Document Summary

Describe how various models of the universe appear on the hubble diagram. Describes the first fractions of the second of our universe when the distances of the order of 10^-33 cm were viewed in 10 dimensions. Big crunch would lead to a new big bang. Superstrings can explain why 3 out of 10 dimensions can expand. Superstrings can explain how quantum fluctuations in a previous universe can expand. M theory offers a new look at our universe a brane member of the multiverse. A 5th macro-dimension separates various universes, which are 4 dimensional surfaces on 5-dimensional bubbles. Only the gravitational force can act in the 5th macro-dimension. Big bang in the m theory is a collision between two parallel universes. Big bang does not require infinite temperature and density. Interbrane gravitational force draws branes together amplifying quantum wrinkles of the dark energy when it is 100% of the content of the universe.
