Help!

I want to figure out roughly how many steps it would take to walk to the end of the observable universe.

Observable Universe: roughly 93 billion light years. (93,000,000,000)

Light year: 6 trillion miles. (6,000,000,000,000)

Rough estimate of steps in a mile: 2000.

I need help figuring this out. But I'm trying to find the mathematical answer. (not some weird number like 3.987 x 10 to the seventeenth power) I need the full number with all the zeros and what not.
If you need the distance of anymore things to figure it out, I'll get them. Any help would be awesome! Thanks!

If you need all the 0's, here they are:

\(\displaystyle 1,116,000,000,000,000,000,000,000,000=1.116\times 10^{27}\)


That is 1 nonillion and 116 octillion steps.

All you have to do is count up all the zeros in your given numbers, then add a 93*6*2=1116 to the front of the zeros.

There are 12 zeros in the 6 trillion. 9 zeros in the 93 billion and 3 zeros in the 2000. For a total of 12+9+3=24 zeros.

This is why we use 'that weird number' called scientific notation,

Instead of writing out something enormous.

It's only powers of 10. To count powers of 10 just move the decimal point.

You can also write it as \(\displaystyle 1116\times 10^{24}\). The power changes as you move the decimal point.

I'd rather take one big step and float the rest of the way.
