There are probably duplicates/variants of this question on this site. Expressing the problem in mass terms seems a bit odd to me though, as it's been put in energy terms every other time I have seen it asked, unless I have misunderstood your question. Here is an answer (to an identically worded question) based on the link: Predicted Mass of Quantum Vacuum ...

The cosmological constant of classical General Relativity and the vacuum (or zero-point) energy are closely related. The cosmological constant is simply a constant term $\Lambda$ in the Lagrangian density for the Einstein-Hilbert action and may be interpreted as an energy density permeating all space. In quantum field theory, one finds that the vacuum can, ...

This won't work, though possibly not for the reason you think. High energy protons will go straight through a turbine blade without transferring any significant amount of momentum to it. The LHC uses a seven metre long block of graphite to catch the proton beam if there's a beam dump. Steel has greater stopping power than carbon, but even so a turbine blade ...

Well there is no reason of why it would not . But really what is the purpose of putting a turbine inside a particle accelerator.That beats the purpose of the accelerator to work without much resistance.If it is to generate energy or something, I doubt it's a viable solution.hydrogen as a gas is very hard to compress so I don't think you can make a solar ...

If the cube is sealed, doesn't expand and the temperature doesn't change, the pressure inside the cube will remain at 14.7 psi. That pressure is applied to all 6 sides continuously, simultaneously. Pressure in a sealed container will depend only on the volume and the temperature, not the number of sides, nor the external pressure. On the other hand, there ...

Sometimes I feel Wikipedia is a funny place... In the article you quote they provide a calculation from our patent application (see, e.g., http://akhmeteli.org/wp-content/uploads/2011/08/vacuum_balloons_cip.pdf ) proving that a homogeneous shell made of any existing material cannot be both light enough to float in air and strong enough to withstand ...

Nobody knows. There are multiple explanations for dark energy that haven't been eliminated. One of the explanations that hasn't been eliminated is zero point energy: http://arxiv.org/abs/1205.3365. Another possible explanation is that the alleged expansion is actually a result of neglecting the effects of inhomogeneities on averaging: ...

A spinning top is a gyroscope; it doesn't need air. The gyroscopes on the Hubble telescope work just fine up there.

I was just looking up your level of education in order to gauge my further replies. I bumped into this, and whilst it's an old question, but I felt moved to answer it. My understanding is that a photon propagating in vacuum has a small probability to spontaneously create a particle/antiparticle pair that will then quickly recombine to emit a photon ...

I'm not so sure about the atom trap though. But I do have a cheaper alternative for your flexible plastic membrane: You can transfer Rotation Force into your "clean" chamber with the use of Magnet. This can be done by attaching a Magnet outside the chamber and another Inside the Chamber. Rotating the Outer Magnet will rotate the Inner Magnet. Depends on ...

Here I constructed perturbation-like approximants converging to the vacuum in $\phi^4_2g(x)$ (technically an interacting QFT, although not translation invariant, so Haag's theorem does not apply). There are no "infinities" in this case.

Physical things (solid, liquid, gas, plasma) both absorb and emit energy in the form of electromagnetic radiation of a wide range of frequencies. How fast they radiate and the strongest frequencies of radiation depend on the absolute temperature. How fast they absorb depends on the temperatures of objects around them. Therefore, the net intensity (energy per ...
