Velocity Measurements in Some Classes of Alternative Gravity Theories
arXiv:1210.1569 · doi:10.1007/s10509-013-1524-0
Abstract
The general misconception regarding velocity measurements of a test particle as it approaches black hole is addressed by introducing generalized observer set. For a general static spherically symmetric metric applicable to both Einstein and alternative gravities as well as for some well known solutions in alternative gravity theories, we find that velocity of the test particle do not approach that of light at event horizon by considering ingoing observers and test particles.
