For me it is the fact that our blood contains iron. I earlier used to believe the word stood for some ‘organic element’ since I couldn’t accept we had metal flowing through our supposed carbon-based bodies, till I realized that is where the taste and smell of blood comes from.

    Time relativity always boggles my brain, I accept the fact but I find crazy that if I strap my twin and his atomic clock to a rocket and send them out to the stratosphere at the speed of light, when they return he’ll be younger than me and his clock will be running behind mine. Crazy

    There is about 8.1 billion people in the world. Assuming romantic cliches to be true and that we all have exactly one soulmate out there, we would have a very hard time sifting them out. If you were to use exactly one second at meeting a person it would take you 257 years to meet everyone alive on earth at this moment, which due to human life span being significantly shorter and the influx of new people makes the task essentially impossible without a spoonful of luck. Moral of the story: If you believe you have found your soul mate, be extra kind to them today.

    There’s a giant ball of extremely hot plasma in the sky and we aren’t supposed to look at it. What is it hiding? Surely if someone managed to look at it long enough, they would see the truth!

      I’ve seen some of its secrets during the eclipse. It’s an angry, writhing tentacled thing. Be thankful it’s so far away.

    Speaking as someone who grew up in the 1980s…

    Micro-SD cards almost don’t make sense to me. I’m not saying I don’t believe in them, because of course I have a few of them. Obviously they exist and they work. But. They’re the size of a fingernail and can hold billions of characters of data. I uwve a camera that ive put a 128 GB microSD card in. A quick tap on the calculator tells me that’s over 91,000 3.5" floppy disks. Assuming they’re 3mm thick, that’s a stack of disks 273 meters tall. But this card is so tiny that I have to be careful not to lose it.

        I remember my parents talking about some thing or other in star trek that would be impossible because you’d need “terabytes of storage, and that’s probably not possible”. And now you can go buy 1 tb of storage and lose it in your couch cushions.

    Your bones are made of calcium, which is also a metal. You’ve got a metal frame inside your body.

      I thought my significant other was one of these to a certain extent. It does weird things to me as a DJ. Turns out that she just likes the limited music that she likes and cannot stand most everything else.
