If every star in the night sky is a signal is it possible to send data to other galaxies by intermittently blocking out the suns light in that direction? (lemmy.dbzer0.com)

Sure you can put it farther away, but the sun is massive, it would still need to be pretty big I would guess, but I'm not an astronomer so I don't know the numbers.

As far as I know we don't know of any faster way to send signals. That doesn't make sending the signals impossible, just very impractical.

    How about this, we point it at blackholes hoping they act as a worm hole and then are transmitted to people a million years in the past and we instruct them to write the data down on stone tablets so when they advance due to also giving them advance technology they remember to send a note back.

    Sure we can do that, but then we can also just think hard about it and hope anyone hears it, not much of a difference

    Thats all just math's. We could create a theoretical model and send enough data where we maximize the probability. All be, the probability would still be starkly low but still an interesting thought experiment.
