Makes me wonder if alien life will actually not find our messages simply because we're using such "ancient" techniques. Perhaps they invented a TV like object and used a NTSC like signal, but like 100k years ago and no one in their race knows to look for our old signals. Maybe our comms look like hieroglyphics to them ?
- PaulHoule 4y agoPeriodicity is a clear signal that is useful for natural objects like pulsars. I think it would be very clear that analog videos are periodic at the line level and periodic at the frame level. If somebody gets the idea of plotting signals on a grid they will get a sequence of frames. Even creature that don’t see the way we do might develop some kind of raster basted signal processing. On top of that TV signals would have additional periodicity because the transmitters will be hidden behind the Earth once every 24 hours.
