Why Relativity Would Mess Up Car Headlights

The crew over at Vsauce has set out to answer a very important and critical question: would car headlights work at the speed of light? Unsurprisingly, the answer is not simple, but in the process, you do learn a lot about general relativity and photons and other sciencey stuff. » 2/26/15 11:08pm 2/26/15 11:08pm

Why Earth isn't flat and why you wouldn't fall off of it even if it was

Some people seriously think that the Earth is flat. No one can save them. But the always thinking Vsauce explores the possibility and tries to figure out if the Earth actually could be flat in his latest video and details some rather interesting things about a flat Earth: that life would suck on it and that we… » 12/04/14 7:08pm 12/04/14 7:08pm

Mind-blowing video shows how humans are basically bad copies of amoebas

Vsauce, the master answerer of life's toughest questions and professional blower of minds, tackles something so philosophical in his latest video that you'll start to wonder what in the hell our purpose is on this Earth. And if it's any different than a purpose of a rock. It starts with the discussion of art and then… » 4/15/14 1:58am 4/15/14 1:58am

Thor's Hammer Is So Heavy It Would Kill Everything

There's a common misconception that Thor's hammer was forged from a dying star. It wasn't! It was forged inside of one, ya dummy. But just for fun, what would happen if Thor's hammer actually had been forged from a neutron star's demise? » 3/20/14 12:55pm 3/20/14 12:55pm

Who Owns The Moon?

The moon is not as far away as some things, but it's definitely farther away than your nearest McDonalds or the bottom of the ocean or, you know, anything on Earth at all. Basically it's not easily accessible. So it would be pretty presumptuous for a person or group to say that they owned a certain part of it. Or all… » 9/15/13 8:00pm 9/15/13 8:00pm

Yeah, What's The Deal With Clapping?

Sometimes I have an out of body moment where I see myself as an audience member and think about how dumb-looking the whole process is. You sit somewhere. You gape at something and don't monitor your facial expression because you assume no one is observing you, and then often, you clap. It's definitely a cultural… » 8/25/13 5:57pm 8/25/13 5:57pm

What It Would Be Like If You Were Trapped Inside a Mirror Sphere

There's not a single soul in the world who doesn't love it when they get to see the endless world that appears when you're in a room of mirrors. I remember trying to count as a kid how many versions of myself I could see. But what would happen if you were in a perfect mirror sphere? Vsauce, as only he can, explains… » 8/10/13 1:00am 8/10/13 1:00am

If You Don't Live For Billions Of Years You're Gonna Miss Out

The average human lifespan is a lot longer than it used to be. But we're barely into triple digits here and if we individually want to see anything awesome we're gonna have to stick around for a few degrees of magnitude longer. That immortality thing or whatever. Why haven't we done that again? » 7/28/13 6:55pm 7/28/13 6:55pm

What Would We Do If Aliens Just Showed Up Tomorrow?

It seems unlikely—impossible, even—that aliens would just happen to make contact today. Or tomorrow. Or the day after. But what if they did? How do you even deal with something like that? » 7/13/13 9:04am 7/13/13 9:04am

What Would Be Different About A Baby Born In Space?

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. » 5/12/13 3:00pm 5/12/13 3:00pm

Science Explains Why We Kiss

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 favorite scientific talking mouth who needs no water during his soliloquies, explains that it's something… » 5/01/13 8:00pm 5/01/13 8:00pm

How Tall Can a Human Get?

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? » 4/16/13 8:51am 4/16/13 8:51am

How Many Strips of Packing Tape Do You Need To Lift a Car?

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 cellophane packing tape, you're good to go. » 4/08/13 4:20pm 4/08/13 4:20pm

Is the Vacuum Of Space Strong Enough to Suck Up the Earth's Oceans?

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? » 4/06/13 7:30pm 4/06/13 7:30pm

What If The Sun Just Totally Disappeared?

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… » 3/31/13 12:00pm 3/31/13 12:00pm

Why Do Humans Play Games?

Every March (as well as any number of other months), those of us who aren't into sportsketball 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… » 3/23/13 9:00pm 3/23/13 9:00pm

How Much Would Wikipedia Weigh?

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. » 3/05/13 1:00am 3/05/13 1:00am

Is It Possible to Defend Comic Sans?

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! » 2/11/13 9:00pm 2/11/13 9:00pm

How Many Pictures Have Ever Been Taken?

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… » 11/10/12 10:00am 11/10/12 10:00am
