Who do you think knows more about space, someone who is alive today or someone from ancient Greece? Apparently the answer depends on who you are talking about specifically, because, boy howdy, this whole "Flat Earther" thing has gotten out of control. And where there are people with insane ideas, there are people patiently trying to explain why those ideas are insane.
Once upon a time, someone existed who believed in Zeus, but still knew the earth was round. Cut to the year 2017, and someone exists who can look at their phone and see their own head via satellite, but they're skeptical about the whole "round earth" thing. Humans are strange.
Aristotle didn't have a fancy computer that he could re-post gifs on, but he did have the night sky. The night sky is worse, certainly, but Aristotle's view of the stars allowed him to reasonably ascertain that the earth was shaped like a sphere. He understood that the stars in the sky change positions based one's location on earth. Greek philosophers could also track the stars as they rotated around our planet.
Some people don't want to believe Aristotle. I guess they think they're smarter than he was. Instead, these people want to go on TV and debate astronauts on the shape of the earth, which is exactly what Mark Sargent, a prominent Flat Earther, did on Good Morning Britain.
Sargent explained that he believes the world is one large stage that was built by aliens, a bit like the Truman Show. Piers Morgan, who hosts Good Morning Britain, was understandably baffled.
Side note: Piers Morgan reacted to the 2017 Women's March by saying that he would schedule his own march to “protest the creeping global emasculation of my gender by rabid feminists," which is only slightly less ignorant than believing the earth is flat.
On Good Morning Britain, Morgan asked Sargent why so many people, people who secretly know the earth is flat, would be keeping that big of a secret. Sargent responded, asking, "You would break that story? Knowing the shockwaves that would ripple through our civilization?"
In fact Piers Morgan would love to report that story, just like he reported that Will Young, who suffers PTSD, actually suffers from WNTS (whiny needy twerp syndrome).
Sargent appeared on Good Morning Britain via a Skype feed, but the man tasked with responding to his claims, former NASA astronaut Terry Virts, was at the studio in person. Instead of taking the time to explain math and physics to Sargent, Virts simply pulled out a book for his counterargument. The book contained pictures he had taken from space. In the photos, the earth looks round.
I can't believe I have to do this. The remaining slides are some of the reasons why the earth isn't flat. I've excluded reasons that use math that no one wants to read and that I might not fully comprehend. I've included some digs at Piers Morgan for fun.
If the earth is flat, then what's up with the moon? We can all see the moon, right? And the sun? They're definitely both round. Or maybe I have a different definition of "round." Anyway, the moon is a hoax.
If you think the earth is flat, get on a boat and sail out to sea. Now sink your boat. Kidding :) Instead, look around you. With a far line of sight, you can see the earth bend. Also, if you keep sailing, you won't fall off the earth. Anyway, boats are a hoax.
Skeptics of a round world could also buy a ticket to go to China, spend the afternoon having an authentic meal, and then fly home. Back when people believed the earth was flat, you couldn't literally fly around the world. Now you can. Anyway, Chinese people are a hoax.
Finally, if the earth is flat, that means that every top scientist as well as every government in every country in the world is perfectly in sync about lying to the public. Human beings kill each other about banal crap every day, but for this one issue, every race, gender, and creed have come together in perfect harmony to spread a singular lie to all of humanity. Anyway, Piers Morgan is a twat.
