Entanglement at cosmic distances possible?

In summary, the conversation discussed the possibility of entanglement at cosmic distances and whether it could be used to send messages between alien civilizations. However, it was concluded that entanglement does not carry information and cannot be used for communication.

entanglement at cosmic distances possible??

Warning, crazy question from uneducated human :-) Patience required.

Ok, so say there is an Alien civilization far away, and they and we both 'see' a event, say a supernova.

Is there a way that the photons WE recieve, and the photons THEY receive would be in any way entangled and thus allow some kind of message to be sent between us?

How about photons emitted from matter falling into a black hole?

IF the photons were entangled how could we 'send' a message by collapsing the wave function associated with those photons? Say send 3.14159 or some such?

You were warned, crazy questions from ignorant armchair physics nuts

Entanglement does not carry information and cannot be used to send messages. Period.
 

1. What is entanglement at cosmic distances?

Entanglement at cosmic distances refers to the phenomenon in quantum mechanics where particles become intertwined with each other, even when they are separated by vast distances. This means that the state of one particle can affect the state of the other, regardless of the physical distance between them.

2. How is entanglement at cosmic distances possible?

Entanglement at cosmic distances is made possible through the process of quantum entanglement, where two particles become connected and act as one system. This connection allows for instantaneous communication between the particles, regardless of the distance between them.

3. Can entanglement at cosmic distances be observed?

Currently, entanglement at cosmic distances has not been directly observed. However, there have been experiments that have demonstrated entanglement between two particles separated by large distances, providing evidence for the phenomenon.

4. What are the potential applications of entanglement at cosmic distances?

Entanglement at cosmic distances has potential applications in the fields of communication and computing. It could potentially allow for secure communication over long distances and enable the development of quantum computers that can solve complex problems more efficiently than classical computers.

5. Are there any limitations to entanglement at cosmic distances?

Although entanglement at cosmic distances shows promise for various applications, there are still limitations and challenges that need to be overcome. These include maintaining the entanglement over long distances and preventing interference from the environment that could disrupt the entangled state.
