How About a New Theory of Earth Formation ?

How About a New Theory of Earth Formation ?

so we don't have all the details about

how the universe our solar system and

its planets came to be but one thing's

for sure Earth didn't just pop out of

thin air.

scientists have recently made

an intriguing discovery that suggests

our planet may have formed way faster

than we previously thought.

you see up until now experts believe it

took over a hundred million years for

Earth to take shape the common belief

was that lucky collisions with

water-rich asteroids brought water to

our planet.

a recent study however

proposes A Whole New Perspective

according to these researchers there's

evidence that Earth formed through the

rapid accumulation of tiny Pebbles each

roughly the size of your fingernail in

this scenario our awesome Planet emerged

in only a few million years and here's

the mind-blowing part they suggest that

water being here isn't just some happy

accident but a natural result of the

formation process

now this discovery has implications that

go beyond Earth itself if our planet

formed quickly and water was an integral

part of the process it means the chances

of finding habitable planets in other

solar systems are way higher than we

ever imagined if we stumble upon other

planetary systems with planets orbiting

sun-like Stars at the right distance

there's a good chance we'll find water

there too that's a nice Intergalactic

real estate that we might just be able

to relocate to should we ever get in

trouble here on Earth

the old school view was that planet

slowly took shape through countless

collisions over millions of years

according to that theory water on Earth

would have been a random Stroke of Luck

may be caused by comets packed with

water crashing into the planet during

its later stages of formation

the new study introduces an alternative

Theory too picture this a young son

surrounded by a disc where the planets

are popping up this disc is filled with

tiny dust particles now here's where it

gets exciting once a planet reaches a

certain size it acts like a cosmic

vacuum cleaner swiftly hoovering up all

the dust in his path in just a few

million years this tiny planet grows

into the size of Earth

this not only shapes our incredible

Planet but guarantees water's existence

too as the planet gobbles up the dust it

also snags icy particles floating around

in the disc so if we use Earth as an

example it suggests that whenever a

similar Planet forms it's bound to have

water naturally

there's no way for us to travel back in

time and see for ourselves so there are

more theories about how planets are born

into a different scenario called The

Core accretion Theory picture a big

cloud of dust twirling around in space

as where the action begins over time

this Cloud starts pulling in an

astounding 99.8 percent of all the

matter eventually creating our sun right

at the center of our solar system

soon enough solar winds join the party

bringing in lighter atoms like hydrogen

and helium that are closer to the Sun

but those heavier elements the sun can't

pull them in because well they're too

heavy so what do they do they gather

together and stick to each other forming

their own little planets that's how

Earth Mars Venus and the Gang got

together to create round spheres the

heavyweights like zinc and iron sank to

the middle forming the core while the

lighter elements meshed on top creating

the crust but wait we can't forget about

Jupiter its gravitational force and the

suns were locked in an epic tug of war

perfectly balancing each other out

that's why we have that fascinating

asteroid belt hanging out between Mars

and Jupiter those poor asteroids never

got the chance to become fully fledged

planets on their own

this explains why the planets in our

solar system are arranged the way they

are the inner ones known as the

terrestrial planets like Mercury Venus

Earth and Mars are closest to the Sun

they're made of denser stuff like iron

silicon and aluminum on the flip side

the gaseous giants like Jupiter Saturn

Uranus and Neptune are chilling on the

outer edges of the solar system these

big celestial bodies are composed of

lighter materials such as hydrogen

helium and methane now let's take a trip

to the outermost layer of our solar

system where the Kuiper belt and the

Oort cloud reside these distant areas

are home to ice bodies space debris and

comets while there may be plenty of them

they're relatively small and don't

contribute much to the total volume of

our solar system

the quest to understand Planet formation

doesn't end here there's another

mind-boggling mystery that's causing a

stir among scientists the existence of a

Celestial body dubbed the planet that

shouldn't exist let's rewind a bit

astronomers have been on a roll with

exoplanet discoveries and we've already

spotted over 4 000 of them most of these

exoplanets resemble the gas giants in

our own solar system like Jupiter and

Saturn do you know why it's because

those massive exoplanets close to their

stars are the easiest to detect but

here's the twist a new study suggests

that there's a whole bunch of

jupiter-like exoplanets just waiting to

be found and they're probably hanging

out nearby

by The Impossible name

jg3512b and it's remarkably similar to

Jupiter only orbiting a tiny red dwarf

star

Discovery shook things up because it

defied the most popular theory of Planet

formation according to the prevailing

ideas it should have been impossible for

such a giant planet to form around such

a small star

so what's the deal with this impossible

exoplanet well it turns out that core

accretion the theory we discussed

earlier can't explain its existence

according to this Theory the mass of the

debris disc surrounding a young star

should be directly proportional to the

star's Mass but here we have a star much

smaller than our sun hosting a planet

that should be way too massive for it

something doesn't add up either the

original debris disc was insanely

enormous compared to the star or core

accretion didn't play out as expected in

this particular planetary system

we've established that when talking

about the Earth formation there's still

much we don't know but hey we've come a

long way back in the 18th century a

philosopher named Emmanuel Kant had his

own intriguing theory about planets

popping up in the universe he based his

ideas on Newton's law of gravity but

added his own little twist Kant believe

that the Universe started with an

original substance made up of super cold

solid particles just chilling out then

thanks to gravity these particles began

colliding and heating up and you know

what happens when things Collide right

they get hot according to Kant this

Cosmic twirling and heating up caused

some serious forces to come into play

it's like when you spin around so fast

that you feel like you're about to take

off these forces led to the formation of

rings of matter like Cosmic hula hoops

and as these Rings cooled down they

transformed into planets and satellites

now not everyone was convinced by Khan's

wild idea of Planet formation critics

raised their eyebrows and started

questioning the whole Theory they

pointed out that Kant failed to address

the origin of this primordial matter

where did it come from in the first

place moreover he overlooked the source

of energy that propelled these particles

from a state of cold Stillness to a

frenzy Cosmic dance-off as creative as

his theory was it soon faced dismissal

in the scientific community in short

they said this can't happen

nevertheless conch theory was still a

step forward compared to older beliefs

about Earth's origin take the ancient

Egyptians for example they believe that

primordial Spirits often depicted with

frog heads in their native artwork were

responsible for our planet's existence

why frogs you ask well they Associated

the first substance in the universe with

water and frogs just love humid

environments so out of that initial

water a primordial Hill emerged followed

by the elements of air and moisture

ribbit.
