Cyclic-date (similar to stardate) infinitely long ago, a highly intelligent alien race (the: Qwertys) travelled the universe, exploring and inhabiting numerous planets. Amongst other technological achievements, they’d developed the ability to reinforce and genetically advance their DNA, such that microscopic samples could withstand the vacuum of space for millions of years without degrading (tougher than tardigrades), having the potential for self-regeneration into living beings once exposed to a suitable environment.
Once in a while via conformal cyclic cosmology, 4D spacetime's totality of projections (massive stuff’s relative experience of events in space) effectively thins out, as all the remaining matter decays into massless particles of energy (e.g., photons), which eventually causes a critical build-up of energy in spacetime’s subspace (think: Star Trek) type-existence, causing any remaining relative spatial existences to effectively get redefined as part of the newly emerging universe.
The Qwertys had managed to adapt their DNA degradation technology to allow them to encode and store their entire accumulation of knowledge, to be reused by their descendants once suitable planets are formed within each cyclic iteration.
In the year 2020 of our current cyclic-count, the Qwertys noticed a strange entry in their history books – an emoji of a cheesy grin... from a guy going by the name “Cantor” – it turns out the Qwertys had written the wrong cyclic-date: “∞” on page: 1/0 of their history book – the cyclic-date should have in fact been: “1-0-0” of the cyclic-time continuum.
Phew – Paradox Avoided: The apparent break in the chain of “cyclic-counts” had been puzzling the Qwertys for quite some time, since they understood that it was impossible to count (up, down, or alternating) an infinite number of times – an infinite number of “cyclic-counts” would have meant it was impossible for them to have arrived at their present day.
