Exploring the Effects of Space Time Expansion on Unbound Bodies

Click For Summary

Discussion Overview

The discussion centers around the effects of space-time expansion on unbound bodies, particularly exploring whether forces other than gravity, such as magnetic or electrostatic forces, can counteract this expansion. Participants are examining theoretical implications and the nature of forces in the context of cosmic expansion.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants assert that space-time is expanding and that gravitationally bound bodies remain unaffected, while unbound bodies are influenced by this expansion.
  • There is a question about whether gravity is the only force that can counteract the effects of space-time expansion, with suggestions that magnetic or electrostatic forces might also play a role.
  • One participant refers to the concept of the Cosmic Scale Factor for Gravitational Energies, implying a deeper inquiry into how gravitational energies relate to cosmic expansion.
  • Another participant expresses a desire for further commentary on a linked article that discusses relevant thought processes, indicating that the ideas presented may have broader implications for related discussions in theoretical physics.
  • A participant mentions difficulties in understanding certain technical aspects of the discussion, suggesting a need for clarification on the relationship between torque and gravitational forces in the context of space-time expansion.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus, as there are multiple competing views regarding the forces that can counteract space-time expansion and the implications of gravitational energies.

Contextual Notes

Some participants reference complex equations and concepts that may not be fully explained, indicating potential limitations in understanding the underlying assumptions and definitions related to the forces discussed.

It is my understanding, that space time is expanding, and that
gravitationally bound bodies will stay unaffected by this expansion
while unbound bodies will.
but is gravity the only force that can overcome this effect?
could magnetic or electro static forces hold bodies in station?
I do not propose this as an alternative theory, rather i want to
know if the mentioned forces grow with ST

What you are really asking is,what is the Cosmic Scale Factor for Gravitational Energies?

its a old posting (about 16 months ago) , that happens to have some far reaching insights contained.

Great link Olias

I hope some will comment on the thought process that was detailed.

It seems valid for our converstaion in strings/lqg thread in regards to smolin

L is not that clearly identified as torque as in my G = xy, but in g of equation (1) we have Lc^2 r/3 so that L is just throwing in r* factor essentially and the whole g composite looks like a "vacuum energy" torque. Regarding L as a force, on the other hand, then we have a torque (admittedly with a rather unusual force arm) and from the r" equation the g term eventually dominates in r". r" is like a force without a mass in the Newtonian "ma" force picture, but I suppose that L contributes its own "mass"

I have had some difficulty digesting this, I have read the article several times
now and i think i understand, but because i have only just climbed out of my
tree a little more insight would be appreciated.
