Could We Create A Bottomless Pit On Earth?

EXCERPT: . . . The Earth's outer core becomes liquid and molten, and the inner core is highly radioactive, with temperatures in excess of 4000 °F (2200 °C). This is so spectacularly hot that it would literally melt, boil or sublimate practically any known materials. So what we'll need to create is something that will stabilize your cylindrical shaft going right through the Earth’s center. Graphene, a particular form of carbon bound together, might be an excellent candidate, as it's harder and more difficult to break than even diamonds. Graphene can be created in the form of carbon nanotubes, which themselves are hollow on the inside. This could be created to not only line the walls of your bottomless pit, but if you can sufficiently cool them, they'll be capable of holding back the interior layers of the Earth. Pumping and circulating an ultra-cold liquid through a graphene nanotube, like liquid helium, just might do the trick.

If you can create a stable tunnel all the way through the Earth, you will have created a true bottomless pit. A journey through this pit would make the world’s longest skydive look like a paltry coin-toss. [...] a journey through a bottomless pit would take you more than 12,000 km, all the way from one side of the Earth to the other. Only, if you jumped like a skydiver, whether with or without a parachute, you wouldn't get very far along your journey. [...] The entire Earth rotates with the same angular velocity, but like a record spinning on a turntable, the interior parts have a lower linear velocity than the outer parts, meaning someone falling through the Earth would inevitably run into the sides. [...] There’s a workaround, however, if you’re clever. [...]

As you fall through a pit connecting Earth's surface to the center, you'll continue to accelerate faster and faster so long as there's no medium inside the pit to resist your motion, until you reach your maximum speed at the center of the Earth. [...] reaching a maximum speed at the very center-of-Earth of over 11,000 meters-per-second, which is around 40,000 km/hr or 25,000 mph. The journey, through an airless shaft to the center of the Earth, only takes about 22 minutes, with some uncertainties in there based on the densities of different layers. In addition, because there’s no air resistance, no energy is lost.

Once you passed through the Earth's center at that blinding speed, you'd slow down as you progressively moved away from the Earth’s core and through the various outer layers. Your acceleration would change as you moved as well [...] After a total of 45 minutes after you were dropped into the shaft from the North Pole, you’d emerge from the South Pole. Only, because the South Pole is at an elevation of around 2,800 meters (over 9,000 feet), you’d barely be able to see daylight overhead before you came to a halt, and then had the identical journey back from whence you came....
