New preprint drop: The PEG Reactor is now live on OSF!
What if symbolic overload isn’t just noise—but a structural force?
A thought experiment meets proto-biotic recursion: vibrational logic, nested feedback, and the architecture of self.

Origin of Life
In Origin of Life: What Everyone Needs to Know®, David W. Deamer has written a comprehensive guide to the origin of life that is organized in three sections. The first section addresses questions such as: Where do the atoms of life come from? How old is Earth? What was the Earth like before life began? Where does water come from? After each question is answered, there is a follow-up: How do we know?
What if the Goldilocks Zone was everywhere?
It once was.
Kurzgesagt explores a fascinating hypothesis: For a period from about 10 to 17 million years after the Big Bang, the average temperature of the entire Universe was between 0C and 100C, that is, where liquid water could form, known as "the Goldilocks Zone": not too hot, not too cold, just right.

Additionally:
The first giant stars would have already zipped through their hydrogen fuel forming the essential elements of life and blasting that through the interstellar medium: carbon, oxygen, nitrogen, phosphorus, and sulfur (along with, of course, hydrogen, itself primordial).
By at least one measure, evolution of DNA suggests a biological origin at roughly this time.
Life seems to have emerged on Earth roughly the instant conditions were favourable for it (e.g., the Floor Was Not Literally Lava, and liquid oceans formed).
It's been a long time since I've run across a staggeringly original and at least arguably plausible concept. This one ... makes my head spin. This isn't the first time I've run across the concept of panspermia --- the notion that life emerged effectively everywhere. It is the first time I've seen a plausible argument made supporting the notion.
Questions are how the idea might be supported or disproved. Multiple biological samples from extrasolar objects, particularly of both different directional origin and showing a common biological ancestor, might suggest this. Life on other bodies within the solar system could also strengthen the argument as might be signs of strongly distinct and advanced early life forms on Earth, suggesting distinct origins as the primordial Earth was "seeded" by organic forms of independent origin. Contra arguments might be indications that the early Universe was exposed to too much ionising radiation for stable organic and genetic material to have formed.

Hello, fediverse! Here's my #Introduction. I'm a freelance #Science #Journalist and #Editor. When I write, it's usually about #Chemistry and #Biochemistry - think #Plastic waste , #DrugDiscovery , #OriginOfLife ; I also cover #DC #Food and #Restaurants. I'm currently secretary of the DC Science Writers Association and volunteer for the National Association of Science Writers, so you'll see event-related toots here as well.
