No, it’s going to work out great, the Dyson Sphere is going to be in the vacuum of space, and Dyson knows all about vacuums.
The first step of our project will be creating a massive vacuum designed to suck up the vacuum of space. If we remove enough space, the expansion of the universe should slow down and then reverse. With the galaxies and stars closer together, traveling to other solar systems will be much easier. And don’t worry about everything collapsing into a point of infinite densitiy. If stuff gets too close together, we can just let some of the vacuum back out of the bag.
We already have a small-scale prototype, pictured below:
This model can only handle single-planet atmospheres, but once we scale up to the final version, it is really going to suck.
