Episode notes
Quantum Physics Basics
- Quantum physics operates probabilistically, not deterministically.
- The observer effect means observing a particle changes its state.
Observer Effect Explained
- Shining light on a particle to observe it alters its location.
- This is due to the light's energy impacting the particle, not consciousness.
Rocket Propulsion and Energy
- Current rockets use exothermic chemical reactions for propulsion.
- We are still reliant on chemical energy for propulsion, similar to batteries.
