I am sure there are lots of questions from Fermi, but I'll bet you mean the Fermi Paradox, which asks, "If there are ETs, where are they?" What he meant by this, is that the time to completely colonize the galaxy is very small compared to the age of the galaxy, so there should be ETs here if they exist at all!" So where are they--or alternatively what is wrong with this idea? For more on this please search "Fermi Paradox".
AnswerFermi questions, aka order of magnitude questions ask you to express something numerically that can only be vaguely guesstimated. An example would be how many golf balls does it take to fill the Atlantic Ocean? or how many quarters would it take to cover the surface of the Earth. Because the answers are simply a wild estimation, they are expressed by a power of ten. Say for example you calculated an answer to be 28374738, this would be the equivalent of 2.83 X 10^7, or in a Fermi question, expressed as an answer of 7. The easiest way to go about solving a Fermi question is by breaking it down to as many conversions that you are fairly certain of as possible.
1 Fermi is a quadrillionth of a metre ie 1 Fermi = 10-12 metre.

One fermi is one femtometer, which is equal to 10-15 meters, or 0.000,000,000,000,001 meters.

The spelling Fermi is an Italian surname, notably physicist Enrico Fermi (1901-1954).
Laura Fermi, an American author and wife of physicist Enrico Fermi, passed away on December 26, 1977.
EUR Fermi was created in 1955.
Laura Fermi was born in 1907.
Enrico Fermi had two siblings one sister and one brother: Maria and Giulio Fermi.
A fermi gas is a model from quantum mechanics first proposed by Fermi. A neutron star is said to be an example of a Fermi gas, and that would indeed be a dangerous place.
