The Earth is n’t flat . This presumably does n’t come as tidings to you , and why should it ? dry land ’s roughly spherical nature has been known about since the time of the Ancient Greeks . It ’s bewildering , then , to see various " celebrities"declaring online that Earth is indeed flat , claiming that NASA has been keeping this secret from us for decades . So what just is going on here ?
Most lately , B.o . B , an American knocker , has effused a series ofutterly ridiculous claimson Twitter . Although he start out with lecture of human cloning midpoint , he quickly turned his centering to the idea that we are all remain on a relativelytwo - dimensional worlddrifting through space like a cosmic Frisbee . Famed astrophysicist and science communicator Neil deGrasse Tyson was quick to answer .
At nowadays , the two areengaged in a knock battlefor either side , which should give you some perceptivity as to how nonsensical the intact conversation is . While it ’s pretty effortless to bear witness Earth is n’t flat , that has n’t stopped madcap conspiracy theories cropping up – B.o . B is just another galley slave in the ranks of the International Flat Earth Society .
The Draw of Conspiracy Theories

This organization , founded in the nineteenth century , exact to have intercourse the “ truth ” about our major planet , and regard scientists aswitch doctors pluck off a mammoth fraudulence . In 2010 , its United States President said that he accepts the scientific discipline of both man - made mood modification and phylogenesis , but when it make out to Earth , he ’s convinced it ’s matte .
The society ’s phallus , who also conceive that the Sun and Moon are just 4,800 kilometers ( 3,000 miles ) above us , have never quite explained the motives behind a huge confederacy theory to hide the fact that Earth is flat . Who would gain from such a comprehensive cover - up ?
mass are line to conspiracy theories , though , and the Internet has only help to accelerate their spread . They give certain multitude a sense ofsecurity , control and comfortthat they have n’t found in the innate domain around them . By only discourse with others that harmonize with them in “ echo William Chambers , ” any contradict views are filter out out , and they becomeincreasingly entrenchedin their own views . Perhaps this is what drives contemporary Flat Earthers .
Shadows and Stars
Today , NASA and other space delegacy have built up abeautiful library of imagesof Earth , clear express that it is round – or technically abumpy spheroid , an odd sphere with a bulge at its Equator . Naturally , matt Earthers always assume that these images are photoshopped . as luck would have it , there are quite a little of other ways to demo the Earth ’s rotundness .
A Grecian uranologist by the name ofEratosthenesclearly show Earth was circular just over 2,000 year ago . He realized that rays of sunlight are gain Earth at the same degree , but because Earth has a curve , the distance of shadower at different locations across Earth are n’t the same .
By look this shadow length modification between two cities – Alexandria and Syene – he pass on an estimate for the circumference of the Earth : 46,620 klick ( 28,970 miles ) , which is only 16 percent larger than the actual value .
Flat Earthers often say thataccess to Antarctica is restrictedfor our own guard ; if we thwart over this frosty closed chain around the edge of the matt disc , we ’d shine off into infinite . Of course , humanity has circumnavigated the globe plenty of times , and no - one ’s fall off into numberless swarthiness just yet .
If you reckon up into the sky and recognise a star , you could track its position every nighttime . If you then begin to move forwards towards the view , you ’ll notice the star look further behind you each and every night . If Earth was monotone , you ’d be able to always see it . SInce Earth is round , this mavin will eventually sink and disappear below the celestial horizon .
It ’s Fundamental Physics

All planets in our Solar System – and the thousands of exoplanets we ’ve discovered far beyond our little corner of the galax – are roughly globose . It ’s afundamental feature of physics ; ethereal bodies of a meaning mass are spherical due to the outcome of gravitational force , which acts in all direction to pluck objects towards the center of mass .
And if any more proof was needed , we also have time of year and chicken feed ages . The amount of sunlight hitting parts of the major planet changes from time of year to season , fromicehouse existence to greenhouse creation , and this is completely dependant on thedegree of tilta orbicular Earth has with respect to the Sun .
Ultimately , it is believably due to the fact that it isso ego - evidentthat Earth is not flat that people are talk so much about B.o . B ’s recent epiphany . That , and the fact that Neil deGrasse Tyson responded using the medium of rap .
