3.9.1 The Problem of Causality
As we have seen in section 6.3 above, the Big Bang is a space-time singularity, which means that time started with the Big Bang, and not the opposite. The question is therefore: what is the cause for the Big Bang?
Some physicists and philosophers argue that nothing can’t exist, and non-existence have never been an option. Leibniz, however, asked the question: “Why is there something rather than nothing?”, and he concluded that the sufficient reason is found in a substance which is a necessary being bearing the reason for its existence within itself. This philosophical question will be discussed in chapter IV, but according to the Duality of Time, causality itself is not a fundamental principle anymore, but a result of the perpetual creation in the inner levels of time, as we shall discuss at the end of chapter VII.
