### Re: 121: "Frozen Rivers"

Would there really be flooding? I’d guess most riverbeds have capacity for twice the usual volume. Breaking dams wouldn’t be all that catastrophic either since the water behind the dam would be frozen, thus not causing a huge, sudden flood but only melting slowly. I don’t know about the icebergs pil...

### Re: 1456: "On the Moon"

Is it "real"? I don't know. Is years of training, a brief visit in a heavy space suit, eating paste, and soaking up cosmic rays "real"? Long term habitation will be in a cave under 20 meters of rock, otherwise the secondaries from cosmic rays will give you a hell of a dose over ...

Himself wrote:Yes. That misconception is a bit of a pet peeve. Kinda funny that, given how big the universe is, that people would actually overestimate the distance between things.

They just underestimate the speed of light. Everything in Space is huge, so a couple (hundred) lightyears doesn’t sound much.

### Re: What-If 0115: "Into the Sun"

While we are discussing about units: Could it be that Americans are afraid of SI-prefixes or exponents? Those „X is 10,000,000 Y“ are just cumbersome and won’t help a layman anymore than „X is 10⁷ Y“. ns, ps, fs etc. should be pretty clear too (and if you want to explain them write „femto is 10⁻¹⁵“)...

### Re: What-If 0113: "Visit Every State"

You should now IMMEDIATELY switch to 10 gee deceleration, or you will fire out of the hole into the atmosphere for a brief high gee deceleration, then a fast trip out of the solar system. The earth does that for you. You can’t „fall out“ of a tunnel through the earth, you’ll oscillate from one end ...

### Re: What-If 106: "Ink Molecules"

I don’t understand the final answer. What is „161 pixels“ supposed to mean?
