What If We Lower the Solar in a Half?

published on July 2, 2020

imagine it's early morning you're

stretching making coffee in the kitchen

while frying eggs you turn on the TV out

of boredom a running line appears on the

screen you bolt to the window lift the

blinds with one hand and hold your

breath for a second – so far so good

the room is illuminated by a bright

light but for how long could the planet

survive if a piece or even half of the

Sun got sliced off get ready

today a fantastic experiment awaits you

to get started let's fast forward to the

Sun to understand the situation we need

to consider how everything works inside

of our star the Sun is a huge flaming

ball of gas and plasma made up of

several different layers of course the

world hasn't yet invented a material

from which we could forge the most

heat-resistant space knife after all the

average temperature of the sun's

atmosphere reaches two million degrees

Celsius that's 36 million Fahrenheit

and inside its core it's seven times

hotter even the most fireproof material

to date which is an alloy of tantalum

hafnium carbide would melt at three

thousand nine hundred and ninety degrees

Celsius that's seven thousand two

hundred and fourteen Fahrenheit but

let's imagine there's a giant space

knife made of the latest material able

to withstand any temperature and density

of matter it would be delivered to the

Sun by an autopilot spaceship because

it's too hot for a human to travel there

and let's all agree right away

then we all understand perfectly well

that in reality it would be impossible

to cut off a part of the Sun as I said

earlier the surface of the Sun is not a

solid substance but a turbulent boiling

plasma but we have an experiment here

right therefore the Sun in our video

will be cut into pieces like a

watermelon if the inside of the Sun were

empty we'd need about a million planets

like ours to fill it but inside our star

there's already a filling a mixture of

hydrogen helium and literally a pinch of

other elements however while we've been

chatting a huge space knife has already

cut off the top of our star now there's

no reason to panic only the outer layer

of our luminary was disturbed the

chromosphere of course the Sun still has

a hellishly hot Corona and a transition

region but there's nothing that could be

cut there the density of this matter is

so low that it's almost comparable to a

vacuum so let's get right into it given

the size of the Sun the piece we sliced

off is just over two thousand kilometers

or about 1,200 miles thick and its

surface area is 9 billion square

kilometres that's about three and a half

billion square miles which is difficult

to imagine the surface of the

chromosphere can't be called smooth it's

all dotted with luminous columns of

plasma like spikes if you simply cut the

Sun and moved a piece of it into space

our star would instantly pull it back

the gravity of the Sun is so strong but

it would do so with ease as it would be

with any part of the star which is

extremely important to maintaining the

shape of the sphere but let's imagine

that this piece simply disappeared into

space what would happen

most likely nothing fatal the mass of

the Sun would still be large enough to

continue fulfilling its function the

main variable here would be if this

cutoff piece of the Sun moved towards

the Earth

when approaching our planet it could be

destroyed by the pressure of the Earth's

atmosphere and a vacuum would form in

its place

an explosion would occur and a shock

wave would cover the planet it would

break windows and tear apart our

eardrums in general not great prospects

now let's make an effort and cut off

exactly 1/4 of the Sun here all layers

of our star would be affected our knife

would go through the chromosphere hook

on the layer below the photosphere then

additional layers and of course reach

the solid core Thanos

snaps his fingers and a quarter of the

Sun disappears in space imagine that in

the most dangerous vessel in the

universe where the pressure is 265

billion bar there's now a hole and now a

huge amount of hydrogen and helium

heated to gigantic temperatures together

with gamma radiation bursts from its

bowels there are no more layers

restraining absorbing and distributing

this mad energy how would this threaten

the earth unprecedented gamma radiation

this has a very high penetrating ability

but while passing through the Earth's

atmosphere it would partially dissipate

in the event that the solar core was

exposed the strongest gamma-ray burst a

large-scale cosmic emission of explosive

energy and incredible brightness would

fall upon our planet our atmosphere

could still withstand the pulse wave by

arrays would begin breaking the bonds

between nitrogen and oxygen molecules in

the atmosphere as a result we be

awaiting supercooling abnormal rains

from nitric acid and solar radiation in

fact the Sun we now know would cease to

exist this would be the birth of a new

star and at the stage of birth a star's

character can be quite unpredictable

it's unlikely that the usual order of

the solar system would be preserved

after all the Sun is 998% of the total

mass of the entire solar system and

suddenly this number would decrease by

1/4 most likely the earth would no

longer be able to rotate as before

around the Sun the brightness of our

star would drop 25% so the earth would

no longer be in the habitable zone of

the Sun it would begin cooling until all

rivers and oceans froze within a few

years the Earth's surface would turn

into an icy desert like on Europa

Jupiter's moon if humanity could survive

it would only be in some underground

bunkers the simplest forms of life would

be preserved only in hydrothermal waters

and in any case if a small piece of the

solar course somehow reached earth then

there would be no trace of an ice crust

left just imagine in order to destroy

all life within a radius of several tens

of kilometers a substance literally the

size of a pinhead would be enough so

what do you think would happen if a

quarter of the entire solar core reached

the earth as you might have guessed when

the Sun loses half of its mass the

changes would have an even more

deadly effect it's unlikely that

humanity would have months to adapt to

new conditions if we weren't immediately

killed by the strongest gamma-ray burst

then natural disasters a magnitude of

which Earth has never encountered before

would do so but if somehow lucky

survivors remained on the planet then

they would inevitably die shortly after

anyway earth would be thrown out of the

solar system through the vast expanses

of space without a protective Sun it

would become a target for asteroids

meteorites and other planets it's hard

to imagine such a multi-layered killer

scenario even in the most exciting

blockbusters perhaps the Sun is best

left alone however if you think the idea

of controlling stellar matter is

something only my imagination could come

up with then I must upset you scientists

have long been looking at stars with the

goal of stellar farming it'll be

important for future generations

and perhaps even our direct descendants

to control the evolution and properties

of a star including increasing its

lifespan extracting materials or even

creating new stars but not for the sake

of mere curiosity for example in order

to increase the lifetime of a star it's

necessary to slow down the nuclear

fusion taking place in its core so you

would need to rid it of excess mass

stars already lose a small flow of mass

via solar wind coronal mass ejections

and other processes a method called star

lifting would have to increase the

natural plasma flow so that it could

then be manipulated using magnetic

fields the idea is excellent but it's

scary to imagine what the consequences

might be if we try intervening in the

ways of the universe to minimize risk

we'll need something to hone our skills

on for example in

artificial sun such a simulator is

already operating in the United States

and one will soon appear in China this

son can be fearless leap loan up cut

reduced and enlarged and only after we

know in advance all the possible

consequences and understand the risks

would we move to the next level working

with a real object in the meantime let's

let everything be and let these

experiments merely remain as figment of

our imagination so what do you think

about manipulating stellar matter let us

know in the comments and don't forget to

we still have a lot of ideas and

experiments ahead
