Gravitational Entropy or Negative Entropy of Quantum Biology and the Penrose Conjecture or Weyl curvature conjecture (WCC)

 If enough matter is present, gravity "eats up" space faster than light creates it, the universe collapses in a reversible process, and the entropy tally sums to zero. (Gravitational entropy is tallied as "negative" entropy, light entropy is scored as "positive", since the two act directly oppositely each other.

 (Gravitational entropy is tallied as "negative" entropy, light entropy is scored as "positive", since the two act directly oppositely each other. The implicit-explicit time "switch" is therefore also a positive-negative entropy "switch".)

  The light Universe does not contain an explicit time dimension, it is purely spatial, which makes sense in that being one-way, time is an asymmetric dimension which would destroy the metric symmetry of light-space.

 Obviously, time is implicit in the frequency of light, but at c time is prevented from becoming explicit. The seed is present, but its growth is suppressed; indeed, time would be required in its explicit aspect should light assume its particle form and produce matter. In fact, we need to discover the origins of the time dimension in light if we are to build a truly unified theory of energy and its dimensional conservation domains, a theory which traces the origin of all forces to light.

 Those statements are basically self-published with no citations of the study. I've never seen those claims before. Let's compare them to other studies on gravitational energy.

We examine whether, in the vicinity of the initial singularity, the ratio of the energy density of free gravity to that of matter density goes to zero, validating Penrose's conjecture on Weyl curvature. Whenever this is true, the gravitational entropy increases monotonically with time, leading to structure formation.

 According to him, the problem of spacetime singularities held the key to the
“origin of the arrow of time”.

 So they seem to think Penrose was wrong...

Penrose proposed the Weyl curvature conjecture (WCC) which hypothesizes that the
Weyl curvature tensor Cmnrs and the Weyl curvature scalar CmnrsCmnrs vanish at or near the big bang. This means that somehow the universe began as a homogeneous and isotropic
Friedmann–Lemaître–Robertson–Walker (FLRW) spacetime. Whether or not the initial big bang event was described by a singularity (the singularity could be erased by quantum gravity), this strong constraint can be made consistent with the second law.
