Kx000: Of course knowledge can be subjective. Then why bothering with reference frames in physics? Physical laws and measurements depend largely on who is the reference frame (e.g. relativity of speed, time intervals etc). Don’t confuse with the term knowledge that we use in everyday life (e.g. learning) that is a human made definition. I use it in a more scientific way. Fraggle Rocker: How possible is the spontaneous creation of a system that always accumulates decreases in entropy by messing up the environment, in terms of energy levels? Creationists: How can one directly fit god into pure mathematical or physical equations? This was attempted many times in the history of mankind and always creationists were proven wrong (with sometimes disastrous consequences).
