It's famously been said that we know more about the surface of the Moon than we do about the bottom of our ocean, so challenging are the conditions in the true depths of our deepest seas.
Well, that might be a concept that can be hard to get your head around, especially if you don't really have a sense of just how incredibly deep our oceans actually get.
Thankfully, a brilliant YouTube video helps with that problem hugely. It's from MetaBallStudios, who specialise in visualisations and scale comparisons, and is a 3D rendering that shows a scale of how deep oceans are.

It starts off showing a deepening ocean with markers to describe the depths of familiar elements like the Eurotunnel or the wreck of the RMS Lusitania, which sunk in 1915.
Pretty soon, though, we're descending to depths equivalent to the entire Eiffel Tower (324 meters) and further, to see how deep the bottom of North America's Lake Superior is, for example, at 406 meters.
It's a staggering watch, and has people in the comments underneath getting a bit loopy with how big the scale is.
One person noted: "I cant describe the anxiety this stuff gives me but I can't stop watching."
Another agreed: "Videos like this really show how much like ants we really are in the big scope of not only the planet but the universe at large too".
There are elements you definitely didn't know about if you're like us, too - such as the enormous Petronius oil platform in the Gulf of Mexico, which has its foundations at an impressive 565 meters down.
By the time you can submerge the entirety of the Burj Khalifa under the surface, the world's tallest building at 829 meters, you know we're dealing with real depth.
The Caspian Sea is deeper still, at 1025 meters, and the Black Sea's average depth outdoes that at 1253 meters, but even the calm-seeming Mediterranean Sea is around 1500 meters deep on average.
It's amazing when something man-made still enters the video, though, like the Perdido oil platform, which runs pipes down to a wild 2450 meters (8040 feet) deep to extract oil.
The shipwreck we've all been waiting for, the RMS Titanic, pops up at 3700 meters deep, which is just around the average depth of the Atlantic Ocean, making its discovery all the more impressive.
From here the numbers accelerate further, with the maximum depths of oceans like the Mediterranean Sea and Arctic Ocean both in excess of 5200 meters.
There are still shipwrecks that we know about even at depths of 6500 meters, like the USS Johnston, and when we pass 8848 meters deep the video handily points out that we're now deeper below the surface than Everest's peak is high above it, which is crazy.
The video ends with the first crewed mission to the ocean's floor, the Trieste - which got to 10,911 meters deep, just a shade below the true bottom of the Mariana Trench at around 11,000 meters.
