This will happen only after an extremely long time because first, some (less than 0.1%) [73] matter will collapse into black holes, which will then evaporate extremely slowly via Hawking radiation. The universe in this scenario will cease to be able to support life much earlier than this, after some 10 14 years or so, when star formation ceases.
Recent space exploration has proceeded, to some extent in worldwide cooperation, the high point of which was the construction and operation of the International Space Station (ISS). At the same time, the international space race between smaller space powers since the end of the 20th century can be considered the foundation and expansion of ...

In 1978 and 1979, Robert Brout, François Englert and Edgard Gunzig suggested that the universe could originate from a fluctuation of Minkowski space which would be followed by a period in which the geometry would resemble De Sitter space. This initial period would then evolve into the standard expanding universe.
