My questions from different topic are ignored, so let me start a new thread from stratch that is dedicated purely to UA.
The concept of UA is the following:
Everything within the visible universe is accelerating at 9.8m/s^2 along with the FE. Within our frame of reference, we will experience acceleration to be a constant 9.8m/s^2. To someone outside the accelerating frame of reference, they would see the acceleration decrease as the accelerating FOR approached the speed of light. The accelerating FE/universe would require an infinite amount of time to reach the speed of light.
Well, that obviously creates few problems.
1. Acceleration rate is not constant.
2. There is no "outside", so how can we talk about any FOR not being accelerated?
3. What does UA accelerate?
What is the reason that when I jump, I land back on the floor?
Suggested answer:
When you are no longer in contact with the FE (directly or otherwise), you are no longer accelerating and have become inertial. The FE is still accelerating, and will catch up to your body. When you recontact the FE (again, directly or otherwise) you are again being accelerated.
created even more questions, all are mine:
But... why? Isn't UA supposed to accelerate EVERYTHING?
Or UA chooses what it wants to accelerate? So only the Earth, Moon, starts etc, but not objets on them. It does not make any sense.
Does the UA accelerate me sitting on my chair or it does not?
If yes, then why do I stop being accelerated by the UA when I jump?
If no, then why does it accelerate the Earth but not me?
Any clear and explicit explaination?
Question 1. was given a hand-waved answer, so I do not bother quoting.
Question 2. remains unanswered.
Question 3. - provided answers are unclear and produced even more questions.
This is in debate, because I want to discuss this, not to just receive an answer that may (not) make sense.
