Quantum Gravity

The case against science is straightforward: much of the scientific literature, perhaps half, may simply be untrue. Afflicted by studies with small sample sizes, tiny effects, invalid exploratory analyses, and flagrant conflicts of interest, together with an obsession for pursuing fashionable trends of dubious importance, science has taken a turn towards darkness. As one participant put it, “poor methods get results”. The Academy of Medical Sciences, Medical Research Council, and Biotechnology and Biological Sciences Research Council have now put their reputational weight behind an investigation into these questionable research practices. The apparent endemicity of bad research behaviour is alarming. In their quest for telling a compelling story, scientists too often sculpt data to fit their preferred theory of the world. Or they retrofit hypotheses to fit their data. Journal editors deserve their fair share of criticism too. We aid and abet the worst behaviours. Our acquiescence to the impact factor fuels an unhealthy competition to win a place in a select few journals. Our love of “significance” pollutes the literature with many a statistical fairy-tale. We reject important confirmations. Journals are not the only miscreants. Universities are in a perpetual struggle for money and talent, endpoints that foster reductive metrics, such as high-impact publication. National assessment procedures, such as the Research Excellence Framework, incentivise bad practices. And individual scientists, including their most senior leaders, do little to alter a research culture that occasionally veers close to misconduct.

Unquestionable probity does not seem to be in evidence.

Untrue is misleading. back when electric current was a mystery there were multiple competing theories published. The electron theory won out by experimental validation.
 
The video:
https://www.youtube.com/watch?v=w0ztlIAYTCU&t=4m35s
it says that other current theories don't explain what or why there is a speed of light. Same with Planck's constant

It says string theory hasn't made any successful predictions and it isn't a theory of everything because it doesn't explain the speed of light or other constants.

Amazing assertion... I learned Maxwell's equations back in my first year of physics. Maxwell explained and mathematically modeled the propagation and speed of light back in the 1800s.

That is a rather odd wish list for a TOE. It appears to miss the point of a TOE completely.

So is there a formula that can determine the speed of light to an infinite number of decimal places?
I can't seem to find it here:
https://en.wikipedia.org/wiki/Speed_of_light
unless it is this:

Sorry if I misunderstand the nature of this

Light travels at precisely one lightyear per year to as many decimal places as you wish to carry it.

I don't think you have any idea what you are asking. That video was pure bull shit and WOOO,

It says they have 13 scientists. I assume that the model they're coming up with makes sense to them. Or do you think it is all nonsense? I guess it could be similar to scientists in a creation science organisation though in that case there is a lot of ideas they agree with (that the Bible is 100% factual)
BTW here are there papers:
http://www.quantumgravityresearch.org/portfolio/all-papers
Though even creation scientists write a form of paper.

Here
http://www.quantumgravityresearch.org/our-mission
they assert again:
"...in current models we accept the speed of light as a starting point from which we make other calculations. But there is no current theory that explains why the speed of light is what it is––or why the universe even has a speed limit in the first place...."

I guess their 13 scientists would agree with that...

That video was pure WOOO. Was the video produced by those "scientists" or was it produced by someone who presented their interpretation of what they mistakenly believe? Either way, whoever produced it is peddling WOOO.

You keep pointing to what the video said even though many things in the video are outright wrong. Example: we have known what light is, how it propagates, how fast it propagates through different mediums, what characteristics of the mediums determine the propagation velocity, etc. (free space, water, glass, plastic, etc. are all mediums with different permittivity and permeability so each will determine different light speeds through them) for over a hundred and fifty years now and yet the video asserts that, "there is no current theory that explains why the speed of light is what it is". Maxwell explained exactly that in the mid 1800s and his equations have been repeatedly confirmed ever since. Not only has Maxwell's equations been continually confirmed but much of our current technology works only because we can rely on those equations.
 
....we have known what light is, how it propagates, how fast it propagates through different mediums, what characteristics of the mediums determine the propagation velocity, etc....
This is what the site says in the "our mission" section:
"...in current models we accept the speed of light as a starting point from which we make other calculations. But there is no current theory that explains why the speed of light is what it is––or why the universe even has a speed limit in the first place...."

So then why is the speed of light in a vacuum 299,792,458 m/s rather than 300,000,000 m/s? (what is Maxwell's explanation?) And why is there a speed limit in the first place? (they say no current theory explains this though I assume Einstein would have an explanation for the speed limit?) Maybe Einstein just knew there was a speed limit rather than explaining why there had to be one? I hope you can answer those questions.

Many creationists claim that light could have been faster in the past but the people on the site might say that the speed of light can only have its current value.

Because of the length that we arbitrarily made a meter. There is nothing in nature that makes a meter the length it was assigned by us.
(what is Maxwell's explanation?) And why is there a speed limit in the first place? (they say no current theory explains this though I assume Einstein would have an explanation for the speed limit?) I hope you can answer those questions.
Einstein accepted Maxwell's explanation because it was right. The speed limit is set by (as I stated in my previous post) the permittivity and permeability of the medium the light is passing through. Those properties of free space determine c. Maybe you should read up on Maxwell rather than watching the videos of WOOO peddlers.

Creationists claim all sorts of things.

Would you explain exactly how and where you think Maxwell was wrong since you seem to be so certain that he was?

I mean if the distance of a metre was constant... I thought that makes sense?
https://en.wikipedia.org/wiki/Speed_of_light
Wikipedia says "Its exact value is 299,792,458 m/s... It is exact because by international agreement a metre is defined to be the length of the path travelled by light in vacuum during a time interval of 1/299792458 second"
https://www.youtube.com/watch?v=w0ztlIAYTCU&t=4m35s
That video says "we will never be able to measure the exact speed of light without a theory"
"they use an inexact measurement of the speed of light"

I think if the speed of light doubled then the measurement of a metre would double... but I thought the sizes of the atoms, etc, wouldn't double?

I'm talking about the speed of light in a vacuum i.e. the maximum value.

Yeah it looks like many don't think that the speed of light can change:
https://en.wikipedia.org/wiki/Variable_speed_of_light

Would you explain exactly how and where you think Maxwell was wrong since you seem to be so certain that he was?
I'm just saying that those 13 scientists seem to be agreeing with those quotes. I know hardly anything about Maxwell. I am using argument from authority.

Yet again, the video is WOO. It says all sorts of nonsense (pretty much like the nonsense of creationists). We have a damned good theory and have had one since the 1800s.

Maxwell applies (as posted earlier) not only in vacuum but in any medium. If you want c in a vacuum then look up the permittivity and permeability of free space and plug those values into Maxwell's equations. You will find c to be what you found in Wiki after doing the calculations.

Then you should question that authority and look for one that isn't so obviously flawed. I would suggest someone like Richard Feynman or Einstein since you don't like Maxwell who both Feynman and Einstein accepted as an authority.

ETA:
Since you seem to assume that anyone who calls themselves a scientist is actually doing hard science, you may check out the team of scientists here and consider how much weight someone calling themselves a scientist carries:

http://www.icr.org/research/team

Most of these "scientists" are PhDs doing their "scientific research" in creation science.
 
What about this:
excreationist said:

I think if the speed of light doubled then the measurement of a metre would double... but I thought the sizes of the atoms, etc, wouldn't double?
The amount of atoms per metre would vary if the speed of light changed yet the measurement of the speed of light would be constant? (maybe I'm confused)

....Einstein accepted Maxwell's explanation because it was right.

Maybe there would be videos that can explain Maxwell to someone like me who has only a high-school level knowledge of physics.

...Would you explain exactly how and where you think Maxwell was wrong since you seem to be so certain that he was?
I just was trusting that organisation more than someone on a messageboard. It's odd that they can do all that research (they have a few papers) but apparently be totally wrong on such basic things.

BTW apparently the 13 scientists are being funded by private donations.

The speed of light is what it is. We invent arbitrary time and length standards that we use to express that speed. The second could have been any span and the meter could have been any length. Suppose we had used the heart beat to define time so each pulse we would call a second. Suppose we had picked up a stick about the length of our leg as a standard and called it a meter. Now measuring the speed of light would give us a very different speed as expressed in in our new M/s but the actual speed of light would not have changed. Any arbitrary standard for time and any arbitrary standard for length can be chosen but they don't effect the speed of light, only how we express that speed in the unites we arbitrarily selected.

More simply, if the standard for the meter had been a cm shorter than the one we currently use then the speed of light would still be the same but would pass more of the number of these new, and shorter, meters each second - expressed as more M/s than currently.
Maybe there would be videos that can explain Maxwell to someone like me who has only a high-school level knowledge of physics.

Yeah, their funding source is pretty much like those "scientists" (who also have PhDs) over at the Institute for Creation Science. I might also add that the "scientists" over at ICS have published a lot more papers. Reality and truth isn't determined by degrees or number of papers published but by the independent repeatability of what is claimed.

Holistic? Healthy? Metaphysical (although metamaterials exist)?

We could Ambrose Bierce these words, but I am developing a tendency to see what is meant, rather than what is said.

So emergence means (well, not exactly, but figure out what I mean, not what I say): "we switched focus from one scale of interaction to another that has to be mathematically described in a different way due to certain vague infinities and variables that we feel comfortable sweeping under the rug because it works at the scale I mentioned previously".

There is emergent vagueness in that statement.
 
Not to put too fine a point on it, bip, I think the excreat is voicing the same kind of hope that am I...that there might be someone within, or associated with, the scientific community, who is trusted and can explain these types of topics to the massive portion of the populace which is not skilled in the types of thinking, nor has the necessary tools to test the repeatability of complex scientific constructs.

So far, I believe you've told us to learn the science, so we would know. Frankly, I don't think you'd like the outcome if we all did, because your particular specialties in a world of specialists would be considerably degraded because so many others in your society had learned all the skills which made you special and deserving of extraordinary pay and status. I also can't be arsed to spend that much time, nor to spend that much on the tools to test all the claims made by physical scientists. I would rather that truly skilled physical scientists do that and become marginally skilled enough to communicate their findings to a general audience with some comprehension by their audience.

What I'm seeing is a two-fold problem. That pseudoscientists are getting quite good at stepping in and doing exactly that...explaining concepts so that a general audience feels that it has a better grasp of those concepts. I suspect that much of that arises from the scientific community by and large blowing off that aspect of their science, explaining it to the non-scientific public, as a waste of their time and their crayons. Then comes the problem of 'who do you trust'? Why is it we should accept the claims of one proponent over the claims of another? Sez who? As noted, some scientific fields are not particularly pristine in their applications....

Frankly, when 'scientists' start posturing like they were some kind of demi-god, not to be questioned because they had the magical letters behind their name, then I start looking for what it is they are attempting to obscure from plain view with their puffery and hand-waving.

When I watched the video, I found it engaging until they lionized the 'popular science' types of the Wu Li masters, and....postulated the whole thing hung on the necessity of a pre-existant universal conscioussness. I interpret that as a lame attempt to insert 'God' back in to the equation.

ETA: I've heard the 'furlongs per fortnight' explanation of the speed of light, but it still does not answer why that speed of light is always the same and is it a wave or a particle? What is a quantum? How does quantum mechanics work? Why is there not a yet discovered unified field theory which simply and elegantly links all the aspects of our physical reality together?

Could be, I suppose. Or, it could have inherent vagueness, which is expressed as an emergent 4D reflection, and thence translated to a 2D stick figure in the sand.

Can you describe to me 'quantum entanglement' such that I would understand it? I understand that this is also known as 'spooky action at a distance'.

Indeed, I understand and agree. The problem is, however, that explaining scientific principles can not be done simply - it requires that the person being explained to has the background tools to understand. Science is an intellectual pursuit that requires the pearson learning it to have actual understanding based on previous experimental findings that can be built on while pseudoscience goes straight to emotional appeal and wish fulfilment frequently relying on baseless or even anti-factual assertions. Visit one of the uncontacted tribes in the Amazon and demonstrate an LED flashlight. When asked how it works, they would and could not understand a description of electricity, the electronics, battery, etc. because they wouldn't have the background tool box but would embrace an explanation of "it's a gift from god".

Obviously pseudoscience "explanations" will always be more appealing to those seeking assurance and confirmation. Science is harsh because reality doesn't give a fuck about our desires or emotional comfort.
ETA: I've heard the 'furlongs per fortnight' explanation of the speed of light, but it still does not answer why that speed of light is always the same and is it a wave or a particle?
The speed of light is determined to be a constant because of a hell of a lot of experimentation, not because science wanted it to be. In fact, that finding was contrary to what was expected by science, science had assumed a universal time.
and is it a wave or a particle?
The descriptors wave and particle are models, not necessarily reality. In some applications such as antennas, it is best to assume wave characteristics because it works. In some applications such as photoelectric effect it is best to assume particle characteristics because it works.
Why is there not a yet discovered unified field theory which simply and elegantly links all the aspects of our physical reality together?
Because humans are not omniscient. If we were then there would be no need for science. Our understanding advances a little at a time, step by step, each step relying on the previous steps. Why didn't people understand computer technology in the 1800s so they could have had the internet?

I can give a simple description but can't guarantee you would understand it.

The very first thing is, forget the nonsense that pseudoscience has claimed about it. Start with a clean slate as if you had never heard the term "quantum entanglement".

If a pair of particles are created in an energetic event then they will have complimentary quantum numbers because of conservation principles. i.e. if one is a spin up quantum state then the other will be in a spin down quantum state. That is, the two particles are entangled. Change the state of one of the particles and they are no longer entangled.

Entanglement is simple. The problem is in interpretations because of other QM principles.
