    I've always believed that sound can travel through space given how that it's easier to send soundwaves through the air than through a concrete wall. The so called "scientific" dictation that says soundwaves can't travel through space is an international lie designed to discourage conscious mind to conscious mind communication.

    I thought we only had the ICOSSTSTLOE
    (international conspiracy of satanic scientists to spread the lie of evolution)
    was i ever wrong.

    An email to the League of Nations elicited only this:

    "We are unaware of the existence of this conspiracy, no more than of the so called 'South African gold fields' also so much lately in the news."

    Proof enough of collusion!

    Sounds travels far better thro water or iron than air btw. Even a string; try two tin cans and a string some time.

    Since the very definition of sound is that of energy propagated through a medium, how can you have sound in space if space has no definite medium? Regions of space do have a very diffuse medium such as the solar wind, but it is sporradic and not dense enough for individual atoms to come into direct contact and transfer their kinetic energy in any coherent fashion that would resemble a directional wave. Sound is simply energy propagation by creating medium density regions. For that to happen in a coherent fashion you need a medium which is consistent in density and mass of constituent atomic particles.

    The definition of sound should be changed to: audible energy waveforms (or theoretically audible if no belief/entity is in proximity to said theorized audible energy waveforms) through any measureable deity and/or object.

    no medium = no sound.

    If a tree falls in a complete vacuum will someone hear it? (yes we are pretending someone is also in that complete vacuum and yes we are pretending there is such a thing as a complete vacuum)

    Aha! But the OP's article suggests there is a medium in the interstellar space which was suspected, but unexpectedly it is 40 times denser than the heliosphere, which I haven't picked up before having not read the article. But is 40 times dense enough? To create sound you need not only a medium, but medium dense enough for energy to be carried through it in a form of longitudinal pressure/density waves. If a medium is too diffuse, the individual molecules which carry the kinetic energy of the sound will not collide with other medium molecules next to them, but will bypass them and travel some distance unobstructed before finally colliding (or rather coming within range where the electric fields of the electrons or ions can repulsively interact with much significance). In such a case, the density wave will quickly lose its cohesion and diffuse, as it is not given whether the medium molecule will next interact electrically with other medium molecules close or far from it. In a dense medium, molecules always find some nearby molecule to interact with instantenously. So as soon as they gain the kinetic energy, they transfer it.

    Has anyone tried to pick up the audible sounds from an earthquake? Would be curious to know how sound travels in the medium of the Earth?

    Can we detect sounds generated within our own solar system?

    The other issue with the OP is that sound travels slowly so even with the plasma medium how is it possible for sound to travel interstellar distances? It's hard enough to grasp time in light-years much less time at the speed of sound...

    And obviously the comparison was not made between the interstellar space and the heliosphere which is vast and ranges in densities, but rather and more accurately between the interstellar space and the heliopause.

    if a tree fell in a container that had no atmosphere, the only way to hear it would be by placing one's ear against the structure that it fell upon.

    Of course sound travels through space. Indeed, it travels so efficiently through the space between some people's ears that it escapes notice altogether.

    The sounds seem to have been associated with plasma waves. Seems pretty obvious to me that the wave worked as the medium when the sounds were heard. doesn't mean that anyone not inside the wave could have heard anything (assuming that were theoretically possible).

    If you watch the video on the OPs link, it is clear that there is a medium, a piece of the sun that got blown off and finally caught up to Voyager just outside the solar system. So it's not so much "the sound of interstellar space". It's more like "the sound of the Sun".

    Just to be clear....SOUND as Human's perceive it is the Kinetic transfer of a shock wave through matter...no matter...no sound.

    Thus in a vacuum of space there does not exist an atmosphere or nearly enough particles of Matter to allow such a Kinetic Shock Wave to travel.

    If the shockwave from the solar flare caused the ionized gas particles to vibrate, that does not tell entirely if this vibration is due to kinetic forces, or simply absorption of radiation which also excites particles and makes them vibrate. Also, vibration is not an absolute proof of high and low density waves.

    Well, that's getting pretty technical. It seems to me that if you can hear it, then it's sound. So, according to what "sound" means to me, the only question I have is if the instrument that Voyager used to detect this "sound" could be detecting something which the human ear would not.

    All right, well, if the observation was made with a wave detector then the plasma gas does pass the sound test. But according to another report found on the JPL website it was only found that plasma gas constituents vibrated once contact with the flare shockwave was made. But if all doubts can be removed, this should be a sound discovery.

    And you are correct, sound does travel through space. Good for you! Excellent deduction skills. :thumbsup:

    And, in fact, the atoms themselves produce sounds in the form of radio waves. Listening to these sounds, the sounds of the Hydrogen atom, with our radio telescopes even let us map the Milky Way Galaxy for the first time in recent years, and that's when we discovered that our Galaxy is a Barred, Spiral Galaxy (there are bars extending out from the galactic center a ways before becoming a spiral) as previously we just thought our galaxy had a spiral all the way in to the center.

    Look up Hydrogen Map of the Milky Way if you want to find out more... And see what our galaxy looks like.


    Back to the subject of soundwaves, now, you were thinking of the saying: "In space no one can hear you scream." Or, something like that, yes? But, now there isn't a lie... You won't be able to hear someone scream in space with your ears.

    That's why we have special equipment to hear things in space. The problem with space is that everything is spread out a lot more, and if you take any cubic area, a box-like shape of space and check out what's there you'll will find MUCH less sound transmitting matter in there than here on Earth with our dense atmosphere. Our ears aren't designed for hearing sound in such conditions.

    Yes there are audio files of earthquakes. Not all of them make the transfer from listening station to the public, but the recent Japanese earthquake was infamous enough, and enough of an event in the public consciousness, that audio was released to the public.

    Listen: Listening to the 9.0-Magnitude Japanese Earthquake.


    Likewise, you can probably find a few sound clips of the solar system from a search engine. Try looking for one of the Sun or a Gas Giant as those would probably have interesting sounds, I don't know though because I never thought to look for sounds of space before.

    I didn't see on that website where they explain how they achieved the earthquake sounds? The USGS has earthquake 'sounds' but they aren't real sounds but instead they shake a speaker at the same rate as the earthquake to 'produce' sounds...

    Uhhh...not exactly Wga.

    In order to hear the Electromagnetic Broadcasts of such Atoms in our Universe such as the Background Microwave Radiation Field....we must first use a RADIO RECEIVER and then use a SPEAKER to hear this reproduced sound of what this Radiation creates when received.

    It really is not SOUND traveling through space it is Radio Waves just as are a broadcasted TV signal and your favorite Radio Station you listen to in the car.
