Abstraction In Theory - Laws Of Physical Transactions GangulySubhajit 2012 <p>Considering transportĀ  or tendency of transport of physical entities from an initial to a final point,we come to a similar basis of understanding of various physical phenomena.The trajectory-behaviour of such transport represents the effect orĀ  field of influence.This way,we may explain cluster-formation in the universe,an expanding universe,etc.This may also lead to a similar basis for understanding the four non-contact forces of nature.Also,for different ranges of acceleration in the field formed in spacetime,we have different properties of matter interacting.This may explain the difference in ranges of the various forces.</p>
