It could mean that these compounds formed in the protoplanetary disk and then were carried to planets on asteroids. Or it could mean that collisions between life-bearing planets and asteroids seeded other planets with the compounds necessary for life-- and potentially that life began elsewhere than on Earth. This is known as Panspermia, which is what I have been thinking about for many years: https://en.wikipedia.org/wiki/Panspermia This discovery answers a lot of questions, like why life began so early after the Earth cooled-- because Earth was seeded with organic material by asteroids that bombarded Earth during that period. Taken in conjunction with my latest comments about A.I. and quantum effects on cognition, I think there is one logical conclusion: God is inside the universe with us and God created DNA, which permeates the universe through percolation. Discovering life on another planet in the solar system would, however, be the worst news in the history of the world because it means the Great Filter is ahead of us, not behind us. The Great Filter is the only remaining barrier between humanity and us filling the universe. If life began somewhere other than Earth, that has a lot of implications and my head is spinning right now with what it all means, hence the early hour of this post. This is freaking crazy. #News Thu, 30 Jan 2025 02:47:40 -0800 Andy from private IP Reply #15687463 This discovery can be interpreted in several ways, but even the most conservative interpretation is that the precursors of life are found everywhere in the universe. If you assume that amino acids and nucleotides form naturally in protoplanetary disks, that means every star system could have some form of life descended from its own naturally forming compounds. That still doesn't answer the question of how DNA actually formed or where our lives really originated. I did a little more research and found that "pseudo-panspermia" is the correct term for the discovery: https://en.wikipedia.org/wiki/Pseudo-panspermia Thu, 30 Jan 2025 03:25:27 -0800 Wily from private IP Reply #14839829 The Great Filter could be intelligent life or intelligent life with a civilization capable of sending out electromagnetic radiation. I mean even assuming intelligent is fairly common, think about all the what-ifs that could've prevented humanity from reaching 20th century level technology. If modern humans evolved about 200,000 years ago, the first 190,000 years they basically did Nothing, with population densities too low to advance beyond hunter-gathering with Stone Age tools. Even look at 700 years ago, the world was basically in an advanced Iron Age state everywhere - there was no guarantee there would be a Renaissance, Scientific Revolution, or Industrial Revolution. Aboriginal Australians or Native Americans, if they remained undiscovered, wouldn't be anywhere further along today than 500 years ago. What guarantee is there that an intelligence alien form wouldn't have the same technological stagnation either before or after agricultural revolution? Or some sort of stable equilibrium with their ecosystem, like the aliens in Avatar, for example.
