Quantum entanglement and Two slit experiment

Click For Summary
Quantum entanglement is believed to self-decohere at the macro level, making it challenging to maintain entangled states outside closed systems. While there is no conclusive proof that consciousness causes wavefunction collapse, it is generally not considered a necessary factor in quantum mechanics. Observations can collapse wavefunctions through interactions with any particle or sensor, not just conscious observers. The nature of photons is complex, exhibiting both wave-like and particle-like properties, which is supported by experimental evidence. Overall, the relationship between consciousness and quantum mechanics remains a topic of debate without definitive conclusions.

I think it can be proved by the fact that we could have a series of instruments making the measurement without human (consciousness) looking at it.

at some point when the human reads from these instruments he/she would see the results happened prior to his/her looking.

one could still argue that the instruments results only happened when a human looked...but then we could have a clock.

one could argue that even the clock happened when the human looked...but then

you have a clock and so many instruments...now not all of them could be waiting for a human consciousnesses to trigger their results...

second if someone applied the above argument then it would be applicable to the whole universe and the universe did not exist till human consciousness looked at it...

long story short...(most/all) things happen in the universe without humans/life/consciousness looking at it...

Heh... you noticed!

(Always trying to be polite to new posters... they may not appreciate some of us sharks.)

So just wondering, itsonelouder... is eleven really one louder than ten?

:biggrin: it is, but not as loud as 12, which is really pushing it!
