## About the Nature of Time

**Authors:** Matti Pitkänen

The identification of the experienced time te and geometric time tg involves well-known problems.
Physicist is troubled by the reversibility of tg contra irreversibility of te, by the con
ict between
determinism of Schrödinger equation and the non-determinism of state function reduction, and by
the poorly understood the origin of the arrow of tg. In biology the second law of thermodynamics
might be violated in its standard form for short time intervals. Neuroscientist knows that the moment
of sensory experience has a finite duration, does not understand what memories really are, and is
bothered by the Libet's puzzling finding that neural activity seems to precede conscious decision.
These problems are discussed in the framework of Topological Geometrodynamics (TGD) and TGD
inspired theory of consciousness constructed as a generalization of quantum measurement theory. In
TGD space-times are regarded as 4-dimensional surfaces of 8-dimensional space-time H = M4xCP2
and obey classical field equations. The basic notions of consciousness theory are quantum jump
and self. Subjective time is identified as a sequence of quantum jumps. Self has as a geometric
correlate a fixed volume of H- "causal diamond"-defining the perceptive field of self. Quantum
states are regarded as quantum superpositions of space-time surfaces of H and by quantum classical
correspondence assumed to shift towards the geometric past of H quantum jump by quantum jump.
This creates the illusion that perceiver moves to the direction of the geometric future. Self is curious
about the geometric future and induces the shift bringing it to its perceptive field. Macroscopic
quantum coherence and the identification of space-times as surfaces in H play a crucial role in this
picture allowing to understand also other problematic aspects in the relationship between experienced
and geometric time.
