The best way to find out would be to try it.

| Quote Watsisname ( ) That's about 16 billion light years from the Earth to the nearest points on the edges, so the SE universe is pretty big, comparable in size to the real observable universe!
Actually no, the observable universe has 90 billion light years in diameter, because the space expands faster than light, so the universe can (and is) bigger in size than it's own age.

| That's because space-time itself can expand at speeds greater than c, even though matter within it can only travel at speeds slower than c, with respect to local space.

| brenotarga that's not even a factor of 3 difference, which I would call very comparable in an astronomical setting. It's not very fair to compare co-moving distance anyway since SE's universe is static.

| Does SE really have 10 trillion galaxies?I mean i cant even explore one in my lifetime!
Space Engine is a game of dreams!
Also,i have seen a lot of players scared of being near black holes.Im not scared of black holes,but of going into deep ocean...Im always so scared to go down there....Why?
When will our goverments forget about the borders,and start looking into the stars as a species?

Yes.

Probably it is that primal fear of what might be lurking nearby but just out of sight, which is very rational in the deep ocean because all sorts of creatures, many still unknown, thrive there. In a very real sense we understand more about black holes and their interiors than we do about what lives in the deep ocean. But in another sense they are also very similar. Both appear as dark abysses that swallow light, both are inhospitable to human life (black holes even more fundamentally so), and both will crush you if you are too close/deep and unprotected (again, black holes even more fundamentally so). Monstrous things live in the deep ocean, and a different but even more dangerous kind of monster lives deep inside a black hole.
For these reasons my rational mind makes me fear being too close to a black hole much more, but I still wouldn't want to go to the deep ocean. I'm very adverse to the thought of having hundreds of atmospheres of pressure over me.

| Cool,SE is really big!
Thanks for the explanation 
Also,its so bad that we are trying to discover life on other planets,but we never even discovered 100% of Earth life.In oceans,we only discovered 5% of life there,its scary to imagine what is hiding in those depths...
Also,Europa and Titan could be potential life carriers...Europa may be hiding an ocean beneath the crust,on Titan,it may be exotic life...Also Mars could still have underground oceans with life....
So interesting to think that way
When will our goverments forget about the borders,and start looking into the stars as a species?

| I just flew to the edge of the SE universe. It took me a few days as I can't go too fast in denser areas. My computer crashes with it trying to do the calculations too fast - but I find it realistic to have some limits. I visited a few galaxies along the way to keep the journey interesting, but mostly hit Shift H and kept the Milky Way centered and flew backward away from it.
I think it's cool that at the edge everything seems to be red shifted. That brought up the question, would we be visiting objects as they were 5 billion years ago, or as they would be today? It's a moot question I guess, as I think after a certain point the engine takes over from real objects anyway, and it was stated above this universe is static.
Nevertheless, this program is a great way to get an inkling of how small and insignificant we really are. It's only a fraction of the size of the real universe, yet you can feel completely lost and alone within it, the distances even within our own neighborhood are inconceivable to the human mind. This ought to be an educational tool in schools around the globe!

| The engine portrays all galaxies at the same (present) era in the universe's evolution, since galactic/cosmic evolution is not currently simulated. It does depict the effect of redshift though, as you noticed. But no light-travel delay, so aside from the color galaxies look the same no matter how far away you are from them.
In reality if you made the trip to a galaxy 5 billion light years away, then (assuming you're limited to the speed of light and not using a wormhole or other hypothetical construct) you'd arrive to find it at least 5 billion years in the future, even though only a very short time might pass for you by relativity. And there are galaxies so far away from us that even at the speed of light you can never reach them. The expansion "pulls" them away faster than you can cover the distance.

| Hi. I am new here. For whatever reason, I can't post a new thread. But, I have a question related to this thread. I am running version 0.9.7.3. I picked a direction and just headed that way as fast as I could. How big physically is the universe in this program? After a while the galaxies stopped appearing. But, I am over 650 Gly in one direction and I am still going! I just have all black on the screen. How far does it go? Thank you. Added (27.10.2015, 03:39)
---------------------------------------------
Okay, I have gone out to 1,500Gly and it's still going!

| ^ The game engine will stop generating galaxies, as you have noticed, but it will not prevent you from continuing to move indefinitely. However, you'll probably notice pretty soon that your position will start jittering and a variety of other bugs will start to occur, as is typical when traveling huge distances in a game.

| I went further than 1,500 Gly before I stopped. I didn't notice any jittery position values or other bugs.

It's not bugs it's the simulation of going beyond the universe where physics breaks down 
Living among the stars, I find my way. I grow in strength through knowledge of the space I occupy, until I become the ruler of my own interstellar empire of sorts. Though The world was made for the day, I was made for the night, and thus, the universe itself is within my destiny.
