Watch now | In this thought-provoking discussion, Malcolm and Simone Collins sit down with renowned physicist and science communicator Sabina Hossenfelder to explore some of life's biggest questions through the lens of physics. Hossenfelder, author of "Existential Physics: A Scientist's Guide to Life's Biggest Questions," shares her insights on free will, the nature of time, and the challenges of understanding reality.
"Newton, for example, entertained the idea that the gravitational force was transmitted in the ether ...".
Has she ever read Principia or any of Newton's works? Like most of the mathematicians who call themselves 'scientists' I doubt it. Here's what Newton actually said about Gravity.
From Gwynne's introduction to true philosophy page 155.
"In his third letter to Bentley [An English pastor who had studied Principia and was using it extensively in his lectures], Newton expounded his meaning [of gravity] more fully in this, in the circumstances, remarkable passage (Newton to Bentley 17th January 1693 - See Newton's correspondence, Royal Society edition, volume 3, page 253.)
'It is inconceivable that inanimate brute matter should, without the mediation of something else which is not material, operate upon and affect the matter without mutual contact; as it must do if gravitation, in the sense of Epicurus, be essential and inherent in it. And this is the reason why I desire you would not ascribe innate gravity to me. That gravity should be innate, inherent and essential to matter, so that one body may act upon anything else - by and through which the action and force may be conveyed from one to another, is to me so great an absurdity that I believe that no man who has in philosophical matters a competent faculty of thinking can ever fall into it'
Newton's Principia is largely an incomprehensible and in places simply wrong mathematical treatise that has no philosophical worth as it fails entirely to explain gravity. There is no mention of the aether in it. At all.
In Principia Newton and Halley fudged the data to calculate the orbit of the great comet of 1680 using a mis-identification of Eros as one of their data points [page 552 and onwards in my copy of Principia. I suggest Hossenfelder actually reads it as clearly she hasn't done so yet]. This is why they cannot predict the exact year of the comet's return.
The reason physics is the mess it is in is simple. The current crop of physicists have no idea about the origins of their own discipline. None of them have ever heard of let alone read 'De revolutionibus orbium coelestium', 'Mysterium Cosmographicum', 'Astronomia nova' ,'Harmonices Mundi', 'Dialogue Concerning the Two Chief World Systems' or 'Principia'. Had they done so they might actual come to the realisation they have been thoroughly duped.

Amazing!
