Quantum Mechanics (Chapter 6 of 6)

Once you get past existence coming and going... and virtual particles... and uncertainty... and exclusion, then you are ready to enjoy the REALLY weird stuff in the quantum world.

Does this mean that mere observation directly influences the state in which a particle can exist ? How does the particle "know" that it is observed ?

[cassiopeiaproject]

@thruid3 It isn't "observation" that triggers disentanglement, it is any interaction that is not reversible. Since observation requires such an interaction of some sort, it is often wrongly cited as causing the disentanglement.

[thruid3]

Ok, the wave of a particle collapses when observed. Then the other entangled particle instantly settles into the opposite spin state. Does that mean this information can travel any distance instantly ?  How does that work with speed of light barrier ?

[cassiopeiaproject]

@thruid3 Yes, instantly. No one knows how that works with the speed of light barrier. It is an ongoing investigation. So far, though, no one has figured out a way to use this instant effect to send a message or other information.

Hey Man I have to say thank you...I am in the caribbean and this has been nothing short of extremely helpful! I am going to subcribe hopefully you can answer my questions in time!

INFORMATION TRAVELS INSTANTANOUSLY FASTER THAN SPEED OF LIGHT. INFORMATION IS A MORE FUNDEMENTAL CONCEPT THAN SPACE , TIME , ENERGY , MATTER , CHARGE , SPIN , FIELD ETC.

[Assaultous2]

NO INFORMATION CANNOT TRAVEL INSTANTLY AND FASTER THAN THE SPEED OF LIGHT...... yes u are right, they disentangle instantly, but the information is random; you cannot choose which state it will be in; your electron might be spin up and the other spin down, or viceversa, so u ARE sending information, but it is totally random, so doesn't really count as information......... Hope this helped....

I am just learning about quantum physics, but i would guess that the electrons, when they disappear from our world goes to another universe in where they might be in state before the big bang as stated earlier, when all particles are together.

[ThermalHD]

@cassiopeiaproject if two electrons with opposite spin on each side of earth is entangled, can we then say they are a part of a field?

[Roronoa79]

Chuck Norris can observe electrons without collapsing their wave functions
