Googol means that 1 is followed by 100 zeros, which is the power of 100. Gugor Plex is still smaller than some specially defined giants, such as those represented by Gartner Arrow symbol or steinhaus symbol.

The order of quantity units from small to large: from small to large, it is, 10, 100, 1000, 1 100 million, trillion, Beijing, Yi, Yi, Gou, Jian, Zheng, Zai.

Decimal system is below 10,000, and decimal system is after 10,000, that is, 10 million is 100 million, trillion is 1 trillion, and 10,000 Beijing is a shame. Numbers with large numbers are generally expressed by scientific notation, such as 90500000000000; We can use 9.05× 10 12, which means that the decimal point after 9 in the number 9.05 is shifted to the right 12.

The size of Gugor

It is said that there are no particles in the whole Hubble volume. Ordinary matter in the universe is made up of atoms, and atoms are made up of protons, neutrons and electrons. Protons and neutrons have more basic structures, consisting of three quarks respectively.

According to a large number of observation data, scientists know the density and radius of matter in Hubble volume and the proportion of ordinary matter in the total matter in the universe. After calculation, scientists estimate that the total number of elementary particles in the universe is about 3.28× 10 80, which is no more than one Gugor. It should be noted that this result does not take into account photons with zero rest mass and neutrinos with extremely small mass (neutrinos are one million times smaller than electrons).
