the amount of time it takes to reach the Earth from these…
““the amount of time it takes to reach the Earth from these stars will be greater if the aliens can’t travel at near light speed. If they can only travel at half light speed then it would take them 44 years to get from Tau Ceti, for example. If they can only travel at one-tenth light speed then only Alpha Centauri A and B would realistically be within range – and the aliens would have to come from a planet orbiting one of those stars too.””
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
Travel time from stars depends on alien speed; slower speeds limit reachable stars, affecting potential contact.
In simple terms: Alien travel speed determines which stars they can reach.
Key Takeaway
Consider speed limits in space exploration.
