First, let's get a few things out of the way: In real life, we can't put a metal pole between the Earth and the Moon. It's a little less if you're in the higher region of low Earth orbit. Even. Mt. The song's length leads to an odd coincidence. can climb at over a meter per second in championship competition. This work is licensed under a Creative Commons Attribution-NonCommercial 2.5 License. Off topic discourse and banter encouraged. What if we had a magical pole that dangled from the Moon down to just above the Earth's surface, expanding and contracting so it never quite touched the ground? Transcript [Cueball and Megan sit beside a moonlit lake.] As Ethan mentions, it would need to be pressurized, with an airlock every few miles. But getting to space is easy. People often say, "It's not the fall that kills you, it's the sudden stop at the end." Even more obscure is the question of which point on the Earth's surface moves the fastest as the Earth spins, which is the same as asking which point is farthest from the Earth's axis. posted. [9]Using song beats to help measure the passage of time is a technique also used in CPR training, where the song "Stayin' Alive" is used to . A space probe is an unmanned robotic spacecraft that leaves Earth orbit and explores space.. People can climb poles pretty fast. Cueball: Arthur C. Clarke said space elevators will be built 50 years after everybody stops laughing. Chimborazo in Ecuador, due to the fact that the planet bulges out at the equator. This means you're free to copy and share these comics (but not to sell them). Space Burial. A stairway to space [1] If there's a bustle in your hedgerow, well By XKCD definition, ... You’ll think that there’s space to discuss the validity of [your inflammatory subject]. This work is licensed under a Creative Commons Attribution-NonCommercial 2.5 License. More details.. [15]For aerodynamic reasons, this gear should probably make it look like you're wearing a very fast airplane. Have you ever wondered what would happen if you put a toaster in a freezer? Even if you climb at better-than-world-record speed, it will still take you several years to get to the L1 crossover point. This means you're free to copy and share these comics (but not to sell them). That's far away—I wouldn't want to climb a ladder to get there—but it isn't that far away. I mean, unfortunately in this specific context. (His previous attempt at creating a "New Sports System" for multiplayer socially-distant basketball was not very successful.) Instead of sliding, you'll have to climb. Explanation []. Thanks to heat shields, slowing down is, Yes, I know, orbits are conic sections which in the case of the Moon is. To get into orbit, you need to increase your speed to 8 km/s, which means you'll need a lot of fuel: $ 1.4\times1.4\times1.4\times1.4\times1.4\times1.4\times1.4\times1.4\approx 15$ times the original weight of your ship. You can read this article for an explanation, but the bottom line is that changing your speed by 11 km/s takes either a tank of fuel the size of a building or a tiny heat shield, and the tiny heat shield is a lot easier to carry. The bottom end of the pole makes a much smaller circle in the same amount of time, moving at an average speed of only about 35 mph relative to the center of the Moon's orbit: 35 miles per hour doesn't sound bad. That's far away—I wouldn't want to climb a ladder to get there—but it isn't that far away. It's been over a year since there was a new "xkcd: What If?" Could a (small) rocket (with payload) be lifted to a high point in the atmosphere where it would only need a small rocket to get to escape velocity? However, the glass and water are now moving too fast for the vapor buildup to matter. After another few weeks of gliding along the pole, you'll start to feel gravity take over, speeding you up faster than you can go by pushing yourself.
