Reflections on the nature and direction of time

Explore the concept of time and its relationship with reality, from its origins in the universe to its existence as an emergent property. Delve into theories such as the Big Crunch and the Big Bang, background microwave radiation, inflation, the multiverse, and the String Theory Landscape. Reflect on the arrow of time and the thermodynamic arrow of time, questioning whether time is an illusion and if it can be understood as a succession of frames. Contemplate the possibility of more than one-dimensional time and the Many-Worlds Interpretation of Quantum Mechanics. Engage in the intriguing discussion of whether our reality is a simulation.

  1. Reflections on the nature and direction of time

  2. Talk structure • Caveat • 10 minutes reflections on reality • 12 minutes reflections on time • 8 minutes concluding reflections

  3. Nature of reality We need to reflect on what our reality is • Whether time was born with this universe? • Or is time embedded in the fabric of “reality”? • Or is it emergent from more fundamental stuff? • And in what direction does it move?

  4. Big Crunch to Big Bang

  5. Background microwave radiation

  6. Inflation

  7. Big Bounce

  8. Multiverse?

  9. The String Theory Landscape

  10. The Bulk

  11. Time – “..a big ball of wibbly-wobbly, timey-wimey stuff” Scientists insist that the most successful theories in physics prove that time does not exist

  12. Time is not absolute

  13. The arrow of time

  14. Thermodynamic Arrow of Time

  15. Is the Arrow of Time an Illusion?

  16. Time a succession of frames?

  17. The three theories

  18. More than one dimensional time

  19. Many-Worlds Interpretation of Quantum Mechanics

  20. Are we living in a simulation?
