Nope. It's basically forgotten. At least, I haven't heard anyone talking about it, either in my circles or in the media.

Thanks for the explanation, it was very clear. Especially the bit about never being able to see your own private key. Ok I get it, it's to prevent malware from doing the same, but it still vaguely distasteful.

In my limited understanding, they are similar to SSH public/private key pairs. But the details continue to elude me, no matter how much I read about them. Won't try them out until I get how they work.

It's quite difficult with current rocket technology: you have to counteract most of the Earth-given 30km/s speed around the Sun in order to get close (it's smaller than Mercury's orbit), and then brake again to circularize the orbit once you are there. I am not sure that it can be done with what we have now. That said, it's not that far off either.

7.2 grams a day is still a lot. Low-sodium diets aim for less than 3 grams a day, and it is not that difficult to go even lower. Whether a near-zero sodium intake is good or not, it's another can of worms, but a study looking at a huge-salt diet vs. a high-salt diet does not look very useful.

Well, at least they don't sell seed oil :)

The ring is not a product of the supernova. It's pre-existing material, that is being energized by impact of the supernova ejecta (it took a few months for it to start brightening).

There are actually three rings, a smaller one around the previous star's equator, and two larger ones above and below. The hourglass-like figure is actually quite common, produced by the star rotaton.

It's a limitation of the Falcon Heavy, the launcher used this time. A future, more powerful one could do it while being reusable.

It goes on until an Earth's day is as long as a month. Both will face each other in a fixed way. But it takes many billions of years and the Sun will burn both to a cinder much before that.

It's not so uncommon in science to come to a strange conclusion by excluding all "reasonable" alternatives. For example, black holes have a similar status: no one has conclusively seen one, but we know of no mechanism for matter to support itself beyond a certain density, so black hole it is.

The day your wish is fullfilled is the day I stop working with Python. I can't stand all those useless braces everywhere, why are they there at all since good practice mandates proper indentation anyway?

I am at the point where I prefer single quotes for strings, instead of double quotes, just because they feel cleaner. And unfortunately pep8 sometimes mandates double quotes for reasons unknown.

Look for the Global Gender Gap Report of the World Economic Forum, it uses exactly that metric.
