‘The Mariana Trench or Marianas Trench is the deepest part of the world's oceans. It is located in the western Pacific Ocean, an average of 200 kilometres (124 mi) to the east of the Mariana Islands, in the Western Pacific East of Philippines.’ This part of the ocean alongside many others located at various places, have been explored. There is nothing anywhere in oceans comparable with what wonders exist along depths of the interstellar and intergalactic space, in the deep reaches of the physical universe.
The answer to what wonders may exist in the apparently unfathomable space however do not lie not across vast distances of space, but inside an ocean of another kind, within the even more unfathomable recesses of matter, that everything is made of, at the heart of atom, the frontier for exploration.
‘The Large Hadron Collider (LHC) is the world's largest and most powerful particle collider, the most complex experimental facility ever built, and the largest single machine in the world, that was built by the European Organization for Nuclear Research (CERN) between 1998 and 2008.’ The LHC is to do just what a deep-submergence vehicle (DSV) would in a regular ocean, or a spaceship would traversing universal space, i.e. to explore the oceans that exist at the heart of matter.
