A civilization using this method might not use optical systems to focus the beam like we do, but might individually fire precisely aimed photons.

- thatcherc 8y agoYou'll have a similar problem due to the Uncertainty Principle. Even a single photons will experience the same kind of diffraction as a beam of photons, limiting the degree to which you can aim it.
- rickycook 8y agoassuming that we got that right and didn’t just misunderstand what we are seeing (or assuming that there’s no “side channel” to know how to correct for it) we also can’t get to a black hole, so for this civilisation it’s safe to assume they have a significantly better understanding of physics than us. we don’t know what we don’t know
- gus_massa 8y agoThe reason that makes it imposible to avoid the dispersion even of a single photon is not technological, it's a theoretical reason. You can't solve it with more advanced technology, you must change the laws of Physics. It is sure that the current laws of Physics are incomplete, and some may even be wrong, but this effect is so fundamental and the proof is so simple that I doubt it will change.
