riddle - I am in the beginning of time and space - What am I?

I am in the beginning of time and space. I stand for nothing, but I mean a lot. I cannot be divided into parts. What am I?

Answer

I'd guess you are:

0 - zero

I am in the beginning of time and space.

Depending on your date/time format, you might have leading zeros on hours, minutes, and seconds. Some spacial coordinates and many distance counters use leading zeros. A simple example is the mileage counter on a vehicle. Geo-spacial coordinates for latitude and longitude on Earth often, but not always, include leading zeros.

I stand for nothing, but I mean a lot.

A zero literally means a lack of everything, but if you string zeros behind another number, it can mean quite a lot. Example: 0 and 100000000. Also, zero is essentially what all other numbers are compared against, so that gives it significant meaning.

I cannot be divided into parts.

Zero can't be divided, since nothing can't be subdivided into smaller parts of nothing.
