The Earth might not be here forever. A huge solar flare, an asteroid impact, or a local gamma-ray burst — anything could wipe us out for good.

If we're looking for someplace to escape to, there is one planet in our Solar System that is somewhat similar to Earth, though we don't know much about it. It might even be hosting some microbial life. No, it's not Mars — it's Venus.

A marshmallow meteorite hurtling straight toward Earth? How would this sweet space object begin its descent toward our planet? Would the rapid speed of 99.9% of the speed of light, which is 299,792 km/s (186, 282 mps), cause the marshmallow to disintegrate in mid-air?

What would happen if a marshmallow traveling at light speed actually made contact with Earth?

What's the first thing you should do if you ever fall into a pool full of stingrays? They may look super cute, but don't let their friendliness fool you.
Because they're also carrying a long, venomous, serrated stinger that could kill you at any moment. So should you swim out of there as fast as you can? Or stay close to the surface of the water? Or should you just dance on the bottom of the pool?

You may think of it as something that helps you communicate with
your friends, laugh at memes, and binge-watch your TV shows. Others might think of it as a way to make money, perform illegal activities, and maybe even spread propaganda. Regardless of how you use it, the internet is arguably the most powerful tool in the world. So what would happen if you controlled it? How powerful would you be? What websites would you control? And could this actually happen?

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?

Populations of people are already fleeing climate change across the globe. In North America, the Alaskan village of Newtok was faced with a mega slump caused by melting permafrost. As the layers of frozen soil melted, the ground became unstable. Homes started to sink and crumble. Coastal cities across the globe are planning how they will keep the sea away as it rises. One solution? Just move the city. How much would it cost? How do you lift a building? Where is this already happening? How severe can coastal flooding be?

How cool would it be to see a real life T-Rex? If only that one fatal asteroid never hit Earth.

Would dinosaurs still be alive today? Would they have evolved? Would humans have survived this long? Could we ever learn to co-exist?

Until 66 million years ago, dinosaurs of all shapes and sizes roamed the Earth. Intelligent, adaptable, and sometimes weighing as much as two jetplanes, it’s hard to believe that it only took one rock to wipe them all out. Of course, this was no ordinary rock.

Billions of years ago, another planet smashed into Earth. An event of this epicness could have created our Moon. It also could have brought alien life to our planet. What evidence of this planet still exists on Earth today? Could there be life deep inside the Earth’s surface? And could that life be an advanced civilization of humanoid aliens? Would it be possible for subterranean cities to exist within Earth?

If we found out that Earth only had 10 years left before it was destroyed, we'd need to figure out a plan for humanity to survive. And with a global population of 7.8 billion people, our survival plan would have to be as colossal as possible. How could we evacuate? What resources would we need to take to survive? And where would we go?
