- michaelmrose 2y agoAre we basing that on the tens of thousands of years between stars required for chemical propulsion instead of the tens of years feasible with other options?
- lazide 2y agoIt’s all based on energy and economy. The amount of energy required (even for a relatively slow chemical rocket!) is so astronomical, it’s apparently not worthwhile to do at scale. Or there are no actual aliens, except us. For whatever reason.
- dboreham 2y agoOr it is possible but we don't know what they look like.
- digging 2y ago> it’s that it’s impossible to create self replicating probes that can travel interstellar distance What makes you say that? I wouldn't actually think that's as difficult as many other problems in space exploration. An uncrewed probe is free from a lot of really challenging constraints.
- lazide 2y agoBecause we haven’t seen any - near as we can tell - ever. If they were possible, we should be having to constantly look up to avoid having one land on us.
- nilsherzig 2y agoWhy would the cutoff be at building self replicating probes and not before that?
- lazide 2y agoBecause self replicating problems should have some sort of exponential growth curve, and with the age of the universe should have fairly predictable time before full coverage. Other things wouldn’t.
