SUMMARY

This discussion centers on the misconceptions surrounding quantum entanglement and its implications for communication across time and space. It is established that entangled particles do not enable faster-than-light communication or the ability to send signals back in time. The conversation clarifies that both entangled and unentangled particles travel through time and space at the same speed, adhering to the principles of relativity. Therefore, building a device to communicate with past or future selves using quantum entanglement is not feasible.

PREREQUISITES
  • Understanding of quantum entanglement
  • Familiarity with the principles of relativity
  • Basic knowledge of particle physics
  • Awareness of the limitations of faster-than-light communication
NEXT STEPS
  • Research the principles of quantum entanglement in detail
  • Explore the implications of Einstein's theory of relativity on communication
  • Study the limitations of quantum mechanics regarding time travel
  • Investigate current advancements in quantum communication technologies
USEFUL FOR

Physicists, students of quantum mechanics, and anyone interested in the theoretical aspects of time travel and communication technologies.

I have a question about quantum entanglement. If quantum entanglement can cause particles to travel through time and space does that mean we can use them to communicate with the future or past. Say I build a device on Monday that recives and transmits such particles would I be able talk to my self that exists in Tuesday assuming I still had the device, and when it came Tuesday could I talk to my past self on Monday and so on. Also would I be able to communicate across space instantaneously with such a device.

There is no connection between what you are asking and quantum entanglement.
 
Entangled particles travel through time and space the same way unentangled. Neither can exceed the speed of light and neither can send a signal back in time.
