If time travelers had a meeting place where it was written on a blackboard "See you here yesterday," it would create a paradoxical situation because it implies that time travelers can travel back to a time before the meeting took place, leading to a contradiction.
Suppose a time traveler saw the message and traveled back in time to meet their past self, who then wrote the message on the blackboard. In that case, a paradox would arise since the original message would not have had an origin, and it would be impossible to determine where it came from.
This scenario creates a classic "bootstrap paradox," where an object or information is created without any apparent origin or cause, making it impossible to determine how it came into existence.
Therefore, while the phrase "See you here yesterday" may be catchy, it creates a paradox that cannot be practically executed without violating the laws of causality.
Welcome time travelers Midjourney, see you here yesterday.
The bootstrap paradox is a hypothetical situation in which an object, information, or an idea is said to exist without having been created, and the origin of it becomes a paradox. It is named after the phrase "pulling oneself up by one's bootstraps," which refers to a physically impossible task. In essence, the paradox arises when the cause and effect of an event are indistinguishable from each other, and it becomes difficult to determine which one came first. For example, imagine a musician who hears a song in a dream and then wakes up and writes it down, only to find that the song already exists in the world, and no one knows who wrote it. The paradox arises because the musician seemingly created the song out of nowhere, but in reality, they were merely a conduit for it to enter the world.
The laws of causality, also known as cause and effect, are fundamental principles in philosophy and science that state that every event has a cause and effect relationship. The cause comes before the effect, and it is the reason that the effect happens. In other words, an event cannot occur without a cause, and the cause must always precede the effect in time. The laws of causality are crucial in understanding the physical world and are the basis of scientific inquiry. They allow us to make predictions about how things will behave and to understand why they behave the way they do. The bootstrap paradox challenges the laws of causality because it appears to violate the idea that every effect has a cause, and that cause comes before the effect.
