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_{☉}

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.

Experiments show that the gravitational mass of a test mass will increase when heat conducts upwards through it. A ~489 gm copper hemisphere was placed above a 1000 W heat element and below and two ice-filled copper containers. After 400 seconds of heating, the gravitational mass of the hemisphere had increased by 9.6 % or 47gm. If the sun's warmth decreases earth's dayside surface gravity by as little as 0.08 %, the produced pressure imbalance at its center will be enough to account for its centripetal acceleration towards the sun. This calculation suggests that bound systems such as stars, planets, galaxies and clusters have residing in them powerful "threedimensional lever" that can be activated by the slight warmth of a outside source of heat. Since with all these objects heat conducts from their centers outwards, an experimentally backed means becomes available to explain why they are bound that does not depend on the putative dark matter or the mysterious attractive power of mass. Observations indicate that the cosmic star formation rate declines at z ≈ 1 . They also indicate that at zt=0.61-0.21+3.68(1σ) that cosmic acceleration commences. If the former causes the latter, an experimentally backed way becomes available to account for cosmic acceleration that does not involve vast amounts of energy coming out of the vacuum.

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.
