Hořava’s Gravitiation Model

This is looking very promising, the gist is essentially that at extremely high energy levels, relativity undergoes a 'phase change' of sorts that uncouples time and space. The new theory explains several phenomena that already exist, and its predictions seem sound so far. There are some major problems with the equations as is, but it's still interesting nonetheless ^.^

That's pretty exciting, even though I know absolutely nothing about physics :3

Thanks!

hmm, this is getting interesting.
This feels like science at its best, improving itself even more.

if this becomes the prime gravitation theory overshadowing einstein, it will shock the world, but it will be an oppertunity to explain how science works and how it self-corrects itself. there might be a few instance it cant yet describe, but from the article it sounds very promising.

I'd like to see the predictions this model makes about singularities.

Hmmm....

There are a lot of theories that have surprisingly consistent results with known phenomena. String theory gives the same sort of consistency, as well a quantum loop gravity.

Be cautious, however. This theory is consistent with observations but it isn't even the most consistent. The most consistent, testable, and simple unifying theory is formulated by Christoph Schiller, whose "Strand Model" predicts the following:

1) It predicts the exact properties of all discovered elementary particles. Furthermore it predicts the existence of ONLY these elementary particles. (If another elementary particle is added, the theory will be disproven)
2) It predicts that the supposedly illusive Higgs boson is not detected because it does not even exist. (If the Higgs boson is discovered, the theory will be disproven)
3) It predicts that the unitary of scattering for longitudinal W and Z bosons is maintained at all energies (confirmed)
4) It correctly calculates all gauge couplings
5) It correctly calculates all particle masses
6) It correctly calculates all mixing angles
7) All neutrinos possess mass (confirmed)
8) All neutrinos differ from their antiparticles (confirmed)
9) Neutrinoless double beta-decay will not be observed (it hasn't yet and if it does the theory will be disproven)
10) It correctly calculates hadron form factors.
11) Dark matter is predicted by the model
12) It predicts the electric dipole moment of elementary fermions is of the order of the Planck length times the elementary charge. (Confirmed)
13) It predicts there are only three fermion generations. The proton and the positron charge are equal.
14) It predicts that no gauge groups other than those of the standard model exist in particle physics. No form of GUT, technicolour or supersymmetry is valid. No other interaction exists. Protons do not decay.
15) The edge of the universe is a horizon (consistent with accelerating universe)

This theory is inconsistent with nothing and makes falsifiable predictions. However, the predictions need to be set in stone in experiment before I make my conclusion.

Best of luck to Mr. HoÃ…â„¢ava though!
