When a "particle" is spread out, like a densification of "aether," covering a wide area, like a waveform in a medium, and this is its ("particle's") coarsest possible state, then how could it be measured ? It is present; it is "dark", but unmeasurable (like "aether"). It is easier to say that: "It does not exist" (AS PARTICLE). It is a local quality of space rather than a particle. If, for example, we imagine that the "cosmological constant" has a local variation or transformation, how could it be measured ?

Dark matter is dilated mass. G.R predicts dilation not singularities. In the 1939 journal "Annals of Mathematics" Einstein wrote - "The essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (Schwarzchild was the first to raise the issue of G.R. predicting singularities) do not exist in physical reality. Although the theory given here treats only clusters (star clusters) whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light." He was referring to the phenomenon of dilation (sometimes called gamma or y) mass that is dilated is smeared through spacetime relative to an outside observer. It's the phenomenon behind the phrase "mass becomes infinite at the speed of light". A graph illustrates its squared nature, dilation increases at an exponential rate the closer you get to the speed of light. A "time dilation" graph illustrates the same phenomenon, it's not just time that gets dilated. Dilation will occur wherever there is an astronomical quantity of mass because high mass means high momentum. There is no singularity/black hole at the center of our galaxy. It can be inferred mathematically that dilation is occurring there. In other words that mass is all around us. This is the explanation for galaxy rotation curves. The "missing mass" is dilated mass. Dilation does not occur in galaxies with low mass centers because they do not have enough mass to achieve relativistic velocities. To date, 6 very low mass galaxies including NGC 1052-DF2 and DF4 have been confirmed to show no signs of dark matter. This also explains why all planets and all binary stars have normal rotation rates, not 3 times normal. The concept of singularities is preventing clarity in astronomy. Einstein is known to have repeatedly said that they cannot exist. Nobody believed in them when he was alive including Plank, Bohr, Schrodinger, Dirac, Heisenberg, Feynman etc.

@@shawns0762 Interesting, I have always thought that as well. "matter cannot be concentrated arbitrarily" Singularities are a result of the mathematics used to solve the equations. If a very large black hole got moving fast enough, perhaps space might rip apart. Anyway this video is interesting. Space is "something", and time as we consider it, is also somewhat an artifact. You can't measure it without expending energy. Energy state transitions have to propel everything.

Title of the video has a question mark (?) Thus the answer to the question is always: NO.

I'm glad I wasn't the only one confused by those headlines; it took me a while to figure out what "ghost particles" was referring to.

I saw a video talking about "rogue" planets that are wondering around the galaxy (and presumably all galaxies). It was postulated that there are a lot more of these "dark" planets out there then we thought and this could even be the source of dark matter. the idea was that if there were enough planets without stars to orbit around, they would be very dark and hard/impossible to detect, but would add up to a large gravitational force. did you ever think of doing a video on this idea? thanks Sabine for all the hard work on your videos. i really enjoy them.

The point with dark matter is that what we observe is that it has a gravitational effect, but it doesn't interact with electromagnetism or weak and strong nuclear. If there were just many planets that we can't see, we indeed would see these gravitational effects, but we would also see more effects appart from gravity. That is all the point with dark matter and its difference with normal matter, it is not just normal matter that is in a dark place.

Sabine, you could write an excellent guide to writing science articles!

I was fully expecting you to call bullsh*t at first, just on the basis of the headline of the BBC article, so it was interesting to discover what a reasonable experiment it really is and WHY it's a good one, and to realize it was merely the BBC that was full of it. So much bad science writing in the world!You're a gem amongst so much drek.

What if dark matter is the fabric of the universe, the quantum foam, or the ether, or whatever you want to call it? Fabric bunches and if more is gathered in a spot we would expect to see stars gathering more in these gathered folds, you know like that supercluster.

the experiments have been done. the papers written. the results ignored for more costly endeavors. good job.

It seems to me the Dark Matter is the Ether. When atoms come together their Electron Orbital Shells come together and form Electron Valance Shells. When atoms come together and form a matter like earth, then all the Electron Valance Shells come together to form a Massively Multilayered Electron Valance Shell. The MMEVS is a pressure gradient and generates a buoyancy force which we call gravitational field. The MMEVS field is a field which is made up of electric field AND magnetic field shells. Through this field, light passes as radiation waves. Gravity-wise, it is same with the moon and the sun and any other matter which exists in this universe and beyond. The Ether is the fundamental field and matters are created from the Ether, I think as cavitation bubbles. I hope it helps.😅

Hello, Sabine. Great video as always! I am watching your channel because I like your "no bullshit" method))) I have offtopic question, i am a simple person without deep knowledge in physics or math, so I wanted to ask real professor about this. Sir Roger Penrose has his CCC theory, I am amazed by it and i think that I understand it's abstract principle. But to me it looks like everybody in scientific world ignoring it. So my question is why? Is it because there is some holes or errors in that theory and everybody do not want to upset Sir Roger? Or there is some other reason? Please explain it to me because it's bothering me for years.

I do not think Dark Matter is a particle what can be found in an accelerator. I'm more thinking toward that dark matter is an effect of the moving space-time. In principle frame dragging. More over, I think the "empty" space has mass and momentum too and it is very "elastic" (gravity wave)...

Dark matter travels faster than the speed of light. You cannot catch it because it travels faster than light can bounce to detect. You will need a gravitational detector to detect dark matter and how fast it is traveling. LIGO plus machine can do it.

Sounds as if Star Trek's Transporter could become a scientific reality someday.

One big problem with this approach is that if we are wrong about how “weakly” they interact, and they end up being highly attracted to one another (or to other particles), creating a highly concentrated area of them could be extremely dangerous. Imagine if these particles are actually those responsible for singularity-like behavior, and we’re about to create a room full of them.

Big bang is starting origin, we are p1 of x positions, the observable universe p2 of x positions. Under this model, constant expanse is present. Point to be made, by understanding which directions from us a local observer, expand, faster or slower, we could determine our earthly location in accordance to the big bang. This model also shows how further points appear to be expanding away from origin at greater and increasing speeds. Reason being expanse from X to X2 is constant , however the compounding expanse of each point, means X and X^n+1, the later point will be moving away at the constant plus all the constants between points. All points expand constant, but to the observer, further points move away with greater speed than the observed local constant.
