The star Gliese 710 will pass as close as 0.0676 parsecs—0.221 light-years (14,000 astronomical units) [45] to the Sun before moving away. This will gravitationally perturb members of the Oort cloud, a halo of icy bodies orbiting at the edge of the Solar System, thereafter raising the likelihood of a cometary impact in the inner Solar System. [46] There is a roughly 1% chance that Jupiter's gravity may make Mercury's orbit so eccentric as to cross Venus's orbit by this time, sending the inner Solar System into chaos. Other possible scenarios include Mercury colliding with the Sun, being ejected from the Solar System, or colliding with Venus or Earth. [101] [102] Collisions between brown dwarfs will create new red dwarfs on a marginal level: on average, about 100 stars will be shining in what was once the Milky Way. Collisions between stellar remnants will create occasional supernovae. [9] Carroll SB. Evo–devo and an expanding evolutionary synthesis: a genetic theory of morphological evolution.

Mars reaches the same solar flux the Earth did when it first formed, 4.5 billion years ago from today. [90]The small red dwarf Ross 248 will pass within 3.024 light-years of Earth, becoming the closest star to the Sun. [28] It will recede after about 8,000 years, making first Alpha Centauri (again) and then Gliese 445 the nearest stars [28] ( see timeline).

High estimate until all plant life dies out, assuming some form of photosynthesis is possible despite extremely low carbon dioxide levels. If this is possible, rising temperatures will make any animal life unsustainable from this point on. [86] [87] [88] Meteor Crater, a large impact crater in Arizona considered the "freshest" of its kind, will have worn away. [43] The Moon may collide with the Earth or be torn apart to form an orbital ring due to the decay of its orbit, assuming the Earth and Moon are not engulfed by the red giant Sun.

The estimated time for a Boltzmann brain to appear in the vacuum via a spontaneous entropy decrease.

[52] When I started reading stuff about spec. evo., I learned that there are three great types of genera: future evolution, alternative evolution, and xenobiology. However, Serina did exist and I couldn't find what type suited Serina, but, here (on Reddit) I noticed people using the word "seeded world" in reference to Serina. Biémont C.

Around this timescale most stellar remnants and other objects are ejected from the remains of their galactic cluster. [141]

The past decade has seen the addition of modifiers to evo–devo to reflect its embracing of other fields. Thus: The estimated time by which the expansion of the universe isolates all gravitationally bound structures within their own cosmological horizon. At this point, the universe has expanded by a factor of more than 100 million from today, and even individual exiled stars are isolated. [129]
