What Are We REALLY Using Space Lasers For?

The video explores the evolution of space communication, starting with early ideas like Robert Goddard's magnesium flash powder. It explains the electromagnetic spectrum, focusing on radio waves used for communication. The limitations of radio waves, such as slow data transmission and signal weakening, are discussed. The video then introduces optical lasers as a promising alternative, highlighting their ability to transmit more data over greater distances. It concludes with the potential for lasers to replace radio waves in future space communication.
