Sound is only possible because of air right? So what if we blew a foghorn in the vacuum of space, no sound right? So, what happens to the energy of the rapid motion in such a scenario as to blow a foghorn in the vacuum of space? Because there is no air around for it to interact with, doesn't mean it's not there. What happens to it? Does it dis-burst into space? Also, breaking the sound barrier, that sonic boom from supersonic flight. Does different atmospheres have different sound barriers? When two black holes collide and we observe this from Earth and translate that into an audio sound, how do we do that, what the science behind it? Shine up a beam to measure and translate movement into decibels to recreate a sonic boom for our ears?
The energy to move the foghorn's diaphragm is consumed by its vibrations. There are no atoms of atmosphere for that movement to propagate into sound waves. Different composition and temperature mitigates the speed of sound. The speed of sound on earth is calculated at a temperature of 68F. "Hearing" a black hole colliding with another isn't "hearing" in the conventional sense. Its the translation of measured radiation that humans translate into sound we can hear thru technology. Just like "seeing" a broken bone in an xray is the result of the passage of those rays thru the body onto a reactive medium that is then processed into a viable image.
Sound travels in all media: Water, air, metal, jello, plasmas.... some are much better conductors of sound than others. And sound travels at different speeds in each. Sound is merely a periodic pressure wave in the media through which it travels. You have a slightly higher pressure region followed by slightly lower pressure region, followed by a higher-pressure region, and so on. In solids, it manifest as very small stresses in the material. If you supplied the horn with a pressurized air tank to operate, the pressurized air would continue to travel in the direction it was traveling when it left the horn. If you had a microphone mounted in the right location, like right in front of the horn, you would be able to measure the pressure variations, which is what a microphone does. It converts mechanical energy to electrical energy. Yes, the speed of sound varies according to the characteristics of the gases involved, which is represented by something called the isentropic bulk modulus, and the density.
Sound is broken pressures produced from disturbing the source? Waves produced from energy resonating from movement and frictions? What happens to sound wave energy in a vacuum? There is no sound, making for an in audible reaction. But Microphones pick this up regardless and translate energy electronically for us?
Sound is a pressure wave. Watch a speaker operate. It moves very slightly forwards and backwards. When it moves forwards, it compresses the air in front of it. When it moves backwards, it rarefies, or creates a slight negative pressure in the air in front of it. The pressure is varying very slightly above and below the ambient air pressure. This makes your ear drum or a microphone resonate in response to the pressure variations. This motion is then converted to electrical energy that we perceive as sound. .
Sound has energy in the form of pressure or stress, depending on if it is traveling through a solid, or a gas or liquid. In air, it has energy as pressure. And you know it has energy because it causes a microphone membrane to move mechanically. This requires energy.
These sounds like the effects on sound. It's these that change its speed which change its dynamic. But what is 'it'? We all know light is photons, what is sound? What is 'it' that bursts from source?
There is no sound in the vacuum of space because there's nothing for it to react with, but that doesn't say this force isn't happening, it just says there's nothing for it to hit, interact and crash into, so 'there is no sound' made. But that force is still being produced, no? What is it that makes sound travel?
If you supply your foghorn with compressed air, as I already explained, it would cause a microphone to respond if it was positioned properly. That is sound. If you didn't supply air to the foghorn, it wouldn't produce any sound.
In a normal atmosphere, the pressure waves diverge quickly and spread out. This is modeled or predicted in something called the Law of Equipartitions. In space, the pressure wave would travel in a straight line. It would not tend to diverge quickly as sound does in air. So you could hear the foghorn if you were right in front of it, but perhaps not if just off to the side of it.
If a tree falls in the forest and no one is there to hear it, does it make a sound? A pressure wave will travel through the air whether anyone is there to hear it or not. But then again, Quantum Mechanics suggests that without an observer, the tree fell and it didn't fall.
To some degree sound = vibration. To a significant degree = we are vibrational beings...... therefore... to some degree......we are sound??? I have thought of LIGHT as the manifestation of Super Strings in four dimensional space - time and I have thought that SOUND = the manifestation of Super Waves and / or Super Energetic Matter in four dimensional space - time...... but that may be significantly in error...... http://www.allaboutchristian.com/spirituality/ There are some neat quotations on String Theroy and on Wave Theory in this blog if you have the free time: www.CarbonBias.blogspot.ca/ and..... http://www.allaboutchristian.com/spirituality/index.html
It's total nonsense. PS. Some half-baked idea isn't a theory. Theories require a correct prediction no other theory makes. It requires publication, duplication by many scientists, and time to allow for alternative explanations and debunking. And in subjects like physics, it must be a mathematical prediction based on physical laws.
Actually......... the case that can be made that Intelligence began in fundamental or nearly fundamental energy an eternity in the past...... far, far, far, far, far, far more than merely 13.72 billion years or so ago is overpowering...... if it is understood. www.CarbonBias.blogspot.ca/ Theistic Evolutionary Theory I am really impressed with the gang on this forum... only forty one percent of them got this incorrect in my opinion..... Where did Intelligence begin, in matter or fundamental energy? The first Intelligence began in.....? Carbon based life less than 5 billion years ago, on earth. 7 vote(s) 41.2% Carbon based life in outer space. 3 vote(s) 17.6% * Fundamental or nearly fundamental energy. 6 vote(s) 35.3% This is a new question that I am only now facing. 1 vote(s) 5.9% and for the record...... with humanity facing a 710 trillion dollar crisis in the worldwide Derivatives market....... means that reevaluating human life to have something like INFINITE VALUE to an infinitely ancient Creator YHWH the Father and YHWh the Mother / the Shekina Glory of G-d / The Holy Spirit / The Comforter of Christian thought..... is one of the only ways to begin to divert those 710 trillion dollars in Derivatives to be diverted in a win - win - win - win - win manner. FORGET IRAN, IRAQ, UKRAINE THIS IS WHERE WWIII STARTS... There is an answer to all this though..... http://www.politicalforum.com/index...illion-dollar-problem.525406/#post-1068713597
Sound would just disperse in space, as there would be no molecules for the sound to move through. Kind of like when visible light hits a solid black object. Yes, different atmospheres have different sound barriers (as do different materials). The speed of sound, for example, varies between the high part of the atmosphere and sea level (this is due both to atmospheric pressure and temperature, with high altitudes having lower atmospheric pressure and temperature). At sea level, the speed of sound is about 761 mph. At 30,000 feet, it's 678 mph. It also varies some with other parameters like temperature. https://www.engineersedge.com/physics/speed_of_sound_13241.htm The speed of sound also varies between substances--it's much higher in water than it is in air. From what I've read on the black hole thing, the sound is not really sound, it's gravity waves and they have found a way to convert gravity wave energy into sound wave energy on a computer. https://www.newsweek.com/black-holes-gravitational-wave-universe-883535
Sound is not sound until it is heard, it is only pressure variations. It is the brain that converts those pressure variations into sound.
Well, sort of. those pressure variations can be measured by instruments, so it does exist if not heard.
But, it's not really 'sound', unless it's heard, is it? Can an instrument 'hear', or does it just measure?
