1'000'000'000'000'000'000'000'000 m (10 to the 24 m)

In a cube of 100'000'000 light years across and contains about 1'000 galaxies, each with 100'000'000'000 stars. This means that in this, compared with the entire universe very small dice, there are 100'000'000'000'000 stars. This number as 1'000 notes would fill again traveled many euro pallets!

1'000'000'000'000'000'000'000'000 Bq (10 to the 24 Bq)

So many Bequerel we will see artificial form on Earth in operation in all reactors and reprocessing plants. It was probably built not even full, so we have to count any portion of the radioactive core of the earth.

Now comes the hammer . We are now at 10 to 24, a huge number. 60% of them respectively 6.02E+23 H2O molecules are in exactly 18 g of water. Do you have any further questions?

10'000'000'000'000'000'000'000'000 m (10 to the 25 m)

In a cube of 1'000'000'000 light years across contains about 1'000'000 galaxies, each with 100'000'000'000 stars. This means that there are in this cube a total of about 10 to 17 stars.

10'000'000'000'000'000'000'000'000 Bq (10 to the 25 Bq)

So many Bequerel natural activity contains the earth's crust under the assumption that the crust is on average 50 km on average a strong and specific activity of 500 Bq/kg, is. The exact value is as high as about 3.2E +25 Bq. The radionuclides are present K-40 with about 500 Bq/kg, Ra-226 with about 340 Bq/kg and Th-232 with about 40 Bq/kg. The volume of the Earth's crust is 2.5E +22 liters and the mass at a density of 2.5 kg/l approx 6.4E +22 kg.

100'000'000'000'000'000'000'000'000 m (10 to the 26 m)

In a cube of 10'000'000'000 light years across contains about 1'000'000'000 galaxies, each with 100'000'000'000 stars. This means that in the observable universe contains at least 10 to 20 stars. We are now in the distance range of the known expansion of the universe.

100'000'000'000'000'000'000'000'000 Bq (10 to the 26 Bq)

So many Bequerel of natural activity of the isotopes K-40, Ra-226, U 235, U 238, Th-232 are in the earth's crust and the rest of the earth's interior. The basis for this calculation is the estimated heat capacity of 1.6E +13 W generated by the nuclear decay of naturally occurring radionuclides in the soil, is released continuously. This heat output is about the electrical output of 10'000 large nuclear power plants, each with 1'600 MW. The earth's interior has been kept warm for this reason, during the long lifetime of already 4.5 billion years ago. Accordingly, even geothermal power plants benefit from nuclear energy.
