Space and Time in the Fundamentals of General Relativity

Authors: Valdir Monteiro dos Santos Godoi
Comments: 11 Pages.

We examined the variations of space and time that occur under the influence of a gravitational field produced by a mass M, following the Foundations of General Relativity, by Einstein (1916). We conclude that when we use the conventional units for the speed of light resulting values are very different from those obtained by adopting the speed of light equal to 1, and that certainly could not be in agreement with the experimental values. The shortening of the rulers (scales) and slowness of the clocks would be much higher, because would no longer divided by the square of the speed of light.

A Metaphorical Chart of Our Mathematical Ontology

Authors: Philip Gibbs
Comments: 10 Pages. FQXi essay contest entry 2015

This is my vision of the relationship between mathematics and physics based on my observations on the nature of physical laws and mathematical structures. I use mainstream ideas from quantum gravity such as string theory, holography, the landscape and loop quantum gravity as a base for my reasoning. In addition I bring together more speculative ideas such as the Mathematical Universe Hypothesis, multiple quantisation, universality, iterated integration maps and complete symmetry. In my view these clues come together into a consistent whole where a structure from higher category theory is the central piece from which all else stems. The future of fundamental physics is going to be much more challenging than the past on both the experimental and theoretical sides and these meta-physical structures need to be understood to guide us towards the more specific physical laws which rule our universe. On a more philosophical level they can provide an explanation for why we exist and why the laws of physics are so steeped in mathematical abstraction.
