I was in a museum in Sardinia (was part of Carthage) sometime ago and saw some of the tophets mentioned in the article. The argument from the linked article was repeated on one of the info boards - that the Romans demonized their enemies and lots of our sources on alleged child sacrifice come from them. I am not sure about the Carthagenian sources on the matter, but they did not make it into the argument, so I assume the evidence was either slimmer or newer.
You can sleep safely. Waiting for 10^14 years will take a while - by that time, no new stars are born in Milkomeda, and the Sun's white dwarf remnant has cooled down to a point of no longer being visible by naked eye. (edit: of course, it's not reasonable to assume that the 500 impacts / year will be constant till the end of time)
Hitting a random human on Earth, though, is a munch higher likelihood - around 0.04% per year if I did my numbers right.
> It is worth speculating that a remarkable catastrophe, such as the destruction of Tall el-Hammam by a cosmic object, may have generated an oral tradition that, after being passed down through many generations, became the source of the written story of biblical Sodom in Genesis. The description in Genesis of the destruction of an urban center in the Dead Sea area is consistent with having been an eyewitness account of a cosmic airburst, e.g., (i) stones fell from the sky; (ii) fire came down from the sky; (iii) thick smoke rose from the fires; (iv) a major city was devastated; (v) city inhabitants were killed; and (vi) area crops were destroyed.
Fun fact: looks like we're both in MPE (although I left two years ago).
Women were better represented in USSR's STEM fields that in the US. For example, Between 1962 and 1964, women were awarded 40 percent of the chemistry PhD, while in the US that number was five percent [1].
I recently went to see my grandmother, and she showed me her Physics collage graduation pics - there was only one man in their class of ten students. And no, it was not due to WWII raising women/men ratio - born in the 30-ies her generation was too young to be drafted.

One of the reasons they've imaged M87* rather than a black hole in our own galaxy was to avoid dealing with ISM scattering - we don't have to look through our edge-on disk, so it's easier to image another galaxy's center somehow. But the Sgr A* image might be in the works already, it was mentioned in both the press-conference and one of the paper's future work section.
Unfortunately, you can only do interferometry with simultaneous measurements (we need information about the difference in the phase of light hitting the receiving antennas), so the motion of Earth around the Sun is largely irrelevant, unless you can park another antenna at a trailing orbit (see space VLBI for that).
What you're thinking of is probably parallax measurements of distance - that's how missions like Gaia can pinpoint distances to stars in Milky Way (and some in its satellites as well).
Furthermore, adding more telescopes will help better image the fainter features in the image (due to larger total collecting surface).
