Reality is messy and error is never zero

"True" and "false" are well defined in mathamatics and logic and devine revelation. Otherwise "true" and "false" are problematic concepts. Trustworthy science is not mathematics. Trustworthy science can not give true or false. Trustworthy science is messy. If you seek truth, then trust only mathematics and logic and devine revelation.

Reality is messy. Trustworthy science is about this messy reality. Trustworthy science gives trustworthy evidence about messy reality. The goal of trustworthy science is to ever improve measurements and calculations to make this evidence about messy reality ever more trustworthy. If you seek trustworthy evidence about messy reality, then trust science.

Zero is a fundamental concept in mathematics. This zero of mathematics is not very small. It is zero — the absence of everything. Trustworthy science is not mathematics. The zero of mathematics has no role in trustworthy science. Great care must be taken to avoid importing the zero of mathematics into trustworthy science.

Trustwrthy science is about messy reality. In messy reality the absence of everything does not occur. Momentum of a body is conserved when external forces are zero, but external forces are never zero. Energy is conserved in a closed system, but there are no closed systems. Calculations — using conservation of momentum and conservation of energy, for example — can give results with extremely small error, but not zero error.

All calculations in trustworthy science have some error. That error can be extremely small, but can not be zero. All measurements in trustworthy science have some error. That error can be extremely small, but can not be zero.

Trustworthy science gives trustworthy evidence about messy reality. The goal of Trustworthy science is to ever reduce errors in measurements and calculations to make trustworthy evidence about messy reality ever more trustworthy. If you seek trustworthy evidence about messy reality, then trust science.

In messy reality errors are never zero. This means that in messy reality uncertainity is never zero. This means that in messy reality risk is never zero.

If you seek zero risk, if you seek zero uncertainity, if you seek zero error, then do not look for these zeros in trustworthy science.
