If you look at Physics, the reason no one is really capable of creating what they call a Unified Field Theory that would make everything they know of physics work together and create a prefect system that explains everything, is because Physics already is chock full of leaps of faith. That's why certain things that can and should be taken for granted are called Theories, because even though there's little to no chance that they're wrong, they're not unquestionably proven.
Black holes and dark matter fall into this category and in one way or another don't really play well with Unified Field Theories, because they're made up concepts that are almost definitely real, we just can't find definite proof of them in the places we think they should be, just a hole where nothing else seems to fit, so we assume they're there.
But when we do that, we don't have the details, so we estimate and sooner or later an equation is going to come out wrong because 500 estimates ago, we did something wrong.
>>91490781That's fair from a certain point of view, but that kind of comes back to a more conceptual version of the ship that sails from London to New York with every piece of it replaced along the way, and a new perfect replica being built out of the scrapped parts behind it.
Those parts of the ship are immutable, but can we really say that by their mere existence they create the idea of that ship?
What you're saying, in a way also implies no new ideas can be created, which while could be argued in today's world, begs the question of where the building block ideas came from, if ideas are impossible to create.
Pic unrelated.
