Did the early universe have one dimension ?

I would assume a 4th spacial dimension at right angles to the other three. The problem is that as 3 dimensional beings we can no more conceive of this 4th dimension than a 2 dimension creature living on a flat world would be able to think of "up" and "down". sorry i have to disagree. a 1 dimensional creature, could never think of any other dimensions because all it knows is itself. so even if a 2 dimensional creature tried to talk to it, it would think it was talking to itself. a 2 or higher dimensional creature would be able to see creatures in its dimension and lower. so it would be possible...

sorry i have to disagree. a 1 dimensional creature, could never think of any other dimensions because all it knows is itself. so even if a 2 dimensional creature tried to talk to it, it would think it was talking to itself. If you are going to disagree at least make some tiny effort to try and understand what you are disagreeing with as you have gone on to EXACTLY AGREE with what I was saying.

If you are going to disagree at least make some tiny effort to try and understand what you are disagreeing with as you have gone on to EXACTLY AGREE with what I was saying. sorry wasp but there is a difference between thinking up and down and seeing up and down. we can concieve, think how a fourth dimension might be to our three dimensions, we just cant see it. a two dimensional creature might have an idea what three dimensions might insue but it wouldnt be able to see it.

I'm highly baffled by this, it takes everything I know about the uiverse's beginning and tosses it out the window... Litterly.

In a 1-dimensional universe, everything would exist in the exact same location in space at the exact same time. A singularity. Edit: Okay - scratch that. a 1-dimensional Universe would be a line. Zero dimensional Universe?

Quantum Mechanics is completely deterministic in (2+1)D (or less) Universes. * Blinks * Are you entirely sure about that?

* Blinks * Are you entirely sure about that? Well I guess it depends on how you define ``deterministic''. In this context I meant that a local causal hidden variable theory can be constructed which would perfectly predict the result of any Quantum measurement. (The only good link I could find discussing this is here on page 16 of the pdf, but it is a bit abstract. My prof back in undergrad explained that the main problem with local causal hidden variable theories was making them consistent with the commutation relations for angular momentum. In 2D angular momentum is considerably simplified - ... [More]

Has anyone measured the ratio between the two binary states detected for particles over a given angle with a single detector? I don't understand your question. By binary states are you referring to (for example) up and down spin, or up/down and left/right spin? How are these particles prepared? (all in the same configuration? Evenly random configuration?) From the context, it sounds like you are talking about something like this: A beam of electrons with vertically positive spin (angle = 0) is produced, A Stern-Gerlach detector is placed in this beam, The angle of the detector is varied betwee...

From the context, it sounds like you are talking about something like this: A beam of electrons with vertically positive spin (angle = 0) is produced, A Stern-Gerlach detector is placed in this beam, The angle of the detector is varied between 0 and 90 degrees, and The polarization of the spins (up or down with respect to the detector) is recorded. Is this what you ... [More]
