Time doesn't really exist. 👀

It's certainly relative.

There is no universal now, which is why Satoshi invented a distributed clock.

It's strange because it's absurd. Motion is caused by applying pressure and in "space" it is apparently a vacuum. Therefore you can't have motion.

Wrong, rather. It would appear red-shifted, length-compressed and time-dilated, but none of that means its apparent movement stops for the observer. It will continue to appear moving at an accelerating speed (without ever reaching the speed of light).

I'm just an amateur student, but I'm pretty confident that's how this whole General Relativity thing works.
