SUMMARY

The 1994 debate between Stephen W. Hawking and Roger Penrose significantly influenced modern physics, particularly in the realms of quantum mechanics and relativity. Their discussions, later published in "The Nature of Space and Time" (1996), have prompted ongoing inquiries into the evolution of their theories. Recent insights indicate that Penrose has largely shifted focus away from twistor theory, while Hawking has revised his stance on black hole information. Current mainstream physicists continue to explore these foundational concepts, reflecting the debate's lasting impact.

PREREQUISITES
  • Understanding of quantum mechanics principles

In 1994, Stephen W. Hawking and Roger Penrose gave a series of lectures which culminated in a debate about how universal and applicable the theories of quantum mechanics and relativity are. (Their lectures and debate were published in book form in 1996 under the title The Nature of Space and Time, Hawking and Penrose, Princeton Univ. Press.)

Since that was more than a decade ago, I was wondering what advances or discoveries were made since then that might have changed their views or positions.

What now is the current thinking of mainstream physicists who work in these areas?

Have either Hawking or Penrose changed their minds? I do believe, for example, that Penrose has more or less stopped research on his twistor theory.

Since then, Hawking has changed his mind about information and black holes.

This year, Hawking turns 65 amd Penrose 76.
