In summary: I'm not sure what you're getting at with this.If you're trying to say something like "if the two objects start out with the same rest mass, then when their rest masses have been converted to kinetic energy, the change in momentum of the object going forward will be the same as the change in momentum of the object going backward", then that's true. If you're trying to say something else, then I don't understand what you're saying.In summary, the conversation discusses a scenario where two objects of equal mass are accelerated in opposite directions with the same amount of force. The question is raised about whether the velocity of the launch site in the direction of either mass will cause a quicker acceleration in that direction. The experts clarify

If something is at rest
This is a meaningless description.
jerromyjon said:
So relative to this "something supposedly at rest" the fastest something can move away in any direction is .99999999c (or c if massless).
Or even closer to c (if not massless) if we put in more energy.

For every observer, physics looks exactly the same, no matter how they move relative to each other.

Ok then, Thank you all, I will just have to come to terms with this until I understand the math that explains it. I'm just so close to understanding SR and I'm nit-picking the parts that don't make logical sense to me. Believe it or not I'm actually very good with math I just haven't quite tackled calculus yet.

On that note, I think we can declare this thread done.
