capital, not Los Angeles or San Francisco) or Illinois (Springfield is the capital, not Chicago) and you could go on with Texas, Florida, etc… even when it comes to the United States as a whole you would think New York City or Los Angeles should be the capital and not Washington D.C, but it goes deeper than that, the United States is not centralized in one city like it happens to France/Paris, UK/London, Germany/Berlin and so on. As to why New York City is considered the capital of the world, it has been called that for the past 60 years. It is the home of the United Nations, Wall Street, New York Stock Exchange, lots of billionaires, people from all over the world live in the city. It’s basically the financial powerhouse of the world although London has been following closely for the past few years. Other reasons to consider New York the capital of world would be fashion, music, entertainment, tourism, etc.

This is completely correct. The Big Bang model suggests that all structures in the OHSAA 2023 State Baseball Championships Div I Div II Div III Div IV logo 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.)
