I know it's not really a sphere and the image suggests an open structure.  But most people agree -- the image (as below) is going to be a hubworld (similar to the Citadel, and Omega).  I believe it will be our ARK that will also function as our main hub (aside from our ship).

 

 

 

 

Tying this into the Dyson Sphere (If you are familiar with Star Trek, then you know you what the Dyson Sphere is) if not, please click here.  

 

Do you think something like this could be possible? Even though it is based on science fiction?

The original idea of a Dyson sphere isn´t a massive sphere built around a sun but something that collects all energy emitted by the sun. The geth used a lot of ultra light satellites equipped with solar sails for example.  The fullmetal dyson sphere is rather ehm impractical and fulfills no purpose besides being a deathtrap.

It actually more closely resembles a variation of a Bernal Sphere, not a Dyson Sphere. Could you be mixing those two up, maybe? I made a long post in the wormhole thread about why it resembles a particular type of Bernal Sphere (such as that incorporated into the hypothetical designs of relativistic starships), and posted two pieces of art from NASA's space habitat designs back in the 70's from a Bernal Sphere which are very similar to that concept art. Also, two other things are worth noting - the artists of Mass Effect took direct inspiration from these very same, real life designs for a number of things - but most notably the Stanford Torus of the Presidium - and so it is their M.O. for sure. Secondly, the concept art picture is definitely not a Stanford Torus like the Presidium, as the ground is not perpendicular to the assumed axis of rotation.

Thanks, I did mix the two up/

Sorry for the double post. Here is the art that I posted in the other thread for comparison (apparently I can't embed pictures from my phone here, so you'll just have to click on the link).

You can see the similarity. Bernal Spheres are useful as space stations as well; however, if you are building a relativistic starship and want to create an artificial gravity of 1g but your method of acceleration is less than that, then you have to spin the ship and use a modified Bernal Sphere design.

The main difference between a Bernal Sphere used as a space station and one used as a starship, for those that are interested, is that for a space station the 1g region is exactly at the spheres equator and therefore conceptually similar to a Stanford torus at that region. But for a starship with constant acceleration, it is not at the equator - but 30,40, etc degrees depending on the linear degree of acceleration.

The greater the acceleration, the "flatter" the ground appears relative to the axis of rotation. With a constant acceleration of 1g, the habitat does not have to spin and in fact doesn't need to be a sphere at all, but rather a flat surface - thus a much more "normal" starship design except the floors would be perpendicular to the direction of acceleration.

Side note**: For those that have seen the movie Interstellar, the starship at the end appears to be a modified O'Neil Cylinder with characteristics of a Bernal Sphere as well.
