Or perhaps we are a only advanced civilization in the known universe and other civilizations are using some lo-tech method of communication like creating sounds or fire signals. Add we are looking for only high-tech modes of communications.
- Filligree 8y agoThanks, I am now imagining interstellar smoke signals. I feel like that's pretty unlikely, though. :X
- function_seven 8y agoI'm assuming parent meant they're communicating across their own world using those forms, and we should be looking for timed puffs of smoke :)
- russfink 8y agoFantastic - but at what interval? Our lives may be measured in years, while another life form may measure itself in eons. How rapid must their oscillators be to download their own equivalent of Netflix? 1E-08 Hz? (Can we detect such slow oscillations? Is there a minimum timescale for consciousness?)
- function_seven 8y agoUsing an SDSSD¹ they wouldn't need to tune to any specific oscillation. Just collect the data and start Fourier-ing it to find the signal. 1: Software-Defined Smoke Signal Detector
