The illusion of distance and free particles : quantum entanglement

The illusion of distance and free particles : quantum entanglement.

Two particles linked together with a bond which is beyond comprehension. Changing the state of one of them, changes the state of the other one even across universe with an unknown bond.

It would be interesting if one of the entangled particles was accelerated to near the speed of light, and seeing if you could measure one of the particles, thus sending a message back into the past or into the future. If entangled particles react instantly across space, shouldn't this be the same for time?

[paralaks]

If that is possible then I think you don't even need to accelerate an entangled particle. I mean if all past-present-and future exist at the same time (watch my other video about this), is there a sort of membrane separating them? If not, then perhaps a particle can be entangled with a particle in the past.. then what... I don't know! lol!

Walter's shirt is more ridiculous than entanglement.

How is this even possible? It's like physical space, as we know it, Isn't real at all. Can we make the assumption that we could be living in a sort of universe were all the dimensions are linking to each other in some contraction of physical space? Sorry, i'm just a 17 year old physics student, don't know much yet.

I think it wouldnt :). Speed of light is a limiting factor for the 3D space as we know. If entangled reaction is faster than speed of light (it is according to observations) then one consequence would be , that 3D space is not 3D and particles are not seperate objects rather waves or multidimensional spaghettis from which we can see only intersections.So traveling with one end of the spaghetti in 3d is independent from the act when you pull it in the other direction. At least I think so..

[Tamás Koncsos]

I think: One consequence is that space is absolutly different we see. Think about a paper , take a needle and a thread and push the thread through two points. Now we are limited to observe the universe as a paper and the thread as two seperate objects. You pull a section of the thread at one point and it will have an effect on the other. So my question is:

1) Particles are not particles rather intersections?

2) Why is macrophysical observation limited to 3D ?

3) Whats the real space time model?

Who is Islam. Who created it. What do you know about it. All information you'v got on Islam has been transmited, wrote and developed by people.

[paralaks]

I think you missed a discussion here since the user who I was exchanging ideas had deleted his messages (I deleted mines as well to prevent a future confusion). What started all these was my comment: "I believe in the Creator more than my own existence -all in all what is a human from pure scientific perspective? random (or strictly predetermined) particles bonded together)." Clearly I am not saying what God is, I am saying: "without God I don't know what I am". And Islam explains Allah, not me!

[Julian Dervishi]

if you are a human, than you know still nothing about universe. If you talk here about "God" i'm gonna ask you what is it? Who are you to tell us about a creator. Personally i like to learn as much as possible. Smart people try to understand the reality around being always suspicious on what they get. People like you find it easier to point all the things somewhere. Acording to islam, you can't tell us if creator exist or not. You'r not the creator and you never met him so mind your own business

[Eric Lester]

That would require it to have to be a 1/2 phase shift EXACTLY. Otherwise it would only partially deconstruct.

Maybe the answer is, there's no such thing as a distance, there's only time which defines everything.

[MaGetzUb]

With a coherent light beam, such as laser. I guess.
