What If Humans Built A Planet?
Humanity’s search for earth-like other worlds seems to know no bounds.
We’re now able to photograph the farthest places in our own solar system, but also to
locate other, far more distant planets with the potential to support life… all in the
apparent hope that one day we could live somewhere else in the universe.
But might there yet be another answer to our seeming need for a second home?
This is Unveiled and today we’re answering the extraordinary question; What if humans
built a brand-new planet?

To build a planet, we have to know what constitutes a planet first of all.
According to the International Astronomical Union, there are three criteria that a celestial
body has to meet to be one...
It has to orbit a star; be big enough to have sufficient gravity to force it into a spherical
shape; and also be big enough to clear away any other similarly sized objects in its orbit
- with that last point being primarily what led to Pluto’s demotion to a dwarf planet,
in 2006.
So, based on these entry-level qualifications, could we ever truly create our own world?
Before we even attempted to do so, we’d first need to have mastered our own planet;
to have become a Kardashev Type I society.
At that stage we’d know everything there was to know about the way that Earth worked
- being able to predict the weather, control natural disasters, and harness every single
speck of energy available to us.
And then we could use that knowledge going forwards.
In this particular alternate reality, Earth stands as a kind of planetary blueprint; a
“completed” project to inspire something else - with that “something else” being
a new planet altogether.
Seeing as a Type I civilization on its way to Type II will have also made greater progress
in terms of exploring the rest of the solar system, we’d by then have know-how gained
on other existing planets to draw upon, as well.
And, thinking optimistically, we’re already beginning to take our first steps toward achieving
this.
Projects like the Artemis Program (a majority-NASA initiative to get us back to the moon) as
well as various plans for a crewed mission to Mars could well change our scientific and
technological perspectives forever.
Should we succeed in reaching somewhere like the Red Planet, we could be well-practiced
in how to build sustainable colonies on alien landscapes in just a few decades.
For the most part, though, our ambitions for visiting other planets amount to terraforming
them - that is, making them as Earth-like as possible.
But, were we to just go ahead and build something new from scratch, then there’d be no need
to terraform because we’d create exactly what we wanted from the outset - with the
ideal size, temperature, atmosphere and layout.
It really could be “the perfect place”… but obviously dreaming it up and actually
doing it are two totally different things!
To construct an entire world where once there was nothing, we would need a lot of help from
the sun.
Typically, planets form as bits of matter circling a star accrue over millions of years
and condense into a spherical body.
So, a star is key even then.
But, we could - theoretically - build one much faster than what’s naturally expected…
According to a mid-2000s study by aerospace engineer Mark Hempsell; were we to (in a future
time) set up a massive fusion reactor close to the sun, we could harness its hydrogen
and fuse it into far heavier elements like platinum and osmium - and use those as building
blocks for our new planet’s core.
By now we’re stretching far closer to Kardashev Type II capabilities - where we control whole
star systems - but that’s what we’d need to get started.
From there, to generate aspects like rotation and convection, we’d need to subject our
sphere of new matter to incredible levels of heat and centuries-long periods of cooling,
all while attempting to build an optimized atmosphere to both allow for life and cocoon
us from radiation.
By the time we’d somehow achieved all of that, we’d had to have surpassed even Type
II, and be well on our way toward Kardashev Type III capabilities.
But what if we wanted something before then?
Before we ascended to unheard of levels of intelligence?
We could go about building a planet in a different, much simpler way…
opting for a massive metal structure something like the iconic Death Star - only even bigger
and without custom-building it for a life of evil.
Instead, our metal world - let’s call it the Life Star - would take artificial living
to whole new levels.
Everything from sky colour to oxygen levels would be in some way mechanised, with apparently
“natural” landscapes actually built to precise specifications.
It might not seem as though a structure like this could ever qualify as a genuine planet
but, going by the AIU’s criteria, if we somehow built it big enough it would satisfy
all of the requirements.
Quite how we’d afford to make and maintain the place, though, is another question entirely!
So, maybe there’s a midway point, here; a middle ground between a crisp new planet
from nothing and a clunky metal world from something like “Star Wars”?
Arguably the best course of action would be to start with massive enough celestial bodies
already in existence - like moons or asteroids.
Though again we’d need some far future technological capabilities the like of which we don’t
currently possess, say we could extract multiple objects from the Kuiper Belt or even the Oort
Cloud… and, then, say we could smash them together, forcing them to combine, before
leaving them to develop their own shape and gravitational influence while orbiting at
their new distance away from the sun…
If we ever could (and ever had the time) do all of that then we would, again, have forged
ourselves a new planet; earning ourselves an absolute blank canvas to create a new world.
From there, we’d add life… probably taking a “Noah’s Ark” approach to import animals
and plants from Earth.
Seeing as we would have custom-built our second planet to harbour whatever living conditions
we needed, by the time it came to actually living there then the transition should be
simple.
This place would be just like Earth or could even be an enhanced version of Earth - where
the environment is always rich with whatever life needs at the time.
To take it a step even further, if we really were in a position to design whole worlds,
then could we also be set to “design” the creatures which inhabit it?
Any civilization capable of creating a planet would, after all, have a god-like influence
on what exactly happens there.
But, let’s not cosmologically run before we can walk (or even crawl).
As fantastical as the idea of birthing new planets may seem, it still is just that - a
fantasy.
Which isn’t to say that something like it might not one day be necessary…
Should Earth ever become uninhabitable for any reason, then humanity will need to relocate
to somewhere.
If the other solar system planets don’t suit, and we’re unable to develop faster-than-light
travel to take us to any of the possibly Earth-like planets we’ve identified in other star systems…
then perhaps the “Life Star” really will be needed.
If not, then a wholly artificial Earth would at least serve as the ultimate in social experiments
- granting its human creators a chance to watch and record exactly how the evolution
of life plays out on it… and to determine how closely its history matches Earth’s
own.
In terms of technological achievements, it would surely be the grandest of all.
And that’s what would happen if humans built a planet.
What do you think?
Is there anything we missed?
