The insulation would likely be some type of spray-on foam over aluminum tanks, so not a lot of weight penalty there. Cooling likely wouldn't be done, I assume any excess hydrogen boil-off that couldn't be burned immediately would

Only gaseous hydrogen is stored in heavy tanks under high pressure. As explained in the article, gaseous hydrogen has been deemed infeasible for aviation and the idea is to use liquid hydrogen. No high pressure involved.

Near instantaneous. In the paper it is described as "noise-cancelling".

I agree, but such observations weren't part of the linked study so it has no business making claims about it. They simply compared a few deterministic strategies with a random strategy.

This is difficult to interpret without the details of the original agreement, which are not mentioned in the post. If google was paying more than the ad revenue on the content, then not extending the agreement would be reasonable.

You can't "walk" in this 1.6G. You'd experience it while floating freely in space. And the stress on your body would be tension instead of compression. I guess it would feel like hanging upside down, except that your blo

"Small" Dyson sphere is relative. The tidal forces at 50km from an earth-mass black hole would still be pretty significant, so it probably couldn't be smaller than that. E.g. to pick something on the scale of a human, the dif

It's ironic that you're critiquing the algorithm for not making sense, while contradicting yourself in your first sentence. Did you lose interest "half way", or "after the second paragraph"? It can't be bo

If you fire people just for asking questions (possibly after misunderstanding the intent of the question like in this case), then it seems likely you'll end up with a team of sycophants that only tell you what you want to hear.

Wouldn't it be possible to see this experimentally? You'd find particles jumping out of a "potential energy well" which they shouldn't be able to escape via tunneling.

If the wavefunction is assumed to only encode epistemic uncertainty of the observer, then how are phenomena like tunneling explained?

I didn't really mean it as a "rebuttal", as the paper is careful about not claiming any causal link. I meant it as a warning to the reader to be careful about drawing conclusions like that. To establish causation you'd n

Correlation is not causation. For example, having a healthy social life may promote both alcohol consumption and cognitive function.

Where is the research paper that found this "brain function short circuit"? The CBC article doesn't shed much light on the claim made in the title, and seems to link to a few different older papers.

Diesel exhaust soot density is in the 1 to 2 g/cm3 range. Flour is about 0.6 g/cm3. So the soot is indeed a bit heavier. But you can adjust the amount of flour you weigh out to visualize the volume, and it still seems like a lot.
