has dark matter been proven yet?

Question

the u of az reserchers claim yes, but has their work passed peer review yet?

Answer 1

Claims were recently made that studies of the bullet nebula have prooved that dark matter exists - this is basically because the gravity is not concentrated where we can see the ordinary visible matter. The scientists assumed that the only thing that could account for the observations was dark matter.

But, scientist backing other theories (such as modified Newtonian dynamics) have since shown that their theories would also produce the observed results... so the existance of dark matter isn't certain.

Answer 2

Dark matter is matter whose existence can be "proved" by studying the gravitational effects of it on ordinary visible matter. In this "proof", the assumption involved is the validity of Newton's law of gravity. If you are a staunch believer of general theory of relativity, the existence of dark matter can be proved by the gravitational bending of light especially with regard to clusters of galaxies and by the velocity dispersion of galaxies.
If you don't believe that Newton's law of gravity is not valid for large distances you should consider MOND (modified Newtonian Dynamics) proposed by Milgrom in early 1980s. The problem with this theory is that there is no cosmology possible with this theory (at least till about 2 years back).
If you believe in Newton/Einstein, then you will have to prove the existence of at least some fundamental particles(WIMPS, primordial black holes, mass for 3 types of neutrinos etc) using the standard model.
So basically it is still an unresolved problem

Answer 3

Dark matter is essentially 'dark' which means that it cannot be proven practically or experimentally but its presence has been proven or at least thought of from solutions of mathematical equations regarding the universe. Dark matter is part of the total mass of the universe.

Answer 4

it is one of the more elegant properties of dark matter that its existance cannot be proven.

you can only indirectly prove it, by using it to explain an otherwise unexplainable phenomenon. you can even come up with the math to calculate it... but when all is said and done, there is no way of telling if not maybe something altogether different has caused the observed effects.

Answer 5

this is been shown that there is something obtainable including mass to the galaxies certain. you do not look to really comprehend the time period "darkish count number" regardless of the reality that. darkish would not communicate with the actual undeniable reality that this is darkish in colour. this is the former that technique of "darkish" as in mysterious and unknown. also count number would not communicate with the actual undeniable reality that it really is a actual substance, yet to the actual undeniable reality that it does look to exert a measurable gravitational effect, the picture of count number. So certain darkish count number has been shown. What precisely the darkish count number is regardless of the reality that is thoroughly unknown. As to black holes certain they have been shown. they have even been discovered. The large large black hollow on the middle of our galaxy has a measured mass of four million circumstances that of our solar. It also has a attractiveness, Sagittarius A* (suggested Saj-a-terr-e-us a celeb). The * suggested as celeb would not communicate with celeb as in vast ball of plasma. this is because Sgr A* develop into initially effortless in basic terms as a powerful radio source and * is the style used. we've also discovered really some different black holes obtainable. we've said large large black holes contained in the middle of really a lot each and every galaxy we've regarded at. we've also been in a position to perceive smaller stellar mass black holes the following in our personal galaxy, which comprise V4641 Sagittarii it really is the nearest effortless black hollow to the Earth. We used to imagine it develop into "in basic terms" about a million,600 gentle years away yet we now imagine it really is a lot farther away than that.

Answer 6

My question is? Who is privileged to this finding or is there a special peer group made up to review everything first?

Answer 7

it has not yet proven but dersm some predictions and studies dat d dark matter exist. dey r detecting it using xrays (radiation). another one is d disappearance of d stellar neighbors w/c dey bliv dat d black holes qre lrgely involve....
