10 to the ...

In order to present large numbers easier, the exponent notation is used. By definition, 10^0 = 1, 10^1 = 10, 10^2 = 100, etc. Often you can see for the presentation of the Decades also the following notation: 1E+03 = 1'000, 1E+04 = 10'000 etc.

In this analysis, we compare systems with the unit meter [m], financials with the unit swiss francs [CHF], radioactivity with the unit becquerel [Bq] and the time with the unit second [s]. We move for each step at a » factor 10 higher.

Can we imagine large numbers?

Our sun is a relatively small star. But it has 100 times the diameter of the earth. On foot it would have at an average speed of 5 km/h approx 8000 hours - a whole year - for a walk around the Earth. The illustrated Andromeda galaxy contains 100'000'000'000 stars. Meanwhile, astronomers tools are available, which could theoretically 50 billion galaxies are identified. This means, therefore, be assumed that the universe 500'000'000'000'000'000'000 stars. Each of these stars has the 1'000'000 times the mass of Earth. The Earth has a mass of 5'900'000'000'000'000'000 tons - as 9.5 trillion tons. A average tall homo sapiens weights just 80 kg.

Unimaginably large stellar bodies

Unimaginably small molecules

Now comes the hammer. In 18 g of water - this is a small glass full of snap - write and say are 602'000'000'000'000'000'000'000 water molecules. In the oceans are about 1'000'000'000 cubic kilometers of water. One cubic kilometers, a volume of cubic meters or 1'000'000'000 1'000'000'000'000 liter. Imagine now how many water molecules are located in the oceans. There are 3E+46 (!) thereof.
