Hello all, today i'mma make a thread about, random science facts! What do you do? Post some random science facts! Thanks to the people at for inspiring me to make this thread! I'll start: Some fun facts about light and shadows that may answer some questions. A electron can move faster than light in water. Photonic booms, sonic booms but with light instead of sound, are possible, and exist. Light has force. It can move things. You technically weigh more under light than in darkness, that the city of Chicago weighs pounds more on a sunny day, and light can move a spacecraft travelling from Earth to Mars 1,000 km off course. The brightest point of a shadow of a circular object is the middle. Sources and more information:
