The main evidence for the theory of no big bang is the observation of cosmic microwave background radiation, which is believed to be leftover radiation from the initial expansion of the universe. However, this radiation can also be explained by other theories such as the steady-state theory.
The theory of no beginning and no end challenges the traditional theory of the universe by proposing that the universe has always existed and will continue to exist indefinitely, rather than having a specific starting point and eventual end. This challenges the idea of a singular moment of creation and the concept of an ultimate fate for the universe.
The theory of no beginning and no end suggests that time is cyclical and has no ultimate beginning or end. This challenges the traditional linear understanding of time and suggests that the concept of time may be more complex than we previously thought.
The theory of no beginning and no end suggests that the universe will not experience a "Big Crunch," where it collapses back in on itself. Instead, it proposes that the universe will continue to expand and contract in a cyclical manner without ever reaching a point of complete collapse.
The theory of no beginning and no end challenges our traditional understanding of the origins of the universe and opens up the possibility for alternative explanations. It also raises questions about the concept of a singular moment of creation and the role of a higher power in the creation of the universe.
