Some of the planets in our Solar System are gigantic. But what if they got even bigger? Let’s go up the planetary size chart and see what kind of chaos doubling the size of every planet would make. What would it be like to live on a super-Earth? How big would Jupiter need to get to become a star? And would Pluto finally regain its planetary status?

Jupiter may be the biggest planet in the Solar System, but its days are numbered. Because today, we’re using Earth’s biggest, baddest bombs to blow the gas giant into oblivion. How many nukes would you need to do the job? What obstacles would these rocket-bound bombs encounter on the way? Would one nuclear explosion ignite the entire planet? What are Kirkwood gaps?

We’re in an age when many outside forces could be spying on you. Your phone, your social media apps, but what about… birds? Theoretically, could the birds that fly around us in the sky be government surveillance drones? It sounds far-fetched, but in a time where your data is far more accessible than you think, your personal information just might be for the birds.

What if we found the way to drain all the Earth's oceans through some mysterious portal at the bottom of the Mariana Trench? How long would it take? Years? Centuries? Millennia? Would there be any life left on Earth when the pumping was over? What if it happened overnight?

Oceanic water makes up 70% of the Earth’s surface. If we opened a portal about the size of a basketball court, it would take us hundreds of thousands of years to pump out the oceans. They hold over a billion cubic km (321 million cubic miles) of water. But what if we had a pump powerful enough to drain all the oceans in a minute? What would happen then?

It lived millions of years ago, but let's assume this monster shark was alive today. And instead of worrying about other creatures in the sea, this megalodon is now coming for you. How would the megalodon hunt you down? How could your size be your best advantage? And could you survive this attack?

This pretzel-shaped collection of galaxies is our Universe. And it's about to collide with another universe. It might be fascinating to watch, but we should probably be worried about what's going to happen when they crash. How would it change the physics of our Universe? Is there any chance that we would survive? What would the collision look like from Earth? And has it ever happened before?

Would there be a massive drought? How severe would the droughts be?
