# Flat-earther tries to prove planet isn’t spherical

• YouTuber D Marble posted the video in an attempt to discredit proven science
• He took the DIY tool onto a flight from North Carolina to Seattle in a strange stunt
• Self-titled ‘realist’ expected pilot to tilt the nose to ‘compensate for curvature’
• When the spirit bubble remained central he claimed it proved the earth was flat

A self-titled ‘realist’ has tried to prove the earth is flat by taking a spirit level on a plane to back his outdated theory.

YouTuber video blogger D Marble attempted to discredit scientific fact by taking the DIY tool onto a flight from North Carolina to Seattle.

He was expecting the pilot to tip the plane forwards to ‘compensate for the curvature’ of the earth – but when the spirit bubble remained central, he claimed it proved the world was flat.

But people have branded the flat-earther’s stunt a ‘perfect combination of brilliant and stupid’ and suggested that he should have looked out of the window to see the curvature of the horizon.

The scientific explanation for why the bubble remained central is that the plane nose did not dip because gravity was pulling it towards the earth and it was generating lift to pull away.

D Marble said: ‘We’ve been living a lie all this time and the planet is actually completely flat.

‘This is a new experiment for the scientific community. Grab a spirit level and take it on the plane with you.

‘If we’re living on a spinning ball or globe, according to curvature maths, the plane should be constantly dipping its nose forwards.

‘I’m going to take my spirit level on to a plane and record fact that bubble stays perfectly centered. Proof that the earth is flat.’

The video blogger said: ‘I recorded a 23 minute and 45 seconds time-lapse, which by those measurements means the plane travelled a little over 203 miles,’ he said.

‘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.’

Matty Young tweeted: “You think he would have looked out the window at the curve in the horizon like at least one time.”
