Cosmology & Origins
What is the ultimate fate of the universe?
PLAUSIBLEimportance 72/100 · Plausible Hypothesis
Whether the universe ends in heat death, a big rip, a collapse, or something else.
Current explanations
Under a cosmological constant, accelerated expansion leads to an asymptotically cold, empty, high-entropy state ("heat death"). Alternatives depend on dark energy's true nature.
Research progress
The fate hinges on the equation of state of dark energy, which is measured only approximately.
