Does abiogenesis require a multiverse?


1. Emergence of life in an inflationary universe
https://www.nature.com/articles/s41598-020-58060-0

"Abiotic emergence of ordered information stored in the form of RNA is 
an important unresolved problem concerning the origin of life. A polymer 
longer than 40–100 nucleotides is necessary to expect a self-replicating 
activity, but the formation of such a long polymer having a correct 
nucleotide sequence by random reactions seems statistically unlikely. 
However, our universe, created by a single inflation event, likely 
includes more than 10^100 Sun-like stars. If life can emerge at least 
once in such a large volume, it is not in contradiction with our 
observations of life on Earth, even if the expected number of 
abiogenesis events is negligibly small within the observable universe 
that contains only 10^22 stars."


2. The cosmological model of eternal inflation and the transition from 
chance to biological evolution in the history of life
https://link.springer.com/article/10.1186/1745-6150-2-15

"Origin of life is a chicken and egg problem: for biological evolution 
that is governed, primarily, by natural selection, to take off, 
efficient systems for replication and translation are required, but even 
barebones cores of these systems appear to be products of extensive 
selection."

"The plausibility of different models for the origin of life on earth 
directly depends on the adopted cosmological scenario. In an infinite 
universe (multiverse), emergence of highly complex systems by chance is 
inevitable. Therefore, under this cosmology, an entity as complex as a 
coupled translation-replication system should be considered a viable 
breakthrough stage for the onset of biological evolution."

"The crucial question, then, is how was the minimal complexity attained 
that is required to achieve the threshold replication fidelity. In even 
the simplest modern systems, such as RNA viruses with the replication 
fidelity of only ~10-3, replication is catalyzed by a complex protein 
replicase; even disregarding accessory subunits present in most 
replicases, the main catalytic subunit is a protein that consists of at 
least 300 amino acids [20]. The replicase, of course, is produced by 
translation of the respective mRNA which is mediated by a tremendously 
complex molecular machinery. Hence the first paradox of OORT: to attain 
the minimal complexity required for a biological system to start on the 
path of biological evolution, a system of a far greater complexity, 
i.e., a highly evolved one, appears to be required. How such a system 
could evolve, is a puzzle that defeats conventional evolutionary thinking."

"The second paradox of OORT pertains to the origin of the translation 
system from within the RNA world via a Darwinian evolutionary process: 
until the translation system produces functional proteins, there is no 
obvious selective advantage to the evolution of any parts of this 
elaborate (even in its most primitive form) molecular machine. 
Conceptually, this paradox is closely related to the general problem of 
the evolution of complex systems that was first recognized by Darwin in 
his famous discussion of the evolution of the eye [16]."


3. Drake Equation for the Multiverse: From the String Landscape to 
Complex Life
https://arxiv.org/abs/1002.1651?utm_source=chatgpt.com

"It is argued that selection criteria usually referred to as "anthropic 
conditions" for the existence of intelligent (typical) observers widely 
adopted in cosmology amount only to preconditions for primitive life. 
The existence of life does not imply in the existence of intelligent 
life. On the contrary, the transition from single-celled to complex, 
multi-cellular organisms is far from trivial, requiring stringent 
additional conditions on planetary platforms. An attempt is made to 
disentangle the necessary steps leading from a selection of universes 
out of a hypothetical multiverse to the existence of life and of complex 
life."


4. Multiverse Predictions for Habitability: Origin of Life Scenarios
https://arxiv.org/abs/2303.02678?utm_source=chatgpt.com

"If the origin of life is rare and sensitive to the local conditions at 
the site of its emergence, then, using the principle of mediocrity 
within a multiverse framework, we may expect to find ourselves in a 
universe that is better than usual at creating these necessary 
conditions. We use this reasoning to investigate several origin of life 
scenarios to determine whether they are compatible with the multiverse, 
including the prebiotic soup scenario, hydrothermal vents, delivery of 
prebiotic material from impacts, and panspermia. We find that most of 
these scenarios induce a preference toward weaker-gravity universes, and 
that panspermia and scenarios involving solar radiation or large impacts 
as a disequilibrium source are disfavored. Additionally, we show that 
several hypothesized habitability criteria which are disfavored when the 
origin of life is not taken into account become compatible with the 
multiverse, and that the emergence of life and emergence of intelligence 
cannot both be sensitive to disequilibrium production conditions."
