A new, clearer insight into Earth's hidden crystals

Geologists have developed a new theory about the state of Earth billions of years ago after examining the very old rocks formed in the Earth's mantle below the continents.

“The seven continents on Earth today are each built around a stable interior called a craton, and geologists believe that craton stabilisation some 2.5—3 billion years ago was critical to the emergence of land masses on Earth.

Little is known about how cratons and their supporting mantle keels formed, but important clues can be found in peridotite xenoliths, which are samples of mantle that are brought to the Earth’s surface by erupting volcanoes.”

“The research used a new thermodynamic model to calculate that the unusual mineralogy developed when very hot molten rock— greater than 1700 °C—interacted with older parts of the mantle and this caused the growth of silica-rich minerals.

“For more than 1 billion years, from 3.8 to 2.5 billion years ago, volcanoes also erupted very unusual lavas of very low viscosity—lava that was very thin, very hot and often contained variable levels of silica,“”

I love your blog and your space asks but please pray tell what's the moon boom that jumpingjacktrash mentioned?

have you ever looked up into the night sky and wondered, why the moon is?

well, you’re not alone! scientists and learnéd scholars across the ages have been baffled by our celestial neighbor.

WHY, is our Moon so proportionally fucking huge? (it’s more than a quarter the size of the Earth! that’s COMPLETELY FUCKING INSANE AND BLOWS EVERY OTHER MOON IN OUR SOLAR SYSTEM OUT OF THE METAPHORICAL WATER)

WHY, is the Moon made up of much of the same materials as the Earth?

and WHY, is Earth’s magnetic field so massively overpowered that it can shield the surface from interstellar and solar radiation, allowing life to develop and paving the way for you to even ask these questions in the first place? (that one might not sound related, but I promise you it is so just bear with me)

well, it all comes down to the Theia Impact Hypothesis, or, OPERATION MOON BOOM.

in this fair solar system we lay our scene, four and a half billion years ago.

here, we focus on the third planet from the Sun, which is, surprisingly, NOT Earth.

not yet.

no, this unnamed rocky world is slightly smaller than Venus, and is formed of mostly-molten rock that’s still settling into itself as our nascent solar system sorts itself out.

ENTER STAGE LEFT, THEIA.

Theia is a rocky planetoid about the size of Mars, on a wild and unstable orbit around the Sun that regularly brings it within spitting distance of our unnamed third rock! and today, it will get A Bit Too Close.

the two planets slam into each other with wild disregard for road safety, disintegrating their outer layers into a massive debris field that will take hundreds of millions of years to settle and fusing their planetary cores together into a single rough oblong of molten iron! BAM! WHAPPO!

but settle the debris does, as gravity takes a gentle but firm hold of this huge mess and gradually reshapes it into two familiar faces…

ENTER STAGE RIGHT: EARTH AND MOON.

that’s right, you’re standing on top of the alchemically-fused corpses of, not one, but TWO planets right now! our newly-reborn Earth and its singular orbiting satellite are formed from the same debris field and share a lot of similar material. and because the Moon was Made, and not a domesticated planetoid that wandered too close and got trapped in the orbit of a larger body, it’s just ludicrously HUGE compared to its partner.

and getting back to that magnetic field thing, the whole reason Earth Can Have Big Field Pls is because Theia dumped so much extra iron into the Core that it generates a MUCH more powerful field than our neighboring planets, even the ones that are just slightly smaller than Earth!

the only reason that life can exist at all is because Theia took one for the team and reshaped the solar system.

so the next time you look up into the celestial dome and spot our closest neighbor, raise a salute to Theia, gone but not forgotten.

REPORT, STAT!!!

Things I need to know from the Japanese localization:

Is there anything else that’s cute or fun that I need to know?

This amazing Bangladeshi air cooler is made from plastic bottles and uses no electricity

An inventor in Bangladesh created a DIY air cooler with discarded plastic bottles, and he's giving the plans away for free, just in time for summer.

This you can even make with a cereal box, pop bottles, a craft or box cutter knife, and some duct tape.  For those who are trying to beat the heat and don’t have an AC unit, or are trying to save money on their electricity bill.

To make your own, please follow the following steps for a window strip:

Materials:  Cardboard (i used a cereal box), Duct tape (in the colour of your choice), pop bottles or water bottles (just the tops as you can see how they were cut), some cutting device to cut cardboard and/or tape, and a marker, or marking device of your choice that will mark onto cardboard 

Step 1)  Cut off your pop or water off at the widest point so it makes kind of a funnel shape

Step 2) you can make these bigger, but I made mine into a strip.  Cut the cardboard into how big you want your panel or strip.  Trace the base of your cap and mark the centre of where the lid goes with an X (thats where the opening will go.  In the picture, I made mine just a bit wider than the pop bottle tops

Step 3)  Cut the X where you marked it, and make it so it’s cut big enough to push the smallest part of your bottle through the X

Step 4) Secure all the spout parts with Duct tape (in the colour of your choice.  Mine’s purple.)  You do not have to do step 4, but it is advised so the pop bottle tops dont pop out of the openings you made.

Step 5) Place your strip or panel with the biggest part facing the screen or opening of your window, and have the smallest part facing the inside of the building.

The science:  as the air blows into the wider part of the pop bottle cone, it compresses the air and cools it down as it goes through the smaller part, hence cooling the air around you without having to use any electricity to make this work.

I hope this tutorial helps you to beat the heat!
