How dark matter could help foster life on alien worlds

dour affair might not just making the universe of discourse more massive than it should be , it might also be making the universe more thickly settled than it should be . Find out how .

One of the forces that countenance scientists know that dark matter is out there is gravity . scientist observed galaxies ’ gravitational interations with other galaxies , and find that they were behave as though they had much more mass than was visible . Since sullen topic exerts a gravitational drag , it has to be involve by gravity as well . Scientists believe that sullen subject particles would orbit a galaxy ’s center of mass . As they orbited , they would pass on through planets , and some particles would clash with the planets ’ atoms . Dark matter would build up inside the planet , adding to its passel and travel toward its gist . There they could attain other dark matter particles and annihilate , releasing Energy Department and heating the satellite .

Earth would n’t be a prospect for the process , since it ’s trapped in a backwater part of the Milky Way , forth from the center of the wandflower . satellite closer to the meat could feel dark topic ’s heating effect , even if they did n’t get energy from a nearby star . It ’s possible that this heat could even be enough to sustain life on these planets . decently now , though , the estimation remains firm an idea , since no current scope could find a dark major planet float in blank 26,000 light-headed years aside . Looks like the other planet would have to find earth .
