Energy cannot be created nor destroyed.  Where does sound energy go in the room like when we speak?

it gets absorbed by your surroundings.

Nothing is nothing. Energy is something.\n\nIf there is nothing in a universe then is it even a universe?  No, it is not, it's nothing.

According to the Masters, Yes.\n\nCurious as to why you would ask this question.\n\nA sound is also an energetic field.  All energy affects the whole of the human being.

Sound relies upoon matter to convey its energy, and it takes time for the matter particles to "bump" into eachother to transport the sound energy, even in a solid. Remember sound is a compression or longitudinal wave.\n\nLight does not rely upon any medium to convey it, so no matter needs to move at all.

LOL I like Mainworry's answer...not!\nCreate anything living without using matter that already exists.\nHe's right, I can't we all can't.... yet!\nBut maybe we will Create matter, out of energy one day.\nThen what will he say.\nBut I know something I can create right now...GOD.\nYes I can create GOD In my own image.

static energy at birth and cosmic energy at death(energy can neither be created or destroy,but can change from one form to another)

Energy is not "lost" it is converted to a form that cannot be used.\n\nDrop a ball from a certain height and the ball does not bounce back to the original height...that is because some of the energy was converted to sound (you hear the ball hitting the floor)...some was converted to heat (the ball and the spot on the floor where it hit are just a teeny bit warmer)\n\nFor the most part you can observe this "lost" energy (usually they are in the form of heat, light or sound)

First Law of Thermodynamics: Energy can be changed from one form to another, but it cannot be created or destroyed. \n\n"You can't win."  Because you can never get more energy than you start with.\n\nThe Second Law of Thermodynamics states that "in all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state." \n\n"You can't break even."  Because you lose potential energy.  It changes to heat.

Sound is a compressional wave and it requires atoms to make energy travel through. think of a pool stick being your mouth. being on earth is the same as having pool balls in front of it therefor the nergy is transferred. however in space, think of your pool stick without any pool balls in front of your stick. nothing happens. becuase there is nothing to transfer the energy. the medium is the matter that carries the sound waves.\n\nLight is a very special wave. it has tiny particles called photons that are infinity small(meaning we can't measure them but we know they are there becuase they ionize special elements.) so light is really a combination of energy and matter. and since light has a medium(tiny particles) within itself it doesn't need any other matter to travel. it can change mediums however, light travels faster in less dense areas than more dense areas which explains that is has tiny particles. sound is just a compressional wave which means when the matter is more dense it travels faster becuase the time required to travel is less becuase the molecules are closer. since light has its own molecules it can't travel through dense matter becuase the dense molecules block the light's particles from traveling.

As long as we understand, energy can take different forms but it can not be destroyed.  It can be converted to mass, and vice-versa.  There are other forms of energy such as light energy, chemical energy.  It seems that energy is exhibiting higher dimensions of space and what we see within our 3D world is translated to our braind as energy.

Who said it is not freely available? Only thing is:-All the energies are governed by the Law of Conservation of Energy. According to this Law, the total available energy is constant, and energy can neither be created, nor destroyed, but one form of energy can be converted to another form. The cost involved in energy is the cost incurred in converting one form of energy into another form.

1. Energy cannot be created or destroyed only changed in form. 2. The total energy of any closed system is = 0\n\nA static generator does not create energy it only changes its form from mechanical to electrical.  Search on the web for perpetual motion for a more in depth explanation.\nalso search thermodynamics, first and second laws.

Energy can neither be created nor destroyed but one form of energy can be changed to other form.

Ernie... I love this question..  it rocks.\n\nThe answer, however, is going to be just a little dissappointing.\n\nAs I'm sure you know, all light is both a particle and a wave; it is a form of nearly pure energy.  As we know from theoretical physics, energy can never be created, nor can it be destroyed.  It just changes forms.  According to the third law of thermodynamics, energy always goes from higher to lower forms when left on its own, the lowest form of energy often being considered to be heat.  And that's where your wandering, amazing laserlight goes, it turns to heat.  \n\nWhy?\n\nBecause your room of mirrors is completely imperfect.  Your mirrors are dismally inefficient reflectors of light, and the room is full of air.  Household mirrors actually reflect less than 25% of the light energy that shines on them back to you.  Lab quality mirrors made for laser work are, I believe, in the high 80% to low 90% reflectivity efficiency range.  Every time your beam hits a mirror surface and bounces off, it looses more of its energy to heat..  just as it does as it passes thrugh every atom and molicule that makes up the air in the room as well.  Your laser might make it one or two 'miles' of beam length in the room before it is bouncing around.. which would make for thousands of beams.  But, since light travels at 186,000 miles per second, your two mile beam lasts 1/93,000th of a second after you turn the power off before it's gone.  So, it DOES keep going.. but not long enough for you to percieve it.\n\nSo, IF you had perfect mirrors, IN a perfect sphere (remember; you couldn't have any corners!) a COMPLETE vacium inside it with NO particles of dust of ANY kind, and a way to fire the beam into the amazing sphere without leaving any void for energy to escape...  your theory would work, if all that were PERFECT.  But; the biggest catch would be; you could never know if it were working!  Because to find out; you would have to have a void in the sphere to see or measure it...  and measuring any energy source draws energy from it.. so, there goes your light again.\n\nSo, that's why, but it's still a great question.  Theoretical Physics is full of stuff like that...  and thinking about it will turn your brain into silly putty for days.  Keep 'em coming, Ernie..  you've got a great future if you keep your mind working like that.

I would say NO... at certain point, particles are made of energy, and energy can't be splitted as matter does...

while it is true that sound cannot travel thru space as such, since there is no tangible medium for it to travel, it is incorrect to state the reason of "space is a vacuum" as it is not, there is normally at least 1 particle per cubic metre, which is not dense enough to allow the propogation of a pressure wave, ie sound.

light cannot directly produce sound, but audible sound can be produced as a result of the rapid heating and expansion of the surrounding air of a powerful light beam.\nan example of this is thunder and lightning.
