Hello to you. I hope this finds you well in your today. My mind was traveling yesterday and the things that came up were pretty interesting! The travels had to do with communication, light, the fact light travels faster than sound, the movie K-pax and talking about traveling faster than light – tachyon speed, communication traveling faster than light – called superluminal communication. I was thinking about the current ways that are being used to try and intercept messages from other worlds and it all seems to be sound based. There is so much “noise” emitted from earth and in space and it’s difficult to split out what is normal and out of the ordinary. I feel certain God’s work extends well beyond us and our current capabilities to communicate. What if more advanced worlds are trying to communicate with us using light waves or something even faster? In between the light of stars, planets and galaxies I wonder if there are messages? People far smarter than me are probably already exploring such possibilities!
Light waves travel much faster than sound waves. Light waves do not need a medium in which to travel but sound waves do. Explain that unlike sound, light waves travel fastest through a vacuum and air, and slower through other materials such as glass or water.
A tachyon (/ˈtækiɒn/) or tachyonic particle is a hypothetical particle that always travels faster than light. Physicists believe that faster-than-light particles cannot exist because they are not consistent with the known laws of physics. If such particles did exist they could be used to send signals faster than light.
Superluminal communication is a hypothetical process in which information is sent at faster-than-light speeds. The current scientific consensus is that faster-than-light communication is not possible, and to date it has not been achieved in any experiment. Wikipedia
