can gravity bend sound waves?

At the outermost limits of the ionosphere which extends some one thousand kilometres above the surface of the earth individual atoms are held in position by the gravitational effect of binary electrons with frequencies of or above 150 hertz (that is with small particle orbit diameters of 2000 kilometres or more) held captive by atoms at the surface of the earth.\n\nThe orbit of the small particle of a binary electron with a frequency of 0.3Hz at the earth’s surface is large enough to encompass the moon. The combined attractive force of incalculable numbers of very low frequency binary electrons at the earth’s surface (acting in unison with very low frequency binary electrons at the surfaces of the sun and moon) exert sufficient force to hold the moon in orbit.\n\nThe sun, which is 330,000 times more massive than the earth, exerts enormous gravitational force. The orbit of the small particle of a binary electron with a frequency of 0.001Hz at the surface of the sun will encompass the earth. Colossal numbers of binary electrons within the suns mass exert sufficient influence to hold the earth in orbit.\n\n (Those who take an interest in calculation will notice that the moon is approximately one eightieth of the mass of the earth and therefore too massive to be held in orbit by the earth acting alone. It should be remembered that the moon like the earth is held in solar orbit. The gravitational influence of the earth serves only to modify the shape of the lunar orbit from a simple independent solar orbit to the more complex shape of a planetary satellite).\n\nBinary electrons with frequencies as low as 0.000025Hz at the surface of the sun have just enough influence to hold the remote planet Pluto in orbit. At some point beyond the orbit of Pluto (which has an average orbit of 5.8 billion kilometres from the sun) the small particles of binary electrons, whose large particle remains at the surface of the sun, have insufficient influence to hold matter within the solar system. \n\nIt has already been noted (see Atoms above) that the combined mass of all the planets in the solar system is closely related to the total mass of electrons within the body of the sun. From this it can be inferred that it requires some 1800 binary electrons within the body of the sun to hold one atom in orbit. This appears to be the factor which determines the quantity of matter which can be held in solar orbit. The total mass of matter which can be held in solar orbit cannot exceed the total mass of electrons associated with atoms which form the body of the sun.

YES\n\nSince sound waves are mechanical waves they are influenced by the medium in which they travel. But electromagnetic waves such as light and radio waves remain unafftected.

Hi. It is bent at any height above zero. Look at the horizon from a spacecraft and you'll see this. The bending gets reduced as you approach zero height, at which point it is a flat circle.

NO!  Sound waves are just vibrations until an ear receives it and sends it to a brain that processes it. If no ear receives it before the vibration dissipates then there is no sound.

I don't think anyone has. Some years ago, I read about this topic at a web site called weirdsience.com (or some such thing). The hyposthesis in that article was that wave energy (light, electrons, and so forth) push from all directions. However, only a certain group of wavelengths can fit between a fixed set of points, based on the separation distance. For example, fewer wavelengths can fit between the Earth and the Moon than can fit between either body and the rest of the Universe. Therefore, there are many more waves, hence much more energy, pushing the two bodies towards each other than pushing them apart. On other hand, there is some evidence that gravity is conveyed through a supposed graviton particle. But such a particle has not yet been observed. Short answer, gravity is still one of the major mysteries of physics.

no.\nsound waves travel faster in warm temperatures than in colder ones.\nWhile sound does travel faster in warm air, it doesn't necessarily travel farther. If sound is traveling over a warm area, the temperature normally decreases with increased height, thus the top part of the horizontally traveling sound wave will propagate slower than the lower part. This causes an upward refraction of the sound, bending it away from the ground. However, over a cold area, such as a frozen lake, the upper air may actually be warmer than the lower layer of air. This causes the sound wave to travel faster in the upper region resulting in refraction of the sound towards (along) the ground. And the sound will "travel" farther over the cold surface than over the warm surface.

Yes, speed of sound is "fixed", like the speed of light and does not depend on the frequency\n\nFrequency affects the volume, if it's peak and trough changes. Higher the peak and trough, the louder the sound and vice versa.\n\nFrequency affects the pitch,if it gets higher or lower. Higher the frequency, higher the pitch, lower the frequency lower the pitch.\n\nHowever sound does change speed depending on the medium it's traveling in.  It travels faster in water,I believe.\nAnd it cannot travel in vacum, so it has zero speed in space.

Yes.\n\nBending of light is most easily observed during gravitational lensing, where a dense, distant object bends light sufficiently that you can image an object directly behind it.  In these scenarios, the phase changes exhibited by the light (a distance dependent-phenomenon) are entirely consistent with the smooth, curved path expected from theory, not a sudden sharp change.\n\n[Edit]\n\nAnd in response to your edit - yes.  Light is bent by gravity, even infinitesimally - and since there is mass, and hence gravity, in the universe, light rays are bent - just not noticeably on a local scale!

Sound travels in a wave.  Actually travels best through a solid.

The answer to this depends on if you are a physicist or a biologist! A physicist would say "yes" because to him/her sound is vibration of air molecules which will occur when a tree falls. \n\nA biologist, however would say "no" because sound is a perception in the brains of living things capable of perceiving it. The perception is a brain's interpretation of the nerve signals sent to it as a result of vibrations causing the eardrum to vibrate, then the ossicles in the middle ear, then the fluid in the cochlea, then the hair cells etc. There is no sound until a brain perceives it, only vibrating air.\n\nEven if the vibrations are recorded, there is still no sound until the recording is played and heard/interpreted by a capable brain.

gravity and air resistance.

No...there needs to be a medium for sound to travel through, considering the Big Bang was the beginning, there would be no 'ether' for any sound waves. Just as we cannot hear any of the large energy bursts from the sun which occur everyday.

Sound is a pressure wave. When it hits a surface the pressure wave is sensed as a force wave. Although weight is a force, the force caused by sound is not weight since it is continuously varying about a mean of zero.

no idea....but it could probably be cause all the sound gets sqeezed near the water surface like when you through some dough on the wall...and the ripples combine to increase thier amplitude and hence volume

You have uncovered one of the secrets of the universe. Simple Harmonic Motion (SHM) surrounds us in every aspect of the universe. It is the lowest common denominator. Even Newton got it slightly wrong in his First Law where he said that a body will continue in uniform motion until an external force acts upon it. There is nowhere in the known universe that gravity does not exist.\n\nConsider an air table which is flat and which extends in all directions by a million miles, and it rests on the earth. place a puck on it and give it a gentle nudge. It will move off in the direction you push it at an apparently constant velocity, however it will eventually stop and return to the point where it started because of the earth's gravitational field. It will shoot past and head off in the opposite direction until it stops again, being pulled back by the earth's gravitational field. It will continue this way forever (ignoring all friction), oscillating in simple harmonic motion. \n\nNewton's problem was that he was restricted to observing a very small portion of the SHM path, so it seemed linear.\n\nAnyway, congratulations, you are on the path to unlocking the secrets of the universe.

yup you are right. The force requires matter. Like a tree in the forest falling. Sound waves are created but if no one hears it does it really exist?

No, i dont think gravity can pull in multiple directions, which would be neccessary for something to expand.
