A conspiracy theorist who believes the earth is flat has taken a spirit level to prove his point.

What is the Ig Nobel Prize and who won it this year?

D Marble said that scientists had produced facts and figures in the past to prove that Earth is round, but not much evidence has been produced recently.

So he armed himself with the spirit level for his flight from North Carolina to Seattle.

Comments on his video ‘Flat Earth: Spirit Level Flight Experiment’ are disabled.


Writing on YouTube he said he wanted ‘to monitor whether or not the pilot would dip the nose of the plane to compensate for curvature.’

Is this proof that the earth is flat?

He said: ‘I recorded a 23 minute & 45 second time-lapse which by those measurements means the plane travelled a little over 203 miles. According to curvature math given to explain the globe model, this should have resulted in the compensation of 5 miles of curvature. As you’ll see there was no measurable compensation for curvature.



The bubble doesn’t stay centered due to gravity. Understand that gravity is a still just a theory. Consider how gravity supposedly comes about…a molten metal core which somehow becomes magnetized. If that is the case, then metal foundries should all be magnetized…should they not? Also, how does magnetism effect an air bubble inside a glass cylinder containing a liquid more saline than water?

‘No more defending what we know to be true! Now we take the fight to the enemy! #FEOffensive’
