@Userisjamie @cammakingminds That doesn't matter much until you get further out towards the unstable regions. It does have an effect here, it's just tiny and easily corrected by the many planned trajectory correction burns.

If you are using the earth as a reference frame, the moon is actually doing a close flyby of Artemis II.

@cammakingminds is the loop around the moon triggered just by moon's gravity or it is supported by any engines?

@melosyna @TheAaronBowley @cammakingminds The existence of spacetime has never been proven, science isn't ontological. It's all models, same for magnetic fields, and... everything really. These are incredibly good models, we should use them, but don't confuse them as somehow describing reality, they don't.

I'm both these things but this movie isn't either. PHM was a fun movie about friendship in the most unusual of places, adventure, and optimism in the face of overwhelming odds. Trying to make those things left-wing or right-wing is dumb. I see both of sides doing this and it annoys me to no end.

Project Hail Mary is so good because it's an inherently right-wing and Christian movie, like all great science fiction.

@StayHmming @Barchart Maybe is not about who is having more . Maybe behind the scenes there are more creative and innovative ways to harness energy already like SBSP?

@rcbenker @martinmbauer Science has never been ontological. More intuitive doesn't mean more correct. The universe has no obligation to make sense to us.

If by you mean, add an additional patchwork to incomplete physics frameworks, yes. My mind is not ready for multiple explanations that don't resolve with out magic darkness being added in to make it eventually fail again. We have incredibly precise methods of measuring the "what" and pretend they are explaining the "how".

@MatthewRideout @lucid_bound @TylerGlaiel This only works because as you lean forward, you are doing so too slowly to overcome the friction with the ground. Then you suddenly lean back, overcoming friction. This doesn't work in a frictionless environment like space.

@catofoom @stupidtechtakes Individual change is not enough. We already know the solutions, we have know them and have them available already. But systemic change is required. Solar is one such solution.

@Kiryln1 @duncsquire We still need some incredible propulsion, radiation shielding (relativistic particle shower), and even then might still need an insane amount of fuel, to where the ship is overwhelmingly fuel tanks and needs to be assembled in orbit like the ISS was. But it would be amazing.

@RealLastApostle @MathisPNewton @lukOlejnik Making anti-matter is so hilariously inefficient. It's probably the worst choice for a bomb, lol. You'd be better off just carrying some normal explosives, or a nuke.

@MathisPNewton @lukOlejnik That is what they say yes. But with the amount of lies they try to feed us today, i would not be surprised if Germany is gone in a few days, when that truck hit the target location. It would be the "Next big thing" to focus attention on after the failure in Iran.

A truck carrying antiprotons will drive across Europe. A team at CERN just transported antimatter across the laboratory's campus in a truck. Literally. 92 antiprotons packed into a portable trap weighing one tonne. As everyone knows, antimatter annihilates on contact with ordinary matter - which is basically everything. The final destination is Germany: Heinrich Heine University in Düsseldorf. An extraordinary delivery in the history of road transport. home.cern/news/press-rel…

@Kronykal The energy released by you blinking is far more than what this anti-matter would release.

@TolaimShelEldad @Tygget @cmanahlmagic Only from an outside perspective. What matters is that the trip is a lot shorter for the occupants than they expected, they spent a lot less time burning than they thought they would. Because the entire universe length-contracted, the ship arrived in a way shorter trip.

@Tygget @cmanahlmagic yeah, but physically if you don't understand relativity, then you also don't know that your ship is more massive when it is fast, so if you do accelerate it to near light speed you'd be using that fuel

In the book Rocky has the extra fuel because his people don't understand relativity, but in the movie he's making his trip 6 years longer to save Grace. The former is better from a worldbuilding perspective, the latter is better from a story perspective. Both reasons are great.

@Shaun_Fosmark @Hassaan_PHY The problem is, new discoveries are nigh-untestable. We require increasingly more ridiculous machines, some are even predicted to require machines larger than the Earth. We really are reaching some incredible limits.

1. Everyone else doesn't agree that physicists have lost the plot. There is a significant number of people who think this (often lay audience led astray by people like yourself), but certainly not everyone. Whoever is under the impression that everyone thinks this way is stuck in an echo chamber. 2. If a large number of people believe something, that doesn't make it true. It is more about public perception, which is clearly not dictated by facts (especially today). Large numbers of people have had many other erroneous beliefs in the past (a long list can be provided here) 3. Theoretical Physics isn't as successful in the 21st century as it was, say, in the first quarter of the 20th century. However, the reasons for this fact don't include the talking points that you have helped spread, e.g., "Physicists are lying for grant money". #physics #scicomm
Sabine Hossenfelder@skdh

he's entirely right of course. even if you think he is wrong, at the very least physicists should think about why everyone else agrees they've lost the plot.

@cybergrunk @ChadNotChud It perpetuates the myth that lower complexity means faster. Only when you approach infinity... it's a somewhat harmful myth for performance.
