Oh, and before I forget, in a future update, will the volume of the universe in Space Engine be increased from it's current size of about 1000 cubic Gpc to something even greater, perhaps nearing infinity? Of course, only if that is feasible. Thanks!
There was a thread where this topic kind of came up, and SE had a nice post about it...
Quote (SpaceEngineer) In SpaceEngine, as long as we have a hyperdrive, the entire Universe should be represented. Infinite space is impossible to represent on a PC, but some closed curved space is possible. 4D hypersphere may be made similiar to a planetary surface, which is 6 squares, curved and connected to each other. In the universe's case we should use 8 curved cubes, connected with each other by their faces. It is impossible to imagine, but can be described by formulas or implemented in code. A more easier way is to use topology of a hypertorus - just connect the left side of a cube to the right side, top side to the bottom and front to the back. When the camera crosses the left side it will get teleported to the right side, this gives an impression of a seamless closed space with no boundaries. Another approach is to make a so-called domain structure - giant volumes filled with regular galaxies, 100-200 billion light-years across, separated with 100-1000 trillion light-years of empty "false" vacuum (according to the expanded universe model). The Engine can handle trillions of such domains, like it handle stars in the galaxies now. But the easiest way is just to limit the maximum velocity of movement and make the universe really big, so going to the "edge" will take years in real-time. |

There's no "same way", galaxies and planets are generated in very different ways.

I don't know. I prefer to finish all features on which I am working now as soon as possible and start a beta test to be able to release new version before New Year.

| Okay, you know how when you are approaching an irregular galaxy it says loading stars and yet you don't see them? I'm just wondering what exactly is it loading because I tried to find one of those objects (by taking a screenshot), but the number came up as invalid.
It's not annoying me or anything, it just keeps making me wonder just what it is loading when I can't see the stars. My guess is that it might be loading the octrees or something.

| smjjames, why not have posted in this thread? No need to create a new thread for question about galaxies.

*facepalm* Sorry.  I just wasn't paying attention I guess. Thanks for the move though.

| I did try a search though, but I searched for irregular instead of galaxies since I was looking about a specific type.

| I am well aware that galaxies and planets are generated in completely different ways, SpaceEngineer . What I meant by saying "in the same way that planets do" is that procedurally generated satellite galaxies should be found around cataloged galaxies much like how procedurally generated planets can be found around cataloged stars. I was talking from a conceptual standpoint, not a technical standpoint when I said that they should generate in the same way that planets do. I do not know whether that makes any sense or not, but I do hope that satellite galaxies will be implemented into the game for the added atmosphere and exploration potential.
Thank you werdnaforever, I am apparently very bad at using the search function. I am having a hard time comprehending that last model that SpaceEngineer suggested, though. Would patches of galaxies hundreds of billions of years across be found randomly throughout a much larger area filled with empty vacuum space, with trillions of light years separating them? I'm probably missing something obvious here, but wouldn't that just defeat the purpose of everything? It would take a great deal of time to travel between these (What I'm assuming to be cubic) patches of galaxies due to the trillions of light years separating them, and it wouldn't look very realistic. Again, I could just be missing something here.

| Space Engineer, I'm just wondering where you get the data for the size of the catalog galaxies? I know you mentioned elsewhere that you use Hipparcos for the star catalog, but maybe you get the galaxy data from another source.

Source information is at the beginning of the galaxy catalog. Anyway determining galaxy size is simple. Just take the galaxy's distance and its angular size and do some trigonometry.

| Oh, okay.
Also, I don't know trigonometry, but I'm sure I can find some sort of calculator (or maybe that wulfram alpha math thing) to help me there.

Didn't you take it in high school? Sine, cosine, tangent, all that stuff? In any case it's all very simple.

| I'm just wondering how large SE actually is. It's interesting to explore such an enormous universe, but had to imagine how much it generates. It says "millions" and "trillions" on the homepage, but I have a gut feeling that there's more galaxies/stars/planets than that!

| Should be safe just to stick with what the homepage says. No real specific down to the last planet number exists,

| Jboy2468, I've moved your question here, we try to avoid similar thread. Thanks to use the search fonction of the site before creating a new thread.
Look at the OP, you'll have answers
(DoctorOfSpace) You are welcome to start counting though
