See how many of them you still believe
We ’ve already babble about one of the biggest science false belief that most of us still conceive – the estimate that humans only havefive sensation . As it bend out , there are plenty more to cover .
1 . Goldfish have a 3 - second memory

It ’s actually surprising that this one stuck around for as long as it did since it ’s pretty leisurely to disprove . Basic experiments do with goldfish establish Pavlovian conditioning . The Pisces the Fishes in the experimentation would receive intellectual nourishment under certain context ( ordinarily in connection with another object ) . After several instance , it became cleared that the Pisces the Fishes learned to associate the two together , prove that their memories last for at least several days .
2 . Everest is the tallest mass on Earth

Ok , this is a technicality , but it ’s a adept fact to know if you want to be a smartass . The height of a mountain refers to its distance from root word to breast . The superlative refers to the duration from ocean level to breast . So , with that in nous , Mount Everest might be the in high spirits good deal in the creation , but it ’s not the tallest . At 33,465 ft ( 10,200 m ) , Mauna Kea in Hawaii is taller than Everest which is “ only ” 29,029 ft ( 8,848 m ) . However , almost two - thirds of Mauna Kea is underwater .
3 . Lightning never hit the same stead twice
Over the years , this saying has taken on a more figurative import but there are still those who consider it literal . There is no reason why we should consider such a affair . Lightning fall upon the Earth anywhere from 50 to 100 or more times … per second ( different source claim dissimilar numbers ) . That ’s over 1.5 billion clock time per twelvemonth . The chances that one field would never be hit doubly are incredibly small . Moreover , we have it away for a fact that home that have been affect multiple times . Tall buildings are very good at attract lightning . The Empire State Building in New York gets fall upon dozens of times each year .
4 . the great unwashed in the Middle Ages thought the Earth was flat

really , it ’s been known that our planet is circular ever since the Ancient Greek clock time period ( and possibly even sooner than that ) . If you want to be even more precise , Earth is in reality an oblate ellipsoid of revolution because it is flatter at the poles than at the equator .
5 . shark do n’t get cancer
We already vote down millions of shark every year just to get their fins for shark fin soup . Now , sharks are also unfortunately hunted for their cartilage which can supposedly cure cancer . The problem is it ca n’t . At no power point did scientist believe such a claim , but the worldwide populace was more eager to indulge the fantasy because of the incredible electropositive effects it would have on company . However , now we have definitive proof of shark with tumour so the notion can be put to bed once and for all .
6 . Most of your body heat break loose through your head

Various reasons have been give for this approximation ( such as the lack of fat in your head compare to other body part ) . However , the truth is that you will lose just as much heat through your header as you do through the rest of your body , without accounting for isulation like clothing . However , unless you have a tendency to saunter naked through the nose candy during winters , your body is not adorn evenly . unremarkably , your head is the only exposed part of your body which is the simple ( and obvious ) answer to why it is cold than the rest of your body .
7 . Blood inside your body is blue

This one seems pretty obvious . After all , you may take care at your vein right now and see blood lead through them and they look dark , correct ? This lend credence to the myth that deoxygenate blood is blue , but as soon as it leave the body and is exposed to oxygen , it turns red . This is not reliable because human blood contains hemoglobin at all times , even when it does n’t contain oxygen . Hemoglobin is a red protein , so the descent in your body is actually a morose red . vein come out low due to how light is reflected .
8 . The Great Wall of China can be get a line from space

Another myth lay claim that the Great Wall of China is , in fact , the only valet - made physical object that can be seen from infinite . In this face , it is doubly wrong . It all depends on what you imply by space . In low orbit , the paries can barely be see , but so can a short ton of other poppycock we ’ve made . From further back like the moon , you ’ll be have trouble making out intact continents , let alone a wall .
9 . Chameleons can change colors to blend in

Chameleons are reasonably amazing and interesting . However , the idea that they camouflage themselves by blend into their backgrounds is a myth . In unretentive , there are multiple reasons why a chameleon would change color and it depends on the species . Their mood and their intention act a large role . If a chamaeleon is happy and court a lady chameleon , he ’ll change color . If he is tempestuous and getting ready for a engagement , he ’ll change color again . External factor such as temperature also play a role .
10 . Pluto is a satellite

Pluto lost its status as a planet a few years back , but some people did n’t get the memo and still conceive in the nine - planet solar system model . But why is Pluto a dwarf planet now ? Well , Pluto never really fit in with the eternal rest of the planets . It is far smaller than all of the other rocky planets . As our scope got better , we started discovering more and more target that were interchangeable to Pluto in size . Should they be counted as planets , too ?
Everything would have been okay as long as we did n’t find one physical object which is bounteous than Pluto . However , that is exactly what happened when we discovered Eris so a conclusion had to be made . If Pluto is a major planet , so is Eris ( and most likely a few others , too ) , which means that even if we still hold back it as a planet , the nine - major planet example would still be disused . That is why it was kick downstairs to dwarf major planet along with Eris , Ceres , Haumea and Makemake , and it is highly potential that they are not alone . We already have 100 of other potential candidates that want to be confirmed .
