The large-scale structure of the universe—the gigantic, hierarchical cosmic web of structures bound by gravity—is mostly made up of dark matter. The growth of the large-scale structure, from individual galaxies to galaxy ...
For the first time, scientists have observed antimatter particles—the mysterious twins of the visible matter all around us—falling downwards due to the effect of gravity, Europe's physics lab CERN announced on Wednesday.
