I have a curiosity. I do not have a degree in science (going to university later this year) so this should be very simple to follow. I'm looking for a refutation (preferably with words and not unnecessary equations), confirmation, maybe a link to this sort of stuff. I'm aware that as an object approaches C, stationary observers see it contract in the direction of motion. From the perspective of the object, space itself contracts in the direction of motion. The typical A-level physics question I would do would be a muon traveling at a percentage of the speed of light, and from that working out how long a 2km atmosphere would appear to the muon. Take something like this and have it be two-dimensional, circulating across a sphere. Or in a real example, something in orbit approaching the speed of light (and gravity to keep it there). It seems to me that since from space constantly being contracted in the direction of this thing's velocity (even if the velocity's direction is changing), the circumference of the sphere will likewise seem smaller. In other words, a satellite orbiting a sphere causes the radius of the sphere to shrink (relative to the satellite).
