This is because governmental agencies such as the National Aeronautics and Space Administration (NASA), the Naval Research Laboratory (NRL), the US. The speed of light (in a vacuum) equals 3 × 1010 cm/sec (centimetres per second); at such a speed, it is possible to circle the Earth seven times in a single second. However, you will require knowledge that is similar to what is expected for GCSE. In 1926, the famous American astronomer Edwin Hubble refined a system that classified galaxies into categories of spiral, elliptical, lenticular or irregular shape.
