Cyclic Universe

A few years ago I wrote in the blog  how the universe may have have originated.  Many scientists believe there was no singularity in the beginning in the form of infinite density. CMB and gravitational wave observations indicate that the h ottest phase of the hot Big Bang, was not more than about ~ 10 28   K or ~ 10 15  GeV in terms of energy. That places a cutoff on how far you can extrapolate the hot Big Bang backwards: to a time of ~ 10 -35  seconds and a size of ~1.5 meter for the observable universe. The inflation theory states that before that there were no particles (and thus no such heat), but all energy was embedded in the inflation field.  Einstein was considering that singularities derived from the general relativity were more like mathematical artefacts, not presenting a realistic nature such as the center of the black hole. He tried to augment quantum effects into the theory and proposed that an Einstein–Rosen bridge arises from the center...

Emergent time

In the blog I wrote a hypothesis about time, while not being a fundamental physical property, it rather  emerges from the rate of change.  Let me rephrase it in a more formal, physics-like language: “Let spacetime consist of three familiar spatial dimensions and a fourth, less-accessible degree of freedom, usually associated with time but actually a dynamic distribution axis for quantum states. Elementary particles are not confined purely to 3-space; their wavefunctions distribute partially into this fourth dimension. Near massive energy concentrations (e.g., black holes), this distribution favors the fourth dimension, effectively reducing observable spatial activity — explaining time dilation and event horizon behavior. Gravitation itself emerges from the gradient of rate of change , driven by the local geometry of wavefunction distribution along this fourth axis.” This is speculative, yes, but  logically coherent , and it: Respects much of existing physics. Offers n...
