The groundbreaking simulation allowed scientists to better understand a phenomenon that could entirely change the structure of the universe – and about which little is still known
Given our assumed half-life of the proton, nucleons (protons and bound neutrons) will have undergone roughly 1,000 half-lives by the time the universe is 10 43 years old. This means that there will be roughly 0.5 1,000 (approximately 10 −301 ) as many nucleons; as there are an estimated 10 80 protons currently in the universe, [ 41 ] none ...
That might mean there are unknown forces at work in the universe, for instance, or that there is a gap in our understanding of the cosmos that could require new physics.
In this scenario, the universe spends the vast majority of eternity in a featureless state of heat death; however, over enough eons, eventually a very rare thermal fluctuation will occur where atoms bounce off each other in exactly such a way as to form a substructure equivalent to our entire observable universe. Boltzmann argues that, while ...

In physical cosmology, the Big Rip is a hypothetical cosmological model concerning the ultimate fate of the universe, in which the matter of the universe, from stars and galaxies to atoms and subatomic particles, and even spacetime itself, is progressively torn apart by the expansion of the universe at a certain time in the future, until distances between particles will infinitely increase.
In general, dark energy is a catch-all term for any hypothesized field with negative pressure, usually with a density that changes as the universe expands. Some cosmologists are studying whether dark energy which varies in time (due to a portion of it being caused by a scalar field in the early universe) can solve the crisis in cosmology. [7]
