G-HAT (Glimpsing Heat from Alien Technologies)

For those interested in the post about finding advanced civilizations in other galaxies by their heat emissions, Paul Gilster at Centauri Dreams has a write up about the study, including links to additional material as well as the actual paper. I found that this part clarified the seeming contradiction in the Science Daily article. The currently reported work … Continue reading G-HAT (Glimpsing Heat from Alien Technologies) →

Einstein, Schrodinger, and the reluctance to give up hard determinism

Ethan Siegel on his Starts With a Bang blog has an interesting review of Paul Halpern's new book on Einstein and Schrodinger, and their refusal to allow the implications of quantum physics to dissuade them from idea that the universe is strictly deterministic.  It's an interesting post and one that I recommend reading in full. … Continue reading Einstein, Schrodinger, and the reluctance to give up hard determinism →

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. The idea behind the research is that, if … Continue reading Searching for advanced civilizations in other galaxies: 50 possible candidates found? →

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 →

Should we fear AI? Neil deGrasse Tyson’s answer is the right one.

HuffPost has an article up with quotes from various people on the dangers, or non-dangers of artificial intelligence.  They include the usual suspects: Elon Musk, Stephen Hawking, Bill Gates, etc.  Most of them express concern about the dangers.  But I think Neil deGrasse Tyson's is the only answer from this group worth listening to. There are … Continue reading Should we fear AI? Neil deGrasse Tyson’s answer is the right one. →
