Voyager 1 & 2 is one of my favourite human science achievements, not even so much from technology standpoint, as it's relatively simple compared to what we have now (although that's one of the charms), but just the fact that it's so far away, it still more or less works long after the scheduled mission end time, we can communicate with it and despite all the modern technology progress, it would take decades to catch…

A large amount of Voyager 1 & 2 's success isn't just technological it is the ability to take advantage of a specific planetary alignment for a gravity assist [1] that can only occur every 175 years [2] .

Fingers crossed, if we manage not to blow each other up until then, we have 126 years to go till we can try again.

They are dangerous and reckless. They were also done in the name of humanity, but without humanity’s consent. I despise the naive scientists who did them as much as those who brought the damocletian sword of nuclear weapons on us.

I assume you are against them due to the silent forest hypothesis? Better not announce ourselves, because anything out there might not be friendly to us?

The dark forest hypothesis assumes that it's easy to travel between stars, so interstellar conquests are possible. But it doesn't seem to be the case.

There are no material goods that can justify the material and energetic expense of any interstellar travel. You'd be far better off just using a particle accelerator to forge any chemical element and then assemble them into molecules using nano-replicators.

The best you can do is to send information, possibly with the help of gravitational lensing.

Sci-fi mode on: given that the potential galactic civilization is going to be information-based, who's to say the Earth is not already under attack? An interstellar fleet of large invasion ships with soldiers is not feasible, but a small drone with an AI that connects to terrestrial networks and steers the civilization towards collapse is possible. I'd start investigating if TikTok algorithm developers got some nudges from a weirdly knowledgeable source.

Would sending voyager have been a real definite deadline?

Absolutely. You could wait decades or centuries for a useful planetary alignment.

Not really. Jupiter alone is good enough. Its huge mass accounts for almost all of the gain you get from any such slingshot. Launch windows from Jupiter to anywhere occur every 12 years. Voyager's alignment was captivating, but realistically if it hadn't happened, we would have just done separate Jupiter-Uranus and Jupiter-Neptune missions instead.

Don't forget that the mission planners figured out the "Grand Tour", calculating orbits and trajectories to slingshot around the Solar System. All with 1960s technology.

Why do some uploaders make it unavailable in certain countries?

licensing probably

But for an advert?

You can rent videos from YouTube, wouldn't you just make the video available but charge for it?

There's almost certainly less than 69KB of useful human-readable information on any given page.

I was actually a bit curious how much HN uses, since it's probably the lightest site that I frequent. According to Brave's dev tools, looks like just shy of about 90kb on this comment page as of the time of this writing. Obviously some of that is going to be CSS rules, a small amount of JS (I think for the upvotes and the comment-collapse), but I don't think anyone here called HN "bloated". Even that one page wouldn'…

Elaborate please.

For some good portion of the earth's population, I dont think things would go worse than it is even if there were an alian invasion.
