This page lists times between 1018 seconds (an exasecond) and 1019 seconds (32 billion years and 320 billion years)
Beyond this point, only future events can be listed, as this span of time exceeds the scientifically determined age of the universe.
- 50 billion years: time until, assuming both survive the Sun's expansion, the Earth and the Moon become tidelocked, with each showing only one face to the other.
- 100 billion (1011) years: time until all galaxies recede from view, apart from those in the Local Group.
- By the end of this period, all the Solar System's actinide elements will have decayed to less than 1% their current value, leaving bismuth as the heaviest traceable element.
