Final answer:
Ethical principles and personal beliefs are examples of things that cannot be proven by the scientific method as they are subjective and not open to empirical testing.
Step-by-step explanation:
What cannot be proven by the scientific method, besides a higher power such as God, include ethical principles and personal beliefs. The scientific method is effective at testing hypotheses through observation and experimentation, which applies to observable phenomena and can provide support for or against particular theories. However, areas such as ethical principles and personal beliefs are subjective and not testable through this method, as they fall outside the realm of empirical, measurable evidence and often relate to individual or cultural perspectives which cannot be universally quantified or observed.
For example, the statement "Killing is wrong" is an ethical principle that cannot be proven or disproven with scientific testing, as it is a moral stance. Similarly, personal beliefs such as "I believe in luck" cannot be empirically validated using the scientific method; beliefs are individual, based on personal experiences, and therefore are not subject to external testing for universal truth.
