This is one of those neat ideas which probably makes engineers laugh. This thing, with a mass of a gram, needs to survive the pretty unpleasant radiation environment that travelling that fast involves. Then it has to transmit information to us using whatever fraction-of-a-gram power source it has ... which we need to detect, from 25ly away.

If we can solve engineering challenges like that, then, well.
