remember the einstein's twins? one goes out to space, flies around a little bit, and when he comes back one of the twins appears to be 70 years older... the question is - which twin appears older - the one who was in space or the one who stayed on earth? what was actually meant - time difference caused by the "space-flying" twin moving with increadible velocities (relative to earth), or gravitational cunvolution of space caused by the mass of earth (one twin was "above" the other)
