Sentences with phrase «matter filaments»
The phrase "matter filaments" refers to thin threads or strands made up of matter, such as particles or substances. It suggests the presence of these threads connecting or forming a structure. Full definition
«By using this technique, we're not only able to see that these dark matter filaments in the universe exist, we're able to see the extent to which these filaments connect galaxies together,» study co-author Seth Epps, a master's student at the University of Waterloo at the time, said in the statement.
