A light-year is the distance light can travel in 1 year. Light travels at 300,000 kilometers (186,000 miles) per second. Commercial television broadcasting began in 1939. Television signals travel at the speed of light. How far away would a space probe have to be before it could no longer detect those signals?

- Clouds of hydrogen in space often emit light with a wavelength of 656.3 nanometers. This type of light is emitted from galaxies that are moving away from Earth at great speed. When astronomers detect photons of this type from those galaxies, those photons of light will, have a longer wavelength and more energy than the emitted light or have a longer wavelength and less energy than the emitted lightarrow_forwardEinstein said that gravity exists because: * A. massive objects warp space. B. of the existence of black holes. C. massive objects attract one another. D. light moves randomly throughout the universe.
