The Alien Cleaned Genome Question | Summary and Q&A

TL;DR

Life on other planets may have different genetic codes and could potentially be a hidden shadow biosphere.

Key Insights

• 🤳 RNA and DNA are crucial for storing information in self-replicating molecules, making them essential for life.
• 🧑‍🔬 Minimal genomes help determine the bare minimum genetic requirements for life, and scientists have created artificial cells with minimal genomes.
• ❓ A cleaned, streamlined genome could represent perfection and may be a result of panspermia or intentional seeding by an advanced civilization.
• 👽 Detecting radio signals from alien civilizations may provide information on their genetic codes and potentially allow us to recreate alien life forms.
• 👽 There are possibilities of receiving friendly, harmful, or superior alien genomes, but the technology to recreate alien organisms does not currently exist.

Transcript

It could be said that life begins with RNA, self replicating molecules that can store information. That ability is necessary for life, and it’s hard to imagine how life could exist without that kind of storage medium to start out. After all, how is nature to build an organism without a set of instructions? It doesn’t seem very plausible that it cou... Read More

Questions & Answers

Q: What are some possible forms of life suggested independent of DNA?

Neutron star life and plasma-based life are exotic and speculative possibilities, but there is currently no evidence supporting their existence.

Q: Why would finding genomes be important in the search for alien life?

Genomes can reveal if microbial life on other planets is truly independent or related to Earth's life through panspermia.

Q: Are messy genetics common in natural alien species?

Yes, messy genetics are likely because natural evolution leads to large amounts of junk DNA and genetic diseases. Messy genetics are a result of billions of years of evolution.

Q: What is a shadow biosphere?

A shadow biosphere refers to a second genesis of life on Earth that is different from known life forms and can only be detected through non-conventional methods.

Summary & Key Takeaways

• RNA and DNA are essential for life as they store information needed to build organisms in nature.

• Alternative forms of life, such as neutron star life or plasma-based life, are hypothetical and speculative.

• The search for alien life should focus on finding genomes to determine if it is truly independent from Earth or a panspermic cousin.
