Ancient Planet Hides Inside Earth for 4 Billion Years

you take off from earth and park your spacecraft somewhere near the moon you're now almost 240 000 miles away from your home planet that's almost 100 widths of the united states now you take out a giant hammer and an enormous chisel using the robotic arms of your spaceship you place the chisel at the earth's north pole and strike its head with the hammer earth splits open like an eggshell and you see it another planet it's thea and it's hiding inside our planet like a yolk in an egg you'd need to go back in time 4.5 billion years to find out how it got there this beautiful nebula will soon become our solar system colored dust and various space debris are slowly coming closer toward the common center soon this jigsaw puzzle of debris becomes too heavy and dense the temperature inside the giant is rising soon it gets so high that it triggers a nuclear chain reaction another second and bam there's an explosion so powerful that the shock waves travel far into dark space and the blinding flash from this blast can be seen from the other side of the milky way galaxy when the dust clears a little you can see that a bright light is still shining at the very center of the explosion this newborn star is the sun it weighs as much as 333 thousand earths if the sun was a bucket you'd need 1.3 million earth-sized planets to fill it you're interested in a small object over there 93 million miles away from the sun this pile of rocks and hot lava is earth right now the planet is busy forming its core while the oceans of lava are gradually cooling down but a few tens of million years after the sun's birth you notice a strange object hurtling toward earth it's thea this small planet was born at about the same time as earth and now it's following a crazy spiral trajectory at enormous speed scientists believe thea was kind of a ball jupiter and venus played with venus was pulling thea in one direction then big brother jupiter pulled it back but the sun makes up 99.8 percent of the mass of the entire solar system that's why the star sets its own rules it makes the move in almost the same orbit as earth so they inevitably come closer and closer to each other until they become next-door neighbors we see that thea is the size of mars and as wide as the atlantic ocean from new york to portugal [Music] a collision can't be avoided thea is traveling toward earth at nearly 9 000 miles per hour that's 11 times faster than the speed of sound if the smaller planet crashes into earth at a particular angle earth will most likely be torn apart as well as thea itself the collision will cause a huge blast visible on other planets even on a bright day nothing will be left but some burning dust and debris even if thea touches earth only lightly it'll still knock out a chunk of our planet the size of australia but the collision with thea happens at a perfect 45 degree angle it strikes the earth at tremendous speed the explosion literally vaporizes huge amounts of rock and the shock wave sends the remaining debris into earth's orbit a huge crater is formed at the impact site soon it gets filled with boiling lava the remnants of thea and the ejected fragments of earth begin to orbit our planet according to one version these fragments form two moons at first they travel together but one day they get too close to each other and collide forming one large space body the other theory claims that all the shards start being pulled by the remnants of thea some time later they form the moon as we now know it at that point in the past though it's just red hot rock and lava the collision at this angle slightly tilts our planet and accelerates its rotation it's because of thea that we have different seasons and 24 hours in a day earth has lithospheric plates these are enormous solid pieces that make up the crust of our planet after the collision with thea they start to break and crack it causes carbon a primary component of all known life on earth to start moving all over our planet so earth gets some kind of metabolism after a few hundred million years the first living creatures start to appear on our planet over nearly four billion years simple single-celled organisms have been evolving into the life you see today according to scientists such a collision is a very rare event the probability that somewhere out there there's a planet like ours that has survived the same catastrophe is extremely small this may be the reason why we are yet to find traces of other civilizations out there in space meanwhile the remains of thea are still here on earth of course it doesn't look like an entire planet stuck inside our own most of the fragments have melted and blended into the earth's crust if you take the top layer off our planet you'll see two huge lava blobs the size of entire continents they're right below africa and the pacific ocean presumably these are the remains of thea they didn't mix with earth's mantle because of different densities it's like mixing water and oil in a glass the oil will always float up over the water and create an even layer on top of it but if you raise those lava patches up to the surface they'd be 100 times higher than mount everest other remains of thea might be on the moon the apollo space missions brought back many soil samples for analysis scientists have concluded that the moon is very similar to earth and structure people could drill deep down and take samples there then they'd analyze the blobs from earth if their structure matched it'd be 100 proof that thea did hit earth 4.5 billion years ago and that's how we got the moon but for the time being thea remains somewhat mysterious scientists are still not sure that the planet actually existed the whole idea perfectly fits the model of the moon's creation but in fact this incredible collision may have never happened hop on the bright side of life together with our brand new tees hoodies and more click the link to pick your choice now you travel 41 light years away from earth to the planet 55 cancri e it's about twice the size of earth and 8 times heavier you take out your giant hammer again and use it to hit the chisel the planet cracks and you see it's a giant diamond the temperature on this planet is tens of times higher than that of earth and its soil is rich in carbon the heat puts a lot of pressure on this carbon its structure changes first it turns into graphite some more pressure and graphite turns into diamond on earth diamonds form at depths below 60 miles where the pressure is 50 000 times greater than on the surface the temperatures there rise over a thousand degrees which is as hot as fire diamonds are ejected closer to the surface in volcanic eruptions still people have to dig mines 1500 feet deep to find these beautiful gems the golden jubilee diamond is the biggest cut and faceted diamond on earth it weighs as much as a chocolate bar and is the size of a hamster its price is about 12 million dollars now imagine a diamond the size of an entire planet you decide to fly back to the solar system your destination is jupiter's moon europa it's as wide as the distance between seattle and houston and its mass is less than one percent the mass of earth its surface is enclosed in an icy crust it's about 19 miles thick but what if you crack this crust with your giant hammer wow europa is completely covered in water it's freezing here three times colder than at the north pole on earth the water turns into ice almost instantly but the ocean beneath the surface is still liquid europa interacts with jupiter gravitationally just like the moon with earth this creates tidal forces and heats europa's core the core melts the ice around it the result is a huge ocean two to three times larger than all of earth's oceans combined scientists believe that water is the basis of life it may mean that life may exist on europa there could be thermal springs just like at the bottom of our oceans the water there is probably much warmer and even though the pressure and temperature in such places are likely to be extreme simple bacteria may live there europa is almost the same age as earth this means there has been enough time for living organisms to appear and evolve who knows maybe some advanced civilization is already blooming under this crust of ice they may be building big cities and dreaming of conquering space right now but the only thing people can do at the moment is send a probe to europa and find out if life is possible there
