In the model of low-energy quantum gravity by the author, cosmological
redshifts are caused by interactions of photons with gravitons.
Non-forehead collisions with gravitons will lead to an additional relaxation
of any photonic flux. It gives a possibility of another interpretation
of supernovae 1a data. Every massive body would be decelerated
due to collisions with gravitons that may be connected with the Pioneer
10 anomaly. This mechanism needs graviton pairing and "an
atomic structure" of matter for working it. Also an existence of black
holes contradicts to the equivalence principle: any black hole should
have a gravitational mass to be much bigger - about three orders - than
an inertial one.

The property of asymptotic freedom of the model of low-energy
quantum gravity by the author leads to the unexpected consequence:
if a black hole arises due to a collapse of a matter with some characteristic
mass of particles, its full mass should be restricted from the
bottom. For usual baryonic matter, this limit of mass is of the order
107M☉

The Dirac "square root" tetrads of the metric tensor are spin 1 fields that are intrinsically renormalizable for
quantum gravity models. Spin 2 gravitons are EPR entangled pairs of S-wave spin 1 tetrad quanta. As in
superconductors there may be higher P & D wave relative orbital angular momenta as well as S-wave spin
0 and spin 1 micro-quantum corrections that do not show up in the long-range "classical" (macro-quantum
coherent) limit. Both the c-number tetrads and the spin connections in our model are emergent from the
eight gluon vacuum condensates of QCD that form in the inflationary phase transition. Their residual
micro-quantum operator parts are the spin 1 quantum fields that are responsible for both the dark energy
and the dark matter. Spread out dark energy with negative pressure comes from w = -1 random zero point
virtual bosons of positive energy density that antigravitate because of the equivalence principle. Similarly,
clumped dark matter comes from w = -1 random zero point negative energy density fermion-antifermion
vacuum polarization loops of positive pressure that gravitate and is indistinguishable from w = 0 CDM for
the distant observer. Therefore, the CERN LHC will not detect any exotic real particles that can explain
ΩDM ≈ 0.23 if this theory is correct. New conjectured expressions for important physical observables
both at the micro and macro levels in rotating frames are presented. They need to be tested in the
laboratory, for example, alleged anomalous gravity from rotating superconductors.

I apply the principle of event-symmetry to simple string models and discuss how these
lead to the conviction that multiple quantisation is linked to dimension. It may be that string
theory has to be formulated in the absence of space-time which will then emerge as a derived
property of the dynamics. Another interpretation of the event-symmetric approach which embodies
this is that instantons are fundamental. Just as solitons may be dual to fundamental particles
instantons may be dual to space-time events. Event-symmetry is then dual to instanton statistics.
In that case a unification between particle statistics and gauge symmetry follows on naturally
from the principle of event-symmetry. I build algebras which represent symmetries of superstring
theories extending event-symmetry but which are also isomorphic to an algebra of creation and
annihilation operators for strings of fermionic partons.

To accommodate topology change, the symmetry of space-time must be extended from the
diffeomorphism group of a manifold, to the symmetric group acting on the discrete set of space-time
events. This is the principle of event-symmetric space-time. I investigate a number of physical
toy models with this symmetry to gain some insight into the likely nature of event-symmetric
space-time. In the more advanced models the symmetric group is embedded into larger structures
such as matrix groups which provide scope to unify space-time symmetry with the internal gauge
symmetries of particle physics. I also suggest that the symmetric group of space-time could be
related to the symmetric group acting to exchange identical particles, implying a unification
of space-time and matter. I end with a definition of a new type of loop symmetry which is
important in event-symmetric superstring theory.

Comments: submission to the 2008 FXQi essay contest on "The Nature Of Time". Published in Presapcetime Journal V2, p162-171
In relativity time is bound to space by the symmetries of spacetime. In the general theory the symmetry is
covariance under diffeomorphisms but in string theory this extends to the full permutation group acting on spacetime
events. This huge symmetry has profound implications for the nature of time, causality and the way we see our place
in the universe.
