yeah i did,i discussed it on net with mesa guys and science teacher and surfing net but lateron i discovered that what result i come to same appeared before also the same was tried and were able to made it but that thing break up because of excessive friction gonk gonk gonk gonk gonk

about theories
yes,i have opposed some, i like going in deep which not many people likes some dont like ging in this discussion ,some forums are shity when they talk about such

there are some universe theories i read ,contradicting but someway to same

stephen hawkins books are quite good

right now with the word field i have many things in mind
quantum filed theory
electromagnetic field
energy field well its called so in quantum physics it includes electromagnetic field

yes something is missing which is binding but in the universe what that something is apart from gravity?
what can a gas can attract a gas and plasma to plasma gravity?that missing gravity is coming from to what we dont know and named as dark matter

fundamental particles
now what should i say, in string theory it is believed that the gravitational force is because of gravitons which we haven't discovered yet (wait for LHC experiment )
higgs and many are yet to be discovered but postulated before

well i believe in dark matter

You know what one of my friends told me? She said that her friends like my horror stories. I can't believe it! SHe has a lot of friends too. I didn't know so many would like them. Even if I'm a novice.

i ask you something


suppose for a galaxy it requires x amount of gravity


but we were able to find only 1/5x that means if galaxy really exists it means there has to be something which exert gravitational pull


you know that dark matter is also has been classified





torically, three categories of nonbaryonic dark matter have been postulated:





     Hot dark matter - nonbaryonic particles that move ultrarelativistically


     Warm dark matter - nonbaryonic particles that move relativistically


     Cold dark matter - nonbaryonic particles that move non-relativistically











PROOF


[code]The first person to provide evidence and infer the existence of a phenomenon that has come to be called "dark matter" was Swiss astrophysicist Fritz Zwicky, of the California Institute of Technology in 1933. He applied the virial theorem to the Coma cluster of galaxies and obtained evidence of unseen mass. Zwicky estimated the cluster's total mass based on the motions of galaxies near its edge. When he compared this mass estimate to one based on the number of galaxies and total brightness of the cluster, he found that there was about 400 times more mass than expected. The gravity of the visible galaxies in the cluster would be far too small for such fast orbits, so something extra was required. This is known as the "missing mass problem". Based on these conclusions, Zwicky inferred that there must be some non-visible form of matter which would provide enough of the mass and gravity to hold the cluster together.





Much of the evidence for dark matter comes from the study of the motions of galaxies. Many of these appear to be fairly uniform, so by the virial theorem the total kinetic energy should be half the total gravitational binding energy of the galaxies. Experimentally, however, the total kinetic energy is found to be much greater: in particular, assuming the gravitational mass is due to only the visible matter of the galaxy, stars far from the center of galaxies have much higher velocities than predicted by the virial theorem. Galactic rotation curves, which illustrate the velocity of rotation versus the distance from the galactic center, cannot be explained by only the visible matter. Assuming that the visible material makes up only a small part of the cluster is the most straightforward way of accounting for this. Galaxies show signs of being composed largely of a roughly spherically symmetric, centrally concentrated halo of dark matter with the visible matter concentrated in a disc at the center. Low surface brightness dwarf galaxies are important sources of information for studying dark matter, as they have an uncommonly low ratio of visible matter to dark matter, and have few bright stars at the center which would otherwise impair observations of the rotation curve of outlying stars.





Gravitational lensing observations of galaxy clusters allow direct estimates of the gravitational mass based on its effect on light from background galaxies. In clusters such as Abell 1689, lensing observations confirm the presence of considerably more mass than is indicated by the clusters' light alone. In the Bullet Cluster, lensing observations show that much of the lensing mass is separated from the X-ray-emitting baryonic mass.[/code]








i know that you know about gravitational lensing ,rememember the black hole? yes the gravitational lensing,same happens here due to dark matter exerting high gravity,and the light being affected by gravity get its path changes leads to gravitational lensing the same one as in case of blackhole





so how you gonna make difference? well black hole also emit a lot remember the hawkin radiation we discussed and real and virtual particles it radiates with heat, takes these factors in consideration 








another quote from pedia


[code][b]Detection of dark matter[/b]





These cosmological models predict that if WIMPs are what make up dark matter, trillions must pass through the Earth each second. Despite a number

see by dark matter what we really mean is that that matter which we do not react to the normal matter or electrical properties in space
it was found when we used the formula to calculate the weight of the galaxy and found it to be much lower then what it is,even after taking radiation into consideration.the deviation was of 5 times, now look it other way, you know that the space is expanding (i would not like to add the role being played by dark energy over here for simplicity) so galaxies are moving away but to keep a system a system that is being it together it needs some kind of attractive power to which we may call gravity ,so there must be 5 times of more matter which we would need to keep all such in contact and to this invisible matter which doesn't react with normal matter we call dark matter

i think i cleared the first point "it can not be measured" it can be measured by the gravity required less gravity of substance we can see

how are you saying light and dark matter are opposite,there isnt much relation

light do not create or exert gravitational pull but dark matter does (light doesnt lead to dark energy or anti gravity)
light is categorized under photons which is one of the known particle which is not the composition of darkmatter PHOTONS CAN BE MEASURED
dark matter do not react with normal matter but light does
gravity by dark matter can affect the path of the photons which create light but light can not change the path of dark matter
the only simlarity i would talk about is BOTH HAVE THE SAME SPEED IN SPACE that is to say speed of gravity = speed of light (the rate at which the gravity waves travels is equal to the rate of speed of light which is a radiation) {proved by Einstein}

wave particle duality - combining both the waves and particles and it is used in many case and i think the first one was light in itself
thats why i said they both are important,youjust cant ignore one,the light you are talking is integration of these 2
when an electron in an atom is moved from the shell due to excessive energy its electron(s) goes to higher frequency and then it come backs to its normall position and during this process photons are released
