Gravitational Waves of Early Universe

Click For Summary

Discussion Overview

The discussion centers on the relationship between the moment of 'first-light' in the early universe and gravitational waves originating from the Big Bang. Participants explore the implications of inflationary dynamics, luminosity pressure from emerging galaxies, and the detection of gravitational wave signatures in the cosmic microwave background (CMB).

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant questions whether the 'first-light' moment corresponds to the first gravitational wave signature from the Big Bang, proposing that two processes—dark energy inflation and luminosity pressure—contributed to the motion of galaxies.
  • Another participant notes that gravitational waves are predicted to emerge from inflation prior to galaxy formation and mentions ongoing searches for these signatures in the CMB.
  • A later reply highlights a potential problem related to the luminosity function at large distances, suggesting that it may not be observable locally and indicating a need for further clarification through research.
  • Several papers are referenced that may provide insights into the topics discussed, although their specific contributions are not detailed.

Areas of Agreement / Disagreement

Participants express differing views on the relationship between gravitational waves and the first-light phenomenon, with some asserting a connection while others emphasize the distinct nature of gravitational waves arising from inflation. The discussion remains unresolved regarding the implications of luminosity pressure and its observational challenges.

Contextual Notes

Participants acknowledge the complexity of the luminosity function and its implications for understanding gravitational waves, indicating that assumptions about observational capabilities and the nature of early universe phenomena may be limiting factors in the discussion.

Was the moment of 'first-light' or 'Lights-on' which occurred in the early Universe when Matter started to Shine 'light from the first galaxies', equivilent to the first Gravitational Wave signature from the Big-Bang?

If one was do insinuate that the first primordial outward 'inflation' wave was Dark, or transparent, then the period of Outward Inflation was halted by an opposing signal, a signal that Extracted Energy from within the Dark Energy which caused Matter to emit Light, or become visible.

The Galaxies that emerged from this period of the Early Universe must have been driven apart by Two CO-INCIDING PROCESSES?

One being the remnant of Dark Energy Inflation, the other being the Luminosity pressure that must have been present as Galaxies Appeared:

The 'lights-on' scenario, must have contributed to an 'inward-force-pressure', the sudden vast outpouring of light from matter that was located at a fraction of the present Universe size.

Every individual Galaxy would have a Luminosity 'force' , and if Inflationary Dynamics are near Equilibrium, the force of Light emmited by early Galaxies, would have contributed vastly to the motion 'away' from every other Galaxy.

Gravitational Signals must be embbeded within the 'high' Luminosity Function, not within the Low Energy COBE background radiation?

Two recent papers have a baring on interesting solutions to the post above first paper:

http://arxiv.org/abs/gr-qc/0505045

and the second companion paper:http://arxiv.org/abs/gr-qc/0505046

The authors are :R. Chan, M.F.A. da Silva and Jaime Fernando Villas da Rocha.

Then there is this amazing paper: http://arxiv.org/abs/astro-ph/0505210

and another first class paper:http://arxiv.org/abs/astro-ph/0505217

this will be relevant:http://arxiv.org/abs/astro-ph/0410467

as these:http://arxiv.org/abs/astro-ph/0412134
http://arxiv.org/abs/astro-ph/0412135
finally for a good perspective of SNe

Gravitational waves are predicted to come out of inflation, long before the formation of galaxies. In fact, we're looking for gravitational wave signatures in the CMB.

Agreed!..but there lays a problem..and I am going through a number of papers, which I am hoping will iron-out what I believe is an important problem, and it relates(I think?) to the Luminosity Function at Large Distances, which cannot be Observed or detected at a Local Distance?

I hope to make some headway and clarify further in a number of days time.
