Hydrogen is a great propellant if you are optimising for ISP. With a combustion chamber at a given temperature the average kinetic energy of the molecules is equal irrespective of the type of gas. If the gas is made up of lighter molecules those molecules will be moving faster. Faster molecules leads to faster exhaust velocity. Faster exhaust velocity leads to higher ISP. Higher ISP leads to hate. Hate leads to suffering. Matthew Oelkers
Name That Logical Fallacy
Hi, SGU! I came across the following fallacy used by Douglas Murray and Mosab Yousef in debates against critics of the IDF: ‘Unless you’ve been there, you cannot express an opinion on the issue, and since I’ve been there, I have more credibility than you.’ Someone made fun of that argument by saying: ‘Katy Perry therefore knows more about space than Stephen Hawking, because she’s been there and he hasn’t.’ I can’t quite pinpoint if this just an argument from authority, or if there’s something else to it.

A recent study finds that, despite advances, people are still able to distinguish in many cases between AI generated voices and human voices. https://www.eurekalert.org/news-releases/1099494
Skeptical Quote of the Week.
‘Inductive reasoning is, of course, good guessing, not sound reasoning, but the finest results in science have been obtained in this way. Calling the guess a “working hypothesis,” its consequences are tested by experiment in every conceivable way.’ — Joseph William Mellor
