1.) does a stationary charge in a gravitational field radiate (as per the principle of equivalence)? 2.) why have we been advancing from seemingly less intelligent species to a more intelligent one? what is its physical significance (besides intelligence corresponding to complexity) ? why do we know more now ,than anytime in the past ,and less than anytime in the future? 3.) what is a law ? a complete law must be self consistent ;as such it should explain its own existence.........so the fundamental set of the laws of nature must be such that it explains its own existence ,and the existence of everything it explains.........such a law is but restricted by the Godel's incompleteness theorem.............plz comment..!
