The Cosmological Constant
Future Universe with Lambda

Basic Idea: If the universe expands forever, eventually we will enter dark ages where there hardly any radiation and most matter has decayed. With a cosmological constant we will have an era of inflation as well, before much of this happens.


  • Future of the universe with no Lambda
    • eras: primordial, stelliferous, degenerate, black hole, dark
  • Future with Lambda
    • Scale for where lambda will have an effect
    • When will we stop seeing things? which things
  • What if not actually lambda but just quintessence?
  • Unpredictability of what will happen given possible measurements
