Astronauts are usually pretty busy while they're off planet so there hasn't been a lot of time to, um, look into this stuff, but it's unclear whether humans can procreate in weightless conditions. Apparently, you can't just march into space like you own it and do whatever you want. Read More >>

Why do you kiss? Because it makes you feel good down there? Because it'll hopefully lead to something that'll make you feel great down there? Probably. But what about the science behind why we kiss? Vsauce, our favourite scientific talking mouth who needs no water during his soliloquies, explains that it's something to do with being babies. Read More >>

Humans come in all shapes and sizes, but when it comes to height there seems to be an unofficial limit on how tall someone can be. On average, the tallest of humans measure in at around seven-feet six-inches, with a few Guinness-worthy cases breaking the eight foot barrier. But why is that? Read More >>

So you've got yourself a car that needs lifting, and have secured an industrial crane for the job, but did you also remember to get a giant harness for the lift? Probably not. Don't worry, though, as long as you can scrounge a few rolls of sellotape, you're good to go. Read More >>

When you think of the vast emptiness of space, one of the first things to come to mind is probably violent decompression. But is the vacuum of space powerful enough that it could suck out an entire ocean through some sort of gigantic space straw? Read More >>

This is actually a pretty great thought experiment. At first it might seem kind of pointless to talk about what would happen if the sun vanished, but it doesn't actually result in the immediate destruction of everything. Which is weird. Vsauce walks through a pretty nuanced description of how earth's natural systems would slowly fail, but over weeks and even years, not seconds. The cold would get us in the end, but extremophiles that live in deep sea volcanoes and thermal vents could survive for billions of years. If you're not heliocentric and human-centric things don't look so bleak. [Vsauce] Read More >>

Every time the football World Cup rolls around (as well as any number of other times), those of us who aren't into football ask ourselves this question: we do people care about sports at all? Vsauce has taken the question a bit further, and dug into why we—as a species—play games at all. Nerds, we've got more in common with those jocks than we might have thought. [Vsauce] Read More >>

The geniuses behind Vsauce scientifically answered a few questions, as only they can, about whether it makes sense to eat yourself if you're ever suffering from starvation, how does hair know when to stop growing, what eye floaters are, how much would Wikipedia weigh and more. Read More >>

It's nearly impossible to use Comic Sans on the internet and not get tarred and feathered. It's an internet sin of the highest level. A crime against human decency and people's eyeballs. A parody of a joke of a fool. Universally hated. So... is it possible to defend the font? Is Comic Sans wrongfully reviled? Maybe! Read More >>

We've been taking pictures for almost 200 years now, and we sure aren't slowing down. But how many pictures have we taken all together, since photography existed? Well the short answer is around 3.5 trillion, but there's a lot more nuance than just a flat number. Vsauce looked into the matter in more detail, and some of the facts might surprise you. How many of the pictures are actually good? That's anyone's guess. [YouTube] Read More >>

We're sending rovers to Mars to try and figure out our place in the universe, but what about our place on Earth? Sure, Earth is a big place, but you might be surprised exactly how insignificant we all are in contrast with its mammoth mass. Read More >>
