The next step in space exploration isn't generations away. It's happening right now. And our destination? That mysterious, desolate world next door, Mars. Imagine starting life over on that tiny red dot over 265 million km (16.5 million mi) away. What would happen if we built a city on Mars? Would you have to live underground? How many people would you live with? And, what would the Martian economy look like? What does regolith have to do with living on Mars? How would radiation shielding be built?

Contrary to what some people think, the Earth isn’t the center of the Universe. But what if it was? What if those medieval astronomers were right, and everything does revolve around you? How would this change what we know about the Sun? In what ways would the other planets move around us? And how would this affect your everyday life? What if the geocentric model of the solar system was true? Instead, what if the heliocentric model was false?

It's a small world after all, because today, we're shrinking Earth to the size of Pluto. But if our planet was this tiny, how would it alter the atmosphere? Why would the Earth get hotter?

Russian president Vladimir Putin and Chinese leader Xi Jinping have a positive relationship for now. But as Russia goes to war with Ukraine, what would happen if the Chinese invaded Russia?

The Chinese army has over 2 million troops, double Russia’s military force. But Russia has more nukes. And neither of these turbulent countries have seen war in years. What would happen if China invaded Russia?

What could turn China against Russia? How would it impact Russia’s already- low resources from the war in Ukraine? And what would happen if this war went nuclear?

When the Earth woke up from an ice age, the Paleozoic Era began. This era lasted for 289 million years, but you might not even last five minutes in a Paleozoic climate.

For billions of years, the Sun's gravitational pull has kept Earth's orbit on a steady and reliable path. But this rogue star has other plans for our planet. This sudden shift in Earth's gravity would make our planet break away from orbiting the Sun. And now, for the first time in our planet's history, we would be drifting through space without any direction. How fast would Earth travel? Could we survive the extreme temperatures of space? And could the Earth fly through the asteroid belt?

If laws didn't govern our world, would you still know the difference between right and wrong? If you desperately need food or shelter, what stops you from just stealing it from someone else? Well, humans are one of the only members of the animal kingdom that have empathy, and it's the main thing keeping us from tearing each other apart. So how would we survive without it? Would we be living in a world full of psychopaths?

"Imagination will often carry us to worlds that never were. But without it, we go nowhere." — Carl Sagan

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.

No one can say with certainty what happens after we die. And it's the one unknown all of us will face. So what if our existence wasn't temporary? What if there was life after death? How long can your brain live after your body dies? Could your loved ones still communicate with you? And does your body contain the zombie gene? Is death a figment of your imagination? What's our perception of reality on it?

Mars didn’t always look like this. It may have once been covered in oceans. But what if we brought all the Martian water back and transformed the red planet into one that’s half blue?

A blue whale's blowhole is so large that a baby could fit inside it. Like you and me, whales have lungs. They don’t have gills though, so they can’t breathe underwater. But unlike us, whales can hold their breath for a long time. How powerfully can a whale exhale? What would happen to the whale? Would you be able to escape?

A volcano is one of the most unforgiving natural phenomenons on Earth. If you were to fall into its magma-filled center, your body would quickly bubble up, and disappear without a trace. So if they're so good at getting rid of things, why aren't we using them to get rid of our garbage? Has anyone tried it before? How would we transport all our trash to them?

In the beginning, there was nothing. Then bang. Our Universe emerged in an explosion of light and energy. Current theories say that it all began 13.7 billion years ago. Or did it? Let's shed some light on this. So, how fast is the Universe expanding? Will the Universe and everything in it ever die? And why could our Universe have existed before the Big Bang? What's a singularity?

You chew it. You stretch it. You blow it. And, be honest, sometimes you stick it on things. But what happens to your body when you swallow chewing gum? And, not just once but all the time? If you always swallow your gum, could it plug up your body? Is it true that it could kill you? What does chewing gum do to your digestive system? Could it cause sepsis? Are your intestines in danger? How is the sapodilla tree related to chewing gum?

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?

Forget a doomsday asteroid or melting permafrost. It’s the freezing of Earth’s core that will end the world in today’s episode. Or would it? Because maybe, just maybe, we could save the world by heating Earth from the inside. What is happening down in the Earth’s core? What would happen if the core froze completely? And would we have a chance of fixing the Earth before it’s too late? What will happen to Earth's magnetic field? What is a superhot core?

#WhatIf #HeatingEarth #MoltenCore #SuperhotCore #MagneticField

Hundreds of meters underground. Large enough to house tens to hundreds of thousands of people. And walls strong enough to withstand the force of a nuclear blast. These are some of the world's deepest, and largest bunkers. But even in an apocalypse, you wouldn't be completely safe in one of these. Earth-penetrating weapons, like the 1.2 megaton B83 warhead, can demolish bunkers 300 m (1,000 ft.) deep. What would it take to build a deeper bunker? What would life be like inside it? And why can living underground be dangerous?
