This is the fault of the ego of man, not an invalidation of a theory.
This can be seen in ANY OTHER scientific discipline and community. They’re constantly re-evaluating the true age of this universe (hint: They’re pretty sure it’s greater than 6000 years). Hawking had to revise his cosmological constant and admit that he was wrong. Even Newton was wrong in his observations and calculations (but NOT his theory)>
Nobody wants to delay while other people publish from their work. That’s a fault of MAN, not science.
A thing I find ironic is that almost every constant (Cosmological Constant, Planck’s Constant, etc) is that they are a variable.
