Laws of physics should be the same for an observer moving at a constant velocity or not moving at all (an observer cannot tell the difference between him moving and the world moving around him). That is the cornerstone of Special Relativity. Besides that, Special Relativity claims that lengths / distances shorten in the direction of motion: only in that direction, but not in an orthogonal/perpendicular direction. For an observer moving at a very high speed, all planets would look flattened:…Read more by Alexandre Kassiantchouk Ph.D.
