Dark matter was first suggested to explicate the weird rotation of galaxies , yet   almost 50 eld afterwards , we still have no clue if it exists or what it is . Over the last 15 age , astronomers have trust more and more on pretense to see   if the theoretical forecasting of dark matter actually do match the observation .

And the latest one , published inPhysical Review Letters , strengthens the perspective of dark topic above alternative explanations . The simulation was conducted by an international team of cosmologist and head by Durham University . It usher that the presence of dark issue connects the sizing and revolution speed of galaxies to their brightness , just as seen in observations .

“ This figure out a long - endure problem that has troubled the dark subject model for over a decade , " lead writer Aaron Ludlow said in astatement . " The dark matter surmise remains the main explanation for the source of the gravity that binds galaxies . Although the molecule are hard to detect , physicist must hang on . "

One of the late challenges to dark subject has been the find of amass discrepancy acceleration intercourse . This empiric link connected the gravitational quickening of the Galax urceolata to the mass of seeable issue , which makes stars , planets , us , narwhals , etc .

There are other relationships that   have been hard to procreate in simulations as well . While dynamic mass and the mickle of all the stars in a galaxy is well correlated , simulations using dark matter have not been able-bodied to reproduce the correlational statistics . Scientists have face for novel theory , such as   theModified Newtonian Dynamics , that   do a good job at explaining   and predicting these relationships . Well , until now .

This simulation is more refined than previous 1 , with   the squad able to reproduce beetleweed of dissimilar sizes and how they develop over the form of the universe . The new figurer model demonstrate that dark matter can easily explain what ’s seen out there in the cosmos .

Dark matter is still as deep as ever , but it lives to oppose another day as the best explanation of what we see ( and do n’t see ) in the universe .
