Default New Quantum-Gravity theory splits time from space, may explain DarkMatter & Energy

The theory is called "HoYava Gravity". It suggests that at the quantum
level, time is separate from space, but that they mingle together in the
classical scale.

Well, this could be another one of those "Yet Another QG Theories", or
it may be on to something. It seems that QG theories basically fall into
two families, those that think General Relativity is more right, and
those that think Quantum Mechanics is more right. They delineate
themselves by either suggesting time is equivalent to space (GR), or
time is not equivalent to space (QM), and then work the other theory
around it. This one seems to be on the side of time and space are not
equivalent, and tries to work General Relativity around it. Superstring
Theory is another theory that also puts QM ahead of GR in precedence.

The theory also suggests that Dark Energy and Dark Matter pop out from
the gravitational equations in this theory, but they aren't separate
entities. They are just behaviours of good old gravity under different
conditions. There have been other theories that also suggest that Dark
Matter and Dark Energy are the same thing, and that they are just
different aspects of gravity. One such example is Dark Fluid Theory.

Splitting Time from Space—New Quantum Theory Topples Einstein's
Spacetime: Scientific American
"HoYava gravity may also create the “illusion of dark matter,” says
cosmologist Shinji Mukohyama of Tokyo University. In the September
Physical Review D, he explains that in certain circumstances HoYava’s
graviton fluctuates as it interacts with normal matter, making gravity
pull a bit more strongly than expected in general relativity. The effect
could make galaxies appear to contain more matter than can be seen. If
that’s not enough, cosmologist Mu-In Park of Chonbuk National University
in South Korea believes that HoYava gravity may also be behind the
accelerated expansion of the universe, currently attributed to a
mysterious dark energy. One of the leading explanations for its origin
is that empty space contains some intrinsic energy that pushes the
universe outward. This intrinsic energy cannot be accounted for by
general relativity but pops naturally out of the equations of HoYava
gravity, according to Park."

Contemporary physical theory is streaming flop sweat vs. empirical
observation. The simple explanation is that theory is fundamentally
wrong for selectively weak founding postulates. This is testable,

Well, that's been obvious since the days that they found out that QM and
GR were incompatible.
