Abstract

The asymmetry of nature under a ‘reversal of time’ (that is, a reversal of motion and change) appears only too obvious to us, as it deeply affects our own form of existence. If physics is to justify the hypothesis that its laws control everything that happens in nature, it should be able to explain or describe this fundamental asymmetry which defines what may be called a direction in time or even — as will have to be explained — a direction of time. Surprisingly, the very laws of nature are in pronounced contrast to this fundamental asymmetry.
