(split) What is dark matter?

It is an other fudge factor that the equation need to make it to look good .

I'm not sure about adding our own ideas. Some Galaxies have planets that orbit so fast that the planets should fly out of the Galaxy. That's an observation. Einstein used a cosmological constant that has both inward forces, and outward forces working together. This is a formula that needs a new approach.

Like I said, this isn't the right room to post our own ideas.

I'd be very interested to see where this leads. Can you talk about it in the alternate theories section?

 

Yes, that is the right place. You should start the thread, I don't want to push my theory on people.

 

Imagine dark matter as a type of place where all matter has been removed except for the substance that actually holds everything together, like an invisible glue sort of. The glue can bend, wrinkle and stretch to allow the particles that exist within it to move about.

 

Yea a bunch of Higgs particles , It it us a fair idea we can nit find them either

 

I have never heard that - could you cite a source for that?

 

I've looked way back, it was the first time I ever heard of dark Matter. I suppose the internet has eaten it.

 

There are some "alternate theories" that account for dark matter!

 

Dark matter is negative mass (energy)

In my opinion,
Dark matter is negative mass (energy). This is hypothesis.


[ Centripetal force effect in the galaxy from dark matter(negative mass) halo out of the galaxy ]

If the negative mass is disposed at the outline, the test mass vibrates, and a kind of restoring force (This corresponds to the centripetal force when considering rotation of the galaxy) exists.

This suggests that the halo, dark matter (negative mass) of the external Galaxy could get additional effects of centripetal force to the inner Galaxy.

fig12. Negative mass effect on arms of galaxy. The actual observed spiral galaxy is on the left. Since repulsive effects occur between negative masses in Newton’s dynamics, negative masses will be distributed all over space because it cannot form large mass structures like stars. Negative mass within the galaxy is cancelled out by attraction from large positive mass during the galaxy formation process. Furthermore, the space, other that the galaxy, will maintain the distribution state of negative mass.

1) if we assume that the white empty space is full with negative mass and positive mass at the same density
white empty space(0) = (+mc^2) + (-mc^2) =0

2) here negative mass is uniformly distributed over the whole area, so the effect of negative mass on mass m is 0. Remaining positive mass is distributed over the white area on the left at the density of negative mass, and

3) the gravity that uniformly distributed positive mass(same density to the negative mass density) works on positive mass m place on radius r is worked only by the distribution of mass within radius r.- Shell Theorem


The gravitational effect from negative mass, which functions at mass m is equal to the gravitational effect from positive mass within radius r.

Therefore, the effect of negative mass that remains out of galaxy without being offset can make it approximate to the gravity generated by the distribution of positive mass within the radius R in galaxy

Yes, I think somebody already came up with this...

I think dark matter is a theory for that something extra, which is needed to explain certain anomalies in consensus theory. As far as I know, it has never been seen in reality but is needed to keep the base theory valid. It is the image of a bandaid that needs to be fabricated to make the boo-boo better.

As an analogy, we come up with the theory that says males car drivers are better than female drivers. This is accepted as fact for many years. But based on data collected during that time, we notice this does not always add up. To keep the original theory we might need to add a mystery osmotic force that transfers from male to female causing this data anomaly. We will call it the invisible driver force which we cannot measure yet. Can anyone prove otherwise?

 

I will soon. Once I have my Galaxy model up, and running. The negative mass idea is the way to go IMO. It sure fixes a lot of things.

 

Oompa Loompa's also make thing really easy they too fix alot of things. Can't explain something? No problem, it is something that the Oompa Loompa's are involved in. No math, no questions - easy!

 

Admit hyperbolic black hole galactic gravitational field as mere tentative postulate

Admit the hyperbolic black hole galactic gravitational field (HBHF) as a mere tentative postulate that explains Dark Matter

I have shown that it is expedient and practical to admit the hyperbolic black hole galactic gravitational field (HBHF) as a postulate – that is, as a mere tentative logical premise. There are several ways in which it could be confirmed as a contender for a place in the cosmological pantheon of physical “law”. If it could be seen as a real cosmic rule, every single one of the phenomena that are now ascribed to “Dark Matter” can be more parsimoniously charged to the HBHF.

This is also because, by extension, the HBHF can be used to characterize the hyper-excited “inflaton particle” in the false vacuum of the ultra-high energy “inflaton field” that is supposed to have sprung into existence as a probabilistic quantum fluctuation. It offers a new way to forge another link between quantum dynamics and relativity theory.

When enough such links are made, we shall obtain a quantum theory of relativity without having to tolerate the putative overbearing “grand unified theories” or “theories of everything” like superstring theory or quantum loop gravity. These seem to offer no advantage other than the grandeur of hyper-complexity and the safe haven of unfalsifiability. In other words, the HBHF might allow theorists to “get real”. So, it is practical and expedient to admit the HBHF as just such a postulate.

The HBHF, if it can be allowed, would further reinforce Inflation Theory by providing a mechanism for the transition of the excited inflaton HBHF particle/field to a “ground state” inverse square gravitational field. It implies how potential energy in the inflaton field might have powered inflation and how it may now be powering “reinflation”, the accelerating Hubble expansion of the universe in the current epoch. It would seem to require endorsement of the “Many Worlds” interpretation of quantum mechanics/dynamics because the HBHF must have pre-existed inflation in a sort of “metatime” in a “multiverse”. But, this is implied by Alan Guth’s inflation hypothesis anyway. And then, if the universe was once a quantum entity, then it still is – with profound implications and more opportunities to forge links with GR.

Incidentally, the HBHF can certainly be admitted according to common interpretations of some theorems of general relativity if spacetime, in the moments before inflation, was indeed regarded as “flat”. That is, the HBHF can certainly be allowed by GR if the HBHF inflaton field is restricted to two dimensions. This gives a new twist to inflation. It may mean that inflation involved “unpacking” our spatially 3-D universe from a more compactified 2-D version.

And then, the deep interior of black holes at their singularities (as physical realities) might be viewed as recompactifications of spacetime – reconvolutions to a strictly 2-D format wherein the HBHF can persist with no contradiction to conventional interpretations of GR. Then, in our multiverse, the galactic 2-D HBHF multiple sibling set might define orbital planes for each and every entity in its gravitational purview.

That this galactic field must be defined as a disk shaped oblate spheroid means that its tidal influence on the central super-massive Black Hole (SMBH) must be concentrated in the plane of the galaxy. The mass of the disk may be thousands of times the mass of the SMBH so, its (mutual) effects on the SMBH are very substantial. Thus, Einstein’s theory of the relativistic non-symmetric gravitational field must be used to characterize it and that of the SMBH. Nobody has ever done this. And Birkhoff’s Theorem or its congeners simply do not apply to any real BHs.

Simple geometry is used to define radiant flux and other quantities that are posited to emanate from a point source. An imaginary sphere is constructed around the source. An infinitesimally small area is defined on the surface of this sphere. Then the flux, quantity of lines of force or light lines, through this fractional area must be proportional to 1/r^2 because the total area of a sphere is proportional to 1/r^2 and the spherical enclosure envelopes all the flux. Using this definition to prove that gravity must be an inverse square (1/r^2) phenomenon uses circular reasoning because it assumes as a premise that which is to be proven (it begs the question).

What if the source, even though it is a point, is assumed to be enclosed by an infinitesimally small space that is a very oblate spheroid by virtue of its extremely rapid rotation? What if this is the ultimate source, in fact. Then, what if this flux emission pattern is also very strongly oblately spheroidal? In addition, what if this flux was influenced by relativistic “frame dragging” and “thirring”? Also, what if the gravitational tidal influence of a galactic disk would also influence this spheroid to be even more oblate? The gravitational field of the disk must be perfectly coaxial and concurrent with the field of the SMBH. Its field must perfectly superpose. Then, the combined field must be treated in order to determine if there could be a hyperbolic field component. But, this combined field is even more “non-symmetric” and even more difficult to handle with GR, except by Einstein’s non-symmetric field theory, which has never been done. So, it is really impossible to prove by appeal to any theory or principle whatever whether the hyperbolic gravitational field is impossible. But, it is possible to appeal to strong geometric principles to argue that, indeed, it is possible.


I need a collaborator ! ! !

It isn't circular reasoning. I'm sorry if you still don't understanding it but you aren't going to get a competent physicist to collaborate with you if you're openly dishonest like that.

Actually, the effect DM has on light(via it's gravity)has been documented. DM exists, the thing we don't know is what it consists of. It's only interaction with the Universe(that we know of now)is it's gravity. It is what keeps our galaxies from flying apart, it is probably what caused the gathering of material that formed galaxies in the first place, it is the driving force that causes cluster of galaxies to be gravitationally bound and it probably served as the seeds for the super massive black holes that created the galaxies. It constitutes around 25% of the total mass of the Universe(visible objects are about 4%, Dark Energy about 70%). Not a band aide at all, just something we don't thoroughly understand yet.

Indeed. Many cosmologists now propose/speculate that DM is a contributing component in the formation of galactic accretion clouds/discs.
