Time, not space plus time, might be the single fundamental property in which all physical phenomena occur, according to a new theory by a University of Alaska Fairbanks scientist.
Time, according to Kant is the a priori condition of all inner experience. [1] I find that a more useful model, though your mileage may vary because giving up all those ding an sich's doesn't come for free. TANSTAAFL.
[1]: and space the a priori condition of all external experience.

According to the published paper (linked in the article) Kletetschka's theory correctly predicts several experimentally measured quantities of the Standard Model. The two that jumped out at me were:
1) the weak mixing angle
2) the three particle generations and the ratio of their masses

I think it makes no sense, but as HN discourage swallow dismissal ...
* I can't find the part about "with space as a secondary effect". Where is it? The paper just start defining everything in a space with 3 timelike and 3 spacelike dimensions.
* The easiness to test prediction is the the ratio of the masses of the three generations of particles. The paper claim they are
m_n = m_0 exp(-α n^γ)
Then then claim something like: "1 : 4.5 : 21.0"
The formula has 3 constants to predict 3 constants. So it's possible to adjust them for each family of 3 particles. It's not clear how the constants are calculated and which constants are shared between the different families of particles.
- top/charm/up quarks: the ratios are 1 : 588 : 80186 Note that the mass of the up quarks is much smaller then 1/3 of the mass of the proton or neutron. That's standard. https://en.wikipedia.org/wiki/Up_quark#Mass These masses are very difficult to measure experimentally. The article claims 2.16 ± 0.49 MeV but from Wikipedia:
> Despite being extremely common, the bare mass of the up quark is not well determined, but probably lies between 1.8 and 3.0 MeV/c2. Lattice QCD calculations give a more precise value: 2.01±0.14 MeV/c2.
- bottom/strange/down quarks: missing(?!)
- electron/muon/tau: 1 : 206 : 3477 These values have a extremely high experimental precision. The article claims 0.5109989461 ± 0.0000000031 MeV but Wikipedia says 0.51099895069(16) MeV/c^2
- neutrinos: From the article:
> For neutrinos, this work predicts masses of 0.058 ± 0.004 eV for ν
3; 0:0086 ± 0:0003 eV for ν2, and 0:0023 ± 0:0002 eV for ν1, with mass ratios showing remarkable precision: m2/m1 = 4.5 ± 0.3 and m3/m1 = 21.0 ± 1.5.
But from the experiments we have only upper bounds of the masses. We know they have mass, but we don't know even an approximation of the value. From https://en.wikipedia.org/wiki/Neutrino#Flavor,_mass,_and_the... the experimental values are "<0.08x10-6", "<0.17" and "<18.2" so I don't understand how the paper claims "remarkable precision"
