The grandfather post is probably misremembering something like "it will become a sphere expanding at greater than the speed of light" around the time it is Solar-System-sized.
(Pro Physics Tip: This is not allowed.)
- largbae 7y agoDepending on how you measure it could be allowed... the diameter of the sphere could grow faster than the speed of light without any component exceeding c because you can grow at near light speeds in two directions.
- ClumsyPilot 7y agoI think the point was that's the answer given by extrapolation, and its obvoiusly physically impossible. The contradiction with laws of physics is the point. For starters, anything that large wo ui pd collapse into a black hole.
