The Secret of the Dark Side of the Moon

four billion years ago asteroids rained

down on the newly formed moon tearing

into the surface where the fractured

crust is thinnest molten lava seeps from

the moon's hot interior spreads out and

giant pools and solidifies to form the

scars we see today from Earth

and strangely

although the moon rotates the Earth's

gravity holds on to it so tightly the

same face points towards us at all times

making the features on the far side of

the moon a complete mystery for all of

history the far side of the Moon was

invisible to the earth it's the back

side you can't see it

in 1959 Soviet spacecraft Luna 3 flies

past the moon's far side and photographs

it for the first time astronomers expect

to see the familiar dark and light

patches they were in for a big surprise

when scientists saw the pictures they

were shocked the far side looked

completely different than the near side

it's saturated with craters it just was

such a huge dichotomy nobody was

expecting that at all

the far side still had massive impact


but it was uniformly pale it seemed like

no dark lava had bled out onto the

surface at all but why the only solution

we could come up with is there's a

difference in thickness between the

crust of the nearside and the crust of

the farside the backside must be so

thick that lavas are not able to come up

through them and erupt out onto the

surface instead on the front side where

it's very thin lavas can easily come up

through cracks and flow out onto the

surface recent NASA missions confirm the

crust on the back of the Moon is around

30 miles thicker than the crust on the

front the far side is thicker it's not

like Oh

part of it is and part of it isn't no

it's really the other side of the Moon

has a thicker crust than the near side

that's bizarre so one of the biggest

mysteries in planetary science over the

last about 50 years is you know why is

the crust to the far side so thick the

impact Theory doesn't really cover that

it just forms the moon but it doesn't

say why one side should be so different

than the other one unless something

strange happened

the New Age of supercomputers brings

about the first credible explanation the

impact of theá-- could have made two

moves not one

at this double birth white also

explained our double-sided Lu

according to the theory 4.5 billion

years ago there are two moons in the

night sky the smaller moon chases its

larger sibling gradually getting closer

eventually the two moons mushed together

in slow motion and the smaller moon

covers the far side of the larger moon

creating a new much thicker crust not

all impacts are high speed super violent

events that eject material everywhere

instead of just wham smacking into it it

would have just merged with it just been

pulled apart and smeared out over the

moon essentially when you look at one

half of the moon you see more of one

body and we look at the other side of

the Moon you see more of the other body

they kind of wrapped around the first

body and so it's thicker on that side
