Why No One Knows If Photons Really Are Massless - What If They Aren't?

Explore the intriguing question of whether photons truly have zero mass in this thought-provoking 13-minute video. Delve into the implications of potentially massive photons on our understanding of the universe, including the concept of maximum speed, causality, and observable cosmic phenomena. Learn why current experiments cannot definitively prove photons are massless and consider how a universe with massive photons might differ from our own. Gain insights into the relationship between advanced mathematics and physics, and discover how deepening your understanding of calculus can enhance your grasp of complex physical concepts.
