Abstract: | A simplified formula for gravitational‐radiation power is examined. It is shown to give completely erroneous answers in three situations, making it useless even for rough estimates. It is emphasised that short timescales, as well as fast speeds, make classical approximations to relativistic calculations untenable (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim) |
