Did The Future Already Happen? - The Paradox of Time

S12 E01 • Tuesday, Jan 30, 2024 • Jan 30 • 13m

Is your future already written? Do your past, present, and future all exist right now? Surprisingly, the answer could be yes. Let's take a look at what time is and how it works – in our first video of the year!

What Happens AFTER Nuclear War?

S12 E02 • Tuesday, Feb 20, 2024 • Feb 20 • 11m

A nuclear bomb is the most devastating explosion ever created. One bomb can end tens of thousands of lives immediately and hundreds of thousands through the radioactive aftermath. However, the worst part comes afterward: a nuclear winter that might kill billions, potentially leading to the complete collapse of our civilization. In a nuclear winter, there are no winners – only starving losers. How exactly does it work and what would it look like?

The Paradox of an Infinite Universe

S12 E03 • Tuesday, Feb 27, 2024 • Feb 27 • 14m

What is outside of the universe? We know that the universe had a beginning 14 billion years ago and that it has been expanding ever since. But something that is expanding should also have an edge, right? What would you see if you went there?

How The Dinosaurs Actually Died

S12 E04 • Tuesday, Mar 26, 2024 • Mar 26 • 12m

A ruthless murder was committed! Someone killed the dinosaurs and we have the murderer! Witnesses say that an Everest-sized asteroid hit Earth, devastated the planet and caused a mass extinction. A simple, fascinating and convincing explanation. Or… is it?

There Are Thousands of Alien Empires in The Milky Way

S12 E05 • Tuesday, Apr 16, 2024 • Apr 16 • 14m

We often assume that advanced technology will make it easy for aliens to colonize space. But what if space exploration is always difficult, no matter how advanced you are? Let’s travel back in human history, to the colonization of Oceania over 5000 years ago, to find parallels between ancient explorers and extraterrestrial civilizations.

Smoking is Awesome

S12 E06 • Tuesday, May 7, 2024 • May 7 • 12m

We need to have an honest conversation about smoking: The problem with smoking is that it is way more than just a physical addiction. Smoking creates a temporary problem and offers an instant solution. Once your brain is used to nicotine, for up to 72 hours you are itchy,nervous and stressed – but one drag and instantly, you feel really good. It also helps you focus and take breaks during work, while suppressing your appetite. So why is it such a bad idea?

This Black Hole Could be Bigger Than The Universe

S12 E07 • Tuesday, May 21, 2024 • May 21 • 12m

Black holes might create infinite universes while destroying time and space. Everything in existence could be black holes, all the way down. We might live inside a black hole that is inside a black hole, that is inside a black hole. But let’s start at the beginning and build a black hole out of air.

Do You Have a Free Will?

S12 E08 • Tuesday, Jun 11, 2024 • Jun 11 • 13m

You may think you have free will and can choose what you do, but this might be an illusion. Your body is made up of particles that blindly follow the laws of physics, with every outcome already predetermined. So, you might not have any free will at all. Is free will an illusion, or does it exist? Which philosophical camp is right?

This Disease is Deadlier Than The Plague

S12 E09 • Tuesday, Jun 25, 2024 • Jun 25 • 11m

The white death has haunted humanity like no other disease following us for thousands, maybe millions of years. In the last 200 years it killed a billion people – way more than all wars and natural disasters combined. Even today it’s the infectious disease with the highest kill count. But what is this horrible disease?

A.I. ‐ Humanity's Final Invention?

S12 E10 • Tuesday, Aug 6, 2024 • Aug 6 • 18m

Humans rule Earth without competition. But we are about to create something that may change that: our last invention, the most powerful tool, weapon, or maybe even entity: Artificial Super intelligence. This sounds like science fiction, so let’s start at the beginning.

Fever Feels Horrible, but is Actually Awesome!

S12 E11 • Tuesday, Aug 13, 2024 • Aug 13 • 13m

Fever feels bad. So we take medication to suppress it – but is this a good idea? It turns out fever is one of the oldest defenses against disease. What exactly is a fever, and how does it make your immune defense stronger? Should you take a pill to combat it?

We Traveled Back in Time. Now Physicists Are Angry.

S12 E12 • Tuesday, Aug 27, 2024 • Aug 27 • 11m

Time travel is possible. In fact, you’ve been doing it since the day you were born. But what if we told you there’s a way to hack the universe and manipulate time itself? We just have to do two simple things to make it happen: 1. Make a lot of physicists grumpy. 2. Shoot one twin through space against their will, while the other chills on Earth. Let's go!

We Need to Rethink Exercise (Updated Version)

S12 E13 • Thursday, Sep 12, 2024 • Sep 12 • 13m

Exercising doesn’t help you lose weight. In fact, it barely changes your daily calorie burn. Welcome to the workout paradox! Let’s dive into the science of how your body actually handles calories and sabotages your best efforts to burn them.

Why Scientists Are Puzzled By This Virus

S12 E14 • Tuesday, Sep 17, 2024 • Sep 17 • 11m

You’ve got trillions of viruses inside you – right now! But these aren’t the viruses you fear. Some of them are your body’s secret protectors, keeping deadly bacteria in check and even killing cancer cells. But what happens when they turn against you? Let's look at the wild world of the human virome.

This Video Might Save 58 Lives Next Week

S12 E15 • Tuesday, Sep 24, 2024 • Sep 24 • 13m

58 of you watching this video right now will not be alive next week. And it’s not because of some freak accident or rare disease. It’s because of everyday actions you probably think are harmless. Let’s save your life today by looking at what is most likely to kill you next week – so you can avoid it.

There Is Something Hiding Inside Earth

S12 E16 • Thursday, Oct 3, 2024 • Oct 3 • 12m

We’ve found a new planet, home to octillions of the most extreme beings living in the most absurd and deadly hellscape. In absolute darkness, crushed by the weight of mountains, starved of oxygen, cooked alive, bathed in acid, salt or radiation. And yet, they live for thousands, perhaps millions of years! It turns out, this planet is not in space – it is inside the crust of Earth! This is the deep biosphere and we basically learned that it exists yesterday. Its volume is at least twice as large as all the Earth’s oceans, home to more microbes than the rest of the entire planet.Their total biomass is more than 20 times greater than all humans, livestock, and animal wildlife. Let’s descend into this mad, deadly world where none of the rules we thought are mandatory for life apply.

Tired of Doomscrolling?

S12 E17 • Tuesday, Oct 8, 2024 • Oct 8 • 11m

Being a human in the 21st century often feels frustrating. We are clearly at the high point of our species, while at the same time life is incredibly hard! We are divided, unable to solve our problems while creating new ones, destroying our world in the process. In many ways the vibe is that we live in dark times. But as Terry Pratchett said, we are the storytelling ape, we think in narratives and live in a network of stories that make up our world. So without minimizing the darkness, we want to add a story that we find helpful for dealing with the world.

We Fell For The Oldest Lie On The Internet

S12 E18 • Tuesday, Oct 29, 2024 • Oct 29 • 13m

“Your blood vessels stretch a staggering 100,000 kilometers, enough to wrap around Earth twice!" Sounds amazing, right? We spent over a year trying to confirm this claim, and let's just say – things aren't as they seem. Join us on our year-long journey that uncovered outdated science, speculation, and a lot of dead ends.

The Most Insane Weapon You Never Heard About

S12 E19 • Tuesday, Nov 5, 2024 • Nov 5 • 14m

At the height of the Cold War, a terrifying concept emerged: a bomb so powerful it wouldn’t need to be dropped. Known as Project Sundial, this doomsday device would have left a 400-km radius in flames and plunged the world into darkness. It was a bomb that would destroy everything – not a weapon, but an apocalypse. How close did we come to pressing the button?

We Have To Talk About Weed

S12 E20 • Tuesday, Nov 12, 2024 • Nov 12 • 15m

Cannabis is finally being decriminalized in more and more places around the world. And for very good reasons! Compared to other legal drugs such as alcohol, cannabis is pretty mild and most users enjoy it without issue. But there’s a dark side for some. So let’s take an honest look at some of the latest research together.

Vaping Is Too Good To Be True

S12 E21 • Tuesday, Nov 19, 2024 • Nov 19 • 14m

Vaping is marketed as the “safe” alternative to smoking, but it’s far from being harmless. Unregulated ingredients, hidden toxins, and extreme nicotine levels mean we’re conducting a massive experiment on ourselves. Let’s dive into what we know – and what we don’t know, yet.

Black Hole's Evil Twin - Gravastars Explained

S12 E22 • Tuesday, Dec 3, 2024 • Dec 3 • 14m

Gravastars could change how we think about the universe. These cosmic objects solve black holes’ biggest problems without breaking physics. From their ultra-thin shell to their energy-filled core, gravastars are both elegant and terrifying. But what exactly are they?

Is The World Getting More Violent?

S12 E23 • Tuesday, Dec 10, 2024 • Dec 10 • 13m

Ten years ago, in 2014, we released a video titled "Is War Over?". Back then, the question didn’t seem so naive. It seemed violent conflict was on the decline and the world more peaceful than ever. But the last ten years weren’t what we expected. So let's see how our video has held up.

The Real Reason Why You Have Allergies

S12 E24 • Thursday, Dec 12, 2024 • Dec 12 • 15m
