[QUOTE="AbdulAlhazred, post: 6737742, member: 82106"] Except you CANNOT DO THAT, not even in principle. I think this reasoning is incorrect because its not 'human limitations' we're talking about here. It is limitations built into the rules by which the Universe fundamentally operates. Rules that operate at the same level as these various other rules like causality and thermodynamics. I'm not saying "your wrong", but I'm saying that there's a fundamental difference between say not being able to measure the distance to the Moon because we don't know how and not being able to measure the distance to a point outside our light cone because its fundamentally disallowed. Yes, I understand this. There are however regions of space, presumably, which are 'causally disconnected' from us. They are FOREVER outside our light cone. If I travelled instantly to the Sun then in 8 minutes light from that location would arrive and there would be different inertial frames of reference in which causality, conservation of angular momentum, etc would be violated.
