Can We Build a Planet From SCRATCH?

Whether is human activity were a giant

meteor crashing into us planet Earth is

not gonna last forever eventually the

lump of space rock that we call home

will one day no longer exist so what

will we do as a species if this were to

happen the obvious plan is to reach out

into the universe and build colonies

elsewhere but space travel is incredibly

complex and we're still not sure if it's

even possible to reach another solar

system within a reasonable amount of

time

but what if we built an entirely new

planet ourselves we see artificial

planet sized objects quite often in

science fiction from the Death Star of

Star Wars the planets building facility

and Hitchhiker's Guide to the galaxy and

even far larger objects like a Dyson

Sphere

the species shown being capable of

building such creations are of course

incredibly advanced but what exactly

would it take to actually build one it

first depends on what you mean by the

question are you talking about a replica

of a planet like Earth war a space

station that's the size of a small moon

or planet the former would require a

careful combination of elements and mass

Wow the latter would still require

enormous engineering feeds but maybe not

quite as difficult the most famous

planet sized Space Station from sci-fi

is of course the Death Star according to

estimates at the construction of such a

structure which is 74 miles in diameter

compared to the Earth's 8,000 miles

would require materials that weigh

approximately one quadrillion tons which

is about a millionth of the weight of

Earth supplying all the material would

be a mammoth task and impossible with

current technologies for example on

earth we produce about 1.5 billion tons

of steel a year which means it will take

more than 800,000 years to produce

enough for a moon sized space station

furthermore it would cost about 852

quadrillion dollars and that's not even

taking into account how will transport

them into space but let's say we could

do all that once it's there the

construction would actually be

relatively easy we can use robots to

complete most of the work in the Lac

gravity is faise means it wouldn't be

too difficult to move all the materials

into place it would take a long time but

eventually that would be possible now

the alternative will be to mine all the

materials from asteroids that are in

space already a number of companies are

actually looking at the feasibility of

doing this with some tests already being

underway if successful it could vastly

reduce the cost of building things in

outer space this may also be a better

plan because it's not even certain that

steel would be strong enough we may need

to create artificial gravity which can

be done by spinning the station and the

force this would exert could crumple

steel so some researchers think a

carbon-based material Arvest it from

asteroids would be much better suited to

the job now despite the difficulties

with building a mu sized structure

creating an actual planet is a much much

bigger problem after all the earth is

already 4.5 billion years in the making

so how could we possibly replicate that

well we wouldn't actually have to

perfectly replicate the earth to get

similar conditions for example gravity

is related to mass so we could put the

equivalent of one tenth of the Earth's

mass of rock into a shape the size of

our moon to get the same result there's

so much rock and debris in space and our

planet itself is formed by enough of it

collecting together so if we could

develop technology that did this for us

we'd be off to a really good start

following this some have suggested we

could build a fusion facility near the

Sun which could produce some of the

heavier elements that are needed these

dense metals could be layered on top of

each other allowed to cool and then they

would form a stable structure the

problem with this is that it would take

tens of thousands of years to complete

while building a planet completely from

scratch is far beyond our capabilities

the idea of terraforming and already

formed a planet is far more within the

realms of possibility nuclear

detonations could be used on Mars to

warm the planet's atmosphere and nASA

has suggested that an artificial

magnetic field could be created to

deflect solar winds in the same way that

a natural formed one would it's thought

that this type of structure would allow

Mars's atmosphere to thicken which would

warm at about 7 degrees

Fahrenheit and in turn melt the polar

ice which could contribute to a

greenhouse effect and warm the planet

further according to researchers this

could be possible within a few decades

far sooner than creating an entire

planet from scratch in conclusion the

idea of building a brand new planet

sounds pretty exciting but it is way

beyond our current technologies if we

perfected the mining of asteroids and

critter robots that won't eventually

turn on us then it could be possible to

build a large space station although

this would be a monumental project to

undertake so basically is far more

realistic to look to our neighboring

planets and to work out a way to adapt

their environment to make them less

hostile and this is gonna be the most

likely way that we'll be able to find

somewhere other than earth to live thank

you guys so much for watching and let us

know in the comments below do you think

it's ever gonna be possible for humans

to build an artificial planet and should

we make sure to give us a like if you

enjoy this video and we'll see you next
