Centauri Dreams welcomes Ravi Kopparapu, a research associate in the Department of Geosciences at Pennsylvania State University. He obtained his Ph.D in Physics from Louisiana State University, working with the LIGO (Laser Interferometer Gravitational-wave Observatory) collaboration. After a brief stint as a LIGO postdoc at Penn State, Ravi switched to the exoplanet field and started working with Prof. James Kasting. His current research work includes estimating habitable zones around different kinds of stars, calculating the occurrence of exoplanets using the data from NASA’s Kepler space telescope, and understanding the bio-signatures that can potentially be detected by future space telescope missions.

    As I said on Viv’s post, it occurs to me that before we actually visit these other habitable worlds, (and I have no doubt we will someday) we first need to get it deeply engrained into our psyches that they are not there for us to ‘own’ or exploit for our own benefit.
    Also equally important, these planets may have life forms of their own, who, depending on whether or not they are more or less or differently advanced compared to us, have the right to say “No” to us and we then back off and leave them in peace.
    Not every neighbour wants to be ‘friends’ 😀
