The answer is "Daniel's theory cannot be disproven."
A scientific theory is an all around substantiated clarification of some part of the natural world, in view of an assortment of actualities that have been over and again affirmed through perception and examination. Such certainty upheld hypotheses are not "surmises" but rather dependable records of this present reality.
On the off chance that its absolutely impossible a theory can be disproved at that point it is extremely unlikely the theory (or model) can be changed/made strides. This is the key refinement amongst philosophy and science.
