nice timetable. Keep it organic....if it needs to be altered....work on it.
May I suggest you investigate the philosophy of science. I know it sounds a bit weird....but its great to get you thinking about what can be known, what
is known and how to interpret data.
Blokes like Karl Popper and David Hume paved the way. Karl went on to
falsifiability
Definition -
Falsifiability or refutability of an assertion, hypothesis or theory is the logical possibility that it can be contradicted by an observation or the outcome of a physical experiment. That something is "falsifiable" does not mean it is false; rather, that if it is false, then some observation or experiment will produce a reproducible result that is in conflict with it.
For example, the assertion that "all swans are white" is falsifiable, because it is logically possible that a swan can be found which is not white. Not all statements that are falsifiable in principle are falsifiable in practice.
Right now we feel that gravity is present in the entire universe....we can't quite be 100% sure of this though since we have not observed the entire universe.
