I need instances of people being wrong.?

Question by Colonel Sanders: I need instances of people being wrong.?
here is what I mean. A long time ago, we all once thought the earth was flat, that turned out to be very wrong. then we thought the earth was at the center of the solar system. also wrong. if you know of any other instances, I would like a corresponding date to go with it, if thats not asking too much.
here are some other examples i found:
“Airplanes can barely keep themselves in the air. How can they then carry any kind of load?”
– William Pickering, Astronomer (1908)
“Airplanes suffers from so many technical faults that it is only a matter of time before any reasonable man realizes that they are useless!”
– Scientific American (1910)
“No flying machine will ever fly from New York to Paris.”
– Orville Wright.
“Airplanes are interesting toys but of no military value.”
– Marshal Ferdinand Foch [Professor of Strategy, Ecole Superieure de Guerre] (circa 1911)
He was Supreme Commander of Allied forces, 1918
“Aviation is good for sport, but for the Army it is useless!”
– Marshal Ferdinand Foch
“To throw bombs from an airplane will do as much damage as throwing bags of flour. It will be my pleasure to stand on the bridge of any ship while it is attacked by airplanes.”
– Newton Baker, US minister of defense (1921)
“The only thing that will happen is that the vessel will sink, and suffocate the crew”
– H. G. Wells, English writer(1902) (Submarines had been used since ca. 1850)
“Even if a submarine should work by a miracle, it will never be used. No country in this world would ever use such a vicious and petty form of warfare!”
– William Henderson, British admiral(1914)
“If two people can’t see each other, then it’s impossible to communicate”
– Unknown roman warfare expert (63 ad.)
“Samuel Morse most have lost his mind if he believes in this idea himself!”
– Senator Oliver Hampton Smith, (1842)
after having seen a demonstration of Morse’s new invention.
“It is only righteous that Joshua Coppersmiths, who has tried to find investors to finance the development of a so-called telephone, is arrested for fraud!”
– An article in the Boston Post (1865)
“The radio has no future!”
– Lord Kelvin, British Mathematician(1897)
“Use your time on something useful. All radios this country will ever need can easily fit on my desk!”
– W.W. Dean, director of the American phone company “W.W. Dean”(1907), to Lee DeForrest (one of radios first pioneers)
“Radio is just a fashion contrivance that will soon die out. It is obvious that there never will be invented a proper receiver!”
– Thomas Edison
“The wireless music box has no imaginable commercial value. Who would pay for a message sent to nobody in particular?”
– David Sarnoff’s associates in response to his urgings for investment in the radio in the 1920s
In all of those examples, they were VERY wrong. but they were all military examples. I was hoping for some like the earth, in which we all, as in the whole planet, believed something to be true, then it turned out wrong. But I wont be picky, i’ll take anything you can find.
here is another.
640K ought to be enough for anybody.

There’s quotes like that about TV also. And what about the guy who had his own TV show and didn’t book Elvis when he had the chance? Not sure if it was Ed Sulivan?
Also for centuries they bound the feet of little girls in china. Causing them horrible pain.
What about slave owners who convinced themselves that their slaves weren’t ‘real people’?
What about men who said women couldn’t be doctors, or vote with intellegence?
