The Drake Equation: Is there really other Life in the Universe?

[DaveC426913]

If time is a factor, for a viable planet to develop atmosphere, then organisms, then intelligent life, then advanced civilization... then we add the effect of gravity on time.. then perhaps the worlds closest to the gravity well at the centre of our galaxy would be further along the evolutionary/advancement scale.

No. GR has a vanishingly small effect.

I think I recall a discussion here that our galaxy has a habitability zone where the conditions are more friendly to life. I had suggested that the older stars near the central hub would have older civilisations but there are also much higher levels of radiation around there.

Also, all those Population III stars are much poorer in metals.
