that is exactly what i have been going on about for a while...
A leading edge of a membrane/bubble, a trailing edge/brane and a universe in between, all expanding at lightspeed so if viewed from a point of reference outside of the universe it would appear to be a bubble 13.7 billion light years thick.
Do you remember my " Wave of Thought" posted in a thread about a month ago ???...well I've been refining it, check this
light/energy remains in a fixed position, is propagated in at least one dimension of string theory and the universe by virtue of the spacetime bubble expanding at lightspeed creates the illusion of light wave movement towards us. I think to check this would require a frame of reference which is outside of the physical universe given we are always observing from within the system and i don't know if that's possible.
Meaning light isn't moving towards us as a wave we are moving towards it, we just have no way of telling because the light source, us, everything, is in motion relative to everything else in the universe.
I see the light ...uh no it sees you
This makes it possible for light to be an effect of a string operating in at least one dimension and a crossover dimension of time. Time being the thing which links our 3d universe to the other dimensions. It also makes it possible for our universe to be embedded in a bubble skin which is equivalent to being trapped between 2 branes and expanding at lightspeed in a higher medium
This brings to mind the classic people interacting on a train scenario. They are moving about to and fro from carriage to carriage appearing to move in relation to each other or remaining stationary yet when viewed from outside the train the whole thing is moving forward meanwhile the sun is shining on the train and thru the windows from a point outside of the moving train...
... But what if the engine pulling it at the front is travelling faster than the later carriages so you get a stretching effect only the people on the train have no real idea just a sense of things moving awkwardly when looking out the window ???
I even posted it on a "string/brane" site to see if it got any feedback but nothing as yet I also posted this which ties in
I was wondering if all variations of string shapes could be made from sections of a figure 8 shaped string which co incidentally or not is an infinity symbol ???
closed loops, open loops, straight sections even X shapes can be made from a figure 8 shape
then imagine that each of the 11 points in the above figure represents a dimension that the string vibrates across but it needs to pass thru the cross over point of time and 3 others to register as a physical object in our universe. A string that vibrates in only one dimension plus time registers as an effect like gravity or light...ie a graviton or photon. Given that a string can change shape it could disappear from our universe and back again by vibrating in and out of any number of points/dimensions in the exact same 4d spacetime co ordinate and change the nature/state of whatever occupied that space previously.
Am I making sense ???...then try this,
ripples in a spherical pond with light,gravity and matter constantly reconstituting itself from it's fundamental string building blocks. A virtual multiverse propagating itself all the time, all around us. We just aren't aware of it because we are trapped in our 3dimensional + 1 dimension of time, universe.
What would be cool is if consciousness/awareness were a hidden dimension of string theory as well ???
