Acceleration/Deceleration

And what is your basis for saying those things?

 

I just cannot accept on basis on logic that reality has a multiple essence.

[Sisyphus]

Reality is not obligated to be easy to grasp, or to conform to arbitrary philosophical restrictions. What you are refusing to accept is something that theory predicts and experiment confirms. And it does not contradict logic.

(...) And it does not contradict logic.

 

No kidding.

[J.C.MacSwell]

Restricting observation to objects at rest one's own frame of reference is very limiting.

 

..and not advisable in traffic.

You are a smart and educated person. As such, you have no need to relax under the umbrella of knowledge of other people smarter than you. When people say that reality is not easy to grasp, it is too often an excuse for unintelligible explanations.

Theory predicts observations, and yes, Relativity is right because experimental observations correspond to Theory. The point is not on whether Relativity is right or wrong. The point is on the way one interprets what observation is.

 

When you say that observation is exactly the same thing as reality, what you obtain is insanity (IMHO). From multiple observations, you obtain multiple realities. You are at the same time yourself & a pancake, and because some observator far away decides so, you can not step into your car and accelerate for the simple reason that in his FOR it is physically impossible to observe.

 

But when you say, as I do, that there is a gap between observation & reality, nothing weird happen. Still you are a pancake for the other observator, and Relativity applies on all his observations. But you know better, because you are your own FOR, and you know that no law of nature can stop you to sit in your car and go for a trip.

for the simple reason that in his FOR it is physically impossible to observe.

As I understand relativity, you can not single out one specific effect and consider how that would impact reality, every effect of relativity needs to be transferred when switching frames. When relativity is applied properly a physical event is either possible or impossible equally in all frames. If it's possible in one frame then it's possible in all frames and similar if it's impossible in one frame then it's impossible in all frames.

 

The laws of nature applies to all frames so Sisyphus can slide into his "pancake" car and accelerate for a trip in any distant observer's view. Different observers might disagree on his size, mass, speed, acceleration, how long time the trip took and when the trip did happen, but they will all agree on that he actually made the trip and which roads he choosed during the travel.

No, if it is physically impossible in one frame, it is physically impossible in all frames. All inertial frames have the same laws of physics. Any apparent paradox caused by length contraction will be resolved because of time dilation and the relativity of simultaneity.

There are no roads in the antipods.

[Spyman]

LOL, If you drive the Virgil with Unobtainium Hull there is no need for roads.
