Can Time Be Saved From Physics?
Philosophers, physicists and neuroscientists discuss how our sense of time’s flow might arise through our interactions with external stimuli—despite suggestions from Einstein's relativity that our perception of the passage of time is an illusion.

Thermo-Demonics
A devilish new framework of thermodynamics that focuses on how we observe information could help illuminate our understanding of probability and rewrite quantum theory.

Gravity's Residue
An unusual approach to unifying the laws of physics could solve Hawking's black-hole information paradox—and its predicted gravitational "memory effect" could be picked up by LIGO.

Could Mind Forge the Universe?
Objective reality, and the laws of physics themselves, emerge from our observations, according to a new framework that turns what we think of as fundamental on its head.

Essay Abstract

There is a chasm between points of view and no agreement on what is fundamental between thinkers, whatever is the field they belong to. So, what I intend to show it is that time might actually a gateway to deep questions is the fundamentals of nature, or what is behind it.

Author Bio

I work for INPI (My Brazil's trademark and patent office). I graduated in Physics. I am curious about many things.

Hi Daniel,

Very good essay. I know you hate the boring ordinary, so you opted for something that could be fundamental yet exiting about reality. The subject has always been on my list but never got the time to delve. I have the book by Matt the Lorentzian wormholes.

Keep walking, do I have a choice!

Your paper makes some interesting connections with closed timelike curves. These are existent in the interiors of Kerr, Reissnor-Nordstrom and Kerr-Newman metrics and black holes. The Kerr black hole has r = 0 in the x-y plane as a ring that has closed timelike curves around it. This black hole interior has spacetime so twisted up and screwy that these time loops structures are real. They are also apparent in anti-de Sitter spacetimes, but one often considered a conformal patch where these are excluded. The Taub-NUT spacetime flips the meaning of space and time, so the analogue of the black hole and the horizon at r = 2GM/c^2 occurs with a time in the past as t = 2μ/c^2. Before that time there is a region with closed timelike curves. In all these cases we have conditions on the nature of the vacuum which correspond to the violation of Hawking-Penrose energy conditions. In the case of black holes or the Taub-NUT solution these regions are sealed behind event horizons.

The holonomy you discuss is a form of monodromy of a curve around a singularity. A closed timelike curve is often associated with a Cauchy horizon with a weak singularity, such as what happens with a wormhole, or with CTCs around black hole singularities in the RN or KN metrics. These have very interesting structures, and I think the holonomy or monodromy of a black hole singularity is dual to the poles in geodesics in hyperbolic spaces and the theorems of Mirzikhani. The near horizon condition of a black hole is a form of AdS spacetime which has the effect of bringing this structure into the exterior region.

As a result this does have some bearing on relevant physics, even though I suspect that faster than light travel or time travel is not possible in the general exterior world we experience.

Cheers LC

Time is not a dimension. Time is an evolution parameter. Time is modeled as a dimension only in some theories that avoid the true nature of time, including its characteristic arrow. But those limited theories cannot describe irreversible phenomena.

Dear Daniel,

Here we are again all together.

I highly appreciate your beautifully written essay.

I hope that my modest achievements can be information for reflection for you.

Dear Daniel

If you are looking for another essay to read and rate in the final days of the contest, will you consider mine please? I read all essays from those who comment on my page, and if I cant rate an essay highly, then I don’t rate them at all. Infact I haven’t issued a rating lower that ten. So you have nothing to lose by having me read your essay, and everything to...
