3 Hours: 3 Parts: A: Historical (1 question out of 4), B: Modern Concepts (2 questions out of 5), C: Problems (2 out of 5): each answer worth 20%

A: Historical (answer 1 of the following 4 available questions. Your answer should take the form of a short essay of about 400-600 words).

For this part, you should expect questions on cosmological measurements, the Aristotelian and Copernican systems, the opposing positions of Newton, Leibniz and Mach on the nature of space and time, and historical developments concerning the discovery of the expansion of the universe

B: Modern Concepts (answer any 2 of the following 5 available questions. Answer in point form, using diagrams, graphs, etc. to make your points).

For this part, you should understand the twin paradox, space and time dilation, the arguments for spacetime being curved, Mach's Principle and the Equivalence Principle, differences between the predictions of Newtonian and Einsteinian gravitational theory, observational tests for the Big Bang theory, Inflationary Cosmology, and the evidence for Black Holes and their evaporation.

C: Problems (answer any 2 of the 6 available problems).

For this part, you should expect problems involving conceptual understanding and simple algebra concerning, for instance, Special Relativity, tests for the Equivalence Principle, Black Holes, Cosmological Redshift, Dark Energy and Vacuum Energy.

CRIB SHEET: you are allowed one 216 mm x 279 mm (8.5" x 11") crib sheet with at least 1 blank side.

Depending on what you can remember, you might want to include such items as Newton's Law of Gravity, the Friedmann equation, formulas concerning scale factors, the Schwartzschild radius, and black body radiation, and the current temperature of the Microwave Background Radiation. You will be given values such as G, the Hubble constant, and Planck's constant.
