Your arms float in front of you while you sleep in space.
Astronaut Marsha Ivins spoke to Wired and describes exactly what life is like up in space. She described that in order to sleep on the shuttle, “you strap your sleeping bag to the wall or the ceiling or the floor, where you want, and you get in. It’s like camping.”
“The bag has armholes,” she continued, “so you stick your arms through, reaching outside the bag to zip it up. You tighten the Velcro straps around you to make you feel like you’re tucked in. Then you strap your head to the pillow — a block of foam — with another Velcro strap, to allow your neck to relax. If you don’t tuck your arms into the bag, they drift out in front of you. Sometimes you wake up in the morning to see an arm floating in front of your face and think, ‘Whoa! What is that?’ until you realize it’s yours.
If this makes you uncomfortable, float your hand way up in the air. Yeah, me too.
There's a giant black hole shooting through space at 3 million miles per hour.
Black holes are like mythically dangerous.
Apparently, this black hole is about 2 billion light-years away…for now. Who knows when it’ll reach us?!
There are almost certainly aliens but we haven't been visited yet, at least not in a way that we are capable of perceiving.
Scientists are pretty sure that there are billions upon billions of other Earth-like planets in the universe, and yet we get the feeling that we are very alone — it’s called the Fermi Paradox and it’s way more complicated than I can understand.
But the point is, there are probably other intelligent life-forms, and either they haven’t bothered to visit us, don’t know that we’re here, or have tried, and we as humans are just so limited in our capabilities for perception that we don’t even know how to communicate with them.
Which brings me to my last fact about space…
WE DON'T EVEN KNOW WHAT WE DON'T KNOW ABOUT SPACE.
Guys, space is larger and crazier than we can perceive or imagine. We may never grasp the vastness of it. And that’s why I think we should just give up. It’s dangerous. If aliens want to talk to us someday, cool. If not, cool. I don’t want to live in space. I don’t even want to visit it.
Let’s fix the Earth first.
