Have you ever wondered what it would be like to walk on the moon? Or on Mars? Sure, you can go to NASA and simulate it as closely as possible, but nothing beats the real thing! So why not create artificial gravity right in your own home? There are many online resources that show you how to create artificial gravity using centrifugal force, but most of them use equipment that’s difficult to acquire or assemble—or both! This guide to creating artificial gravity will show you how to do it at home with just an old washing machine and some magnets.
Introducing artificial gravity
One of the biggest drawbacks to living on a space station is
that it’s impossible for humans to stand upright. For one thing, Earth’s
gravity keeps us grounded, but also because our sense of balance relies on our
spines being compressed against gravity—and in space, you float around like an
unbalanced potato. In fact, if you put your feet under your butt and try to
stand up straight in a chair or bed on Earth, you’ll immediately feel wobbly.
This floating effect is similar (albeit less intense) during microgravity
aboard spacecraft as well as astronauts' experience in zero-G conditions during
space flight. And while space agencies have been working on ways to combat
these negative effects by designing special exercise equipment, clothing, and
even shoes that help people maintain their posture in space—there are no real
solutions yet. But there is hope: A team of researchers from MIT recently
discovered how to create artificial gravity using a rotating frame. And they
did it by studying...fruit flies? We know what you're thinking: fruit flies
don't live long enough for artificial gravity research! But it turns out fruit
flies are really good at showing signs of aging quickly. So what does all of
this mean? It means we could soon have a way to create artificial gravity
without having to spend billions building new space stations or sending more
people into orbit.
Two gravitational systems (closed vs.
open loop)
There are two methods for creating artificial gravity, one
called a closed system and one called an open loop. Let’s start with a
description of each: Closed system: A closed system refers to how gravity is
generated in relation to where you live on Earth. Essentially, it’s created by your
planet’s gravitational pull; once you have reached a height of 10,000 feet or
more from sea level, there is no discernible gravity on your body. That’s why
astronauts can float around in space without any issues—they are simply not
being pulled down towards their planet. Open loop: An open-loop system refers
to an artificial-gravity generator that creates its own gravitational field—no
matter what altitude you find yourself at. This means that astronauts could be
floating around inside a spaceship traveling through space, but they would
still feel as if they were standing on solid ground. It also means that if
someone were to fall over while wearing a spacesuit made for an open-loop
environment, they would hit their head on something hard—even though nothing
exists around them but empty space!
Starting simple (beginner)
Our first step is going to be simple. We’re going to find a
partner who is willing help us with creating artificial gravity. From there, we
are going set up several systems that are designed around generating
micro-gravity through centripetal force. At least, that’s our plan and only
time will tell if it works. If you want more detail or want a specific set of
instructions, you can either reach out directly or wait for an updated version of
this guide in about a month (the intent is for these updates to happen on a
weekly basis). Either way, I hope you enjoy! And remember: don’t try anything
stupid! This stuff isn’t cheap and no one wants to see your blood splattered
all over their walls. That said, let’s get started!
The first thing we need to do is figure out how fast we want
our space station to rotate. A quick online search shows many DIY projects
suggesting 2 rotations per minute as a good pace. But there are two problems
with doing so. The main problem, which I hinted at earlier, is that many of
those same sites end up in court due to potential injury and/or property damage
– it gets expensive real fast if something goes wrong!
Intermediate Level (intermediate
level)
If you have ever been on a plane, you have experienced
artificial gravity: while flying, objects and people experience reduced weight.
This effect is created by applying force to something in a way that allows it
to move in relation to itself or another object. Airplanes are able to create
artificial gravity for their passengers because of thrust. In order for an
airplane's engines to generate enough force for flight, they must be powerful
enough. That power is transferred from engines through propellers and then
forces travelers back into their seats with equal force as if they were being
pulled down by gravity's pull towards Earth's center. (Source) If only airplane
seats had strong enough back support for our homes! Wait... we can make that
happen!
Advanced Level
(advanced level)
Inventing a new means of creating artificial gravity within
your home is not for beginners. To replicate human-level gravity, you’ll need
more than just a spinning chair or an upside-down mattress—you’ll need a
fundamentally new system. That said, if you have some understanding of physics
and mechanical engineering concepts, it might be possible to invent your own
solution. Here are three ways to create artificial gravity that might be doable
by people with moderate knowledge in these areas
Life Support Systems (life support
systems)
You’ll also need some sort of life support system, as Earth
has gravity and space does not. For example, you could plant a large number of
trees in your backyard—then tie strings between them that go up to your ceiling
fan. Spin it really fast and stand under it! Sure, there may be some risks
involved (if you trip over one of those lines, for example), but since
nothing’s more important than getting off-planet as soon as possible then we
can probably let them slide. If you don’t have trees or a ceiling fan handy,
though, then simply substitute some cinder blocks or a giant rock with a string
tied around it.
