Why is it possible that an object can be found in the same place in different times but can not be found at the same time in different places?
JesseM said:Yes, if you could have a faster-than-light particle with a spacelike worldline, then according to the definition of "same time" used by inertial frames in relativity, there would be at least some frames where the particle would be at different places at the same time.
Classically we have no difficulty in identifying a given timelike particle now and earlier as the same particle provided the worldline is continuous. I would think that we would similarly have no conceptual difficulty in identifying a given spacelike particle here and there as the same particle provided the worldline is continuous.Mueiz said:This means that if you could have a faster-than-light particle then even the existence of a particle is relative because diffirent place at the same time means another particle

The "Space-Time Puzzle" is a concept in physics that deals with the idea of objects existing in two places at once. This goes against our understanding of space and time, which suggests that an object can only exist in one place at a given moment.
According to our current understanding of space and time, objects cannot be in two places at once because they are bound by the laws of causality. This means that an object can only be in one place at a given moment because it is affected by the events and forces around it.
The "Space-Time Puzzle" challenges our understanding of the fundamental laws of physics and raises questions about the nature of reality. It has been a subject of much debate and research among scientists and philosophers.
At this point, there is no definitive solution to the "Space-Time Puzzle". However, many theories and hypotheses have been proposed to try and explain this phenomenon. It is an ongoing area of research and discovery in the field of physics.
The "Space-Time Puzzle" is closely related to other concepts in physics, such as quantum mechanics and general relativity. It also ties in with the concept of superposition, where an object can exist in multiple states at the same time. Understanding the "Space-Time Puzzle" could potentially lead to a deeper understanding of these other concepts.
