Flat Earther spent £15k on experiment trying to prove theory but ended up doing the opposite

A Flat Earther spent a staggering amount of cash in an attempt to prove the world is flat - only for the opposite to happen.

Despite ample amounts of evidence proving that our planet is in-fact spherical, the Flat Earth movement is one conspiracy theory is one that just refuses to go away.

Adamant that we're being lied to by scientists, Flat Earthers have been known to go to extreme ends in order to find evidence for their 'theories'.

One of the more famous cases of this involved the late YouTuber Bob Knodel, who splashed out an almighty $20k (£15,150) in an attempt to find evidence for his beliefs.

His experiment was shown in the documentary Behind the Curve, which you can watch the trailer for below:

Released on Netflix back in February 2019, Behind the Curve followed prominent Flat Earthers such as Mark Sargent who outlined their beliefs in the documentary.

Several scientists and astrophysicists also appeared in the film to give their views on the Flat Earth movement and its longevity.

During his segment in the documentary, Knodel decided to go beyond arguing his case and prove once and for all that scientific consensus from the last couple of centuries was wrong.

What was Bob Knodel's Flat Earth experiment?

In order to prove his theory that the Earth was in fact flat, Knodel created an extravagant experiment which set him back tens of thousands of dollars.

To conduct his experiment, Knodel created a laser gyroscope which he believed would debunk the idea that our planet is round.

To put it plainly, Knodel used a camera to film through two holes - which were both the same distance from the ground - while a person stood on the other side was shining a torch at the camera.

Below is a diagram of the YouTuber's set up for the experiment:

Knodel claimed that if light could be seen with the camera, and that all of the holes in the fence and his torch were at the same height, then we had definitive proof the world was flat.

However the experiment didn't go entirely to plan, with Knodel left muttering 'interesting' to himself after no light was able to be seen.

He would later attempt to explain the findings in Youtube video, saying: "What we found is, is when we turned on that gyroscope we found that we were picking up a drift. A 15 degree per hour drift.

"Now, obviously we were taken aback by that."

Admitting the results were 'kind of a problem', he continued: "We obviously were not willing to accept that, and so we started looking for ways to disprove it was actually registering the motion of the Earth."

Knodel passed away on 6 April, 2023, aged 62.
