That’s one of the questions I answered in this week’s Ask Joe video:
My answer? I’d go back to the single day, approximately 2 billion years ago when one cell gulped up another one, and instead of eating it, created the mitochondrion. Our little cellular energy factory, formerly a free-living organism, is the key to the evolution of quite literally all complex life on Earth, plant or animal. As Ed Yong writes in his history of the mighty mito, it happened only once. I’d just want to watch it happen under a microscope, so I could say “Yep, that’s why I’m here.”
Oh man. But what if I sneezed or something? I could ruin the whole universe. On second thought …
Cool, huh? What’s yours?
I’d watch a star ignite. The point at which it no longer a bunch of gas and becomes self sustaining.
Less than 10 minutes into Cosmos and already Neil Tyson has already dropped bombs.
Talking about the various beliefs about comets that the ancient tribes of Africa believed. He named them individually and their theories.
He also noted that we know the names of mass murderers but not scientists.
How arrogant we inhabitants of Earth to believe that we are the only ones who can/do exist in the Universe.
Just about to post something like this.
Sometimes when I think about the universe and all of the celestial events that take place, I feel really sad that I’ll never see them.
Something like the seeing a star ignite for the first time, witnessing a supernova, seeing a nebula in all it’s beauty, following the trail of a comet, or seeing a comet flying into a star.
I bet an astrophysicists/ astronomer will tell me that none of this is even possible as a star takes a few millennia to do any of that and it’s not overnight. But still, I want to see it.
