  2. 2 SpaceFacts™

  3. Trust me, I’m a (former) professional.

  4. Everything you need to know about space

  5. 1. Space is really big

  6. 2. Space is cold

  7. 3. Stars are hot

  8. 3.14 π is everything

  9. Large asteroids contain more aluminum, gold and platinum then what

    has ever been mined on earth
  10. At least 5 bodies have been found beyond Pluto that

    are bigger than Pluto (Why its not a planet anymore)
  11. There is more water on Jupiter’s moon Europa then all

    the water on Earth
  12. Statistically there is a habitable earth-like planet within 20 light

    years of Earth, now its only a question of when we find it
  13. It’s estimated that there are 100 to 500 billion galaxies

    in the Universe, each of which has hundreds of billions of stars.
  14. Hold on to your minds…

  15. The big bang occurred at a specific point in time.

  16. What was going on before that?

  17. The universe is continuously expanding

  18. What is it expanding into?

  19. Given the universe has a finite amount of energy, and

    that the universe continues to expand, eventually the universe will no longer be able to support actions which require energy
  20. Cards Against Humanity fans:
 that’s the inevitable heat-death of the

    universe
  21. Alternate theory:
 The universe expands then eventually contracts into another

    singularity, eventually restarting with another big bang (The Big Bounce)
  22. Fermi’s Paradox: tl;dr •Given the age of the universe there

    should be galaxy-spanning civilizations by now. •Earth should already have been colonized, or at least visited. But no convincing evidence of this exists.
  23. Some reasons: •We’re the first intelligent species capable, give us

    a bit of time! •All intelligent life eventually “shorts out” see: Great Filter. •They do exist, but we see no evidence (e.g. bacteria vs blue whales). •Internet addiction (seriously).
  24. Thanks for listening!
