The Light Cone: an illuminating introduction to relativity
by Rob Salgado
Publisher: Syracuse University 2005
Number of pages: 250
These documents comprise an elementary introduction to the Theory of Relativity. The intended audience is a class of nonscience undergraduates. Our plan is to follow a pseudo-historical development of how we came to understand "Spacetime", the spacetime of General Relativity.

Aimed at people who do not know enough physics to understand what Einstein did and why it was so important. The course presents just enough of Einstein's physics to give students an independent sense of what he achieved and what he did not achieve.

Notes from the lectures on Quantum Cosmology and Baby Universes. The lectures covered quantum mechanics for closed systems, generalized quantum mechanics, time in quantum mechanics, the quantum mechanics spacetime, and practical quantum cosmology.

Assuming no prior knowledge by the reader, the book raises specific, hitherto overlooked questions about how time works, such as how and why anyone can be made to be, at the very same instant, simultaneous with events that are actually days apart.

The book offers an alternative to Einstein's special theory of relativity, with the main purpose of developing a form of relativity, which can be combined with quantum mechanics and thus can open to a unified field theory.
