  1. Similar effect allows bacteria to withstand much higher osmotic pressures than eukaryotic cells. In this case, it is the line-square rather than the square-cube law. When you decrease the size by a factor, the ability of a membrane to withstand tear decreases by that factor while the tearing force decreases by the factor squared. Thus, a bacterium that is 100 times smaller than a regular cell can withstand 100 times higher osmotic pressure.
  2. Spacetime curvature is associated with radiation. The latter does not have mass.
  3. None of this *** has anything to do with quantum theory or the science of physics.
  4. What they are is described by specific QFT theories. Generally, field is an entity that pervades space and time and is defined by its properties such as spin. "How they were created" goes back to the dawn of the universe.
  5. It was not. It is rather the other way around. Photons are quantum excitations of EM field. The QED and other QFT theories describe interactions of fields. (QFT = Quantum Field Theory.)
  6. Does the QFT provide a sufficient answer? It does not. Not in QED, the best current theory.
  7. How your questions are different from ordinary or conventional approach to behavior of objects under gravity?
  8. Make it short. Embed figures. Use LaTeX for formulas.
  9. The law of gravity is known. Try to answer your questions by applying it.
  10. From the "Guidelines": ... members should be able to participate in the discussion without clicking any links ... ... Attached documents should be for support material only; material for discussion must be posted. ... ... Keep alternative science and your own personal conjecture to the appropriate forum (Speculations). ... See Guidelines - Science Forums.
  11. As I have mentioned, there are many ways. One of them is that the multiverse's space is not necessarily three dimensional. If its geometry is not Euclidean, for example.
  12. On the scale of several hundred megaparsec and more the visible universe is homogeneous and isotropic. It means that on that scale it is the same in all directions.
  13. As the bodies outside our visible universe make pretty much spherically symmetric shell, their gravitational effect inside the shell is identically zero.
  14. Even without water issues, the growing roots of Ficus tree in my yard have killed over the years surrounding coco palms, one by one.
  15. It is curious that the same mechanism gives both the attractive effect of dark matter and the repulsive effect of dark energy.
  16. The hypotheses above may be complementary rather than contrasting because they seem to relate to different aspects of the "four why's of animal behavior" of Nikolaas (Niko) Tinbergen, i.e., causation, development, adaptation, and phylogeny.
  17. What does it mean? The model tells us how it happens. Some future model might derive this model, i.e., the equations, from more generic principles. The previous model, aka Newtonian gravity, included a notion of mass acting on the ship. This is an approximation, which is not included in the current best model.
