Miner's "OH NO" number

Miner's "OH NO" Number is so big, that it is $\frac{1}{\Re}$ of the size of the omniverse. (If number is in litt milleniums).

Formula:

$MO_1$ = 1 followed by 1 zero

$MO_2$ = $MO_1$ followed by $MO_1$ zeros

$MO_{3}$ = $MO_2$ followed by $MO_2$ zeros

...

$MO_{118}$ = $MO_{117}$ followed by $MO_{117}$ zeros

$MO_{119}$ = $MO_{118}$ followed by $MO_{117}$ zeros

$MO_{120}$ = $MO_{119}$ followed by $MO_{119}$ zeros

Then

${MO_{120}}^{MO_{120}} \uparrow \uparrow \uparrow 333$

Conclusion: Miner's OH NO number = ${MO_{120}}^{MO_{120}} \uparrow \uparrow \uparrow 333$).
