By “verified” I take it you meant it has been put through a hundred... a thousand tests and the results are always the same. Problem is what about the 1001st test, the 1002nd test and etc. Will it still give the same result?
It’s always easier to disprove a claim because it only need to fail once. To prove a claim to be true, there’s no end to the test.
Many claims that had withstood the test of time has turn up false after new findings came to light. One particular example is the one about the sun going around the earth. For 1,500 years, people believed in a geocentric universe, where all the stars and planets revolves around earth.
1,500 years, it looks like a sure thing... but it was not.
