Economic-historian living in Stockholm, Sweden. Just passing by on this planet Earth in an ordinary solar system in the Milky Way galaxy. One of more than 54 galaxies in a local group which is part of the Virgo Supercluster with some 2000 galaxies. The Universe is extremely strange because we don't know what caused Big Bang and we don't know about dark matter and dark energy which surround us all. The matter we can observe represents some 4-5% of the Universe.
