ooh that looks like a black hole oh no I shouldn't be here but I'm not gonna go before I tell you about black holes come with me zoo in a black hole is formed when the core of a star collapses and the star explodes therefore we can say that a black hole is born when a star dies when a massive star reaches the end of its life its go starts running out of fuel the core is no longer able to hold the star back resulting in its collapse this gives birth to a mini black hole with gravity running blind inside it the black hole starts eating up everything that's left of the star and it all happens in milliseconds even before the stock and realize what's happening to it it explodes the explosion releases a tremendous amount of energy even more than our Sun can produce in its entire lifetime whoa isn't that crazy hmm let me tell you a secret you could turn into a black hole yep the computer you're using me or anything around you that has matter has a small child radius also called the gravitational radius which is the radius of the tiny sphere into which if a mass of an object is compressed to fit in its escape speed would be equal to the speed of light which is way too much but chances of you turning into a black hole are rare because of the tiny size of your Schwarzschild radius stuff that gets too close to a black hole gets sucked in because of the super humongous gravitational pull so nothing can escape a black hole not even light hey have you ever wondered what would happen if two black holes collided chances are that they might become one big black hole or probably put up a fight and send one of them hurtling away the bigger the light year trivia time time runs differently near and inside a black hole and this has a lot to do with gravity the nearest black hole to earth is 1600 light years away don't worry friends that's too long a time this is me zooming out I am the meteorite don't take me for a ride cuz I didn't turn into me to your ha I passed through the atmosphere of the earth no don't get scared cuz I then turn into me to your ride that's right haha very well mr. meteorite let me simplify your poem for my friends out here come we'll talk about meteoroids meteors and meteorites today zoom in a meteoroid is a small rocky solar object found in the asteroid belt between Mars and Jupiter which is often known as the solar junkyard when the molecules around the meteoroids rub against them they start burning when this burning meteoroid passes through the Earth's atmosphere it is called a meteor and when that meteor survives through the atmosphere and collides with the Earth's surface it's called a meteorite a meteoroid a meteor and a meteorite haven't you seen shooting stars Wow well those are actually made yours some meteors burn brighter than the rest of known as fireballs some fireballs appear even brighter than the planet Venus there's a small percentage of meteoroids that follow a particular path to the Earth's atmosphere and then back out again and they are called grazing fireballs about 25 billion meteors enter the Earth's atmosphere every day but most of them often burn up giving out 1 million kilograms of dust per day that settles on the Earth's surface so who knows the dust around you could be from space the meteorites are classified into three types the stony ones the ones that have iron in them and the magnetic ones triviatime asteroids apparent bodies of meteoroids nearly 500 meteorites reach Earth's surface every year out of which only 5 to 6 reach the scientists for their study I am the meteorite I used to shine so bright this earth is such a plight I am the meteorite I am the meteorite I used to shine so bright this is me you're moving out hey there oh don't worry this is not real I was just watching a movie hey friends the dinosaurs are extinct but the myth surrounding them aren't so why don't we bust some Dynamix today zoom in the word dinosaur is misinterpreted as terrible lizards well dinosaurs were neither terrible nor lizards the actual meaning of the word dinosaur is fearfully great well many think that dinosaurs were huge but you'd be surprised to know that Microraptor is the smallest species discovered yet it's a gross size dinosaur from China many believe that humans and dinosaurs coexisted dinosaurs became extinct about 65 million years ago whereas the first traces of human beings were just 6 million years old I know it's kind of funny but a myth says that the dinosaurs died because mammals eat their eggs that's not true because the mammals that lived at that time were far too small to eat their eggs probably just 2 grams see that well that's a pterosaur flying reptiles are often confused to be dinosaurs but that's not true marine reptiles such as please your sauce and eat fear sauce want dinosaurs dinosaurs were terrestrial beings now comes the biggest myth and asteroid impact alone resulted in the extinction of dinosaurs well the impact could have killed a lot of dinosaurs but many argue that the dinosaurs at that time were on the verge of extinction and the after-effects of the asteroid impact such as giant tsunami acidic rain and a cloud of dust played a major role in de-extinction live your time the first dinosaur bone discovered was thought to come from an elephant not all dinosaurs had scales of their bodies some had feathers to hope the myths surrounding dinosaurs have become extinct in your minds now wait for more myths to be busted this is me zooming out twinkle twinkle little star how I wonder what you are looks like the baby star has slept but hey you don't go to sleep because I'm here to tell you about different types of stars in space exciting isn't it so tell me how many stars do you think are there in the universe oh come on you can do it yes well the answer will be given at the end of this episode zoom in so there are different kinds of stars the big ones even bigger than the Sun small ones some very old ones and some new ones but did you know that they are classified in groups yes there are some specific types of stars the red dwarf stars they are relatively small in size compared to the other stars and therefore they born at a lower temperature which helps them have a long sustainable life some say a trillion years nearly 70% of the stars in the universe are red dwarf stars but hey since they don't shine so bright and gets difficult for humans to see them with naked eyes the yellow stars these are medium-sized stars and therefore burn at a medium temperature there are yellow dwarf stars as well that are not giant stars our Sun is one of them these stars become quite large just before they completely start running out of fuel the Sun too will completely lose its fuel someday but don't worry that won't happened before five billion years blue giant stars as the name suggests these are big stars and hence burn at a high temperature leaving them with a short span of life from ten thousand to a hundred thousand years most of the stars you see in the sky are blue giant stars when these stars die unlike other stars they don't shrink but explode and this type of explosion illuminates the entire sky there are all sorts of other stars like giant and supergiant stars which are extremely big have the shortest lifespan and shine the brightest trip your time every sad that you see in the sky is actually bigger than the Sun Proxima Centauri a red dwarf star is the nearest star to earth after the Sun so remember the question I asked you how many stars do you think are there in the universe well the answer is a hundred billion isn't that a shocker I can see stars in your eyes so this is me zooming out whoa I got to be more careful oh hello friends I am in space today but you know why look to tell you about these magnificent solar objects whew comments let's zoom in comets are one of the most rare objects in the solar system often known as the dirtballs of the solar system that's because they are made of dust and ice wrapping themselves around a small rocky core astronomers believe that comets are leftovers from the beginning of the solar system but hey they don't look like leftovers at all they appear magical when they reflect light from the Sun that's right comets do not have their own light they are reflectors of light when a comet travels towards the Sun the radiation and heat caused solar winds which often blow the gas and dust of the comet and therefore it appears as if the tail is behind the comet and when the comet travels away from the Sun tail is formed in front of the comet well have you ever wondered where are comets usually found yes yes they do orbit around the Sun mostly but they spend billions of years in the Kuiper belt or in the old clouds the Kuiper belt is found beyond the orbit of Neptune the earth clouds are found in the outermost reaches of the sky and comets livia because it's cold yeah unfortunately they don't live long once they enter the warmer part of the solar system traveling through the inner solar system eventually kills them and after several thousand years they melt triviatime I know you wouldn't but if you ever plan to go inside a comet you'll be hit by microscopic pieces of dust the name comet was given by Aristotle meaning hair of the head hey all my teeny-tiny friends the most famous comet the Halley's Comet will appear in the sky in 2061 but don't worry you don't have to wait that much to see me the next time this is me zooming out ooh it's dark here and I can't see you oh wait hey there wonder what we do without lights right so come on let's talk about lights today zoom in light is a form of energy made of photons a photon is the smallest unit of visible light now you ask me how does light travel well light is unique as it behaves both like particle and a wave that behaves differently with different kinds of matter if light hits an object and passes through it that object is known as a transparent object let's do one thing take a glass of water and switch on a torch see the light passing through well this proves that water is transparent there are certain objects through which light cannot pass and it changes its spot after hitting the object these objects are called opaque objects such as wood the mobile you are using right now and you as well hmm yeah humans are opaque as well some objects allow light to pass through them partially and they are known as translucent objects such as plastic butter paper and frosted glass and do you know what travels the fastest no not a space rocket well it's light in vacuum where there's no obstacle light travels at the speed of more than 0.1 million miles per second okay so the distance between the Sun and Earth is 93 million miles but it takes only eight minutes for light to reach the earth that's a whopping speed isn't it when light travels through different mediums it slows down and sometimes bends and this bending of light is known as refraction take a beaker filled with water and place a pencil in it now look carefully do you see a bend in the pencil no no the pencil didn't bend the light race just got refracted that's why you see the pencil Bend trip your time did you know that humans have bioluminescent which means that they emit light but their glow is 1000 times weaker than what the naked eye can register light takes approximately 1.2 seconds to reach the moon from the earth so friends did I not light up your tickling brain cells today hi friends did you just see that mighty beast well that's a sharp Hey that's not done I'm no beast doctor by Knox I mean look at my wife and look at me I'm a tiny little bean oh I'm sorry mr. Schock I was kidding I know you're not a beast but a lot of people think you are so why don't you clear that myth today my friend that's a good idea friends wanna bust some myths about sharks today I know you do come Suman it is said that most sharks are man-eaters and they deliberately hunt humans which is not completely true bull sharks tend to eat fish or invertebrates such as squids or clams if sharks happen to give humans it's mostly because of mistaken identity sharks grossly mistake humans to be some fish or another animal I'm sure you would have heard the Sharks have lots and lots of sharp pointed teeth well not all sharks have icicle like deep the basking shark has tiny teeth which it does not even use for hunting or feeding and the horn shark has smaller like teeth which is used to crush it's hard shelled prey it is often believed that sharks are indiscriminate killers but most of the times they are victims of massive hunting for their fins which is made into shark soups people claim that shark fins are tasty and have a lot of nutritional value which is absolutely untrue shark fins are tasteless with absolutely no nutritional value and if you think sharks have no predators you're wrong humans are their biggest predators if you actually look at numbers you'll be surprised to know that sharks kill approximately 6 humans in one year whereas humans kill about 100 million now that's called being indiscriminate sharks also help a lot in maintaining the balance of life since they are the top of the food chain they keep the marine population in check trivia time there are approximately 500 species of shark out of which white sharks tiger sharks and bull sharks are the most dangerous ones sharks have an extremely strong sense of smell almost two-thirds of its brain is dedicated to the sense of smell so friends now you know that sharks are a lot more than they are scary teeth you're right dr. Vioxx thanks for clearing the silly myths about me I owe you one oh come on let's drink some soup really not shark fin soup so this is me zooming out hello kids won't it be great if we could just pack up bags and keep flying from place to place hey you can't do that because you don't have wings like me oh yes you're right but there's one major difference between you and my friends out there and that is you're a migratory bird silly oops why don't that strike me doesn't matter you go take your flight and I'll tell my friends all about birds like you oh so special dr. Bai knocks come friends let's know more about migratory birds zoom in migratory birds are those birds that travel from one place to another at regular intervals over long distances and they migrate to escape the cold harsh winter weather in search of food and a warm cozy shelter there are various types of migratory birds resident birds pigeons and doves are good examples these birds just don't migrate they are able to find food and a warm shelter where they are staying we might not travel a lot dr. Bai Knox but we do spread love all around from place to place short distant migrants Robin's a shot distant migrants as the name suggests these birds move only a short distance from lower elevations to mountainside hey but don't you mistake me for a nightingale I might look like one but I'm not okay oh my friends won't we are very smart aren't you guys medium distant migrants these birds travel over distances that covers several states they don't really travel a lot but not that they won't travel less isn't it mr. bluej hmm you seem to know me quite well dr. Bai knocks but there's one more secret about me you wanna know sure tell us we are all waiting I'm quite mischievous dr. binocs because I hunt more than I Kelly's long distant migrants these birds travel typically from United States and Canada to wintering grounds in Central and South America the Arctic Tern is an example of long-distance migrants and I am the record holder for covering the longest distance of 44,000 miles owned by that's huge just to let you know the circumference of the earth is approximately 29,000 miles so imagine how much these birds travel trivia time before migrating many birds enter a state of hyperphagia where the hormone levels compel them to drastically increase their body weight to stow fat to use as energy while traveling and some birds also have the ability to sense the Earth's magnetic field to help them navigate so I need to travel now wait till I come back next I feel plants are the nicest beings on this planet they never harm anyone rather they get eaten all the time oops I guess some eat too and that's why I am here today to tell you about plants that eat meat come with me human plants that capture praise such as insects spiders lights and each meet for their survival unknown as insectivorous or carnivorous plants most of the carnivorous plants live in wet boggy areas where the soil doesn't have much nutrients they derive the nutrients from their preys whatever little nutrients available to them through soils they have a strong digestive system which helps break down complex food items the different types of carnivorous plants are pitfall traps popularly known as pitcher plants they are pitcher plants because they look like pitcher shaped vessels filled with fluid the insect is lured by the syrupy fluid and just when they come to drink it they get drowned some pitcher plants have a little them to trap their preys flypaper traps some flypaper traps have leaves covered with a sticky substance on which the prey gets caught these plants also digest their preys through their leaves other kind of flypaper traps use tentacle-like stalks covered with plants to trap and digest insects their stalks have digestive soup on them to absorb the nutrients snap traps venus flytrap is the most populous NAP trap here the plant has mouth like leaves that literally snap shut when an insect or spider lands on it there are some snap traps that are found underwater and they are known as waterwheel plants they do the same thing but under water bladder traps plants of this kind work in the most interesting way where there are sex on the plants known as bladders that create vacuum and suck the insect to digest it later lobster pots traps the blunt-force knows it's insects with its sweet-smelling nectar once the insect is trapped inside it sees light shining through the leaves which looks like exits to escape the insect travels towards the light which is nothing but another trap this is the plants way of actually misdirecting the insect to the inside of the picture where it is caught and eaten by the digestive liquids triviatime some pitcher plants are so large they can catch and consume rats and frogs some carnivorous plants reflect ultraviolet light to attract their preys hey don't go there wait I'll help you so this is me zooming out oh who's that Hey you're disturbing the air around us oh sorry I know I'm farting a lot today oops hmm guess you took in a lot of carbon dioxide for lunch yesterday y'all could be did you just hear them friends oh no not their father and that reminds me that I need to tell you about the process of excretion in plants come with me just like humans plants to feel the need to remove all sorts of waste material from their bodies however plants have a much simpler process of excretion hey did you know that plants threat well yes just like humans have sweat glands plants have small openings under their leaves called stomata that release water and oxygen just how the pose of your body released sweat but their waste material is a lot more useful than ours haha plants also released waste by accumulating it in the vacuums of aging leaf cells the leaves then fall off eventually removing the waste material this process is known as abscission don't you sometimes have dry skin that eventually falls off yep kind the same have you noticed leaves changing their color in autumn this happens mostly because of the waste pigments that start getting stored inside the leaves see the sticky fluid well this is another kind of waste produced by the plants which is often used out from the bark of trees apart from the sticky fluid there are other waste products like resinize gums and latex but hey you got to be careful because sometimes these products can be poisonous but most of the other times they are quite useful for example latex is used to produce gloves and clothing triviatime the bark of a willow tree produces a chemical that helps in the making of aspirin a medicine for pain and fever oak leaves turn brown due to the waste material in them so friends plant more and more trees because they are the reason why you can breathe breathe in breathing out that's what I say throughout breathe in breathing out that's what I say throughout hmm oh so you've been watching me work out a rather breathe in and breathe out whoo this is tiring so anyways why don't we talk about breathing today still can't get a hint well today we talked about the human respiratory system zoom in alright do this right now I'm watching you just out running wherever you are run run run run run run now stop isn't your breathing heavy well that's because right now your body needs more oxygen to breathe and you get oxygen from the air around you without oxygen you'd be like a car without fuel a waterless pool and wouldn't that be uncool one of the major reasons why you're alive is oxygen so take a deep breath in when you breathe in you take an oxygen present in the air the air that passes through your nostrils there are tiny hair present in your nostrils that obstruct all the dust particles then the air travels to the windpipe also called the trachea which filters the air inhaled the trachea branches out to two tubes called bronchioles a called cilia move back and forth moving the mucus inside the mucus is a sticky substance that collects germs and other particles that might harm the lungs bronchi then carry air into each lung the right lung has three lobes whereas the left lung has two loads the left lung is slightly smaller in size to give space to the heart these lobes are filled with small and spongy air sacs called alveoli where the exchange of oxygen and carbon dioxide happens it is here the blood picks up oxygen and lets go off carbon dioxide just beneath the lungs there is a dome-shaped muscle called diaphragm that contracts when you breathe in and expands when you breathe out it also separates the chest cavity from the abdominal cavity triviatime the lungs are the only organs that can float on water a person breathes approximately 20,000 times in one day so friends can't you just cast and grasp all the facts this is me zooming out happy Halloween my friends hmm I know it's not Halloween today but can you guess what I'm going to talk about he s that's right bones zoom in hey don't be scared that's not a ghost that's just how your skeletal system looks like come let's talk a little more about the bones in your body let's start with the head cranium this is the cranium it protects the brain from bumps and knocks mandible the lower part of the skull is called the mandible it is the largest and the strongest bone of your face scapula it is a triangular shaped bone that is protected by surrounding muscles it is commonly called the shoulder blade rib cage the rib cage protects your heart and lungs it is actually very delicate and can be damaged by accidents sports or even a powerful sneeze the arm consists of three large bones the humerus bone forms the upper arm the radius and the ulna are the two bones which bond the lower arm you have one radius and one ulna in each arm the radius and ulna bones connect between the elbow joint and the wrist your palm consists of three groups of bones carpals metacarpals and challengers femur the femur or thighbone is the longest heaviest and strongest bone in the entire human body all of the body's weight is supported by the femurs during many activities such as running jumping walking and standing patella the patella is also known as the kneecap it is a thick circular triangular bone which covers and protects the surface of the knee joint tribulus the fibula is the outer and cleaner bone of the lower leg it's brain function is to provide attachment for muscles however it doesn't give much support and strength to the leg tibia the tibia is a large bone located in the lower leg of the human body it is also known as the shin bone and is the strongest weight-bearing bone just like your palm your foot also consists of two groups of bones tarsals and metatarsals did you know that half of your body's bones are in hands and feet and an infant has 300 bones whereas an adult has 206 bones this is because some smaller bones fused together to form bigger bones okay kids got to go now hey hello friends oh no I guess that's a tsunami come let me tell you all about it zoom in tsunamis are caused by sudden movements of the ocean flow due to earthquakes landslides on the seafloor land slumping into the ocean large volcanic eruptions or a meteorite crash on the ocean floor when an earthquake a landslide or a volcanic eruption occurs on the sea or ocean bed a vertical jolt is created which displaces the bed and causes extreme tension in water the water is pushed upwards but gravity tries to pull it down this causes an upsurge in the water levels and the waves got moving away from the point of tension tsunamis are barely felt as a ripple on the ocean surface as the water is quite deep but as and when those wave reached the land the water becomes shallower and the waves constantly increase in height they hit the shore and all my cause a lot of destruction it just said the first wave of a tsunami is not the strongest but the successive waves are bigger and stronger oh and tsunamis can travel at a speed of about 500 miles per hour which is almost as fast as a jet plane and that's why tsunami waves are called killer waves deadly isn't it trivia time did you know that a tsunami wave can be less than 30 centimeters in height and can pass off unnoticed if you get stuck in a tsunami don't swim because the currents will pull you in the opposite direction just hold on to a floating object and be safe so here's the deal go watch this video to know more about earthquakes after all that's one of the major causes of a tsunami this is me zooming out hello it's quite windy today so I thought I'll take a quick fly it sure is windy you mean hurricane do you mean fly oh okay well that reminds me that today's topic is hurricane whoa a hurricane is a huge storm that generally forms over warm ocean waters near the equator the warm air above the ocean Rises upward thus creating an area of low pressure below air from the surrounding areas pushed in and try to fill the area with low air pressure which now becomes warm and moist and rises to as the moist air rises the surrounding air again tries to fill in and this process continues till the water in the air calms clouds soon the clouds and winds that around fueled by the oceans heat and water vapor therefore hurricanes could also be called giant engines that use warm and moist air as their fuel when we see from the top hurricanes can be as huge as 300 miles wide the center of the hurricane is called the eye of the hurricane which is the calmest part the eye wall surrounds the eye where the most damaging winds are found it can range anywhere from five to thirty miles then comes the rain bands which surround the eye wall these bands are series of dense clouds that give a pinwheel like appearance to the hurricane which range from 50 to 300 miles hurricanes are divided into five categories depending on the speed of their wind here take a look category three four and five are the most dangerous ones rivia time a huge hurricane can release energy equivalent to ten atomic bombs per second degree hurricanes in the Pacific Ocean unknown as typhoons so this is me coming out
