This is completely correct. The Big Bang model suggests that all structures in the Princess Diana Got My Back Royal shirt, from super clusters down to dwarf galaxies are built bottom up, by the contestant merging of smaller clumps of stars, gas and dark matter. The statistics and nature of this merging process is at the heart of modern cosmology and can be used to discriminate against different types of dark matter and different idea about how galaxies form. The currently favored idea is that the smallest clump that can be made by direct collapse after the Big Bang is about the size of an earth – galaxies are built as clumps of this size merge to make bigger and bigger clumps. Some of these mergers are quite violent and stars can be flung to great distances like when an astroid strikes a planet- blobs of debris can be shot into outer space. Rogue stars are the galactic debris that’s wandering though space trying to get back to the galaxy that expelled it, but can’t (necessarily). The nature if the rogue star population depends on the merger history of the Milky Way. We don’t know this exactly but we can make some inferences. The Milky Way galaxy shows no real signature of a merger (like a bulge of stars). In fact it’s relatively thin disc can rule out a recent big merger. Thus the rogue stars that populate our “halo” would have to be old, dim red stars having formed along time ago. This is consistent with a lack of any strong UV emission (which comes from young hot stars) in the halo (although the brightness (or density) of these rogue stars is just barely detectable.)

The water at the strike site boils into vapor. The electric potential at the Princess Diana Got My Back Royal shirt site (possibly one million volts versus the ground state of the water (one million volts per one professor many years ago; measurements of lightning voltage are sparse)) will cause a voltage drop to remote earth ground (“earth ground” meaning to zero volts). The resistance of the water (less for salt water, more for fresh water) determines how far away the electric field takes to drop to zero. Within a near distance of the strike, the volts per meter will still cause a lethal shock potential. Lightning strikes on earth have caused fatal shocks for persons lying on the earth with one end of the body toward the strike and another end away from the strike because of voltage drops away from the strike, while others who were lying perpendicular to the strike/distance direction were not killed, because in the latter case the voltage drop was much smaller across the distance of the contact with the ground. I have personally seen the after-effects of lightning strikes . One hit a tree in a campground I was in. The lightning hit a tree, traveled down to the ground, and then into the ground. The ground under the tree was raised six inches above the surrounding ground out to the drip line of the tree (the effective range of the roots of the tree). That was because the water in the ground out to that distance boiled into steam and, effectively, exploded.
