Cosmology baumann solutions

What happened when the universe cooled below 3000 K?
380,000 years after the Big Bang - The temperature of the universe had cooled to about 3000 K.
Electrons began to combine with hydrogen and helium nuclei.
High energy photons from this period rushed outwards..
Vacuum energy is thought to be the main ingredient in the “cosmological constant,” a mathematical term in the equations of general relativity.
The enormous discrepancy between the predicted amount of vacuum energy and the measured amount is often called the cosmological constant problem.

Jan 1, 2021This course is about 13.8 billion years of cosmic evolution: At early times, the universe was hot and dense. Interactions between particles

How did quantum cosmologists solve the graceful exit problem?

The dynamics of this murky initial period were divined by quantum cosmologists", a secretive sect which contemplated deep metaphysical notions such as:

he wavefunction of the universe". potential; they are pure polynomials or have an extended at region, respectively.
The graceful exit problem is solved by the theory of reheating.

What is a good introduction to cosmology?

Ryden, Introduction to Cosmology.
A well-written undergraduate-level introduction to cosmol- ogy, assuming very little background; a bit vague, but good for a rst pass to get intuition.
Mukhanov, Physical Foundations of Cosmology.
An introduction to cosmology and astropar- ticle physics with a distinctly Russian avor.
