“Some people believe holding on and hanging in there are signs of great strength. However, there are times when it takes much more strength to know when to let go and then do it.” -Ann Landers
The history of physics is littered with brilliant ideas that have revolutionized how we look at the Universe… and have been discarded entirely because they’ve failed to describe reality. Theories like the Tired-Light alternative to relativity, the Steady-State alternative to the Big Bang, and even the Sakata Model alternative to the quark model of particles have come and gone, with practically no one working on them today. As it should be.
But many ideas that the science has overwhelmingly spoken against continue to linger on, as their adherents continue to double down on investing in them, despite failure after failure after failure. At the end of the day, physics is an experimental science, and no matter how beautiful, elegant, or compelling your theory is, if it fails to have its predictions borne out by experiment and observation, it must be set aside as unsuccessful.
