tkulogo, you're imagining it like a cone. Understandable considering the typical deceptions of black holes but it's more like spacetime gets compressed so a ship and everything else will too, until it all gets crushed to a point and then is spewed out the other side and is uncompressed. This is where one major problem is...how do you keep it open, so that you aren't crushed to a point in which case you will be destroyed? The only way you can do this is with exotic matter, which we haven't discovered yet. If you want to imagine it like a cone then imagine the cube getting smaller as it goes into the cone.

All of this kind of thing would need to be programmed to happen if wormholes were added to US2, otherwise people will be complaining "Why don't wormholes work like they really do!?" similar to some threads I've seen here about the current implementation of black holes.

Welcome to the Damos system this system is very solar system like with many planets asteroids and dwarf planets in the system, I will also do listing different this time so here i go.

Moon amount around objects

Venistis: 0

Polom: 0

Calandis: 1

Hars: 0 (2 undiscovered meaning they're not in system yet)

Mitosim: 10 (90 other moons are not discovered)

Voton: 2 (80 other moons have not been found)

Normas: 5 (25 other moons were not found yet

Valastom: 3 (19 other moons were not discovered yet)

2055 LOM55: 1

2088 LOM88: 1

Plomo: 1

Sadom: 0

2080 LKM80: 2 (I will include this asteroid since it has 2 of them)

Torpas: 0 (3 asteroid like moons were not discovered yet)


Asteroids
The asteroids in this system have no true names in the system yet because the objects are too far from Damos.

Star and planet sizes
(note no asteroids and dwarf planets are appearing here)

Damos: 1.50 times the mass of sun and a radius of 904150 km.

Venistis: 20 times the mass of moon and a radius of 4248 km.

Polom: 2.31 times the mass of Earth and a radius of 7485 km.

Calandis: 2.84 times the mass of Earth and is the radius of 8713 km.

Hars: 25 times the mass of moon and a radius of 3908 km.

Mitosim: 3.20 times the mass of Jupiter and a radius of 150309 km.

Voton: 240 times the mass of earth and a radius of 52713 km.

Normas: 17.5 times the mass of earth and a radius of 25157 km.

Valastom: 24.2 times the mass of earth and a radius of 40703 km.

so i've been doing some lagbusting on blacraft

first i measured tps while loading various sets of chunks in blacraft, making 36 measurements, each covering a different subset of 28 predefined "subregions".



then the mspt (milliseconds per tick) is described by mspt = Ax + noise, and the cost is |mspt - Ax|
i used l1 norm (laplacian noise model) because the measurement error is probably pretty heavy tailed
A is the matrix of coefficients which contains information on which subregions were loaded for each measurement

there are some more details and details, such as the fact that mspt under 50 is not measurable, mspt is always positive, etc, which i took into account

after optimizing the cost, this is what i get

each row is a separate measurement
column 1: the cost associated with this measurement
column 2: the expected mspt for this measurement
column 3: the actual mspt for this measurement
column 4: the error in mspt
column 5/6: the expected and actual tps

anyway if you compare the predicted and actual results they're actually pretty close -- under 0.5 tps error in almost all cases, which i'm sure is less than my measurement error

 [  0.638  50.     50.251  -0.251  20.     19.9  ]]

this also gives the mspt cost of each subregion -- remember each measurement consists of a set of subregions, so this is a decomposition of where that cost comes from
Code: [Select]
[ 1.193  9.595 33.261  6.168  5.874  5.641  0.187 -0.     0.374  3.268
 13.511  0.61   0.007  0.012  0.634  4.804  4.96   1.652  2.778  0.001
 15.503  3.059  3.746  0.574  0.703  6.552 12.687  6.248]

the first 4 subregions are in order
1. 441 chunks in the end void
2. spawntown spawn chunks
3. 21x21 chunk region in spawntown minus spawn chunks (a donut shape)
4. 500ish chunks of random terrain

and the rest of the subregions are actually a grid pattern over konisshi, which was the main target of this exercise. each of the rest of the subregions are pretty much 5x5 chunks of konisshi.

you can see that all of konisshi adds up to almost 94 mspt, which is pretty hefty. spawntown by comparison is a lightweight 43 mspt (although i'm comparing 540 chunks of konisshi to 289 of spawntown here)

i've attached a plot of these subregions in the correct geographic orientation, and you can see most of the lag is concentrated in a few of these subregions (yellower is laggier)

also attached code, which contains the Greatest List Comphrenension of All Time

Code: [Select]
    measurement_regions = [
        [item for sublist in [subregion_map[x] for x in region] for item in sublist]
        for region in measurement_regions
    ]

Universe Sandbox | Discussion / Spaceship Physics?
« Last post by KimJammer on April 15, 2019, 08:28:44 PM »
In the latest Universe Sandbox newsletter, I noticed they were hiring for a position called the Spaceship Physics Developer. While I definitely know that this won't happen anytime soon or perhaps ever, it still makes me excited about where I think the developers are trying to take this game.

Also on the job description site, it said, "planned megastructures/tethers feature"?? Cool!

So, what would be possible if we had spaceships with thrust and modular parts? Let's imagine!
Would it allow for better historical craft simulations? Could it show launches of historical vehicles? Perhaps the stagings of launches too?

Here's where I got the info: https://giant-army.breezy.hr/p/b2383bc2b995-spaceship-physics-developer
(Guys, let's be nice to the developers and try not to put out way too outlandish suggestions. Remember, it was just a job opening.)
