How would the numbers change if we discovered life, let alone "intelligent" or more "advanced" life?
Folks, this super long winded reply is just for RevRico…by all means, just pull a TL;DR.
They wouldn’t.
The numbers are what is commonly referred to as the “probabilistic resource” which is the number of opportunities “think dice rolls” that have occurred in the history of the universe. This number is a function of the number of atoms in the universe times the age of the universe times the number of random pairings of atoms per unit of time.
Atoms…The estimate for the number of atoms in the “visible” universe has been fairly stable over time and pretty broadly agreed upon and we clearly don’t need to concern ourselves with the non-visible universe since if even light can’t interact with us, there’s no chance that physical matter such as genetic code could. Although it’s known that the vast majority of the matter in the universe is in the form of hydrogen & helium gas (have fun trying to assemble genetic code with that) not to mention that much of it is sequestered within stars and black holes, we ignore these limitations and give full credit for all matter in the universe contributing to the probabilistic resource.
Time…this is an easy number to plug in as there’s broad agreement that the universe is about 13.77 billion years old and the number hasn’t moved more than a few decimal places in a long time.
Pairings per unit of time…this is by far the most difficult number to estimate so to ensure we’re giving the Neo-Darwinist the most generous chance possible, we apply what are known as Planck minimums for time (5.39 X 10 to the minus 44) and distance (1.62 X 10 to the minus 35). Essentially this represents the number of interactions that would occur per unit of time if every atom in the universe were as close to each other as physically possible and they were all pairing up at the speed of light.
As Duke pointed out, this is a mind bogglingly huge number but given how many dice rolls are required to produce just one single fairly simple protein anywhere in the universe throughout its entire history, the odds work out to be a trillion, trillion, trillion to one.
To understand why, just place the probabilistic resource in the numerator and get to work calculating the denominator which is the number of random pairings required to code for that one lone protein. The code contained in DNA is based on four amino acids (A-T-C-G) and there are ~150 base pairs required to code for a relatively simple protein (the average is up around 350). Alright, use the formula “L” to the power of “K” where “L” represents levels in this case being 4 (A-T-C-G) and “K” represents factors in this case being 150 for the number of base pairs required to code for a simple protein and you get 10 to the power of 196.
I know these numbers can be overwhelming so just think about a simple combination lock with 4 tumblers each having ten digits (0 to 9). “L” to the “K” gives us 10 to the power of 4 or 10,000 combinations (0 to 9,999).
Of course, there could be many other ways to store genetic code than A-T-C-G but we’ve already accounted for that by having our probabilistic resource include every atom in the universe so the calculation is valid regardless of what type of matter is used.
The real question is what is the smallest amount of information required to get something that can self-replicate, mutate, and has no barrier to evolving into the life we see today. Answering that questions is way above my pay grade but the consensus among top researchers including Nobel prize winners that have been experimenting for decades is that it’s wildly greater than what is required for our little protein that requires 150 base pairs of code which again, stands only a trillion, trillion, trillion to one chance.
RossD very correctly pointed out that religion has always filled in where science is lacking or as one famous Intelligent Design refuter said “ID is just theology in a cheap suit”.
Well, I’m not an ID proponent, I’m agnostic on the subject so that’s a strawman argument in my case as it is the case for a big percent of the others that are looking at this.
Yesterday, I posted in the Minor Rant thread…”if you don’t know the price, don’t tell people the price.”
It’s the same with Neo-Darwinism…I won’t be at all surprised if we one day make a discovery that greatly reduces the information required to get something that again can…self-replicate, mutate, and has no barrier to evolving into the life we see today.
Until such time though, Neo-Darwinist have no business spiking the ball in victory and they sure shouldn’t be scoffing at those that realize that their current theory can’t possibly be right.
As that little old lady in the commercial said “it doesn’t work that way, none of it works that way”
