what is the fate of an open universe

3. If space has no curvature (i.e, it is flat), there is exactly enough mass to cause the expansion to stop, but only after an infinite amount of time. Open universe definition, a model of the universe in which the universe expands forever because there is not enough mass to counteract the expansion by means of gravitational attraction. One of the major reasons for studying the dark matter mystery is that the fate of the universe depends on how much dark matter there is in it. In a closed universe, gravity eventually stops the expansion of the universe, after which it starts to contract until all matter i … If the density is low enough, then the universe is open. The ultimate fate of the universe is a topic in physical cosmology, whose theoretical restrictions allow possible scenarios for the evolution and ultimate fate of the universe to be described and evaluated. This expansion will result in all matter becoming so far apart from each other that it can no longer … Two theories predict the fate of the universe.

Open Universe: In an open universe a negatively curved universe without dark energy would expand forever. 1. See more. This is known as an open universe. The fate of the universe, then, hinges on a very simple question: will the universe continue to expand, and how quickly? The first theory is the Open Universe Model, which explains that the expansion of the universe will never end. The ultimate fate of the closed universe is what we call Big - Crunh. 2. All matter eventually ends up in massive black holes. Stars will expand away from each other and galaxies effectively "evaporate." If < 1, the universe is open; if > 1, the universe is closed. Basically a heat death is where entropy (or disorder) increases in an isolated system (system = universe). Dark energy makes up about 70 percent of the current content of the Universe and thus holds the ultimate fate of our Universe. It is the ratio of the current density to the ``critical density'' described in the next paragraph. Individual stars die but their gas is recycled through the interstellar medium and new stars form in a never-ending process. The shape of the universe depends on its density. Since we now have some understanding of the problems involved, we will direct our attention throughout the rest of the book to the fate of the universe. What is the ultimate fate of an open universe? Thus, the universe has no bounds and will also expand forever, but with the rate of expansion gradually approaching zero … “The Open Boat” stresses that humans cannot change their fate, regardless of attempts to argue, threaten, or reason with the universe. If there's too much stuff, the expansion of the universe … In the popular astronomy magazines, you will probably see the mass density of the universe specified by the symbol `` ''. For example, the men try to use logic against fate, arguing they have come too close to the shore to die now. Several possible scenarios are … The universe would end in a heat death (known as Big Chill as well), or Big Rip.

This is called an open universe.
