The Grandfather Paradox: Altering timelines
Art by: Sofia Ayuso
What happens if someone time travels to the past and kills their grandfather before he had children?
In linear timelines that fix "the present" as a mid-point between past & future, the killer would cease to exist, therefore creating a paradox.
Other theories on time travel can potentially work around this paradox:
- Relativity links time & space so the faster you travel the slower you experience time (Einstein) .
- Quantum - every time one state, or outcome, is observed, there is another "world" in which a different quantum outcome becomes reality. (Many-Worlds Theory).
