Abstract
In this essay, I research the concept of B-time and Becoming with three parts. First, I introduce McTaggart's paradox to show the context of philosophy of time in modern time and to illustrate the standpoint and problems of A theory. Second, I would explain the solutions from B theorist and following problems and further explain how new B theorist deal with these problems. Finally, through the ontological analysis of B time and through dialectics of varied concept of Becoming of A theory, I construct the Becoming in B-time, which I call “B-becoming”.
