Joe Bartolozzi asks what would convince a flat Earther
Watching Jack Gordon's rocket-launch trip, Joe moves from questions about satellites and thrust to why evidence may not change someone's mind.

When A Flat Earther Sees A Rocket Launch
Things we can learn from the video
Press to jump
- 1:25Joe asks how satellites and GPS could function if outer space did not exist.
- 3:33The rocket-launch reaction leads Joe to explain the fuel and speed needed to reach orbit.
- 17:15Joe argues that continuous footage into orbit could still be dismissed as CGI or AI.
- 31:02A question about thrust in a vacuum prompts Joe's explanation using Newton's third law.
- 32:41Joe suggests that changing the belief would also threaten a person's foundational identity.
- 34:16Gordon proposes sending Harvey's camera aloft on a weather balloon; Joe anticipates objections about lens distortion.
Justin Harvey watches a rocket launch and calls it a giant green screen. Joe Bartolozzi pauses almost immediately: how do you argue with someone who can dismiss the thing happening in front of him?
"When A Flat Earther Sees A Rocket Launch" is Joe's reaction to Jack Gordon's "I Took a Flat Earther to a NASA Rocket Launch." Gordon makes the trip with Harvey; Joe watches their encounters, stops to question the claims and occasionally heads off to look something up himself.
The practical questions give the reaction its substance. How would satellites and GPS work without space? Why does a rocket's path curve? At one point, Joe searches for ballistic missile trajectories to better understand the argument he's hearing. Later, when Harvey asks how thrust works in a vacuum, Joe points to Newton's third law: propulsion doesn't require surrounding air to push against.
But Joe's larger question is about what would count as proof. Harvey wants an unedited, continuous shot into orbit. Joe argues that even this could simply be dismissed as computer-generated footage. By the closing stretch, he suggests that accepting a round Earth would mean abandoning something foundational to Harvey's identity, not merely correcting a mistaken answer.
The upload has drawn about 1.4 million views in five days. In the comments, viewers discuss whether more demonstrations could help, while others pick up the geographical joke of flat Earth believers living all around the world.
Gordon finishes by proposing a weather-balloon flight carrying Harvey's camera. Joe is already imagining the next objection: the lens.

Same idea as the tweet of "There are flat earthers all AROUND the world"🥀
@Flying-SpinnersSee it on YouTubedome or donut earth is by far the funniest version of the flat earth theory
@danielsos9824See it on YouTubeif we ever eventually go to mars flat earthers are gonna say mars is flat too

Which of Newton's laws explains the action-and-reaction principle behind rocket propulsion?
Newton's third law describes equal and opposite forces, including those between a rocket and its expelled exhaust.
