You cut it, and the plane wouldnt technically "de-orbit" until that wave hit the plane

The really scary thing is that we can't even say that, since the term "now nonexistent" is meaningless due to simultaneity being relative.

Nonexistent. You keep using that word. I do not think it means what you think it means.

Just because it dies doesn't mean it's mass vanishes. It'll just change into a black hole or white dwarf if it doesn't become a nebula.

If you have a taught rope from England to NY and pulled, you would feel it instantly on the other end. Molecular interactions can be FTL.

ahh, the old light-year-stick question. Nah compression only happens at the speed of sound.

9 years ago | Likes 6 Dislikes 0

No, you would not. Molecular interactions are mediated by the electromagnetic forces, which are carried by photons, which travel at c.

9 years ago | Likes 11 Dislikes 0

Yes, the actual propogation is at the speed of sound in the material - but no matter the material, that fundamentally cannot exceed c as 1/

9 years ago | Likes 1 Dislikes 0

It actually doesn't. The speed of the pull is still information, and has to travel the length of the rope at the speed of light.

if gravitational effects travelled instantaneously, you could move a mass at one point, and an observer lightyears away could detect 1/2

this movement instantaneously by observing the change in its gravitational influence, hence instantaneous FTL communication
