Era

An Era is a very long period of time. Each Era is exponentially longer than the previous Era.

The Pencilcosmos' lifespan is considered to be exactly 16 Eras.

The start of an Era in LPT is calculated via this function, with n being the start of the nth Era: $$f(n) = 10^{log10(f(n-1) \times log10(f(n-2))}$$

The Pencilcosmos is currently in the 4th Era.

Here are the starts of all the Eras (except for the 1st Era):

The 2nd Era started in 0 LPT

The 3rd Era started in 10^9 LPT

The 4th Era started in 10^24 LPT

The 5th Era will start in the 10^216th LPT

The 6th Era will start in the 10^5184th LPT

The 7th Era will start in the 10^1119744th LPT

The 8th Era will start in the 10^5804752896th LPT

The 9th Era will start in the 10^6.499837e+15th LPT

The 10th Era will start in the 10^3.772995e+25th LPT

The 11th Era will start in the 10^2.452385e+41th LPT

The 12th Era will start in the 10^9.252836e+66th LPT

The 13th Era will start in the 10^2.269152e+108th LPT

The 14th Era will start in the 10^2.099609e+175th LPT

The 15th Era will start in the 10^4.764332e+283th LPT

The 16th Era will start in the 10^(1.000323434618800×10^459)th LPT

The 16th Era ends at the 10^(4.765872949904257×10^742)th LPT
