidence or demonstrate through some logical sleight of hand that it does fit their theory. Or sometimes they just ignore it.

        This is because scientists are people and people are imperfect. However, science as a whole is pretty effective at discarding bad theories, even if scientists aren't. It just takes a generation or two.

        It's also important to remember that bad theories, once established, do not die until a theory that is clearly better comes along. Until then, the bad theory is kept, and patched to fit the evidence.

        Science is a fine process for understanding the observable world, but it's a good idea to understand its limitations as well as its strengths. One must be skeptical of skepticism :-)

      Standing outside the universe is not really something you can do. If indeed the universe is bounded, it's most likely not in our traditional three dimensions. Latest research indeed indicates that it just goes on and on looping around on itself (in all three directions, the bending is in higher order dimensions), so if I lift off the Earth in my rocket ship and travel in a straight line in any direction, I will eventually end up back at Earth on the opposite side (or at least where Earth happened to be when I left for my trip).

      Although we have no theories about what might be "outside" the universe, it's pretty impossible to form any theories because we can't see it, we have zero evidence that anything outside the universe exists, and if we did go there, perhaps our physical laws (unique to our universe) may well have no meaning.

      If there is nothingness outside the universe, it does not mean a big black void. Nothingness is not something you can stand around in. Nothingness means NOTHINGNESS, no time, no length, no height, no breadth, no nothing. It doesn't exist. Not existing is not the same as being empty, unfortunately true nothingness is not a concept our human minds can deal with because our monkey ancestors never encountered it in their day-to-day lives.

A spokesman for Atari is reported as stating, "Although this violation appears to be in three dimensions, we beleive it is a close derivative and still covered by the patent." When it was pointed out that the patent was not issued until the late 1900s C.E., Atari responded with, "It may be very well that God created this before we did, but there is no prior art since the evidence did not surface until after our patent was granted. If it were the case that clear evidence was given beforehand, our patent would be invalidated. However, here, the patent holds."

Instead it's space itself that got "stretched" ie. the time for light to reach two distinct points in the universe has increased over the last fifteen billion years. The escape of galaxies works the same way.

Scientists were able to measure the waves by looking at cosmic microwave background (CMB). These early soundwaves are thought to have created super and giant clusters of galaxies with their travel.

      Space itself streched, the matter did not move apart. Think of a ballon with dots on it, as you inflate the balloon, the dots move apart due to the stretching of the medium they are embedded in. There are no constraints that we know of on the speed that space can stretch at.

    This is just taking energy fluctuations and "resampling" and scaling into the narrow band of frequencies (approx. 20Hz-20KHz) that we perceive as sound.

    You can do this with anything--I wouldn't be surprised if some site somewhere lets you "hear" the Sun's recent plasma ejection.

    This is not what you would have heard if you had "been there", folks.

    This kind of pseudo-science is even more useless than the "what color is the universe" articles. I guess people love to be able to relate to hard-to-comprehend things with their senses.

    Nothing to see here, folks, lets just move along and go back to our arguments about whether the universe is shaped like a donut [slashdot.org] or a soccer ball [slashdot.org].

    Here's an ogg format of the sound file:

  • Setting aside for a second all the technical details about no sound in space, and speed of light and such, this is still an interesting concept- but not a new one at all.

    One of my favorite passages in Tolkien's work is his story of the creation in The Silmarillion [amazon.com], where Middle Earth flows from the Music of the Ainur. As somebody else already posted, Aslan of C.S. Lewis's Narnia Chronicles sang Narnia into existence. And many Eastern religions have associated sound with creation. Even in Genesis (and la [crosswalk.com]
  • In one of those strange coincidences between science and mysticism, Buddhists (and perhaps Hindus as well) posit that reality began as sound alone -- the drone of ohm. That sound is the lowest hum that a human can produce -- and if you ever hear a large group of people do it in concert, it will resonate in every cell of your body, physic-ally speaking.

    Not that this clip sounds anything like an ohm. But it's a fun connection all the same.

    For those who may not know, the "AOM" sound that people make when they are meditating (you know, "a-ummmmmmm") is supposedly the sound the universe made when it was created.

    First of all, this sound is based on observations of the microwave background radiation, which didn't come into existence until 300,000 years after the big bang. You will note that the article states "when it [the universe] was just 18 million light years across" Imagine beating a drum that big, and you'll see why the pitch is so low. So the big bang may or may not have been a "bang" but 300,000 years later, the sound made was a hum.

    Really, the relevant signal to listen to is the background signal of gravitational waves. These actually correspond rather directly to (faint) sound waves, since they induce mechanical disturbances as they pass through matter. By now, of course, most of these will have stretched to the dimensions of the universe, and be more or less undetectable, even in principle. Some theories predict the existence of higher frequency waves going back to the first moments of the big bang. We can look forward to detecting some higher frequency waves in the next five to ten years, from the various interferometers [caltech.edu] coming online. This is serious science, and could provide insights into not only the origins of the universe, but also supernovae, and the dynamics of black holes and neutron stars. Not to mention curiosities that may occur unheralded. Something akin to the advent of radio astronomy may be in store for us.

    There's also (presumably) a neutrino background, from about one second after the big bang. This will be very hard to detect, until we build a big sister to AMANDA [uci.edu] covering icy orb, perhaps ganymede :) Some folks seem to be trying to detect it indirectly via the microwave background.

    Physicists are entitled to a little fun now and then, anyway. It also helps to bring cosmology a little closer to the general public. It certainly isn't as if this researcher had to get a peer reviewed grant of many thousands of dollars to produce such "trivial" results: he simply did some starightforward processing on data that was already available, quite possibly in his spare time on his own computer. Oh, and I would definitely classify this as more useful/pertinent then that (admittedly a bit silly) "color of the universe stuff"!

    It is not the case that "any" sound can be created, or that there is no relationship to the original, when scaling by 100,000. Many (most) relationships are preserved in this sort of operation. Indeed, a familiar example would be to speed up or slow down normal speech; it remains understandable.

    Science starts with the presumption of ignorance, and then proceeds to discover what the universe can tell us about itself. Many slashdotters could take a lesson from this.

    The Big Bang was a Troll against catholic physicits pushing a scientifically viable theory to creationism: the primordial egg was proposed by a gesuit priest. Try reading E. J. Lerner's "The big bang never happened", it's a wonderful book and gives pretty sensible explanations to cosmological data; shame that no scientific institution wants to question the enstablishment... perhaps those that run the business built their careers on these theories?

      See this website:

      This is an in-depth analysis of the arguments that Lerner presents in his book.

      Lots of scientists question the Big Bang theory, all the time. Most of them come away with their questions answered by it. Many others come away thinking that there are still questions that science needs to address. A very few come away believing that their questions haven't been adequately answered, or that there is a better answer. It's just that the Big Bang theory is a simple, straightforward theory that happens to describe the observations we see, and does a very good job of explaining a number of disparate observations. Some still disagree with it, and indeed one of them wrote a review article in the latest issue of "Annual Reviews of Astronomy and Astrophysics". They aren't ignored; they just don't have the weight of evidence on their side at the moment!

      There's no conspiracy going on here. Move along.
