Searching for advanced civilizations in other galaxies: 50 possible candidates found?

At first, this article seems like a bit of a downer: Search for advanced civilizations beyond Earth finds nothing obvious in 100,000 galaxies -- ScienceDaily. After searching 100,000 galaxies for signs of highly advanced life, a team of scientists has found no evidence of advanced civilizations there.

Dark energy may be less energetic than previously thought

This is interesting.  Astronomers discovered dark energy, the energy causing the rate of expansion rate of the universe to speed up, by looking at large numbers of Type 1a supernovae. Type 1a supernovae are white dwarfs (collapsed stars after their fusion has gone out) that explode.  What causes a previously stable white dwarf to explode? … Continue reading Dark energy may be less energetic than previously thought

Greg Egan’s Amalgam is close to the most likely interstellar civilization

The other day, I did a post engaging in speculation on, assuming we don't discover a completely new physics, what I thought an interstellar civilization might look like.  In summary: Given special relativity, travel faster than the speed of light is impossible.  This has been verified by innumerable experiments, and nothing in nature has been observed to … Continue reading Greg Egan’s Amalgam is close to the most likely interstellar civilization

One of the questions Stephen asks Massimo is what he thinks Hume's … Continue reading Stephen West and Massimo Pigliucci discuss David Hume

Why the Exodus, as commonly understood, probably never happened

At the urging of one of my relatives, I watched Ridley Scott's 'Exodus: Gods and Kings'.  This relative, knowing my skeptical nature, thought I might enjoy Scott's naturalistic (mostly) take on the events in the story.  I'm sorry to say that I didn't really enjoy the movie, which is unusual for me because I usually do enjoy … Continue reading Why the Exodus, as commonly understood, probably never happened

Interstellar: more accurate than the typical sci-fi movie, but still had issues

This week, I watched the movie Interstellar, the Christopher Nolan film about travel to another galaxy, a black hole, a wormhole, and other exotic environments.  I enjoyed it immensely, although I also had some issues with it. In the film, at some point in the future, the Earth is dying due to a global crop blight. … Continue reading Interstellar: more accurate than the typical sci-fi movie, but still had issues
