    How does a wave function collapse?

    In this connection, I want to know what happens when the particle is not being observed although light is shone at it the same way as if it were being observed. Does the wave function collapse take place in such a case?

    How does a wave function collapse?

    That is allright. But IMO that our thinking ability and conciousness is equally as mysterious? We don't know for sure what the heck consciouness is?

    Is wave-function collapse a REAL incident

    What happens when the experiment isn't being observed, although light is shone on the particles? Does the collapse take place in absence of human observers? And thanks for that suggestion, Bcrowell

    Is wave-function collapse a REAL incident

    Dear Dr. Chinese, I also want to know if there any precedence where the “wave-function collapse” has occurred even in the ABSENCE of an observer (simply because light was shown on the particle, although NO ONE WAS PEEPING)?

    Is wave-function collapse a REAL incident

    Scientists/Physicists/Truth-seekers, I am looking for answers to some questions, which I confess are issues of gobbledygook debates. But this time I want serious and simple answers. So no debates please. My questions are as under:- Is wave-function collapse a REAL incident or just a...

    Is retro-causality a science fact?

    The "delayed choice" double-slit experiment seem to suggest that a measurement done, in the present, is able to change the past (history) of a particle. Does it imply that a cause arising in the future can change the past? If not what else does it mean? In our common sense view of causality...

    Cause and effect

    In this context I would like to point out that the "delayed choice" double-slit experiment seem to suggest that a measurement done, in the present, is able to change the past (history) of a particle. So, evidently a cause arising in the future can change the past. In our common sense view of...

    What does Quantum entanglement tell about Causality?

    If that is true, it will have immense implications on our understanding and way of reasoning. If there is no causality, it would mean that you could no longer say that the effect is dependent on the cause. It could just be the other way round, i.e. the cause depends on the effect. That would...

    What does Quantum entanglement tell about Causality?

    Entangled particles seem to have 'causal impact' on each other 'instantly' violating the allowed speed-limit of causal influence i.e. 'c'. When one of the entangled particles is measured it has an impact on the other instantly. These two events (i.e. 1. the measurement of the first particle and...

    How does QFT address the problem of Locality in Quantum Entanglement?

    What you said about information transfer is allright. But what about the "causal influence". I mean, when one of the entangled particles is measured, it has an "effect" on the other particle (instantly). The measurement of the first particle, "causes" this impact. So the two events (1...

    How does QFT address the problem of Locality in Quantum Entanglement?

    Quantum Entanglement allows spatially separated entangled particles to have impact on each other instantly (overcoming the allowed speed-limit of causal influence which is 'c'). How does Quantum Field Theory address this problem (protecting causality and chronology)?

    If gravity is not a force, why does it need to be carried by Gravitons?

    According to General Relativity, gravity is not a force. It arises from the curvature of space-time due to presence of matter. Matter curves space-time in a way that the paths of things appear to be bent giving rise to th effects of gravitiation. But if gravity is not a force, why do we need...

    How can something have both a constant speed and a precise location?

    In QM surely the question about position is meaningless. But then, why do they say that QM and Relativity are incompatible? Relativity shows that things travelling at the velocity of light must have the same velocity for all reference frames. QM suggests that they do not have a precise...
