Closed or open universe
WebFeb 10, 2024 · If the universe's density is great enough for its gravity to overcome the force of expansion, then the universe will curl into a ball. This is known as the closed model, … WebOpen Universe: In an open universe a negatively curved universe without dark energy would expand forever. The universe would end in a heat death (known as Big Chill as well), or Big Rip. Basically a heat death is where entropy (or disorder) increases in an isolated system (system = universe).

WebAccording to current cosmological theories, the universe is open if it is insufficiently dense. Such a universe will never end, but will eventually become very cold and dark because stars gradually lose all of their energy. Compare closed universe. See Note at big bang.

The pattern of peaks and troughs persists in curved universes but is shifted to smaller scales for a open universes (Ω K > 0), while the opposite happens for closed universes (Ω K < 0).
WebThe closed universe can be finite in size, and can thus oscillate from one finite size to a larger finite size back to a smaller finite size. Black holes: When the universe gets sufficiently old and cold, eventually black holes become hotter than the background radiation. This is a really long time from now.
WebSep 23, 2016 · Even without understanding dark matter or discovering dark energy, scientists knew that the geometry of the universe was remarkably close to flat. A universe that supports life must be close to flat, but flat is unstable.
