Scientific notation is a way to express numbers that are either very small or very large. In traditional notation the first kind would have a lot of 0s between the decimal point and the first significant figure whereas the second kind would have a large number of trailing 0s. The need for scientific notation arose from advances in various branches of science: atomic particles in physics or chemistry, astronomical or cosmological distances, size of single cell animals. Nowadays, even non-scientific values such as population, national debts (of some countries) could usefully utilize scientific notation.

Scientific notation is a way of representing numbers in the form

a*10b where 1 ≤|a| < 10 is a decimal number and b is an integer (negative or positive).

a is called the mantissa and b is called the exponent.

The advantages of scientific notation are greater with very large and very small numbers, the notation can be used for any number.

If the scientific notation stops at centillion why don't the numbers stop too?

Scientific notation allows for representing extremely large or small numbers using a simpler format. The system itself does not set a limit on the numbers that can be written in scientific notation. However, beyond a certain point, numbers become so large that they are not practical or meaningful in most scientific or everyday contexts, which is why the representation is typically stopped at centillion.
