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.

The Arctic

If you live somewhere that snow coats roads in the wintertime, you’ll want to check out Engineering Explained’s latest clip, as Jason walks us through the variables at work when driving on slippery surfaces, and provides some tips on how to maintain control on the snow.

What’s a Skyhook?

What’s a Skyhook?

Sending cargo and ships into space is extremely expensive and resource-intensive. But there’s an idea that’s been bandied about that would use endlessly-moving tethers to catapult ships into space from Earth’s orbit. Kurzgesagt explains how this relatively simple concept could dramatically improve space travel.

Life in a Different Light

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 If Earth Had a Second Moon?

What If Earth Had a Second Moon?

The Earth’s lone moon is very important to the way the world works, affecting everything from the ocean tides, to the regularity of our seasons and the length of our days. But what would happen if another similar asteroid got pulled into the Earth’s orbit? SciShow explores some of the potentially serious implications.

Planetary Speed Comparison

Planetary Speed Comparison

If you spent any time paying attention in class, you’d know that every planet spins at a different speed. Scientist and data geek James O’Donaghue put together this nifty visualisation that shows the the relative speed and axial tilt of our Solar System’s planets (and Pluto). We had no idea Jupiter was such a speed demon.

Planetary Blocks

Planetary Blocks

The always awesome Chop Shop Store teamed up with The Planetary Society to create 20 wooden blocks, each featuring a planet, dwarf planet, or moon from our solar system, and printed with useful data. They’re also offering space-themed add-ons like posters, tees, and stickers. Shipping starts 11/2019.

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.

Is Back to the Future Survivable?

Is Back to the Future Survivable?

There’s a lot of stuff that happens to Marty and Doc in Back to the Future, from being blown away by a giant amplifier, to acting as a conductor for a lightning bolt. Jake Roper of Vsauce3 decided to find out if it would be remotely possible to live through all that in this episode of Could You Survive the Movies?

Are We Living in a Simulation?

Are We Living in a Simulation?

There’s no question that we live in a vast and incredibly complex universe. The fact that life exists at all has led some scientists and philosophers to ponder whether or not we are all just living in a computer simulation. This TED-Ed clip by theoretical physicist Zohreh Davoudi and animator Eoin Duffy explores just that question.

Potato Cannon Glider

Potato Cannon Glider

There are thousands of videos out there showing how to make a potato cannon. But this clip from The Backyard Scientist shows how to use one to launch a glider. Working with his pal Joe – with a nod to the guys at FliteTest – they work out the most balanced and airworthy glider design.

The Deadliest Being on Earth

The Deadliest Being on Earth

“There are more phages on Earth than every other organism combined.” Kurzgesagt takes a few minutes to educate us on the finer points of the bacteriophage, a type of virus which is constantly killing off billions of microscopic organisms all around and inside of us.

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.

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.

Bending Light at Home

Bending Light at Home

If you thought the only way to bend a beam of light was with mirrors, you’d be wrong. MEL Chemistry shows off a few simple experiments you can do with a laser pointer and household items like oil, water, and salt, that demonstrate the nature of reflection and refraction. More here.

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.

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.

The Science of BBQ

The Science of BBQ

There’s nothing quite like the delicious flavor of grilled, seared, or smoked meats. But the way you cook and handle meats after cooking can dramatically improve its quality.

If Pangea Never Broke Apart

If Pangea Never Broke Apart

For those of you who were sleeping in class that day, before the earth broke into continents, about 1/3rd of our planet was covered with a landmass known as Pangea. What If attempts to deduce what life might be like if we could still drive from Chicago to Paris, and assuming that we actually evolved to become what we are.

This new channel is a collaboration by SciShow host Hank Green, musician Andrew Huang, and microorganism enthusiast James Weiss. It delves deep into the world of the trillions of microscopic organisms that surround us. We recommend starting off with Meet the Microcosmos for a primer to this fascinating universe.

Flamethrower vs. Aerogel

Flamethrower vs. Aerogel

Aerogel has some amazing properties. It’s insanely lightweight, and is an incredible insulator. Recently, Derek Muller of Veritasium put this to the test, by standing behind a blanket infused with silica aerogel being hit by a Boring Company Not a Flamethrower. Now we’d like to see the same test with a serious flamethrower.
