I'm a Chemist, and a Bioinformaticst, not a Physicist.... I've no thoughts.

I ask, WHY would you wish to change it?

There is no reason to change it.


But the idea of trying to is interesting.

We all have odd interests I am sure.

Lets assume the human race evolves on and on for millions of years, and our technology evolves too. We'd need to evolve a lot more than a Level III Kardashev civilization

The problem with the Drake Equation and subsequent is this...

"4. fl, the fraction of those planets that actually develop life."

en.wikipedia.org...


To be specific Earth has experienced many mass extinctions.


So the extent to which such events made possible humans, could substantively alter how we define a Goldilocks zone.

That has nothing to do with this. It is quite simply, we'd need to evolve technologically beyond the dreams of our most optimistic.

Mass extinctions yes -- but not a 100% extinction of all life.

As far as we can tell, life only began once on Earth., not many different "starts" to life after many different extinction events. That is to say, all life on Earth seems to be related to that earliest of all life.

The little mammals that eventually became humans were already existing at the time of the K-T extinction event that killed the dinosaurs.

An applicable frame of referent would that that without that event Dinosaurs would still predominant Earth.

Yeah, but you were commenting on the " fl " factor of the Drake Equation, which as you pointed out is defined as:

"The fraction of planets that could support life that actually develop life at some point"

The Dinosaurs most certainly still qualify as "life". In fact, Earth satisfied the fl part of the Drake Equation 3.5 Billion years before the dinosaurs even existed.


I Think what you meant to question was the " fi " factor, which is defined as:

"The fraction of planets with life that actually go on to develop intelligent life (civilizations).

Agreed.

So the local group is moving at about 600 km/s or 1. 34 million miles per hour in the general direction of the Constellation Hydra. The Milky Way and Andromeda Galaxy are approaching each other at about 300,000 miles per hour or 130 km/s.

The local group is moving 600km/s relative to the cosmic background radiation. There are many 'speeds' that you could assign but the most elusive is to be able to reference it to the central point of expansion.
