Flash Talkin’ w/ Derek Springer Park City Grand Meetup -
Trust me, I’m a (former) professional.
Everything you need to know about space
1. Space is really big
2. Space is cold
3. Stars are hot
3.14 π is everything
Large asteroids contain more aluminum, gold and platinum then what
has ever been mined on earth
At least 5 bodies have been found beyond Pluto that
are bigger than Pluto (Why its not a planet anymore)
There is more water on Jupiter’s moon Europa then all
the water on Earth
Statistically there is a habitable earth-like planet within 20 light
years of Earth, now its only a question of when we find it
It’s estimated that there are 100 to 500 billion galaxies
in the Universe, each of which has hundreds of billions of stars.
Hold on to your minds…
The big bang occurred at a specific point in time.
What was going on before that?
The universe is continuously expanding
What is it expanding into?
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
Cards Against Humanity fans: that’s the inevitable heat-death of the
Alternate theory: The universe expands then eventually contracts into another
singularity, eventually restarting with another big bang (The Big Bounce)
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.
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).
Thanks for listening!
