The "tooth radios" must be electro-mechanical because if I remember right they heard the sound coming from their jaw.

Look for something that solidified very fast, at the speed of sound.

Which ofcourse would mean we couldnt call it emty space any more. But if you took your experiment outside our universe you wouldnt be measuring the space we are familiar with, and isnt our space what you're interested in?

Remember the "ether wind"?

Find a "substance" that ,like you say, hardens, poymerizes, whatever, that gets hit by soundwaves from ONE direction .

Does light in a vacuum slow down , or is it only deflected, when it passes through a strong gravitational field?

If you knew the exact location of every particle of matter in the universe at any given point in time you could conceavably reconstruct the past exactly as it was (an fore-tell the future as well), but it would not be traveling back in time. I dont believe time travel is possible.

Seems to me if anyone or anything went back in time it would have to be in some state other than the matter we currently exist in. Otherwise we would alter history by our presence. Even if we altered the position of only one atom in the past, we wouldnt be viewing the past; only an altered past.

So, what you are meaning is actual velocity of the neural impulses in the brain that constitute rational thought, or I guess any kind of thought? That would be difficult to measure.

Certain people, idiot savants for example, can calculate extensive math problems at incredible speed. Are they consciously "thinking" when they do that? Or is their brain performing on its own, so to speak?

Maybe a standard math problem, simple in nature, could be a relative measure of "thinking speed". For comparitive purposes only.

Is it that multiple sets of DNA can replicate proteins faster in a cell than a single set can? Are polyploidal cells physicaly bigger than normal cells?

Yes it is a test of memory, but the speed in which it can be done with a perfect score (getting all the answers correct) , wouldnt that be an indication of thinking speed?

polyploidy seems like the right approach because the whole plant needs to be larger to produce larger fruit: bigger stems and branches to support higher fruit weight, leaves to make materials faster, etc.

Is fruit the small size they are because anything bigger couldnt mature (produce seed) within the growing period?

A simple test for measuring "thinking speed" could be to read a short story and then answer questions about the story that would involve logic to answer correctly. The testee would not be allowed to review the story after initially reading it. Measure the time it will take to do the test.

Your perfect vacuum wouldnt have any atomic particles, no matter of any kind. But it would not be free of energy waves that would penetrate thru the walls. A stray high energy, sub-atomic particle or maybe a neutrino, could also spoil your experiment?

It would be extremely difficult because atoms would escape off the vessal walls, unless walls could be made from something with a strong atomic structure (diamond) and be absolutly pure. We dont have technology to do this.

Seals of any kind are never absolutely leak free. And they also are part of the vessal walls.

If we could make a chunk of "ideal" material and stretch it so as to cause an internal rupture and then keep stretching it to form an internal void, that void would be a perfect absolute vacuum.

Then, what would you do with it?

I wonder if it's something like imprinting? You know, like what baby ducks do, at the right age it only takes one look. Maybe at the right time for some people, during their youth, that part of the brain can be easily molded to one perclevity or the other; an off-hand remark, a single vivid image, etc. For most of us, our sexuality is too strongly dictated by our gender to be swayed by such minor events.

Wouldnt it be frustrating if you could think the way you do now but do it 10X faster? Remember, you wouldnt be able to move 10X faster, only think faster.

It seems like all organizims, including us, process information at a speed fairly well matched to the physics of its environment. An important part of that environmnt is the animal's own body.

Big animals have big brains that think. Small animals have small brains that, as far as we know, dont think but are very effecient at reacting at lightning speed. Small creatures need to react fast to escape danger or capture quick moving food. We large anmals dont need to react that fast so we can enjoy the luxury of rational thought that requires a large brain.

Seems to me there is a practical limit to fruit size in that the larger it gets the more uneven the ripening process. Imagine an orange the size of a basket ball; the portion that ripens first would possibly spoil before the rest caught up.
