The Burj Khalifa

If you turned Mount Everest upside down and dunked it in the ocean its tip would still be over a like 3,000 feet from the bottom of the Marianas trench. Being even remotely in the ocean gives me the heebie jeebies. I really like that there's a zone called the abyss and then the trench is like way lower than the abyss. You can see it about as easily as you can see the space station.
