Which of the following statements about lookback time is INCORRECT? All telescopes are subject to the 'lookback' phenomenon. The 'lookback' phenomenon is a consequence of the finite speed of light. Because of the lookback phenomenon, cellphone signals sent from Earth-orbiting satellites are delayed relative to those from nearby cell towers. The 'lookback' phenomenon is a limitation in the construction methods of modern telescopes that we will eventually overcome with better designs. An alien in a distant solar system viewing Earth through a telescope today could see the Egyptians building the Pyramids.
