From what I’ve read of the subject, a lot of modern physics consists of the manipulation of mathematical formulas that are largely self-referential and bear little or no relation to reality. A lot like modern economics, in fact. The laws of logic, causality and identity are just so old school, I guess.
Basically, a key piece of mathematics creates bulk masses of fermions that are manifested in the so-called fifth dimensional warped space. This pocket “dark sector” is one possible way to explain the huge amount of dark matter that, so far, has eluded detection using any traditional measurements designed for the standard model of physics. Fermions jammed through a portal to a warped fifth dimension could be “acting as” dark matter.
Dennis do you have any university level physics or even advanced high school level physics? Are you looking at physics from a position of near total ignorance?
If so why bother … to paraphrase Darwin “a dog may as well ponder the mind of Newton for Dennis to ponder the state of modern physics”.
You don’t have to get beyond “a key piece of mathematics creates bulk masses” to know that the law of causality has been violated by this theory, or at least the theory which Popular Mechanics is trying to explain here. Mathematics cannot create a physical existent. You don’t need a degree in physics to figure that out. There’s a physicist by the name of Bill Gaede who has published reams of videos debunking many of the key concepts of modern physics. Insulting me doesn’t advance your case, by the way.
Indeed, his insulting you does not advance his case. But if it improves his mood, confidence, and vocabulary, perhaps we should indulge him, for the wider good?
shouldnt that be ‘Higher Unlearing’?
my bias comes from my autism via which l learned REAL EARLY to put my faith in tangibles, (regrdless of scale).
lm uncomfortable around the notion of dark energy. l know an astronomer study the spin of galaxies discovered the outmost stars didnt ‘lag’ as they should, the spirals were not as pronounced as they should be, leading to the convincing conclusion there was more mass further out causing a drag.
anyways.
l have a theory the entire solar system large bodies, ie all planets and moons were all or almost all the result of supernovae occuring when things were much more cramped and thus not so prone to blast aport in a nebula.
to me it explains where the iron core came from, easy, the remnants of all the iron sinking to the middle of the star that became the earth.
and why the profile of proportions of elements in all the planets and moons varies so much; NOT from common swirling dust cloud but rather an expected difference in the exact nature of each supernova. ie *proportions* of which heavy elements created in those brief moments.
and how did the gas giants come about? easy, they scooped up all the loose gas left over from dozens of clustered supernovae.
l lack the mathematics to develop the theory but being an amateur it suffices for me and never disputed.
another theory, the full extent of the whole universe could be 1,000s times what we see, but is nevertheless FINITE and the ONLY ONE EVER.
whats beyond the ‘edge’? thats easy too, merely the SAME ‘realm’ before the Big Bang, dimensionless timelessness, into which the always and currently expanding universe is CREATING dimension and time.
its God’s realm. and here’s the kicker IT OVERLAPS THE 3 DIMENSION EXISTENCE WE ARE IN.
at the mens’ prayer meeting l explained THIS is how He appeared in the locked room after His resurrection, by manifesting Himself at that ‘point’ of ‘overlap’ that coincided with INSIDE THE LOCKED ROOM.
evidence? teasing hints? subatomic particles appearing out of ‘nowhere’ and vanishing ‘back’.
because thats the ‘from’ and ‘to’ parts explained to my satisfaction.
l also figured out more about ye olde E=Mc2. thats the math, the equivalence, but HOW does mass BECOME energy? what is the mechnism of TRANSFORMATION?
that for another day.
aka ‘seeing is believing’. and l cant ‘see’ dark energy even in my mind’s eye so thats out.
Your third paragraph: my opinion is that the big bang is when the event horizon formed around the black hole within which our universe exists. More energy comes into the system as more host universe matter/energy is absorbed and distributed to ours. This results in a seemingly runaway expansion and ripples in space/time where the energy is added. Our universe, in turn, produces more sub-universes as black holes form here. As black holes eventually succumb to the Heat Death, so too must each universe.
Sounds either nice or strange, but our reality is likely closer to dark energy and dark matter being the crystalline spheres of our age: a mathematical necessity to extrapolate a greater system from what we know and are comfortable with into unknowns that cannot exist is our current frame of reference. It might be wrong, but it makes the math work in a comfortable and predictable way that results in predictions that aren’t wrong.
Yup. “dark matter, black holes” translated: “we strive to Save The Appearance of knowing.”
But it’s worse than that as recent (40 year) history clearly shows
science had always been able to humbly share “theory” along with corollaries and unknowns
in order to test, advance, or drop, the theory.
Todays so-called science jornolithp,
who doesn’t understand his topic and whose only message is Climate Change!
can’t publish anything unless it contains 99% speculation, making it unreadable, literally science fiction.
Long March Thru Institutions dumbs everybody down.
I wonder how much this is costing us.
In these times a fifth dimensional warped space of dark matter crammed with fermions makes perfect sense as a way of balancing the made up physics of the universe. But my money is on a curved hyperspace with clusters of purple-haired lesbians (I have no horse in that race). It better reflects the direction of modern science and it explains the “lost mass”.
You know it’s a theoretical structure when it can include purple haired lesbians losing mass.
Fermions. Are they not shed by Klingons as spring approaches in the eastern hemisphere. An abundance of god particles have gone up someone’s nose to manifest this assertion.
“jammed through a portal to a warped fifth dimension” = “stuffed up Satan’s ass”
Sounds like technobabble from Star Trek TNG. Dark matter… The universe is mostly made out of that stuff. But they can’t find any. In engineering that would be called a bullshit theory. Find me some dark matter or get a better theory.
Sounds like technobabble from Star Trek TNG. Dark matter… According to them the universe is mostly made out of that stuff. But they can’t find any. I guess all that dark matter went where my homework went.
Is the search for dark matter raciss?
Maybe they find it in a black hole?
I think there is a lot of dark matter in Africa and inner-city ghettos.
Exotic matter, even.
Surely the best place to search for dark matter is Stephen King’s back yard?
Why did she decide to attempt to translate a study from 2021, and do a poor job of it?
Space isn’t supposed to be warped by gravity and time isn’t supposed to slow down the faster you go, either. But here we are. It took fifty years for instrumentation sensitive enough to test general relativity to be invented and used to support the theory. Maybe cool your jets a bit before deciding that math you haven’t got the training to understand is bogus.
My next band, the Jet Coolers.
From what I’ve read of the subject, mathematics was well past what’s understandable to the man of the street by the year 1800, and physics started to use very advanced mathematical concepts well before 1900. As a consequence, while it is possible to explain the concepts of quantum electrodynamics in terms that are somewhat within the limits of common sense, the more generic theoretical physics has not been easily understandable for 60 years, if ever.
I’d invoke the famous Nobelist Richard Feynman here: it doesn’t matter who you are or how beautiful your theory is, if it does not match the experimental results or observations, it is not the correct or at least, not the complete theory.
That said, I’m perfectly okay with a fifth dimension that’s heavily curled. I have behind me just a few years of university level mathematics and physics. I’m no way competent to criticize these conjectures. I’m also not very much agreeing with the Sabine Hossenfelder style complaints. Sure, much of the theory will be wrong and it is written for the sake of doing research rather than with certainty it is true or even a good theory. On the other hand, the ladder from Einstein to Feynman, Susskind and Witten is very solid. I think these people are geniuses.
So please sit down and listen to Susskind, when in doubt.
Witten might be one of the smartest people ever, but he’s spent his whole career chasing strings and getting nowhere. I personally find him excruciating to listen to as well.
Dark matter has never been observed. Its existence is merely inferred from the fact that our observations do not match our theory.
This indicates that it is our theory of gravity which is in error, not the universe.
And, we already know that gravity and quantum mechanics don’t play nice together. And the device you’re reading this on demonstrates that QM is correct.
Dark energy has never been observed either, again merely inferred from the discrepancy between observation and theory – the same theory of gravity.
Conclusion: the theory is wrong, or at best incomplete. I strongly suspect that we understand neither space nor time as much as we think we do.
Physics has been in a rut since the late 1960s, right around the time string theory sucked all the oxygen out of the room. We need better theories.
This was a hot topic decades ago – is the theory of gravity slightly inaccurate in that sense, or is there dark matter that we don’t know how it fits the standard model of particle physics. These are the two obvious possibilities. I think the standard model is the main culprit here.
You are right in that quantum mechanics needs to be made consistent with the theory of gravity. My view is that they’re both inaccurate in extreme conditions.
The general opinion among people who should be able to guess appears to be that the GR doesn’t fail a single test where it can be tested accurately, but only breaks inside black holes and temperatures much higher than 10³⁰K. The quantum mechanics is equally amazing.
Like Celander, I’d also invoke Feynman: It is absolutely necessary to make constructs. And, “the test of all knowledge is experiment. Experiment is the sole judge of scientific ‘truth’.” The hare-brained ideas will fall by the wayside.
There have been many phenomena that physics could not explain at first. For example, statistical mechanics could not explain the ratio of the two specific heats of gases (at constant volume vs constant pressure). This was first noted by Maxwell around 1860 and remained a mystery until quantum mechanics.
If this 5th dimension thing explains what isn’t observed (!), more power to it. But how are fermions crammed together?
