Synopsis

Special relativity has long fascinated scientists and the public. Yet in popular accounts, accessibility often comes at the expense of nuance, creating misconceptions—even among students—that obscure deeper connections.

In this talk, I will “pedantically” revisit two common but misleading statements in special relativity and show how their careful reexamination opens doors to surprising insights into the Higgs mechanism and Hawking radiation. The two statements are:
(i) “A photon experiences infinite time dilation.”
(ii) “The speed of light in vacuum is the same for all observers.”

The broader message is simple: questioning familiar statements can reveal profound new insights, and sometimes the path to new physics begins with a small act of pedantry.
