An Event Road Map

Explore the intricate timeline of life’s emergence, starting from stellar events like supernovae that create the elements essential for life. Delve into the delivery mechanisms of water through asteroids and comets, and the significant role of Jupiter in our solar system's water network. Discover how energy sources, such as lightning and ocean heat vents, contributed to the formation of essential organic compounds. Understand the slow evolution from simple RNA/DNA to complex life, and the challenges faced, leading to the question: Are we alone in the universe?

  1. An Event Road Map

  2. A Container of Life

  3. Star Formation and Element Creation

  4. Supernova are your Mother

  5. Expect Solar System Formation

  6. Expectations are Confirmed

  7. Now we have a Rock – how does life arise? • Water on Earth: • Outgassing – NO • Delivered Later • Delivery Mechanism • Asteroids – Maybe • Comets – Probable • NEED JUPITER

  8. The Water Network of the Solar System

  9. Life Begins in the Oceans Result is the production of simple organic compounds. Energy source could be lightning in the atmosphere Or Heat Vents in the Ocean

  10. Now Need to Make Macro Molecules Trial and Error Process to make RNA/DNA Took about 1 Billion years

  11. Then simple to complex: DNA needs protection from Oxygen or it dies. Oxygen production comes from aerobic organisms but they need chlorophyll to capture enough solar energy to metabolize H2O and give off Oxygen as a waste product. Chlorophyll is a Big Molecule – that’s why it works

  12. Chemistry Now gets in the Way It takes 2 Billion years for this process to stop

  13. Takes Time to Make Ozone Layer

  14. Land Stimulates Diversification

  15. Now you need to Survive!

  16. So Life is Tough! Long Term Survival is Difficult. Period.

  17. Are we Alone? =1% of 1 Billion 10 Million 1/10 1 10 1 1 1/10 =1 million

  18. Implications of N= 1 million • 1 Civilization per 100,000 stars • Nearest random one is 1000 light years away! • Life (all life) is RARE! • If intelligent life is UNIQUE to the Earth then either: • F_i = 1 in a billion • L = 1000 (for everyone) !! • This seems unlikely and therefore, with proper planetary management, one day we will be in the club and know the answer.
