This is the only post, I think, in which I touch on the SHA256 algorithm.
You are right about science. No, you are mostly right. There are things in modern science that are evidently wrong but are accepted because we can not think of a better alternative or we just haven't found a better alternative or there is a better alternative but we chose to ignore it. For example, do you know how we have concluded that the Earth's inner core is of iron and nickel while there is really no way this can be verified.
- the Earth has a magnetic field and iron and nickel can be magnetized. Which is a false argument since any electric conducting medium can be magnetized.
- Iron and Nickel are elements most commonly found in meteorites. This is actually a reason why people have decided that the Earth's core must be made up of these elements, but I completely fail to see the connection.
Thus there are many generally accepted "facts" which have an extremely thin proof.
