Also here is a video of me flying through the milky way!

Also try to find out the distance to earth to see how fast a spaceship would need to fly to reach the place within a human lifespan.

If you go close enough to the speed of light, anything is reachable within a human lifespan...as far as the people onboard are concerned, anyway. If you want to reach anywhere within someone else's lifespan, forget about it. It won't happen unless it's real close.

Found absolutely awesome system:

What you are looking at is not 1 star system with weird one glowing planet but a 4 star system in which directly shows how according to science stars are formed.

AB and AA orbits each other. AB is brown dwarf super exceeding fusion mass needed to start fusion AA is your regular red dwarf. BUT there are also BB and BA which are larger than AB but have lower density and thus mass. They are still brown dwarves they are at limit in which they probably have some going on fusion internally but not enough mass to hold it for long.

Now most interesting object is that planet with ring around it. It is bigger than all of brown dwarves earlier but smaller than red sun BUT it has very very very small mass (about only 1/5 of BB). This is the best example i could find of how stars are formed and how much it needs to weight and how dense (how big it is) to form a star. All in one system.

If you go close enough to the speed of light, anything is reachable within a human lifespan...as far as the people onboard are concerned, anyway. If you want to reach anywhere within someone else's lifespan, forget about it. It won't happen unless it's real close.

correction. For light time doesn't exist (or should we say almost non existent). The moment light is emited is the same moment light falls upon. Only in our frame of reference we can streach out time nonexistence into something that we call time and we can perceive it.

Thus if you travel at speed of light you reach at end of universe same time you started your journey problem naturally is that rest of universe would probably cease to exist as there is no end so your would move into infinity unless you would hit something.

Another example. Light that is emited from sun actuall is milions years old because it bounces around in its core and then leaves sun hitting us. But from light perspective moment of emit is moment when light falls on earth.

let's welcome back webm format into thread.

If you want to post webm you need to use |webm| tag just with squares.

[MadMaxHellfire]

i set everything i could on max but my landscapes are not that detailed :/

 

[Perkel]

you are doing it wrong. First of don't set everything on max. In this game more =/= better.
For detailed surfaces you need to set LOD to 1 or 2.

Mind you that it requires lots of CPU and GPU power then

Thank you DraQ - that little trick did indeed work.

I found a black hole, and... nope. Never want to approach that terrifying thing again. D: Though - I wonder how the one in the middle of the milky way looks. Any idea how to navigate through that clusterfuck?

In middle of milky there is actually big black hole. Usually you don't see black holes lens effect until you are right next to it let alone from other planets in system. Milky way one is so big that you can see black hole lens distortion effect from light years away. Hell that black hole is orbited by like 15 or 20 stars.


How to find quickly black hole

center on galaxy and move into center just uding W or on galaxy map with scaler. When you reach middle of it it should usually be some globular and in that globular there will be supermassive black hole.

Unfortunetely black holes aren't really represented good in SE. One they don't have discs of hot gas nor jets. Secondly database from which data is gathered doesn't contain distance thus SE ommits most of black holes.

Biggest object in universe currently are black holes. Bigger than biggest starts:

Would love to see this with educational purposes. I know my love of space would've bloomed sooner if I had had access to such a beautiful program in high school.

It's ironic that Venus should have so bad complexion.

It's Venus, right? Looks like Venus.

Well the thing I think has vlue in these games/sims is learning the local stellr neighborhood. I mean, odds are our society will soon know the local stars like we know the large mountain ranges of Earth. Of course, the value of knowing these things is like knowing the dimensions of a carbon atom (340pm) but having the brains of a metal pot. Still, knowing that you know something which will probably be standard knowledge in the future is a way of connecting to the infinite.

Interesting, we're (logarithmically; relatively) closer to the size of the sun than to an atom. Anything larger than the sun is a more impresive jump up than it's the jump down to an atom. Interesting perspective on scale. Another thing I want to bring up is the distance between stars, that distance versus their size, and equivalence to galaxies. Curiously, it seems, it's more fantastic for stars than ti's galaxies. Translation: If you treat galaxies as single stars, the distances between them respective to their dsize is less than the distance between single stars. (Now, my thinking could be wrong, so I'd love to be correted).

Another thing which has always beeninteresting to me is the area our Earth encompasses versus the area the rays from the sun envelope. If the sun were a soccer ball, it'd be ~60 feet from the Earth which is about the size of a period in this sentence. When I first imagined this, I was captured by the grandiose field of light emanating from the Sun whereupon only a small pinpoint of it reaches Earth and fuels its proceses and keeps its life humming for billions of years. Most of the energy we now use comes from Coal and much of that derives from the solar energy having reached and fueld Earth for many millions of years.

And one more thing. I'm told the Earth has X amount of grains of sand on beaches on Earth. As I recall, there're as many stars in the observable universe as there're grains of sand on beaches on over 26,000 Earths. I'm also led to believe there're X numbers of human cells on Earth today 2015. It's a large count, as there must be trillions per human. There're also an approximate equal number of cells belonging to ants on Earth. One should think with all of the ants on Earth (Quadrillions?) surely their cell count would dwarf humanity, but as it turns out, ther're fewer cells per ant, so their total is reduced to accompany our own.

In regards life elsewhere, one only has to find life on a moon or comet or dwarf planet to greatly expand the likliehood of there being some form of life out there. Ther're some 160 moons in our solar system, a few dwarft planets inside and probably dozens outside. If life can prove worthy enough to grow on them then awindow isopen to a staggering number of potential sites in the cosmos. It's impressive enough of course if only only considers planets or rogue planets(even), as there must be billions of rocky Earth-similar planets in the Milky Way. What of life in the atmopshere of gas giants? And those rogue planets are a mystery. There could be billions, trillions or more of them roaming around here in our galactic neighborhood. Cool and far outside a stellar furnance, it's not imposible they might bubble up some heat frm below to keep warm a few humble and unordinary microorganisms.

EDIT: I strikethrough the grians of sand on Earth's beaches comment because I think ti' errored.

I'm pretty sure we are using different definitions of "interesting".

Regardles in whiehver which way it comes across, peace my friend, or friends. I like this stuff.

EDIT: Please ignore the grains of sand estimate. I researched tha a while ago and I pulled a bad number somewher. I just googled now and the number of grains per Earth if very much higher. So 26,000 Earth's is a hugely inflated number. Apparently, the number is closer to 50 of them. So if you added up all the grains of sand on beaches on Earth for 50 Earths it'd be equivalent to all the stars in our observable universe. This is based on the stimate here're about 5 sextillion grains of sand per Earth and ~250 sextillion stars in the observable universe.

Here's a link about the star estimate (which wrongl states 'universe'... we don't know how many stars in outside the observable... some say it's maybe infinite):

Pipemen. Your pics aren't working. Use imgur.

A picture of individual stars we know about. Globulars and open clusters(there are a lot of them) arent shown.

Another angle with Andromeda glaring in our direction, upper right.

An odd sight of 12 galaxies aligned and relatively close to each other. The camera is looking back at the colossal aggregate in the next picture.

Every galaxy we have given a name is shown here. Milky way is right in the middle, its disk aligned perpendicularly. Whole thing has an odd hourglass shape simply because we can't see through all that gas and dust along the galactic plane in our galaxy.

new version out http://en.spaceengine.org/load/core/spaceengine0973patch/2-1-0-31

 

[Perkel]

Looks like it improves performance a lot from what people are saying.

 

[Perkel]

 

[Perkel]

looks like he also improved a lot clouds math:

new feature: Layers

 

[hiver]

I cant figure out how to move in it.

Is there any help that is actually understandable about it in the program itself?

 

[Perkel]

wasd you move like in FPS shooter
zc you rotate camera
mouse wheel scroll you increase decrease acceleration from few meters per seconds to mln of light years per second.

There are also 3 types of camera. Standard is what is above, ship mode is where camera doesn't stop (x to stop camera)

Good way to find quickly planets:

Click with mouse on some star then or left panel choose solar system with planets (second one) and you will get whole system with miniatures of planets.

click on planet and then on lower left panel choose "move to planet" it will almost instantly take you to that planet. Same with landing.
