Discussion Overview

The discussion revolves around the question of whether light speed can ever be reached in the universe, exploring theoretical implications, energy requirements, and various cosmological models. Participants engage in conceptual reasoning and debate regarding the nature of light speed and the energy dynamics involved.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • Some participants propose that light speed will never be reached due to the infinite energy required, suggesting that no finite region of the universe contains infinite energy.
  • Others challenge the assumption that energy dissipated during the big bang is a limiting factor, questioning the adequacy of energy during that event.
  • One participant argues that regardless of the energy available, the speed of light remains constant and cannot be surpassed, regardless of repeated attempts to accelerate.
  • There is mention of Moffat's theory, with a request for peer-reviewed references to support claims made about it.
  • Another participant points out that many particles in the universe already travel at light speed, prompting a clarification on what is meant by "light speed."

Areas of Agreement / Disagreement

Participants express differing views on the reasons light speed cannot be reached, with no consensus on the validity of the arguments presented. The discussion remains unresolved with multiple competing perspectives.

Contextual Notes

Some claims rely on specific interpretations of cosmological models, and there are unresolved questions regarding the definitions of energy and speed in the context of light speed.

Is it fair to say light speed will never be reached because the energy required has been dissipated or used during the big bang...?

How do you know there was enough energy to do that during the big bang in the first place?

No, it would be fair to say that light speed will never be reached because the energy required would be infinite! And no finite region of the universe has ever contained infinite energy.
 
So is it fair to say...Infinite to a point.

No, it is not "fair" to say that unless you have a specific reason to. Can you cite any of the cosmological model that would justify such a view?

No matter how much energy you have used to accelerate yourself, even all the energy in the universe, you will still measure the speed of light in all directions to be the same as it was before you started. Then if you could do it over and over again, as many times as you wish, you'd still be right where you started from in terms of getting any closer to the speed of light.

So, no, it's not fair to say that the reason you cannot reach the speed of light is for lack of energy.
 
How about Moffat's theory

Please cite the exact peer-review reference of your source.

Yes it is fair to say but you need to prove!

Light speed of what? There are plenty of particles in the universe that are already traveling at light speed.
