That’s Matt Walsh in the thumbnail, not Joe Rogan! Matt defended the reality of the moon landing to Joe, and did a good job standing his ground, despite not having a scientific background.
It’s a more straightforward thing to shut down if you have a STEM background since you can address the claims directly, e.g., yes the Van Allen belt exposes you to radiation from charged particles when you pass through, but the Apollo astronauts passed through it at 25,000 mph. Radiation harm is dose dependent, which is a function of intensity and time. It’s not good for you but similar to getting a chest x-ray, totally non lethal for the time spent in it. The overall dose of radiation was higher after leaving the Earth’s vicinity since cosmic rays aren’t being blocked by the atmosphere and magnetosphere, and they spent much more time out in space for the week getting to the Moon and back.
