Dark matter - alternative

My Theory
'''''''''''''''''''''

Dark matter is thought to exist only because of unpresidented acceleration of lightmatteron the outskirts of galaxies. As this lightmatter on the outskirts is accelerating faster than it should be given the light matter visible there is thought a larger gravitational pull from the centre coming from a larger mass, though not visually possible. This speculation is given the name darkmatter, like "black holes", for matter that physically should be there for einsteins, ect. equations to fit in place and to be proved by ESA, "hopefully" soon .

But could ...

As there is more space and less matter on the outskirts of galaxies, less gravitaional pull is given to matter particles. This maybe allows matter and antimatter to collide more willingly as gravitational pull is less on the matter. This could arise that there is a point on the outskirts of galaxies where this excess acceleration occurs due to the attraction between antiparticles is being greater than the gravitaional pull from matter.
As these antiparticles anhialate(sp.), a great deal of enrgy is given off in the form of photons. Could this background energy creation be the reason.
This type of interaction force is a simular idea already expressed in chemistry. Like hydrogen bonding being very strong in proximity but as you are drawn away from it even a small van der vaals force can be overwhelming, if nearer (like antimatter attraction).


Just an alternative, as I have not seen any others in a long time, most probably my entire life.

I thought Dark Matter was just regular matter that didn't reflect light that we can see at the present time as its wavelength is too small to measure directly.

i think its said that dark matter is the force expanding the universe and at the same time keeping all galaxies in unison. with its reverse gravitational effect it keeps light matter intact, according to einstien our galaxies should have broken apart since they are moving so fast. dark matter largely consists of nutrinos and massive particles, things we do not fully understand.

Dark energy, no? Dark energy is whats thought to be driving the expansion. Its 'predicted' in einsteins theories, as far as I understand it, out of that 'cosmological constant' bit, which he thought was a mistake (but I think I am maybe conflating some ideas there).

and at the same time keeping all galaxies in unison.

What unison?

I think that there is, along with Matter, Energy, Dark Matter, and Dark Energy, there has also been a postulated "Quintessence", a fifth major portion of the universe, thats supposed to account for some other 'high level' cosmic physics problems. Or something.

Does exists some continuity with dark energy and teleportation? My informant said something...

Quantum 'teleportation' is merely 'quantumly entangling' two particles. This results in changes in one instantly showing up in another, not actual 'teleportation', ie destruction at one site and reformation at another.

I don't know of it having anythign to do with dark matter or dark energy.

i was under the impression that this is correct, and that dark matter is what would be responsable for the possible contracting of the uiniverse (the big crunch) if the universe was a closed, as opposed to open universe

"closed" universe being one that will eventually collapse under its own gravity due to there not being enough energy released in the enitial "big bang", and "open"universe being one in which there was enough energy for the universe to break free of its own gravity and continue to expand forever.

if i have it wrong, someone please correct me

Urn, Dark energy is what is driving the expansion as has been theorized as of late. Dark Matter is nothing but regular matter that doesn't reflect light that we can see I believe. DM Is mostly microscopic-nanoscopic cosmic dust.

Regarding Dark Matter it probably can't be used as a energy because we don't totaly know what it is.

As for Dark Energy we don't even have proof that it exists.

Maybe in the future we will be able to figure it all out for sure.

thats what i was trying to get at...(and i was agreeing with Nygdan about dark energy)


i was under the impression that dark matter (matter we cant visually account for) is what could account for the extra mass needed to make the universe a closed universe

i believe they are now theorizing that the universe is actually an open one as opposed to closed...

Yeah thats through String or M- Theory I believe. Has something to do with Gravitons "floating" off of our Brane as they are believed to be closed loops so they only interact with our Brane very weakly for some reason. Just a theory though so It could be proven false.

There is a whacky third alternative. There is an idea that if the rate of expansion keeps increasing, I mean really gets high, then the fabric of space-time itself rips apart, and even rips apart 'according to scale', with huge divisions of the universe beginging, then smaller level order rips, all the way down to individual atoms and fundamental particles.

Very speculative at this point tho.

Yes there is... Einstein's "cosmological constant".
There's something which accelerates expansion, it has been detected in last few years.

Sardion, why do you claim that it is mostly dust? Surely there is not enough dust to account for the powerful gravitational effect that "dark matter" exerts and which keeps a galaxy from scattering. A more reasonable explanation is that there are millions of "brown stars", stars that have spent all their fuel and are the huge, cold remains of their previous glowing selves, and are maybe just as numerous as glowing stars, or even more so. It is not surprising that we do not see this vast accumulation of dead stars. How visible can a brown object on a black background be?

Furthermore, our Sun could have a companion that is one of these brown stars, born of the same mother star, still going around in an orbit so large that it approaches the Solar System every several thousand years. It might sneak up on us, and when it will be near enough so that sunlight will finally render it visible, we will surely go into a planetary panic. The strong pull of the thing might tilt the Earth axis even more, or it might have the opposite effect, that is, straighten the axis, so that the yearly season cycle will be no more, and we will have a milder climate throughout the planet, a permanent springtime. Whatever the case, the adjustment will trigger thousands of earthquakes everywhere. At the very least, the stock exchanges will come crashing down, if not the buildings.
