Deep under the crust and mantle of our Earth lies its core. Earth’s core was formed during the Iron Catastrophe, a major geological event where Earth was heated to temperatures above iron’s melting point. Would a coreless Earth even be sustainable? Could humans live on an Earth with no core? And what kind of environment would we see on this type of Earth?

Have you ever wondered what dinosaurs were afraid of? What creature, in the Cretaceous period, made taking a drink of water a dangerous gamble? I'm talking about terror crocs. No, no, not those crocs. Deinosuchus, otherwise, known as The Terror Crocodile. What made terror crocs such extreme predators? If they were still around, what would threaten their survival today? Were they able to eat dinosaurs, bones and all?

There is no mistaking the 15 cm (6 in) teeth of the largest apex predator, the megalodon. Getting bitten by this beast would feel like being crushed by three African elephants stacked on top of each other. What could this apex predator be hunting in the deep? How could it withstand the immense pressure? And how would the Mariana Trench make this apex predator more docile?

What If is a mini-documentary web series that takes you on an epic journey through hypothetical worlds and possibilities. Join us on an imaginary adventure — grounded in scientific theory — through time, space and chance, as we ask what if some of the most fundamental aspects of our existence were different.

These nasty little bloodsuckers have sunk their razor-sharp mouths into you for the last time. Today we're killing every tick on Earth. But how would you trap them? Why would we have to modify their DNA? And how could this destroy whole ecosystems?

00:00 What If We Killed All Ticks?
01:27 How would we get rid of every tick?
02:51 What if we got other animals to do the work for us?
03:18 How would this affect public health?

It's the largest star that we've ever discovered. And if it were to replace our Sun, it would change a lot more than just the amount of sunscreen you'd have to put on. Like, how long would it take for our planet to orbit this massive star? What would that do to our seasons? And would we even survive a single orbit?

Do you know what you’re putting on your skin? Makeup can highlight your best features, smooth out imperfections, and help you feel confident. And sometimes, you’re just too tired to wash it off before you go to bed. You could get away with this for one night without causing too much damage. But what if one night turns into two, then three, then four, and then 100 days go by, and you still haven’t taken your makeup off? What would you look like? Can makeup cause acne? Or cancer?

We’ve thrown a lot of disasters at Earth over the years: from asteroids and aliens, to the Sun's death. But hey, the Universe is a dangerous place, and we’re not done yet. Now we’re going to throw a black hole into the mix, and not just any black hole, but a blazar. Black holes are usually found at the center of the galaxy. The Milky Way has a black hole that is four million times the mass of the Sun. But that’s small compared to other black holes out there. How old is the oldest blazar? Why can we see some blazars, but not others? What is the Doppler effect and how would it let us know that a blazar is on its way? What are active galactic nuclei? Do radiation and gamma rays from blazars affect the Earth? How far is Markarian 421 from us?

Monday. Tuesday. Wednesday. Wednesday. Wednesday. Again? Wednesday. I feel like we've done this before. Wednesday. Does anybody else notice this? Wednesday. How do I break this time loop? Could you tell if you've been living the same day all over again? How many times did today really happen? And if you were trapped in a loop, how would you get out of it?

They’re in your yard, on your walls, in your attic, and there’s probably one near you right now. The thought of these creepy crawlers might make you want to go on an immediate spider crusade. With global numbers in the quadrillions, it would be 2.8 million spiders versus every human. My bet is on the spiders. Maybe with a large-scale international effort, spiders could be eradicated. Just imagine a spider free world! What would happen to other bugs? Would we see an increase in disease? How would it change the future of medicine?

No, that’s not Photoshop. That’s an actual video from the International Space Station of the Moon looking a bit squished. Is the cover-up behind a flat Moon an elaborate government conspiracy? How would this affect the oceans? What would happen to our climate? And could the Moon fly out into space?

Freezing cold, dark and with an atmosphere that smells like farts and rotten eggs? Uranus doesn’t sound like somewhere you’d want to call home. But let’s say you did want to move to Uranus. What kind of home settlement would you need to build? And what dangers would you encounter on the stinkiest planet in the Solar System?

You know what might be the best way to travel to the other side of the world? By drilling your way right through the planet. Imagine going from Argentina to China in less than an hour. This would be the journey of a lifetime, if you don't mind riding through molten rock and crushing pressure. What would you see along the way? How long would this journey through Earth take?
