| Video Discription | The grandfather paradox is considered the biggest, most popular objection to the logical possibility of backwards time travel. It characterizes a hypothetical situation in which a time traveller goes to their past and ends up causing an event (like, the killing of their grandfather) which makes travelling to the past and altering it impossible. What this means is that if you go back in time and kill your grandfather, you don’t exist, which means that your grandfather cannot be killed. As you can see, there are two realities occurring in parallel here. The grandfather paradox is also a key plot element in the famous Hollywood movie Tenet (released in 2020), directed by Christopher Nolan. Although all this talk about time travel and the grandfather paradox is obviously purely hypothetical, there is evidence of two realities occurring in parallel at the same time. This is a phenomenon in the quantum world which is known as superposition.
