https://en.m.wikipedia.org/wiki/Skewes%27s_number https://en.m.wikipedia.org/wiki/Skewes%27s_number In number theory, Skewes's number is any of several large numbers used by the South African mathematician Stanley Skewes as upper bounds for the smallest natural number x for which the prime-counting function is greater than the logarithmic integral function. The current best estimate we have for when this happens is: 1.397162×10^316 To put that in context... it's such a big number it's hard to put in context - I've been trying to make a physical analogy, but I think its bigger than the number of Planck-length cubes that could fit in the visible universe.
