I heard the holographic principle is a sham and that there is no evidence to back it up and that 99% of physicists don't accept the idea as credible.
Is this true?

The mistake, I believe in arguments beginning with discussions of the event horizon of a black hole is the assumption, simultaneously, of a stationary black hole and of in-falling "information" (with its requisite matter-energy) which will alter the event horizon of the black hole. Of course one is being a bit loose here and the not-quite stationary behavior is understood... or apparently so. But there are easy traps to fall into, exemplified by apparent paradoxes such as the BH info paradox. t'Hooft made a more complete analysis of Hawking's BH information paradox around these lines. (according to wikipedia). I would say it this way, one is not so much mapping to a 2-dim membrane but rather a 3-dim "thin" neighborhood of a 2-dim membrane when discussing BH's horizons encoding of infalling info. (Note this is also necessarily true of non-monochromatic actual holograms. One must use a photographic emulsion with some thickness rather than a simple planar pattern. So I'm still in a sense describing a holographic principle.)
Now I don't know if my answer addresses your question as you did not give any specifics as to what you think the holographic principle says. So I'll listen out for further queries.

The simplest answer is - undetermined. There are good reasons to think it might be right, but also there are good reasons for not being convinced.Chrisjohnson said:Im just wondering if that's right, wrong, or undetermined. A short elaboration is welcome but I don't want any of you to waste your time with extremely technical explanations because I don't have the time or energy to interpret it.

Chrisjohnson said:Well I didn't hear it from a well respected physicist or anything, it's just my friend who's teacher in physics 101 (or whatever) told him that the holographic principle was completely inaccurate and has little to no evidence to support it.
cosmik debris said:It's a theory and as such it is not inaccurate and certainly not completely inaccurate. It is accurate in the sense that there are some axioms and some assumptions and from these it makes sense.
StevieTNZ said:I should mention the word theory does not mean its normal definition in scientific context.
The definition in that area is "a comprehensive explanation of some aspect of nature that is supported by a vast body of evidence."

I am not planning on taking classes but physics still interests me and based on the little research i did on this (because it was interesting) it's supposed to be a legitimate theory accepted by many people.

craigi said:There's no sham. The holographic principle is property of string theories. I'd suggest you start with the easier question of - 'what is the evidence to support string theories?'.
Whether 99% of physicists accept the holographic principle as credible is a very misleasing statement, for two reasons, no such survey of physicists has been conducted, secondly to understand the holographic principle requires highly specialised understanding of theoretical physics, which very few physicists have. As a ballpark estimate, I would say that only about 1% of physics graduates actually go on to the prerequisite subject matter in order to properly understand the holographic principle.
For the purposes of training your own critical thought, and that of your friend, I think it would be useful to go back the source of your information and examine it more carefully. I suspect that what actually happened was that your friend raised the subject of the holographic principle in an beginner physics class and was offered direction towards understanding the basics first. There's also no particular reason to believe that someone teaching a 'Physics 101 class' would have a strong understanding of the holographic principle.
told you my teacher said it. we went over this. you can ask her for her sources.DrChinese said:I requested Chris provide this, but so far he has not. How can we rationally discuss something someone "heard" ?

The holographic principle is a theory in physics that suggests that the information contained within a certain region of space can be represented by a lower-dimensional surface. This concept was first proposed by physicist Leonard Susskind in the 1990s.
While there have been some experiments and observations that seem to align with the holographic principle, there is currently no concrete evidence that definitively proves its validity. It remains a topic of ongoing research and debate in the scientific community.
If the holographic principle is true, it could have significant implications for our understanding of the universe and the laws of physics. It could potentially lead to a better understanding of black holes, quantum gravity, and the nature of space and time.
Yes, there are alternative theories that attempt to explain the same phenomena as the holographic principle, such as the "fuzzball" model and the "entropic gravity" theory. These theories also lack concrete evidence at this time.
Scientists are currently conducting experiments and observations, such as studying the behavior of black holes and examining the cosmic microwave background radiation, in order to gather more evidence and insights into the holographic principle. There is also ongoing theoretical research and modeling being done to explore its potential implications.
