I think we're a bit too late for radio silence. Even if our comms are indistinguishable from noise at that distance, I bet our previously detonated nukes would have sent distinctive pulses across the near cosmos.
I wonder, does SETI look for signs of alien nuclear wars?
- DougWebb 9y agoSomeone else can figure out the math, but I'm pretty sure the energy from all of the nukes that have been detonated, especially if you only count the open-air ones, is minuscule compared to what the sun gives off. That would mask any possible detection. I wouldn't be surprised if just the solar radiation that the earth reflects is enough to mask the nuclear blasts, unless you're viewing them from right inside the solar system.
- kobeya 9y agoThe spectral signature would be quite different.
- therein 9y agoWhat kind of unique signs would a nuclear explosion create? Doesn't nuclear fission occur naturally?
- kobeya 9y agoNot really? Only in very rare exceptions. At least if you're talking about chain reaction fission.

- labster 9y agoGamma ray bursts are from interplanetary war? That's a terrifying thought.
- CamperBob2 9y agoMy pet conjecture has always been that they're the interstellar equivalent of "Hold my beer and watch this..."
