Thank you for putting a light on this issue.

"We know dark matter exists by the way the universe is shaped." ...Which we don't actually KNOW at all, but have calculated mathematically and also built a whole mathematical framework to support, and if that's wrong, well, we know nothing. We made our equations agree with each other and input variables we can't explain to make them come out right. Proof! Great science there.

The missing mass is dilated mass. We have all heard the phrase "mass becomes infinite at the speed of light" this phenomenon is illustrated in a common relativity graph with velocity (from stationary to the speed of light) on the horizontal line and dilation (sometimes called gamma or y) on the vertical line. Mass that is dilated is smeared through spacetime relative to an outside/stationary/Earthbound observer. Wherever you have an astronomical quantity of mass, dilation will occur because high mass means high momentum. There is no place in the universe where mass is more concentrated than at the center of a galaxy. In the 1939 journal "Annals of Mathematics" Einstein wrote about dilation occurring in regions that would have less mass than that which would exist at the center of common spiral galaxies. Therefore it is safe to say that according to Einstein's math the mass at the center of our own galaxy must be dilated, in other words that mass is all around us. It was recently discovered that low mass galaxies (like NGC 1052-DF2) have normal star rotation rates. This is what relativity would predict because there is an insufficient quantity of mass at the center to achieve relativistic velocities. A simple way to confirm this would be to calculate the star rotation rates of a large number of galaxies. This would show that all the high mass galaxies would have star rotation rates that seem to defy the known laws of physics and all the low mass galaxies would have predictable star rotation rates.

I have long found, I get as much understanding out of reading many of the comments, as I do from the lecture itself. The questions raised are answered by other watchers, or the presenter, and they typically are questions beyond and outside of the direct aspects of the lecture. This is certainly true regarding this lecture. Thanks!

Smashing atoms is materializing dark matter... literally! ''dark''...'''matter'''

Coming at this as a layperson, I find it fascinating that the fact dark matter forms a halo suggests it acts like a field; perhaps even the "donut," if you will, to the "donuthole" of the galactic matter that the former flattens or locks together gravitationally. I often wonder if the supermassive and other black holes might create this halo by some quantum or other effect. Questions I have include: How are we sure dark matter is even present WITHIN our galaxy? Do we see absolutely NO hesitation before galaxies collide that might reveal dark matter? If not for dark matter, would stars near the edge of galaxies simply fly away moving at 220km/s? And would the universe then be more uniform (chaotic) with rogue stars and planets? What part of a spiral galaxy still remain in that case? About a half? A third? 3/4?

Fascinating thankyou

That's honestly super interesting

Dark matter is a hypothesis which allows a mathematical description of "local" anomalies in the fabric of space-time. Dark energy allows a description of the observed anomaly of accelerating cosmic expansion. Both hypotheses require a total of 20 times more stuff than the observable universe to fudge a correspondence between observation and theory. New physics is needed, but I don't know what it would look like.

"Information is information, not matter or energy. No materialism, which does not admit this, can survive at the present day" by Norbert Wiener, the Father of Cybernetics. If physics wish to survive, than have to recognize the same ontological status of Information, Matter and Energy. That is a key for paving the way to new physics. Because of the fact that physics treats the information as just an artifact of interaction of matter and energy, even at quantum level - no way to detect Dark Matter. Physics should embrace the idea that information can play also a cause role, not only as an effect's one. Thanks for nice and instrumental talk - very interesting.

Just throwing out an idea here: we're told that large bodies create gravity by 'bending' space-time, like a bowling ball on rubber sheet, to use a common analogy. Maybe the reason the galaxies spin the way they do is because, instead of bending, the fabric of space-time itself is spinning like an enormous disc, carrying the stars and galaxy with it. That's why they all move at the same speed. I fully expect any half-way competent astrophysicist to explain why I'm wrong. I'd appreciate the lesson.

21:30 "this is a great screensaver" This is a great screen destroyer, do you not remeber why we had screen savers?

We always see the graphics of mass warping a space time grid. What if when extremely massive objects (galaxies, black holes, etc) warp space time, it doesn’t just pop back to “neutral” when they move on? If it left a trail, something like a ditch on the space time grid graphic, wouldn’t gravitational effects still be observed? I don’t even know if this makes sense mathematically, I just like to brainstorm.

if the expansion of the galaxy is counteracted by gravity, so we're not getting bigger, what would happen if you were just floating between galaxies? would you expand?

This picture seems to suggest that matter is reducing over time (into black holes) and the vacuum energy or the space between matter and things is expanding - the less matter of both kinds, the bigger the vacuum thus increasing that vacuum energy and the expansion

At 3:16 Dr.Fisher refers to the expansion of the universe as acceleration, several times,which took me a while to tease out what he was actually saying. Kind of cast a pall over the rest of the lecture

False sending information through an entangled pair of particles is not possible as this would break causality. As we have no way to know if our particle will be the spin-up or spin-down , and we have no control over the collapse, it is not possible to send information through the collapse of the function. Once the function has collapsed, the quantum entangled state will be gone. What they proved was that our Universe is not locally real, which has to do with entanglement, but this is still not a way to brake causality.

General relativity is wrong, special relativity is correct. General relativity says it takes time for light to travel, hence a light year is the distance it takes ight to travel in one year. But that is not completely true under certain conditions. Like according to James Maxwell's equations on EM fields, when the observer or telescope is contained inside the EM field they are measuring, light information takes zero time to travel any distance. It brought on quantum entanglement's spooky action at a distance idea and the Einstein Rosen-bridge postulate about wormholes. General relativity says light takes time to travel. Quantum mechanics was right, general relativity was shown to be wrong. But like I said, only under certain conditions, like when the observer or telescope is contained inside the EM field they are measuring. Light information then happens instantly at any distance. According to Maxwell when the observer is contained inside the EM field being measured light has an infinite velocity. It's what sparked the EPR thought experiment into being called the EPR Paradox. It also sparked the Copenhagen Interpretation in quantum mechanics.

Existential Physics: Do all galaxies eventually collapse in upon themselves? Modern science claims that 'gravity' is matter bending the fabric of spacetime. There is a lot of matter in a galaxy which would make a huge dent in spacetime. How could galaxies not eventually collapse in upon themselves if spacetime were bent to make it so? (Or is modern science wrong about 'gravity', 'space', and/or 'time'?)

Perhaps because we cannot still quantify dark matter with the standard model, we may have to find another field of matter in the space/time metric from which we can propose a dark matter particle related to but not included in the standard model. Just a thought.

Then you know as much as the scientists trying to answer that question.

I greatly enjoyed your descriptions of your work. This dark matter and energy stuff - well - I think we need to remain skeptical. Last year I read an article by an E. European scientist who claims dark matter clearly doesn't exist. For dark matter, he argues, to "work" - to explain galactic rotation - it has to be a sort of donut structure outside our galaxy. But, this scientist maintains, almost everyone in physics ignores the obvious problem, that small galaxies or clusters orbit galaxies where this donut of dark matter is supposed to be. And these small galaxies or clusters are NOT impacted by this supposed dark matter. So dark matter can't exist. Well, that's one argument. MOND is looking better and better. There is a great chance that Dark Matter isn't real - doesn't exist. Dark Energy may also not exist. The universe may not be expanding in an accelerated sense. The so-called acceleration we seem to detect may be related to the idea that "uniformity" or "sameness" - that our assumptions about how this works in space were wrong. That you need a much, much bigger region of space before uniformity is real. We have detected structures that definitely throw off our old data, which was used to guesstimate uniformity of space. If space is not uniform at the vast region we thought it was, then some of the galactic redshif/blueshift we detect may be caused by something much simpler than "dark energy". Dark energy - and acceleration of expansion - may very well be myths/errors. There is a prominent physicist at Oxford, iirc, advocating what I'm saying."" Super symmetry has suffered a number of serious disappointments in the past 10 or so years. I don't want to sound disrespectful, but Dark Energy and Dark Matter are under serious attack in academia. There are strong reasons to believe these are flawed theories.

This acceleration is way too small to be measured directly. It can only be measured over a span of around 1 million years. In 1 million years the star or galaxy would have gained an extra 100 mi/h or 160.9 km/h in it's velocity. The older the star or galaxy is, the more motion they will have gained. This acceleration is the same for all stars and galaxies, regardless of their mass or missing mass. There is no missing mass or missing energy in the universe.

Need to be a bit more humble and then we might actually move the unexplained area forward.

The particle mass seems to be a mathematical solution for something like Andromeda data, but they never give the math of the first 500M years and galaxy formation from maybe a sphere 100 time the galaxies eventual size with very very weak initial gravitational attraction. You turn on a switch and the dark matter makes a quick trip 100 times the size of the galaxy in 500M years, then the switch is turned off and parks in position to make the Andromeda calculations work for the next 5, 10, 100 billion years with maybe a massive black hole pulling on it at a much closer distance than that original 300M years. It doesn't make sense that it would move so fast to a very weak gravitational force and sit in some theoretical perfect position thereafter.

We know nothing Mr Numbers.

An astrophysicist needs to invent a new type of maths which models three dimensional space with numerous mass gravity warps over time and then run the maths on a supercomputer which I believe may show the accumulation of gravity warps bends space outwards causing galaxies to move away from each other. It may be necessary to begin with star clusters which mysteriously seem to lose stars and drift apart. The constellation Ursa Major, the Great Bear, is an opened star cluster, all it’s stars are the same age and with similar chemistry, so what made a star cluster fly apart? surely they should spend eternity in each other’s orbits with perhaps one or two stars being hurled out resulting in the cluster tightening but that’s not what has happened, the stars are flying apart. This is where to find the answers to why galaxies are moving apart.

Very interesting stuff. However all the math falls apart at the point of origin so the big bang is not proven. It's still a theory, not a law. And the fact we can only account for 4% of energy/matter/gravitational forces suggests that we know so very little still about all the laws, forces, and particles at work in the Universe. We simply have a lot to learn and discover still.

TLDR: Dark matter is a theoretical magical matter that was invented over 100 years ago by some guy who applied newtons law while looking at a galaxy and realized that the outer most objects were not spinning around the galactic center as slow as orbital mechanics dictated. They did move at the right speed if the guy toke into account that the galaxy was heavier then he estimated the weight to be at. To him, fudging the numbers to get the right answer meant that the problem was that he was not seeing the missing matter instead of assuming the math to be wrong. Because maths in a era they had not gone to the moon yes was obviously not flawed, he theorized that there is somehow a dark, invisible form of matter. Modern dark matter believers say that over 70% of the universe matter is dark matter, how every they are not able to detect or prove that it exist. In essence dark matter is the modern version of "i dont understand lighting, therefore it is god who is angry". Currently there is a lot of scientist who are working with models to fix the equation that we use for gravity. In essence fixing the math instead of inventing something that clearly does not exist. Turns out, most of these works require just a minute adjustment, Sadly, the belief in dark matter which goes against the scientific principle is so encrusted now that to prove the dark matter believers wrong, their mathematical formula has to essentially also account for all the dumb shit they also say is the work of dark matter which is ridiculous since they basically have to prove the earth is round and as far as we know also show that the same proof explains why the mitochondria is the powerhouse of the cell, too things that as far as we know are unrelated except they have no proof. Basicaly, Dark matter believes are religious extremist with no proof for anything because its all theoretical since we are stuck on this planet.

Thank you. Professor Flintstone

18min in, I'm daydreaming, but what if dark energy/matter are like a sort of ocean, a form of matter that reacts in a similar way to water, as in well we're floating in something we don't understand, like a gas or a liquid. So then I wondered, isn't Hydrogen a funky particle, Hydrogen bonding is a big deal here on earth at least. Perhaps there is something more to hydrogen that we are unable to comprehend just yet with our current technology.

We observe from a tiny point in an obscure part of our galaxy, and fill in blanks with magic.

E=MC2? The energy, includes? Do you acknowledge the electric universe and plasma? If not you might get your pie graph.

the question is: what is dark physics? It seem to be devolving into mathematicians scrawling reams of formulas that very few understand. Many tap out ti infinities that are “renormalized”.

I'm pretty sure dark matter isn't some quantum thing. I think it's a more primordial information state intermediate to dark energy and quantum field related information. Also it is mostly a relic/initiator of the process that created the inflationary transition in the first place...

Three scientific lines without dark substances - 1. "First test of Verlinde's theory of Emergent Gravity using Weak Gravitational Lensing measurements" "Understanding galaxy rotation curves with Verlinde's emergent gravity" 2. "Testing the Strong Equivalence Principle: Detection of the External Field Effect in Rotationally Supported Galaxies" 3. "Galactic rotation curve and dark matter according to gravitomagnetism"

you wish.... we cant even define gravity unless we embrace the religion of scientism ...have fun in that cult

Dark Energy and Dark Matter May Be Anti Gravity. This drawing makes a case for anti gravity, not gravity, as the force that comes from acceleration.

There is no dark matter, the reason why the stars in the arm of the galaxy are all traveling at the same speed is because they are travelling in a straight line , linear path. .. The arm appears curved due to the gravitational lens effect. The second arm is a reflection due to gravitational mirroring from the gravitational lens. If the arm of stars were rotating then their speeds would increase towards the outside edge, but they do not. All the stars travel at the same speed, as if in a straight line. .. The influence on the stars positions is optically perceptual, from gravity lensing, and mirroring, and not physically gravitational. .. i.e. our galaxy is really just a comet shaped line of stars, swimming into a curvature of space, that lenses and mirrors... That curvature of space may be a source of great power... I think it's important for us to try to work out exactly what we are looking at when we look out into space. The gravitational curvature may have the power to gravitationally sling shot a craft to huge speeds, much more so than the weaker gravity of a planet .. Also there may be much to be learnt from studying the intense power of curved space... In short, ,, in my opinion,,,Dark matter doesn't exist, it's just an absence of straight space...

What if Dark Matter is on a nearby brane, but not the brane we're on composed of length, width, height and time? The string/brane guys say gravity can leak from one brane to another. So you can't find Dark Matter by searching through our brane using experimental apparatus. We actually would need to go somewhere else that had either more dimensions or different dimensions to find it.

Maybe inflation happens faster as you get away from the blackhole. The rate of inflation keeps the star systems moving at a faster pace the further they get from the galaxy. This is how galaxy systems are kept stable inspite of the gravitational and inflationary forces. How exactly do black holes interfere with the process of inflation?

It would be exremley interesting if it is a text in english languagae to the video. I am swedish and understand much better written english than a lot of strange dialects!

I though the blue parts on the cmb were the denser parts

I always thought that dark matter was alien poop that's what I learned in high school lol

Fantastic talk

I do not understand the thought that "we know dark matter exists". We know that there are some gravitational anomalies around and within normal matter bodies in space. Whether this is matter or not doesn´t seem to be proved as far as I know. Please explain.

If you've seen one lecture on dark matter, you've seen them all.

For the time being this comment 100% is true in terms of factual content. However. Some lectures are better than others.

Since your eyes detect photons you will never see dark matter. Its like hearing the color blue. Numerous detectors have detected left handed neutrinos, so we have detected dark matter. Right handed neutrinos are a likely canditate, but elude detectors, so far as I know.

Missing mass? Something that should be there but can not be uncovered? What changes if the speed of light is not a constant? Can you really age the universe by Doppler shift of light? Of course there are things we can not see, consistent in our reality; The air we breathe, the forces of gravity, magnetism, electricity, and more. Physics is the study of properties of matter. Can we uncover dark properties of our universe?

Dark matter is a Newtonian effect. You need to learn to listen better. ;-)

...and what is gravity, and what relationship between gravity and electromagnetism allows a UFO to fly ?

So is It a invisible solid..like would it move a human like wind?loll😭🙌🏼🌉💫

Just forgot to mention Neutrinos. They according to our ability to measure, have infinite speed, no mass no charge. Could it be, that we are not yet in the higher orbit of clear thinking. Would Tesla double coil help, by slowing neutrinos down and give them charge, so Power is in abundance. Am I talking to much?

Could dark energy and dark matter be a function of 4 dimensional space in a 3 dimensional plane. If energy = 4th dimensional space in a 3 dimensional plane. Basically Hawking radiation being a function of 4th dimensional space and all energy a function of Hawking radiation.

Occam's razor I think we are just wrong about the masslessness of photons and we are trying to find the mass of a spec of dust on a home bathroom scale we need too a better tool before we can find is tiny tiny tiny mass. Super ironic name for it if true
