I believe this is the estimated surface temperature on the sunlit side of the comet's nucleus. Just like the surface of the Moon and Mercury have a temperature of 390K and 670K despite not having a significant atmosphere.

One atmosphere isn't very hard to contain and if it fails it would just pop, not explode.

Almost anything you use now started out as a toy for the wealthy.

I wouldn't use the Titanic as example but the Costa Concordia...

Open voting on public elections is a very bad idea and directly undermines democracy. It leads directly to intimidation and bribery. Ever heard of employers forcing employees to vote on 'the right party' or find themselves without a job? That's why secret ballots are considered essential to democracy. Open voting by representatives on the other hand ensures voters can verify their chosen representative at least represents them and can adjust their voting in the next election (whether they actually do that is of course another matter).

I find attoparsecs more convenient in everyday use. But my daily commute is about a picoparsec.

Aerospace consultant? Did the shipbuilders also get to name the discoveries of explorers? But I highly doubt he was even involved in building the HARPS instrument or the ESO 3.6m Telescope. So it would be like some random ship builder in England naming Hispaniola "Some bloke's passed away granddad's place" after doing a contest about it and expect it to be accepted. What these Uwingu guys are doing is disrespectful for the discoverers, the IAU and the granddad. I wouldn't like it if people attached my name to a celestial body illegitimately.

After surfing around for 15 years I can say: Anyone claiming the porn got there by accident is lying. Certainly if it's 15yo kids.

They were sued into oblivion in 2039 after blue flashes of death on their time machine left users, well, a bit stretched out, from the Big Bang to their "starting point".

There are only 2 types of Earth crossing asteroids: Apollos with a semi major axis larger than 1AU and perihelion smaller than Earth's aphelion and Atens with a semi major axis smaller than 1AU and aphelion larger than Earth's perihelion. There are 4803 known Apollo asteroids (I don't know where the 5200 number in the summary comes from but IAU's Minor Planet Center knows of only 4803) and 747 known Atens, so there was a very good chance that the meteorite was an Apollo...

You need Tau Ceti's ecliptic coordinates to know it position relative to the orbit of Earth around the Sun. Those are -24.8159 degrees latitude and 17.8186 degrees longtiude. So Tau Ceti is almost 25 degrees below the ecliptic, not 15 above.

It certainly can be done and in fact has been done. Ulysses has a highly inclinded orbit around the sun with an inclination of 80.2 degrees. They did use Jupiter though.

You mean religions are better? You think crusades, genocides, jihads, dead sentences, stoning, human sacrifices etc., suppression of entire classes/genders..., you know, the stuff religions tend to do is better? Or worse? They might not be violent yet, but the hate they preach makes them fit in the religious nut job box quite well.

You intend to fight zombies with passports? To give them papercuts? Bundle them together and make a brick out of it?

During a gold rush many people became rich, but most of them were those selling supplies or services to the poor sods trying to find gold.
