This video explores how time works in physics, examining theories like presentism, the block universe, and the growing block universe to understand whether the past, present, and future all coexist.
From the video
Answers: Does the future already exist and how does time work in physics?
- Physics of time
- Theory of relativity
- Block universe theory
- Presentism
- Growing block universe
- Quantum mechanics and time
What it concludes
- According to the theory of relativity, space and time are not separated, but form connected spacetime where different observers experience different 'now' moments.
- Presentism, the block universe, and the growing block universe are three different models used by physicists to describe how time works, though no consensus exists on which one is entirely correct.
- Quantum particles are intrinsically random and cannot be predicted, which means the future cannot be strictly set in stone if quantum uncertainty is fundamental.
