Of course, it was more in response to assigning the probability of life to 1/infinity when NASA's Kepler team estimates 50 billion exoplanets, 500 million of which in earth like habitability zone in orbit around a sun.

Life is not improbable.

thats right.
In part they come up with those numbers based on how atoms are thought to be formed. In stars. Given the fact that most stars can make carbon, oxygen, and some of the other row 1 and 2 stuff. I think even red dawrf can some of the stuff. These red darwf's make up most of the stars. Not main sequence ones. To be clear, stars that are out there, not ones we can see. This universe was going to have life. i remember in the 80's saying "there are planets". People said "you can't say that." Based just on what we know about the P.T. I said, we will find planets. Life is the same. It may be special. Maybe even scarce (gamma ray sterilizers) but it is out there. RE: Life is not improbable.

Wrote: I just want to know how we've arrived at a statistical measurement of the probability of life occurring from a sample size of one. If its as simple as combining water and carbon they should have already been able to replicate it in the lab. It appears that abiogenesis requires more than just the coming together of ingredients. It requires a recipe. The existence of water, wheat, salt, and yeast, make the existence of bread more likely.....but it certainly doesn't guarantee it. RE: Life is not improbable.

Skepticism is not a position; it is an approach to claims.
Science is not a subject, but a method. (April 8, 2014 at 7:50 pm)tor Wrote: All life needs is 1 self replicating molecule and planet that make life possible. I think you are being too flippant. There is a vast gap between a self-replicating molecule and an organism of many molecules, most of which are not self-replicating in the strict sense of the word, that can nontheless systematically harness resources from its environment to create something like a duplicate of itself. It is true the vast gap is nonetheless likely to be bridged in the time available to the geologically active life of a earth like planet. But that's no excuse to be flip about "all it takes".
Heywood why do you still fail?
The probability of life evolving on a planet is X. X is higher than 0 because it is possible for abiogenesis to occur. If X is higher than zero then multiple attempts increase the chance of it happening. More planets = more chances = higher chance. (April 9, 2014 at 5:41 pm)tor Wrote: Heywood why do you still fail? The probability that life (as we know it) will evolve is 1. (April 9, 2014 at 8:38 pm)Heywood Wrote:(April 9, 2014 at 5:41 pm)tor Wrote: Heywood why do you still fail? Really? Is there such a thing as a priori probability being 1? Quote:The chances of that life being on our intellectual level or above, sadly nowhere near as high. Really? RE: Life is not improbable.

I'm using a definition for evolution here which is rather loose or broad......Basically I am thinking that evolution is just descent with change. But you are correct, it isn't 1 because over any time specified time scale I suppose there is a probability that life as we know it can occur were there is descent but no change. Thanks for prompting the thought. |
