30th Space Symposium, Main Stage. This may seem a bit familiar to some of you, especially those who have been dedicated fans of Neil deGrasse Tyson, who gave the keynote speech for the 28th Space Symposium.
“We’re driving down the road running our GPS, it is working, we find our destination…nobody is thinking about satellites. They’re just thinking, did they get to their destination in time. It’s like shaving. No one will come up to you and say hey, you shaved real good today! The act of doing it perfectly is the measure of it going unnoticed.”
— NDT, in reference to the “hidden role that space plays in our culture”
Watch the whole keynote speech. It’s inspiring and may change you (or others) to start thinking about society, culture, and the future through the cosmic perspective. When I was in this room, that entire speech played back in my mind.
Every star is a sun as big, as bright, as our own. Just imagine, how far away from us you’d have to move the sun to make it appear as small and faint as a star. The light from the stars travels very fast. Faster than anything. But not infinitely fast. It takes time for their light to reach us. For the nearest ones, it takes years. For others, centuries. Some stars are so far away it takes eons for their light to get to Earth.
By the time the light from some stars gets here they are already dead. For those stars, we see only their ghosts. We see their light, but their bodies perished long, long ago.

"There are two great mysteries that overshadow all other mysteries in science. One is the origin of the universe. That’s my day job. However, there is also the other great mystery of inner space. And that is what sits on your shoulders, which believe it or not, is the most complex object in the known universe. But the brain only uses 20 watts of power. It would require a nuclear power plant to energise a computer the size of a city block to mimic your brain, and your brain does it with just 20 watts. So if someone calls you a dim bulb, that’s a compliment."
