The mandela effect
title: “The Order of Time-Carlo Rovelli” layout: note date: 28-08-2022 permalink: /order-of-time-cr tags: [BookNotes] last_modified_at: 2023-12-08 12:09 from a physics point of view. I read it as I’m getting older and wondered what the hell time is anyway. I’m not sure I found out.
Key Ideas
Time is Relative
- It runs at different speeds at different places. Up a mountain, it is slower. In space, it is slower still. It is also affected by speed. The faster something moves the less time passes.
- Mass slows time around it.
- Sun and earth fall around each other due to time.
- Gravity is time
- Speed slows down time.
The only Law of Physics that is Directional is Heat.
- Always goes hot to cold, never the other way round.
- Seeking equilibrium. Entropy.
- Heat is the only distinction between past and future.
Entropy is Relative
- No distinction between cause and effect.
- No shared present, multiple overlapping present times.
- can overlap and circle back
Time is a Field, Acted on by other Forces.
- Can stretch and change.
- Time is granular, made up of Planck seconds- smallest divisible unit.
- Time exists in a superposition. Unsure of how it exists until it interacts with the world.
- Therefore the past, present and the future are indeterminate

The Actual-Inua Ellams
You would expect series of poems, all starting with “fuck” to be furious. Of course, there is rage in these...
