But as I corrected the question, can a substance (space) that is just an electromagnetic medium move if it's sealed or does the external electromagnetic medium (space) ignore the seal and the two become one. My last question is when do the two become one if you have initially filled the tube with air and it slowly leaks out until there is a vacuum inside the tube. So it goes from the air in the tube having a speed to the space in the tube not having a speed, it just fixes to the background space and the tube effectively disappears or at least its sealed ends do.

But if your car is moving relatively to them and your car comes to a stop, you will age slower than them in the time between when you come to a stop and they see that you have stopped.

Also note that Jorrie doesn't see the difference between something being falsified vs not agreeing with the status quo. Meaning.. if one doesn't agree with Relativity then they are automatically falsified in his view.

Yes, the same. I'm just an amateur so I often get in trouble for not knowing terms.

Perhaps it's best to let that thread remain a shining example of how a legitimate challenge is met with obfuscations, ad hominem slurs, and finally.. censorship via lockout.
