That's interesting about the "giant star" hypothesis. I never knew that, and it makes sense based on what Kepler knew at the time. Today, we know that the apparent size of stars is an illusion due to diffraction. In principle

"Democracy is broken" means that the will of the people is largely ignored, regardless of who they elect. This has been demonstrated to be the case in the US [1]. What's wrong with government "increasing" as society

Well, many people seem to excuse luminaries of the past for things like slavery saying things like "It was a different time. They should only be judged through the lens of their own culture." It might not be a respectable system o

This is something I struggle with and am profoundly bothered that, in my 30s, I can't answer simple questions about my own personality. Things like: am I a morning person or a night person? How close am I to burning out? Introvert or e

Deaths per joule doesn't account for the safety issues if nuclear power were more widespread. The deaths caused by weapon proliferation and the long-term ecological impact of more nuclear accidents doesn't scale linearly. We can h

Peak oil in the United States did happen in the 1970s. It might have already happened globally, but the market is distorted due to sanctions against one of the world's largest oil exporters.

> One of the biggest takeaways was that many fusion efforts are very far away (3 to 6+ orders of magnitude) on the most important metric, Q, which is energy_out / energy_in. Keep in mind tokamaks have reached Q=0.7.

I'd be curious to see what elements (not chemical elements conceptual building blocks) are required for natural selection to take hold, irrespective of the physical form taken. Surely someone has looked at this on a more abstract level

"Recorded history" is too short for natural selection to occur. You don't get significant carbohydrates without agriculture, which is about as young. Besides, type 2 diabetes doesn't seem to have an impact on ability to

Right. But it is a possible mechanism that has nothing to do with the current thickness of the atmosphere or distance to the sun. Once upon a time, Venus wasn't so bad either. Is James Hanson not "serious"? I agree that the c

Water is one of the strongest greenhouse gases around, and there's plenty of it in the oceans that can evaporate in a runaway process. Once that happens, we're the next Venus. Reaching that tipping point is quite difficult though,

> I think we're safe. Well, it doesn't need to equal the irradiance of the sun to be a big effect. 1% of the sun is still a hell of a lot of extra warming. At an annual growth rate of 2%, that 12 TW becomes 1% of the sun in 250
