if you think about it, the fact that we can reliably communicate with the New Horizons space probe is kind of absurd
you need extremely high gain antennas to have any hope of an SNR greater than one, and even then you need fancy techniques to be able to extract data with an SNR lower than one because too bad, your SNR at that range still isn't greater than one despite the high gain. the signals we get from New Horizons are about -150dB, after including the antenna gains in the calculation
@Felthry -150dB is spooky to even think about.
