The book offers an alternative to Einstein's special theory of relativity, with the main purpose of developing a form of relativity, which (in contrast to Einstein's relativity) can be combined with quantum mechanics and thus can open to a unified field theory. We refer to the alternative as many-minds relativity, requiring different observers to agree on different information to different precision, asking for high precision only on essential information.

This book goes back to the work of the philosophers and astronomers of two thousand years ago; and it extends to that of Einstein, whose work laid the foundations for our present-day ideas about the nature of space itself.

Which geometries on a smooth manifold can serve as a spacetime structure? This question is comprehensively addressed from first principles, exploring the kinematics and gravitational dynamics of all tensorial geometries on a smooth manifold.

We introduce a relativistic splitting structure as a means to map equations of electromagnetism from curved four-dimensional space-time to 3-dimensional observer's space. We focus on mathematical structures that are motivated by the physical theory.
