Is artificial gravity impossible?

[metavac]

Uh, no. It will not gain mass. If anything, it'll lose mass as it bleeds off into the eviroment, and even that's going to be undetectable.

Hence, I noted this works only if the object is kept at a constant volume.

Does a hot light bulb way more than a cool one?

Because a hot bulb radiates into its environment. It's losing mass.

No. Mass doesn't come out of nowhere.

No, it doesn't. It's conserved; the additional mass is do to the heat into the system.

Heating will make it's volume and surface area increase.

Hence, I said "constant volume."

How do you plan to do this?

Well, you did say something about heating the object...

And how do you plan on getting enough extra mass into the system? It takes an enormous amount of energy (of whatever sort you please) to make even one gram of mass. Remember, E=MC^2? .001 x C^2 is still a huge fucking number. I'll calculate it, if you like.

Heating will make it's volume and surface area increase.

Hence, I said "constant volume."

And I would like to know how you'll manage to keep the volume constant. Because the amount of energy you'll need to dump in to make enough mass to do jack shit is going to bleed off into any surounding materials, no matter how high their specific heat capacity.

How do you plan to do this?

I don't. But if I did, I'd increase the pressure in the surrounding environment accordingly.

Well, you did say something about heating the object...

Yes, I did. What about it?

Short answer is I don't. Hence, "it does not avail you of accounting for the masses and distances necessary to generate a desired surface gravity and its gradient." You'll need to pump up the internal energy of the system by 10^16 J to get an additional kilogram of mass.

Heating will make it's volume and surface area increase.

Not in an isometric process. Remember, the relation is PV = U, where U is the internal energy of the system, P is it's internal pressure, and V is its volume. It's easy to show that you can vary P independently of V.

And I would like to know how you'll manage to keep the volume constant.

By applying pressure externally or choosing a material with a high enough tensile strength to resist expanding at that temperature.

Because the amount of energy you'll need to dump in to make enough mass to do jack shit is going to bleed off into any surounding materials, no matter how high their specific heat capacity.

Undoubtedly, but the point of this whole exercise was to show how absurd a magical electricity to mass converter is. Like you pointed out, the whole setup consumes a whole lot of electrical power. And in the end, you have the same amount of mass you'd find classically for the desired surface gravity and gradient.

A question: If the Higgs particle is so-called if I recall correctly responsible for mass, what are the interactions between the Higgs and the theoretical graviton that cause matter to have mass and exert gravitation force?

Gravitons, provided they exist, have nothing to do with it--like photons, they're massless. The Higgs boson imparts mass to the massive elementary particles as it approaches a vacuum state because. A field coupling both descriptions of the interesting particle and Higgs boson has minima that resembles the bottom of a wine bottle (with a circular bump in the middle). This means that the coupled field can oscillate radially (around and around the valley) and longitudinally (up and down the slope of the hill and the bottle's wall). The longitudinal oscillation gives the potential associated with the particles rest mass. The radial oscillation gives the potential associated wit the particles wave momentum. Gravitons and photons, as you might've guessed, do not bob up and down in the valley and are therefore massless.
