Just a thought I had...
Parallel to the axis of orbital angular momentum the intensity is tiny.For the common source of gravity waves - inspiralling black holes - are there any directions of space into which gravity waves are not emitted, for reasons of symmetry?
Well, that´s about the hearing threshold for healthy human ear. Wasn´t sure whether it is 0 db or 1 db that is quietest sound which can be heard.1 decibel is an odd value to choose, but whatever.
The 10-21 stretch of gravity waves sounds like a small number, but the 10-12 stretch of 1 db sound also sounds like a small number.we get 10-12 length changes. Most parts of the human are significantly softer and will deform more.
I do not believe it works that way. If you stretch body parts using a force then the rigidity matters. The gravity wave is stretching space time. You would not feel anything. Soft tissues change in exactly the same way that hard tissues change.10-12 is the stretch in bones, everything else will be stretched more, especially the eardrum.
If you ride the vomit comet you perceive micro-gravity through one part of the cycle. At high altitude acceleration of earth's gravity is lower than at low altitude. The distortion of time-space changes but you feel the same micro-gravity. The bicep, humorous bone, and a measuring tape wrapped around the arm are all effected by dilation in the same way. [Tidal forces are different. Might make this example bad]The body parts would expand/shrink to their original size, assuming the frequency is low enough to make that possible. Different body parts would follow at different speed.
https://en.wikipedia.org/wiki/Gravitational_waveLIGO is so long that the mirrors are effectively floating in space relative to each other. Your human body is not (at the frequencies LIGO is interested in).
I am not an expert on this topic. Gravity waves passing through the galaxy would dissipate if energy was doing work on the molecules in objects.
Gravitational waves - gravity waves are something different.Gravity waves passing through the galaxy would dissipate if energy was doing work on the molecules in objects.
If a 1 meter iron bar is clamped and tightened to 0.99 meters it is under stress. If the length of the space in the clamp and length of the iron bar are equal before, during, and after an event then there was no stress.If the distances within a solid object decrease in one direction and increase in another, it induces stress in the object.
The difference between 10^-12 and 10-21 is a billion to one, so assuming things being equal, the gravity wave would have to be at least one billion times stronger to be heard. I think if you actually were close enough to say a binary black hole to hear it you would be in deep doo doo.Well, that´s about the hearing threshold for healthy human ear. Wasn´t sure whether it is 0 db or 1 db that is quietest sound which can be heard.
The 10-21 stretch of gravity waves sounds like a small number, but the 10-12 stretch of 1 db sound also sounds like a small number.
Certainly 1 db sound at 250 Hz does not feel like "being pushed/pulled" - it is felt by ears alone.
So could sufficiently strong gravitational waves be perceived directly by naked ear as a quiet sound?
