No big bang, no beginning, and no end?

In summary, the article discusses a model that proposes the universe has no beginning, end, or big bang. The model suggests that the speed of light and gravitational constant may not be constant, but this cannot be tested and may introduce new problems. The model would be more compelling if it could predict the power spectrum of the cosmic microwave background.

Interesting, but, speculative. It admits to no apparent way to test the idea that the speed of light and the gravitational constant are not invariant. Having them vary in such a way as to be undetectable obviously invokes just another fine tuning problem to replace the ones we already face in the current model. I do not view that as progress.

A model like this doesn't get interesting to me until it can predict the power spectrum of the CMB.
 

FAQ: No big bang, no beginning, and no end?

1. What is the evidence for the theory of no big bang?

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.

2. How does the theory of no beginning and no end challenge traditional theories of the universe?

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.

3. What implications does this theory have for our understanding of time?

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.

4. How does this theory address the concept of the "Big Crunch"?

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.

5. What are the potential implications of this theory for our understanding of the origins of the universe?

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.
