It predicts that the universe will continue to expand at a particular rate.
- semantic nitpick for clarity -“it” isn’t the scientific method, “it” is scientists trying to apply that method to specific repeatable observations. Scientists predicted the CMBR, the speed of a feather falling in a vacuum, what it takes to land a rover on Mars, which vaccine will work … ALL OF IT.
The scientific method is believing in reality.
As I have said elsewhere on these boards, there are two meanings of the word "science", and these are often conflated despite being quite different.
Science (A) is a methodology for testing whether statements about reality are false.
Science (B) is a body of statements that have not been found to be false by science (A).
People who don't deal much with those who do science (A) as a career, often don't know, or don't stop to think, that science (A) is much of a thing. They don't need to; They learned some science (B) at school, and can look up any science (B) they need, so as far as they are concerned science (B) is all there is.
And from that perspective, science (B) looks exactly like any set of claims about reality.
Engineers seem very prone to this (as we see in this thread, and from the astonishing number of creationist engineers out there). They live in a world in which the fundamentals are found in reference books, and only the application of those fundamentals are important, not their origins.
It's easy to see how someone who is used to relying on what it says in the manual, the book, or the regulations, would see a close similarity between science (B) and religion, and would barely consider science (A) when asserting that science (B, though they don't know or care, so they assume, incorrectly, also A) is of the same general form as religion.
Schools don't help; They teach everything the way that religion is taught (schools began as religious institutions) - The teacher is an authority and not to be challenged; The right answer is the one in the book; And as long as you
remember the rules, you need not
understand them.
Science (A) is nothing at all like any religion. And science (B) is only superficially like religion, and that's because religion defined the way that it is taught, and because both religion and science (B) give people comforting structure and rules to follow, that require far less effort than science (A).
Engineers often
do trust science (B), whereas scientists have
not trusting
anything - including science (B) - as a fundamental element of science (A).
