↑ There is a roughly 1 in 100,000 chance that the Earth might be ejected into interstellar space by a stellar encounter before this point, and a 1 in 3 million chance that it will then be captured by another star. Were this to happen, life, assuming it survived the interstellar journey, could potentially continue for far longer.
↑ Based upon the weighted least-squares best fit on p. 16 of Kalirai et al. with the initial mass equal to a solar mass.
1 2 Around 264 half-lives. Tyson et al. employ the computation with a different value for half-life.
↑ 10 10 26 {\displaystyle 10^{10^{26}}} is 1 followed by 1026 (100 septillion) zeroes.
↑ Although listed in years for convenience, the numbers beyond this point are so vast that their digits would remain unchanged regardless of which conventional units they were listed in, be they nanoseconds or star lifespans.
