I have seen several web pages make reference to some theoretical engineering development possible in the future, known as gravitonics, basically they say that as the electron is to electronics, so the graviton will be to gravitonics, claiming all they need is a complete quantum theory of gravity.
As a person not wanting to be duped, I would like to know: is this stuff bunk, crackpotola, or just scifi?
How likely is it that we will see gravitonics within the next century?
What is it about the graviton that makes electronics so much easier than gravitonics? The size of the particle? The difficulty in manipulation? What?
Electrons are relatively easy to pry out of atoms (just stroke a cat on a dry day…) There doesn’t seem to be any comparable means of dragging gravitons (if they even exist!) into a free state where they can be used for heavy lifting.
Gravitons are so small they have not been detected yet. They have mass and are spin 2 particles. Detecting them would be very difficult and way past the technology we have right now. All of this assumes that gravity can be represented by a field theory and that gravity comes in quantum units.
electrons are way bigger and have a much larger interaction with other particles that are sensitive to the electromagentic force.
In short, don’t invest in anything containing the words gravitons in the next few hundred years.

Not if superstring therory is correct (and thus far, we have no reason to suspect it isn’t, yet). According to it, no particles are point particles, though they can generally be fairly accurately modelled as such, for most purposes. In reality, string theory says that particles are either one-dimensional strings or two-dimensional 'branes.
I don’t se how you can make a gravitic circuit like an electric circuit, but perhaps one can utilize the gravitic spectrum for communications and sensor aparatus.
Imagine the implications of the gravitic equivalent of a radio or telescope.
Assuming (and I know it’s a freakin’ Brobdingnagian assumption) that you could generate gravity waves at will, what could you actually do with them? Could you generate artificial gravity or some sort of reactionless* drive?
[sub]*reactionless in the sense of you’re pushing your spaceship forward and the rest of the galaxy backward.[/sub]
I’m aware of them: a set of laser beams bounsing off of mirrors, the two beams set at a 90 deg angle. The entire setup can be kilometers long…kinda bulky, ain’ it?
BTW…any confirmed gravity waves detected yet?
