At 0:57, a fudge factor is added to an equation in a non-deductive model (Einstein's general relativity), then at 2:16 the fudge factor is removed:

SPACE'S DEEPEST SECRETS Einstein's "Biggest Blunder"

"A fudge factor is an ad hoc quantity introduced into a calculation, formula or model in order to make it fit observations or expectations. Examples include Einstein's Cosmological Constant..."

Can one add a fudge factor analogous to the cosmological constant to the Lorentz transformation equations? One cannot, and the reason is simple: Special relativity is DEDUCTIVE (even though a false postulate and an invalid argument spoiled it from the very beginning) and fudging is impossible by definition (one has no right to add anything that is not deducible from the postulates).
