Also,
If we involve wave forms into a description of the result of a sudden change of a mass's affect on space(as in the very question of this topic), then we must also include time. yes or no?
How can we describe a shift or rebound of space as a wave with out a frequency? That requires time.
So gravity's affect or lack of affect, on space and object ...[text shortened]... ing in the dark.
But I use a full-auto shotgun! What a scatter brain!
OMG I can't see!!!...
You know how you have a bedspring, a lot of springs holding stuff
together and there is an inherent springiness to it, you can pull it
apart and it springs back to its regular shape and if you squeeze it
it comes back to normal when you let go. Same thing with space,
only a bit more complicated🙂
When you add mass to bare space, its like the old trick of the
stainless steel bearing on a rubber sheet, which bends down to
give you a two dimensional visualization of what space is doing when
mass is added. Its really more like a bunch of springs in a mattress
where you have this matrix of springs in all directions and now instead
of gravity you put a strong spherical magnet inside that matrix of
steel springs. The magnetic field attracts the springs which stretches
them out a bit but in all directions. That is just another way of
visualizing the effect of mass on space and time. Time squeezes
also and a gravity wave is a small squeeze in time and a small
squeeze and pull in space at the same time so there is a definite
wavelength and we are trying to sense wavelengths on the order of
a few hundred miles long which is what you might expect if you have
two neutron stars orbiting one another, the system will produce gravity
waves of about 1000 Hertz and that is a wavelength of 186 miles.
Thats what the LIGO and others are hoping to be tuned to. If you
have the space system working you might see much longer
wavelengths because the satellite system would have three boxes
in a triangle about 4 or 5 million Km apart and the beams would go
from one to the other and be able to tell the distance between the
three pieces of less than a micron, this would be tuning for longer
wavelengths, maybe 50 hertz, or a wavelength of about 3700 miles,
maybe even longer.
