Yeah, gravity assists are a cheat code here, but the delta-V is still being changed—just by stealing velocity from elsewhere.

Yeah, orbital mechanics gets a little bit mind-bendy sometimes. If you’re in a stable circular orbit, accelerating in the direction you’re traveling will actually result in you traveling more slowly because you have moved to a higher orbit, and firing engines to slow down will actually speed you up because you move in closer to the host body and take up a faster orbit.
This is actually a problem spacecraft deal with regularly. If a Dragon capsule is behind the ISS and wants to dock, using its thrusters to accelerate toward the ISS will actually result in it falling further behind. Decelerating will get it closer, though it will then be in a lower orbit. Orbital rendezvous is tough.
Ah, the ol’ Reddit switch-a-roo. Hold my relevant topic, I’m going in!
And my axe!!
I used to play the Beatles’ “Here Comes the S[o]n” on the speakers downstairs when I brought our first child downstairs after naps. My wife thought it was funny the first time, but after that it was all like “please don’t stop my playlist for your pun” and I’m like “it’s a literal dad joke!”
Now that son is old enough to start his own music and I totally get it. “Hey, I was listening to that!”
I don’t doubt that someone might be thinking that, but I do doubt that any lawyer thinks it’s necessary. As far as I know nobody has ever brought suit against a TV show for a suicide case.
But I’m not an attorney.
If you’re willing to settle for that kind of timeline, you could “launch someone into the sun” by just…leaving them on Earth for five billion years. At that point, the sun will become a red giant and probably expand to engulf the Earth.
Good question, but if you cancel out only a little bit of orbital velocity, you just orbit in a little bit closer. Without any appreciable drag acting on you, there’s nothing that will keep your orbit decaying. You’ll just be in a smaller, perhaps slightly more eccentric orbit.
It’s obviously a head shot of a person holding their hands in the air like they just don’t care.
Because the Earth is really cookin’, and anything anyone you hurl toward the sun will inherit that orbital velocity as well, meaning that they’ll actually end up going around the sun, instead of into it. And due to the speed it would pick up on its way in, it would basically take up a highly-eccentric yet stable elliptical orbit.
“Well, what if we throw them in the other direction, to make up for it?” That’s called retrograde, and that’s basically exactly what you’d have to do: cancel out the Earth’s entire orbital velocity. Which would take a lot of energy, plus a couple of really exacting gravity assists from planets on the way in.
(Edit to add: I may have explained this poorly. Basically, if you don’t change your orbital speed at all, any movement you make toward or away from the host body means you just end up in an orbit of the same average distance, but in a more eccentric [elliptical] shape.)
By contrast, even though the escape velocity from the solar system is no slouch (42 km/s), you get to start with the Earth’s orbital velocity (30 km/s)–meaning you’re already a little under 3/4 of the way there. Plus, if you can make it to Jupiter and Saturn, you can get a significant gravity assist, and they’re much bigger targets for such a maneuver than Mercury or Venus are.
So, yeah, bottom line: you only need a delta-V of about 12 km/s to get out of the solar system, but a delta-V of 30 km/s to get to the sun without going into orbit.
And the biggest clue to the truth of this is that the ACA is basically just RomneyCare with a few more individual protections bolted on. It was literally Mitt Romney’s plan to fix health care, and the Obama team used it because they knew that it could get support in the GOP.
Same. The other skins appear to work, but I’ve never really vibed with them.
I’ll have to check my math again. But are people uploading more than that? On my friend server, with 50 people, we’ve had about a dozen uploads all year, and they’re all pretty small PDFs and images. Everything else is rich links.
“Storage management is expensive”
It’s really not, though. Discord has 200,000,000 MAU. If every single one of them uploaded a file every month (of pretty much any size) and Discord tossed it into an AWS S3 IA bucket, it would cost them $500 to store that data. Their total S3 bill for storage would be five hundred US dollars. Storage is dirt cheap. AWS doesn’t even charge per gigabyte on that storage type, it’s so cheap; they charge for downloads.
So, ok. Let’s talk downloads. If each of those files were 25GB and downloaded twice (probably an underestimate, but not everyone is uploading files, so I’m going to make the completely unfounded assumption that it’ll all shake out), it would cost them a couple hundred thousand dollars. Which, ok, that’s much more significant than $500. But Discord made $575 million last year—so the S3 download costs would be 0.03% of their total revenue. They probably spend 2-3 times more on coffee.
Storage management is emphatically not expensive.
My guess? They just saw that the higher upload limit was eating into their Nitro subscriptions.
I’m not saying that would be a better experience for players, just that if they wanted it to succeed they should probably have done more marketing.
I’m not entirely oblivious to gaming news, but the literal first I had ever heard of this game was when they announced that it was being shut down. Methinks after eight years of development it could’ve had a few more dollars tossed into the marketing budget.
Every single one of them look like their eyes are about to roll right out of their heads.

So this is true (and increasingly so recently), but a lot of that overhead is technically unnecessary for the message to be sent and received; a lot of it is information about transmission and DKIM validation, spam protection, sender verification, etc; and then a TON of it is HTML for display. For a known receiver to send a message to a known recipient, I believe that a text-only email that’s cryptographically signed for identity validation could potentially be a tiny fraction of the size of a big huge HTML email.
There’s a guy on the internet who does videos comparing Vancouver real estate with literal European castles of a similar price. “Not livable” money in Vancouver can get you “has gardens and outbuildings with servant’s quarters” in some parts of Europe.
