If Darth Vader had study galactic phylogenesis , he might never have think the power of the dark could hold out clean ’s force . A new explanation for puzzling astronomical observations relies on the force play provided by photons of light source having scattered dark matter during the formation of the Milky Way .
Recently , astronomers have become disoblige by the modest satellite galax around our own . For one , there are fewer of them than our models of galaxy organisation hint . For another , their locations and movementsdon’t seem to be random , as these same model predict .
InThe Monthly Notices of the Royal Astronomical Society , a squad direct by Dr. Celine Boehm of Durham University note that these example of satellite beetleweed organisation bank on dark matter to provide a gravitational seed attract the flatulence which finally become stars . These models depend on glum thing ’s soberness impact the more familiar particle , but exclude or ignore other form of interaction .
Since we stilldon’t really knowwhatdark issue is , this is not surprising . We ’re not certain whether it interact with the seeable macrocosm in any other fashion , but we are surefooted that if such interactions exist at all they are n’t strong ; thus why they ’re consideredWeakly Interacting Massive Particles(WIMPs ) .
However , Boehm tried mold what would happen if neutrinos and photon of spark apply a force to dark matter , stimulate the dark matter particles to dot . The final result is few spots of topic clumped enough to start attract gasoline . “ By tune the strength of the strewing of corpuscle , we change the number of small galaxies , which allow us learn more about the physic of dark matter and how it might interact with other particles in the cosmos , ” Boehm sound out .
Co - author Dr. Carlton Baugh , also from Durham University , say our cosmological model , “ can explain how most of the universe of discourse looks , except in our own backyard where it fails miserably . "
However , with the fashion model including just a low amount of fundamental interaction between dark and ordinary matter Baugh says , “ We can give our cosmic vicinity a makeover and we see a noteworthy step-down in the number of beetleweed around us compared with what we originally thought . " With coloured matter thought to overbalance the particle we can see by a factor of more than five , understanding it comfortably is hugely authoritative to know how the universe works .
