Abstract

In this essay I will discuss the relation between information and spacetime. First I demonstrate that because of diffeomorphism invariance a smooth spacetime contains only a discrete amount of information. Then I directly identify the spacetime as carrier of the Bit, and derive the matter (as It) from the spacetime to get a direct identification of Bit and It. But the picture is stationary up to now. Adding the dynamics is identical to introducing a time coordinate. Next I show that there are two ways to introduce time, the global time leading to quantum objects or the local time leading to a branched structure for the future (tree of the Casson handle). This model would have a tremendous impact on the measurement process. I discuss a model for the measurement of a quantum object with an explicit state reduction (collapse of the wave function) caused by gravitational interaction. Finally I discuss also quantum fluctuations on geometrical grounds. Dedicated to the memory of C.F. von Weizsäcker.

Notes

  1. 1.

    Here I remark a mathematical fact which is not easy to see: every homology 3-sphere is contained in the wild \(S^{3}\).

  2. 2.

    This fact is folklore in Khovanov homology to describe the concordance class of a knot.
