There are several ways that our species might try to send a message to another species separated from us by space and/or time.
A rationale for a museum of health
.Synthetic biology might be used to write an epitaph to our species, or simply “Kilroy was here”, in the genome of a bacterium via the patterns of either (1) the codons to exploit Life's non-equilibrium character or (2) the bases themselves to exploit Life's quasi-equilibrium character.We suggest here how DNA movies might be designed using such patterns.

.
We also suggest that a search for mechanisms to create and preserve such patterns might lead to a better understanding of modern cells.Finally, we argue that the cutting-edge microbiology and synthetic biology needed for the Kilroy project would put origin-of-life studies in the vanguard of research
