Refuting Phillip Dennis’s Errors in Physics, ASC, and Philosophy – Part 4
In this article, we will examine a particularly embarrassing mistake made by Phillip Dennis in his fallacious attempt to prove the one-way speed of light in all directions must be the same as the round-trip speed. As with all his previous attempts, we will find that Dennis committed the fallacy of begging the question. Namely, he tacitly assumed an equation that arbitrarily presupposes the one-way speed of light at the start. This was the same error made in his previous attempts that I refuted last year (Lisle 2024). What makes his latest mistake particularly embarrassing is that it has already been refuted over 100 years ago (Eddington 1923)! Moreover, it has been refuted multiple times in the last century – including in my book, the Physics of Einstein (Lisle 2018).
