It’s been a long standing bone of contention with anyone seriously considering alien civillisations… Do we broadcast our presence in hopes of meeting someone, or do we stay quiet in case we contact someone we’d rather not? Alexander Zaitsev, of … Continue reading
Everyone knows the Deathstar. By now, it’s surely an iconic depiction of power and technological potential. As such, it’s a pretty good example of the bizarre field of astroengineering. In other words, designing and engineering objects on an astrophysical scale. … Continue reading
