Earth-Moon Fire Pole

by xkcd

My son (5y) asked me today: If there were a kind of a fireman's pole from the Moon down to the Earth, how long would it take to slide all the way from the Moon to the Earth?

Ramon Schönborn, Germany

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.[1] The end of the pole near the Moon would be pulled toward the Moon by the Moon's gravity, and the rest of it would be pulled back down to the Earth by the Earth's gravity. The pole would be torn in half.

Another problem with this plan. The Earth's surface spins faster than the Moon goes around, so the end that dangled down to the Earth would break off if you tried to connect it to the ground:

There's one more problem:[2] The Moon doesn't always stay the same distance from Earth. Its orbit takes it closer and farther away. It's not a big difference,[3] but it's enough that the bottom 50,000 km of your fire station pole would be squished against the Earth once a month.

But let's ignore those problems! 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? How long would it take to slide down from the Moon?

If you stood next to the end of the pole on the Moon, a problem would become clear right away: You have to slide up the pole, and that's not how sliding works.

Instead of sliding, you'll have to climb.

People can climb poles pretty fast. World-record pole climbers[4] can climb at over a meter per second in championship competition.[5] On the Moon, gravity is much weaker, so it will probably be easier to climb. On the other hand, you'll have to wear a spacesuit, so that will probably slow you down a little.

If you climb up the pole far enough, Earth's gravity will take over and start pulling you down. When you're hanging onto the pole, there are three forces pulling on you: The Earth's gravity pulling you toward Earth, the Moon's gravity pulling you away from Earth, and centrifugal force[6] from the swinging pole pulling you away from Earth.[7] At first, the combination of the Moon's gravity and centrifugal force are stronger, pulling you toward the Moon, but as you get closer to the Earth, Earth's gravity takes over. The Earth is pretty big, so you reach this point—which is known as the L1 Lagrange point—while you're still pretty close to the Moon.

Unfortunately for you, space is big, so "pretty close" is still a long way. Even if you climb at better-than-world-record speed, it will still take you several years to get to the L1 crossover point.

As you approach the L1 point, you'll start to be able to switch from climbing to pushing-and-gliding: You can push once and then coast a long distance up the pole. You don't have to wait to stop, either—you can grab the pole again and give yourself a push to move even faster, like a skateboarder kicking several times to speed up.

Eventually, as you reach the vicinity of the L1 point and are no longer fighting gravity, the only limit on your speed will be how quickly you can grab the pole and "throw" it past you. The best baseball pitchers can move their hands at about 100 mph while flinging objects past them, so you probably can't expect to move much faster than that.

Note: While you're flinging yourself along, be careful not to drift out of reach of the pole. Hopefully you brought some kind of safety line so you can recover if that happens.

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. When this happens, be careful—soon, you'll need to start worrying about going too fast.

As you approach the Earth and the pull of its gravity increases, you'll start to speed up quite a bit. If you don't stop yourself, you'll reach the top of the atmosphere at roughly escape velocity—11 km/s[8]—and the impact with the air will produce so much heat that you risk burning up. Spacecraft deal with this problem by including heat shields, which are capable of absorbing and dissipating this heat without burning up the spacecraft behind it.[9] Since you have this handy metal pole, you can control your descent by clamping onto it and controlling your rate of descent through friction.

Make sure to keep your speed low during the whole approach and descent—and, if necessary, pausing to let your hands or brakepads cool down—rather than waiting until the end to try to slow down. If you get up to escape velocity, then at the last minute remember that you need to slow down, you'll be in for an unpleasant surprise as you try to grab on to the pole. At best, you'll be flung away and plummet to your death. At worst, your hands and the surface of the pole will both be converted into exciting new forms of matter, and then you'll be flung away and plummet to your death.

Assuming you descend slowly and enter the atmosphere in a controlled manner, you'll soon encounter your next problem: Your pole isn't moving at the same speed as the Earth. Not even close. The land and atmosphere below you are moving very fast relative to you. You're about to drop into some extremely strong winds.

The Moon orbits around the Earth at a speed of roughly one kilometer per second, making a wide circle[10] every 29 days or so. That's how fast the top end of our hypothetical fire pole will be traveling. 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. Unfortunately for you, the Earth is also spinning,[11] and its surface moves a lot faster than 35 mph; at the Equator, it can reach over 1,000 miles per hour.[12]​[13]

Even though the end of the pole is moving slowly relative to the Earth as a whole, it's moving very fast relative to the surface.

Asking how fast the pole is moving relative to the surface is effectively the same as asking what the "ground speed" of the Moon is. This is tricky to calculate, because the Moon's ground speed varies over time in a complicated way. Luckily for us, it doesn't vary that much—it's usually somewhere between 390 and 450 m/s, or a little over Mach 1—so figuring out the precise value isn't necessary.

Let's buy a little time by trying to figure it out anyway.

The Moon's ground speed varies pretty regularly, making a kind of sine wave. It peaks twice every month as it passes over the fast-moving equator, then reaches a minimum when it's over the slower-moving tropics. Its orbital speed also changes depending on whether it's at the close or far point in its orbit. This leads to a roughly sine-wave shaped ground speed:

Well, ready to jump?

Ok, fine. There's one other cycle we can take into account to really nail down the Moon's ground speed. The Moon's orbit is tilted by about 5° relative to the Earth-Sun plane, while the Earth's axis is tilted by 23.5°. This means that the Moon's latitude changes the way the Sun's does, moving from the northern tropics to the southern tropics twice a year.

However, the Moon's orbit is also tilted, and this tilt rotates on an 18.9-year cycle. When the Moon's tilt is in the same direction as the Earth's, it stays 5° closer to the Equator than the Sun, and when it's in the opposite direction, it reaches more extreme latitudes. When the Moon is over a point farther from the equator, it has a lower "ground speed," so the lower end of the sine wave goes lower. Here's the plot of the Moon's "ground speed" over the next few decades:

The Moon's top speed stays pretty constant, but the lowest speed rises and falls with an 18.9-year cycle. The lowest speed of the next cycle will be on May 1st, 2025, so if you want to wait until 2025 to slide down, you can hit the atmosphere when the pole is moving at only 390 m/s relative to the Earth's surface.

When you do finally enter the atmosphere, you'll be coming down near the edge of the tropics. Try to avoid the tropical jet stream, an upper-level air current which blows in the same direction the Earth rotates. If your pole happens to go through it, it could add another 50-100 m/s to the wind speed.

Regardless of where you come down, you'll need to contend with supersonic winds, so you should wear lots of protective gear.[15] Make sure you're tightly attached to the pole, since the wind and various shockwaves will be violently battering and jolting you around. People often say, "It's not the fall that kills you, it's the sudden stop at the end." Unfortunately, in this case, it's probably going to be both.[17]

At some point, to reach the ground, you're going to have to let go of the pole. For obvious reasons, you don't want to jump directly onto the ground while moving at Mach 1. Instead, you should probably wait until you're somewhere near airline cruising altitude, where the air is still thin, so it's not pulling at you too hard—and let go of the pole. Then, as the air carries you away and you fall toward the Earth, you can open your parachute.

Then, at last, you can drift safely to the ground, having traveled from the Moon to the Earth completely under your own muscle power.

(When you're done, remember to remove the fire pole. That thing is definitely a safety hazard.)

[1] For one, someone at NASA would probably yell at us.

[2] Ok, that's a lie—there are, like, hundreds more problems.

[3] You may occasionally see people get excited about the "supermoon," a full Moon that appears slightly larger because it happens at the time of the month when the Moon is closest to Earth. But really, the full Moon always looks surprisingly large and pretty when it's near the horizon, thanks to the Moon illusion. In my opinion, it's worth going outside and looking at the Moon whenever it's full, regardless of whether it's super or not.

[4] Of course there's a world record for pole climbing.

[5] Of course there are championship competitions.

[6] As usual, anyone arguing about "centrifugal" versus "centripetal" force will be put in a centrifuge.

[7] At the distance of the Moon's orbit and the speed it's traveling, centrifugal force pushing away is exactly balanced by the Earth's gravity—which is why the Moon orbits there.

[8] This is why anything that falls into the Earth hits the atmosphere fast enough to burn up. Even if an object is moving slowly when it's drifting through space, when it gets close to the Earth it gets accelerated up to at least escape velocity by that final segment of the trip down into the Earth's gravity well.

[9] People often ask why we don't use rockets to slow down, to avoid the need for a heat shield. 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. Thanks to heat shields, slowing down is much easier than speeding up—which requires the aforementioned giant fuel tank. (For more on this, see this What If question).

Heat shields only work for slowing down; if there were a way to use the same heat shield mechanism to speed up, space travel would get a lot easier. Sadly, no one's figured out a practical way to build a "reverse heat shield" rocket. However, while the idea seems silly, in a sense it's sort of the principle behind both Project Orion and laser ablation propulsion.

[10] Yes, I know, orbits are conic sections which in the case of the Moon is technically not exactly a circle. It's actually a pentagon.

[11] I mean, unfortunately in this specific context. In general, the fact that the Earth spins is very fortunate for you, and for the planet's overall habitability.

[12] It's common knowledge that Mt. Everest is the tallest mountain on Earth, measured from sea level. A somewhat more obscure piece of trivia is that the point on the Earth's surface farthest from its center is the summit of Mt. Chimborazo in Ecuador, due to the fact that the planet bulges out at the equator. 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. The answer isn't Chimborazo or Everest. The fastest point turns out to be the peak of Mt. Cayambe, a volcano north of Chimborazo. And now you know.

[13] Mt. Cayambe's southern slope also happens to be the highest point on Earth's surface directly on the Equator. I have a lot of mountain facts.

[15] For aerodynamic reasons, this gear should probably make it look like you're wearing a very fast airplane.

[17] If it helps, people have survived supersonic ejections before—and even a supersonic aircraft disintegration—so there's hope.

The Ultimate Review About the FreeEssayWriters.net: What You Should Know?

Student life can be the best or worst period of your life. This is the time when you seek your place in the sun, make new friends, broaden your horizons, and develop skills that will help you build a successful career. But this is also a period when you sleep and eat poorly since professors constantly give you a massive amount of homework. Every day you have deadlines, and you need to follow them if you don’t want to ruin your academic performance.

The main thing is to remember that you can ask for help at any time. It doesn’t matter if you are tired, feel a lot, do not consider a specific task attractive or a priority, etc. If you understand that you need support, you can use one of the writing companies’ services.

I offer you an honest review of Freeessaywriters as it is prevalent, and many students ask themselves: is FreeEssayWriters legit? Let’s find out how trustworthy it is.

What do we already know about the FreeEssayWriters company?

What do us know about this company? It is a professional writing service registered in London, UK. If you check their website, you will find enough information about who they are and what they offer. It is the right strategy from their side because they tell new visitors about their successes from the early beginning. And now I know that Freeessaywriters service has:

  • 97% average quality score;
  • 95% happy customers;
  • 99% of orders delivered without delays;
  • 93% report better academic performance.

It sounds really impressive!

However, it is not enough to read how the company positions itself. I’ve explored their website and even made an order to get the paper and answer your question: Is FreeEssayWriters safe?

Types of papers company works with

It is essential to understand what services the company provides. Imagine you need high school essays, but the writing service works exclusively with college and university papers. This is not what you expect when the deadline is a few days away.

Modern writing companies offer a diverse range of services to keep their clients coming back for more. For example, today, you are ordering an essay, but you need a business plan or article review next week. Why should you look for several companies, analyze information about them, and so on, if you can find the best one and become its regular customer?

The FreeEssayWriters provides various writing services: order research paper, personal statement, biography, case study, dissertation, etc. I am talking about both writing and editing and proofreading services.

There are also several free opportunities, such as samples, topics, templates, etc.

My score on this criterion is 10 out of 10.

Authors’ team

When you order paper, you expect to receive an experienced professional who will provide you with excellent results. The writing team is the cornerstone of any writing company, as it is responsible for the final paper, and therefore for the client’s satisfaction.

It doesn’t matter how beautiful the website is, the affordable prices, and the friendly customer support managers if your author is downright weak.

So what about the FreeEssayWriters.net? I’ve highlighted several criteria that help them find their writers:

  • Each author is a degree holder;
  • All FreeEssayWriters writers are native English speakers;
  • Each author should complete a series of tests.

There are also additional criteria, such as a passion for writing, research skills, professional expertise, etc.

I can say that a real expert wrote my paper. I was even surprised by how clear, structured, engaging, and argumentative it was. The author has conducted research to find and analyze information. Of course, the paper was free of mistakes and plagiarism. I am satisfied with the final result.

My score is 10 out of 10.

Website’s design & usability

It would be a mistake to choose a writing company based on design. But not taking it into account is also wrong, so I included this criterion in our review.

And if you visit the page, you will see that it is worth it. There are many similar writing services today that do not differ in any way from their competitors. The FreeEssayWriters stands out because it has taken care of the stylish and modern design.

FreeEssayWriters.net looks not only beautiful but also very comfortable. You can easily find any information you need, find out prices, check FreeEssayWriters reviews, place an order, etc. If you are working with a website and you see that you have to work hard to find this or that section, their services will most likely be so complicated.

The FreeEssayWriters website is beautiful, fast, and easy to use. My verdict is 10 of 10.

Submitting the order

When it comes to checkout, the process must take a minimum of effort. The good news is that this company offers a truly positive experience.

Once you decide to place your order, click the big ‘Hire a Writer’ button. It is impossible not to notice it on the page. You will be redirected to the order form, where you need to specify your task’s main details and requirements. This is your academic level, type of paper, number of sources, topic (you can entrust the choice to the author), as well as additional requirements. Students have the opportunity to upload a file with instructions from the professor, drafts, and any other materials that the reader may find useful.

Make sure that you provide all the information as fully as possible because it is necessary for the author to understand your expectations. If you have a list of ideas on your paper, add them because both parties are interested in an amazing final result.

I find the FreeEssayWriters ordering process very simple and convenient. Of course, 10 out of 10.

Prices & Payment options

Many students consider prices to be one of the most important criteria for choosing a writing company. When your budget is tight, you cannot afford to hire any author. At the same time, you certainly want the quality of the paper to be high enough.

What can I say about the pricing of this company? First, you won’t find a page with FreeEssayWriters prices on their website because they offer a unique solution for each client. Information that one page of an essay costs 10 dollars or more will not help you in any way if you have a specific assignment.

Therefore, you can find out the price by starting to place an order. Indicate the main details that I described in the previous paragraph and indicate the number of pages, deadline, and author level. A two-page university essay with a 14-day deadline will cost $ 38.4. This is a reasonably affordable price.

The FreeEssayWriters accepts credit cards, so you can pay for your order with fewer hurdles wherever you’re currently located.

My rate is 10 out of 10.

Discounts & Special offers

The discount is the factor that helps companies increase their customers’ loyalty. Even if you are ok with the final price, it is always nice to get something for free or to receive a discount.

I have already mentioned that FreeEssayWriters have several free services. They offer discounts as well, so you need to subscribe to their newsletters and wait for the good news. Don’t miss the opportunity to reduce the final price and get the most out of the writing service.

My score is 10 out of 10.

Quality of the website’s content

I have studied the content that this company offers and can write about it in more detail.

Firstly, they have free essay topics, and this section is just amazing! You know the situation when you’re just sitting and can’t come up even with a single idea. Now you shouldn’t worry about it since they have developed a lot of ideas for you, regardless of the level. For example, you can find Internet essay topics, sociology essay writing guide, top 10 topics for argumentative papers, and so on. Very inspirational! You may use these topics or read them to come up with your own.

Next, their sections with free samples and templates are also very useful. If you need to understand what the reference essay looks like, you can find the answers right here. Besides, it is the perfect opportunity to understand the level of their authors since these papers were written by them.

And finally, there is the FreeEssayWriters’s blog with various articles on different student-related topics. Best experts share their tips to follow, discuss important issues, provide you with new ideas and support.

It goes without saying that their content is just amazing, so FreeEssayWriters rating for content is 10 out of 10.

Meeting deadlines

Ordering a paper, you should indicate your deadline. If you have enough time to go, it would be the best solution to choose 7 or 14 days. The difference in prices is very insignificant. However, many students have assignments that should be completed as soon as possible, even for about 3 hours.

Just imagine that you should deliver your paper in 4 hours, and the professor won’t wait even a minute more. Of course, you expect that the professional writing company will deliver it on time. Any delays are impossible. It doesn’t matter how good the paper is if you can’t send it and get a good grade. Timely delivery is a very important criterion, and many companies are not good at it.

The good news is that the FreeeEssayWriters company works without any delays. I have received my paper even earlier than I expected. And I have also read a lot of reviews, where students say they are satisfied. As I mentioned at the beginning of this article, they say they deliver 99% orders on time. Force-majors are possible, but 1% is an acceptable level.

My score for this criterion is 10 out of 10.

Customer support service

Modern students are fortunate ones since they can hire a tutor or a writer online, just from their smartphones. It doesn’t even matter where you are located since most writing companies work 24\7.

The FreeEssayWriters is not an exception. They are always available, and they ready to provide you with friendly customer support. If you have some questions that are not answered in the FAQ section, you can send them an email or contact the manager via phone. You can always expect help and qualified assistance.

I can’t say how do they behave in conflict situations because it looks like they don’t have any conflict situations. But I’m sure that the FreeEssayWriters’ team is absolutely customer-oriented and is always here to have your back.

The score is 10 out of 10.

Extra opportunities

Firstly, you can check your paper for plagiarism absolutely for free. Any paper, even if you’ve written it yourself. And if you want to have an official report, you can order it along with the assignment.

There are also other additional services, such as Abstract page ($14.99) and High Priority ($14.99). They are not necessary, but they can save you a lot of time. Don’t forget about free opportunities; use topics, samples, templates, blog articles if you need to come up with a decent paper. As you can see, this company is a reliable friend who is always ready to help you. They don’t want you to order all assignments, just define your priorities and let professionals support you when you really need it.

10 out of 10.

Reputation & Guarantees

Online reputation is very important these days. You need to keep this in mind when you want to leave a bad review simply because you are in a bad mood. Reading reviews, you should also understand that people have different expectations. But it is not about FreeEssayWriters; they have a fantastic reputation. Take a look at some phrases from independent platforms: “Reliable and perfect for long dissertations”, “Indeed this service is top of the line and I’m satisfied with their excellent service.”, “Brilliant Writing Skills”. If you make the order, don’t forget to leave your FreeEssayWriters review to help other students get the bigger picture.

And what about guarantees? They are necessary to understand that you’re on the same wavelength as the company is. It gives promises, and it should keep it. FreeEssayWriters guarantees customers:

  • Professional essay authors;
  • 24\7 customer support;
  • Paper help with on-time delivery;
  • Unlimited free revisions;
  • Money refund.

You can find additional information on the FreeEssayWriters to make sure you understand the Terms.

10 out of 10 for reputation and guarantees.

Final verdict

Finally, I can say that FreeEsssayWriters.net is one of the best writing services to choose from. My verdict is 10 out of 10. Sounds impressive, right? Of course, each student has expectations and requirements, but I have no doubt that this company can meet them.

If you understand that you don’t have enough time, feel bad, have other important tasks, or just want to save a couple of hours and get the best grade, don’t hesitate to use professional assistance. Such companies as FreeEssayWriters work to make you happy!
