Is The Universe Finite?

Is The Universe Finite?

There’s a lot of debate as to whether the universe goes on and on forever, or if you kept going, you’d eventually reach its edge. PBS Space Time digs into this astrophysics quandary. Whether the universe is geographically-flat and infinite, or it curves in on itself, it’s still more enormous than most of us can fathom.

If Spiders Were as Big as Humans

Are you an arachnophobe? Then skip this video. But if you can handle your spiders, then tune in to What If’s creepy crawly clip that envisions a terrifying world in which our eight-legged friends are as big as us. Get ready for a big bowl of nope.

Indian or Native American?

Indian or Native American?

In the first episode of his series “Reservations”, CGP Grey explains how the Europeans who took over America slapped a label on its indigenous people that would later be thought of as offensive, yet is still commonly used within tribes. Plus, the term selected to replace it has stirred controversy for other reasons.

What If You Never Felt Pain?

What If You Never Felt Pain?

Whether it’s a bee sting or a kick in the groin, pain sucks. But we need these unpleasant sensations so we know when something is wrong or when to avoid danger. Life Noggin explores the nature of pain, and some conditions which prevent people from feeling it.

What If We Didn’t Need Sleep

What If We Didn’t Need Sleep

We’ve pulled our share of all-nighters over the years, but have drawn the line somewhere around 36 hours without sleep. But the What If channel explores what life might be like if sleep weren’t a necessity for our brains and bodies. It turns out having all that extra time would have sweeping implications, both good and bad.

How Escalators Work

How Escalators Work

As long as we’re not carrying a heavy suitcase, we generally take the stairs when given a choice. But for those times when you feel like giving your legs a break, the escalator is quite the invention. Jared Owen provides an animated explanation of the inner workings of this engineering marvel that dates back to the mid-19th century.

How to Daft Punk

“Generally, Daft Punk likes to have A-Major good time.” Do you want to make music just like the robots? Then watch Imaginary Ambition’s lighthearted video tutorial, and if you work harder, better, faster, stronger, and you’re doing it right, you might just get lucky!

If You Never Pooped Again

If You Never Pooped Again

Despite people’s discomfort with the subject, pooping is something we all do. For shits and giggles, The Infographics Show decided to answer the hypothetical question of what kinds of horrors would happen if you never dropped the kids off at the pool again.

How a Gumball Machine Works

How a Gumball Machine Works

It’s a requisite stop for every kid with change in their pocket. But have you ever wondered how dropping a coin into a gumball machine makes it dispense a chewy treat? Animator and explainer of things Jared Owen gives us a detailed breakdown of its mechanism.

What’s a Neutron Star?

What’s a Neutron Star?

If you find space science fascinating, check out this clip from Kurzgesagt, in which they explain how neutron stars work. These phenomena may only be a few kilometers in diameter, but have an insanely dense atomic nucleus and powerful gravity, thanks to their origins as massive stars which have collapsed and gone supernova.

What Is The Scariest Thing?

What Is The Scariest Thing?

There are lots of things to be frightened of in the world, but is there a universally worst terror for all people, regardless of age, race, sex, culture or other attributes? Michael Stevens of Vsauce digs into the notion of fear, and how these unpleasant feelings are triggered in our brains. He also hates purple squares now.

Which Planet is Closest?

Which Planet is Closest?

We all learned the positions of the planets from some chart on the wall in grade school. But as CGP Grey reminds us, planets rotate in elliptical orbits at varying speeds around the sun, meaning that the answer isn’t quite as simple as you thought – depending on the question you’re actually asking.

What Happened to the Rotodyne?

What Happened to the Rotodyne?

Back in the 1950s, a new method of transportation was in development. The Fairey Rotodyne looked like the offspring of a helicopter and an airplane, and could take off and land vertically. But fast as it appeared, the Rotodyne vanished. Mustard takes a look at this unique aircraft, and why it never got off the ground.

If We Nuked a City

If We Nuked a City

It’s a terrifying thought, but in the interest of keeping us educated about the dangers of nuclear weapons, Kurzgesagt is here to teach us just how awful it would be if humans ever were ever to detonate a nuclear weapon in a city. Even worse, we actually did this to people back in WWII.

Talos: The First Robot

Talos: The First Robot

You might think that robots are a 19th or 20th century invention, but the idea of a humanoid machine dates back way further. TED-Ed looks back to an ancient Greek myth that involved a giant automaton warrior built to defend an island kingdom. It was also the first story about a robot struggling with its humanity.

The Secret US City

The Secret US City

During WWII, Oak Ridge, Tennessee served as a facility for nuclear weapons development, housing nearly 75,000 people, all while managing to keep the entire existence of the town top secret. Half as Interesting explores the fascinating history of this small southern town.

The Machine that Made Everything

All the Sounds in the Universe

All the Sounds in the Universe

Ever wonder what the quietest and loudest sounds in the universe might be? With the help of their imaginary robot Noisy, and Microsoft’s anechoic chamber, Bright Side digs into this question, and some of the science behind the way sounds travel and how our hearing works.

History of the Motherboard

History of the Motherboard

Computers and other gadgets cram a ton of componentry onto ever more compact circuit boards. But not that long ago, electronic circuits were anything but efficiently packed onto a small green motherboard. Techquickie looks at how we got from there to here.

How a Drinking Bird Works

How a Drinking Bird Works

If you’ve ever played with one of those drinking bird toys, you know it can be quite fascinating to watch as it dunks its beak in and out of a glass of water. Engineerguy Bill Hammack pops off the bird’s festive blue hat to explain the thermodynamics which make the nearly endless fun happen.

Why Can’t Planes Fly Backwards?

Why Can’t Planes Fly Backwards?

While jet engines do have the ability to reverse their thrust to slow down, or even taxi backwards, it’s not possible for an airplane to do the same in the sky. Bright Side provides a layperson’s explanation of the physics and safety issues that prevent this from happening.

7 Million Years of Human Evolution

7 Million Years of Human Evolution

Want to know about our genetic ancestors? American Museum of Natural History’s fascinating video takes us back to the moment where humans branched off from chimpanzees, and illustrates our progress via maps of significant archaeological discoveries.

Engineering with Origami

Engineering with Origami

While you might think that origami was exclusively an art form, engineers are taking inspiration from the paper-folding craft to create innovative designs that can shape-shift to fit objects to into smaller spaces, and enable compact mechanisms, while decreasing the number of parts used. Veritasium explains.

How Scary Sounds Work

How Scary Sounds Work

In a just barely Halloween-themed episode, musical expert 12tone walks us through the complexities of distortion, and what it is about such sounds that make them more creepy and off-putting than others – sort of like the way he draws from right to left across the page.

The First Video Game

The First Video Game

Ahoy presents an incredibly in-depth analysis of the origins of video games, swiftly debunking any confusion that Pong was the first video game ever, and looking back at early titles like Computer Space, SpaceWar!, Tennis for Two, and their programmers. Turns out hunting down the very first video game isn’t that simple.

If You Jumped Into Stomach Acid

If You Jumped Into Stomach Acid

The What If channel likes to imagine some pretty gory hypotheticals, but this one takes the cake so far, as they envision what might happen to our bodies if we were to jump into a swimming pool filled with stomach acid. TL;DW: just get out of there and hose off quick.

NASA’s Guide to Black Hole Safety

NASA’s Guide to Black Hole Safety

After seeing the Disney flick The Black Hole, we already were pretty cautious about visiting such an astrophysics phenomenon. But this clip from NASA Goddard provides some much more scientific reasons you’d never want to get close to one.

Why Animals Swarm

Why Animals Swarm

Have you ever wondered why insects, birds, fish, and bats gather together into huge and coordinated groups? TED-Ed’s Maria R. D’Orsogna explores the fascinating science behind this behavior, which drives many species as a method of survival and group productivity.
