Reply to comment by jimmydevice in How long do you predict it will take before a probe reaches a habitable exoplanetand actually sends back footage of alien life? by sky_shrimp

Infinity being an infinite universe.

But in this case it should be whatever fraction of the 100 billion or so stars in the Milky Way have planets that are potentially habitable, instead of the infinity that is the whole universe. We are probably not sending probes to other galaxies for the better part of 5 billion years or so, until Andromeda comes to us.
