# Drain the Oceans

Found this the other day, I'm sure you'll like it.

How quickly would the ocean's drain if a circular portal 10 meters in radius leading into space was created at the bottom of Challenger Deep, the deepest spot in the ocean? How would the Earth change as the water is being drained?

I want to get one thing out of the way first:

According to my rough calculations, if an aircraft carrier sank and got stuck against the drain, the pressure would easily be enough to fold it up[1] and suck it through. Cooool.

Just how far away is this portal? If we put it near the Earth, the ocean would just fall back down into the atmosphere. As it fell, it would heat up and turn to steam, which would condense and fall right back into the ocean as rain. The energy input into the atmosphere alone would also wreak all kinds of havoc with our climate, to say nothing of the huge clouds of high-altitude steam.

So let's put the ocean-dumping portal far away—say, on Mars. (In fact, I vote we put it directly above the Curiosity rover; that way, it will finally have incontrovertible evidence of liquid water on Mars's surface.)

What happens to the Earth?

Not much. It would actually take hundreds of thousands of years for the ocean to drain.

Even though the opening is wider than a basketball court, and the water is forced through at incredible speeds,[2] the oceans are huge. When you started, the water level would drop by less than a centimeter per day.

There wouldn't even be a cool whirlpool at the surface—the opening is too small and the ocean is too deep.[3] (It's the same reason you don't get a whirlpool in the bathtub until the water is more than halfway drained.)

But let's suppose we speed up the draining by opening more drains. (Remember to clean the whale filter every few days), so the water level starts to drop more quickly.

Let's take a look at how the map would change.

Here's how it looks at the start:

Every country would become like Russia, always going to war from fear of being invaded by land.

I think it would cause the earth to wobble as it spins due to loss of weight at the drain.

Yeah, that's something I thought about.

Wouldn't the crust move around because it's no longer pushed down, by the water's weight?

I think the ocean floors are thinner and might rupture as water pressure declines. Promoting more volcanic activity.

The Earth would just slowly turn into Mars II.

Then maybe in a few billion years,
someone will send a rover to explore the dead husk for signs of life where crazy things like
smart phones....laptops....drone propellers....and other things might be found and
argued against as just mere pareidolia illusions.

Wouldn't that be wild??
