We can demonstrate the likelihood of this mathematically, using something called the Drake equation.

Many equations, including the Drake equation use estimates as the basis for their calculations and predictions.

This section discusses and attempts to list the best current estimates for the parameters of the Drake equation.

The Drake equation estimated the number of radio-broadcasting civilizations in the galaxy.

As many skeptics have pointed out, the Drake equation can give a very wide range of values, depending on the assumptions.

The Drake equation has been used by both optimists and pessimists with wildly differing results.

Some computations of the Drake equation, given different assumptions:

His discussion is centered around the Drake Equation.

But in terms of the Drake Equation, the explanations can be divided into three classes:

The theories and principles in the Drake equation are closely related to the Fermi paradox.

They discussed the Drake equation, used to estimate the number of communicative extraterrestrial civilizations in our galaxy.

It has led to the Drake equation, which seeks to estimate the number of intelligent civilizations in the galaxy, and listening programs using radio telescopes.

It's called the Drake equation.

Speaking precisely, the Drake equation is literally meaningless...

You know the Drake equation?"

Drake equation may also refer to:

Criticism of the Drake equation follows mostly from the observation that the terms in the equation are entirely based on conjecture.

The Drake equation has proved controversial since several of its factors are currently unknown, and estimates of their values span a very wide range.

For assumption 2 we must consider the L term of the Drake equation, and the timescale over which intelligent biological life can form.

A deeper objection is that the very form of the Drake equation assumes that civilizations arise and then die out within their original star systems.

Each of these hypothesized explanations is essentially an argument for decreasing the value of one or more of the terms in the Drake equation.

Others note that the Drake equation ignores many factors that might be relevant to the odds of contacting other civilizations.

The Drake equation states that:

"Hell, if the Drake Equation is right, there are millions of Minshara-class planets you can colonize."

The Drake equation is an estimation of how many planets in the Milky Way are inhabited by intelligent life forms.
