Quote from: Baruch on July 17, 2019, 04:24:41 PMDowntown Denver 109 years ago, due to coal burning, was a lot dirtier than today. But now Denver covers a much larger area. The initial objection to coal burning (which came about because of a shortage of wood to burn) was all the soot it produced.

Quote from: Sal1981 on July 16, 2019, 07:45:53 PMThe variables in the Drake equation isn't based on anything tangible, as we have no data points to any of them other than just our own.
Quote from: Blackleaf on July 18, 2019, 09:36:12 PMI don't care if there is intelligent life out there. ANY life whatsoever would be super interesting to find. Back before the game Spore died, I used to make and collect animals for an alien zoo.
Quote from: trdsf on July 19, 2019, 04:57:09 AMThe only real use in the Drake Equation is for helping frame one's thoughts about the prevalence of intelligent life in the galaxy, and in the universe. Drake himself proposed it in that way, not as a solid mathematical theory of extraterrestrial intelligence. Until we have a galaxy-wide survey of life, intelligence, and the circumstances under which civilizations live and die, that's all it can be.
QuoteWhat is Fermi's Paradox?Do aliens exist?Can it be solved. Dr. Duncan Forgan explores that in his new book "Solving Fermi's Paradox", asking if aliens and alien civilizations exist. Where are they? Why aren't they here yet? And what factors can keep a civilization from advancing. What if they are long since dead, how do we look for ancient alien civilizations. John Michael Godier also spoke to Dr. Forgan on Event Horizon about the protocols for what we should do if we find intelligent life. Especially life that is far more advanced, what do we do if we see a Dyson sphere? How will the world react, and how should that information be shared.
