The Drake Equation

The Drake equation is:

N=R_{*}\cdot f_{\mathrm {p} }\cdot n_{\mathrm {e} }\cdot f_{\mathrm {l} }\cdot f_{\mathrm {i} }\cdot f_{\mathrm {c} }\cdot L

where:

N

= the number of civilizations in our galaxy with which communication might be possible (i.e. which are on our current past light cone);

and

R *

= the average rate of star formation in our galaxy

f p

= the fraction of those stars that have planets

n e

= the average number of planets that can potentially support life per star that has planets

f l

= the fraction of planets that could support life that actually develop life at some point

f i

= the fraction of planets with life that actually go on to develop intelligent life (civilizations)

f c

= the fraction of civilizations that develop a technology that releases detectable signs of their existence into space

L

= the length of time for which such civilizations release detectable signals into space

The orbs, traveling along the twisting double helix DNA strand, are covered with silver metal leafing and represent carbon molecules.

Carbon is a primary component of all known life on Earth.

How common is DNA?

I do believe we are not the only intelligent life in our galaxy.

I also believe we are not the only life in our solar system.
