And, it’s that
time of the year when one can get back into the business of writing, doing physics
and thinking beyond the curbs and bliss of the daily grind. This means hard
thinking; my hobby-horse, the nature of time. That illusion or a trick of mind
that presents us with a persuasive, ever meandering, passage of time. Here I’m talking in
the tradition of Plato, we find time, mathematics and all else on a higher
plane that our mind sees into, by a process not unlike sense perception. And I
suppose, the inter-play between time and space, the time-space manifold, Riemannian
geometry is/was there for Einstein to see.
One of Gödel’s less
well-known papers is a 1949 article called, “A Remark on the Relationship
Between Relativity Theory and Idealistic Philosophy.” In this paper, Gödel
attempts to show that the passage of time is indeed an illusion. The past,
present and future of the universe are just different regions of a single vast
space-time. Time is part of space-time, but space-time is a higher reality
existing outside of time.
For many, including Gödel,
mathematics, even the mathematics of the infinite, was an essentially empirical
science. But when we begin to talk about infinite numbers that the trouble
really begins. Cantor’s Continuum Problem is undecidable on the basis of our
present-day theories of mathematics. For a Platonist like Gödel, this means
only that we have not yet “looked” at the continuum in a hard enough way.
