Issues in Philosophy The Philosophy of String Theory

The Philosophy of String Theory

In this week’s talk from the Institute of Art and Ideas, we look to unravel the secrets of the universe.

Over 40 years have passed since string theory was first developed: what questions have been answered? Can we ever find solutions to these profound issues and usher in a new age of science?

Philosopher James Ladyman examines one of our strangest endeavours.

  1. “The promise of string theory is the culmination of this programme of unification.” I say that Milgrom is the Kepler of contemporary cosmology — and the programme of unification needs to take heed of MOND. Are there MOND-chameleon particles that have variable effective mass depending upon nearby gravitational acceleration?
    According to Wolfram Alpha:
    ((Planck length)/(Planck time)^2) / (1.2 * 10^-10 m/sec^2) = 4.634 * 10^61 (Here the denominator is the approximate MOND acceleration constant.)
    Can MOND-chameleon particles somehow be used to explain the vacuum catastrophe?
    Google “vacuum catastrophe”, “mcgaugh milgrom”, “kroupa milgrom”, and “witten milgrom”.

  2. The big bang has happened numerous times in the past and we are not the only universe in space,gravity rules to create another big bang,a continuous cycle of rebirth
