Astrophysicist Neil deGrasse Tyson confronts Moon-landing denial during a podcast appearance, rejecting scepticism with physics, scale and evidence. From lunar rocks and Saturn V maths to the implausibility of a 400,000-person conspiracy, he explains why Apollo isn’t belief-based history. The argument matters because mistrust survives not through gaps in proof, but misunderstanding, and modern spaceflight puts the debate in perspective.
