Any one else here obsessed with physics?

Watching this one while I eat. Still only on Greene, for a nice overview for context for the Q/A session.

 
I'm enjoying the discussion of holograms and black holes. I don't particularly care for the string-theory based holographic model. In my mind, a hologram is defined by using N-x dimensions to express N dimensions of information. It could be that the "decoding" that we get from the event horizon is just not getting the "laser shined through at the proper angle" to distinguish the encoded information. Also, who says it has to be a singularity in a black hole? Honestly, it is all just theory. And I do think it is predicated on an incorrect assumption about the limits of c and what it really means.
 
My problem with c (the speed of light in a vacuum). It is basically a limit. As such, it should be asymptotic. As such, nothing can have the speed of c. The idea that light (in a vacuum) travels at c, denies the almost obvious asymptotic limit rule. That never sat right with me.
 
the main issue with the speed of light is it is not possible to read it in multiple directions at the clock would have to move at the speed of light to measure it see Einstein convention. I'm not a follower of string theory lack of super symmetry is killing it quick.
 
Adam If you want fun check out "Chris the brain's" U tube videos, he like us is a physics amateur very good.

Click to expand...
I just watched chapters 1-4 of his "fifth dimension" theory. Love it. I find it pretty obvious that if 3d warps, it has to warp through another d, he puts into nice words and expands upon it.
.
At the end, where he talks about space compression just by subatomic mass, the first thing to come to my mind was a 4d dot matrix printer creating a 3d image
 
of course, a new image is created along the causation axis, at say, Planck time intervals? Or some other constant? Or some limit? Which is variable time on that axis, but looks constant from the others...
 
I believe it would require no information loss from black holes.. for time to run both directions (reverse causation is still causation based in information)
 
Now you have hit a nerve . when I had the stroke three years ago I had an out of body experience while getting back to normal just prior to waking up a thought entered my mind it just said the answer you seek is information. and from that point on I had a deep desire to get more information so while in the hospital I asked my wife to order a course from the great courses called the science of information from language to black holes. What an eye opener
I learned about Claude Shannon this really opened my eyes and everything made sense.
A month ago a paper came out that correlated the size of black holes and the expansion of the universe. black holes gobbling up something dark matter? Information is the key to everything. information is energy.
 
That sounds like an interesting course (though having a stroke to prompt it doesn't sound fun). I hope you have recovered nicely from that.
.
I had this strange image half-asleep last night. Not sure I can describe, I may have to draw something. It does take into account a mobius strip twisting, or actually several, which ... I can at least imagine things moving backwards and forwards at once. I'll see if I can draw it later today, much easier with diagram.
 
As much as I can say without the very basic geometry, is that ... basically if something is moving clockwise on a mobius strip, and something at the exact same point but across the surface from it ... from a limited perspective one could say "on the other side" ... so one point in time directly across the strip, and it moves counterclockwise. The paths of each movement will never cross, because they are "mirror images" in some way, on the other side of the strip, and moving in different directions.
.
So things like "cause and effect" are reversed - becomes "effect and cause" for the other side. But for that side, measurements are taken differently due to the reversed motion, so they make sense for someone on that side.
.
Drawing will certainly help.
 
The main thing I'm unsure of, is if time/causality is a twisted surface like mobius, what does it twist through? Not wanting another dimension just for that, so maybe through the other 4...
 
your stuff computers and physics are starting to get really intertwined, starting with Claude Shannon's information theory and how it relates to entropy.
 
I do believe that source coding/data compression is what ends up happening on the event horizon of a black hole. The n-dimensional information is compressed into (n-k) dimensions, and can still be lossless (or more like a JPG, losses but algorithms to virtually decode). This fits in with a holographic framework, whereby the smaller the sample (or the less dimensions it is expressed on) has all the information, just fuzzier.
 
The latest I have read black hole surface contains the most information that it is possible.to store on a surface.
either way black holes is where it is at in physics Leonard Suskind's the leader in this research, Watched his latest video couple of days ago. The only old guy still moving physics forward.
 
oh yeah, I do like Suskind. I don't really remember what I read or watch or hear, I just incorporate it. Haven't thought of physics for a while before these forums here, so I'm catching up :)
