„Es wird einen Punkt in der Zukunft geben, an dem eine Zivilisation aufblicken und feststellen wird, dass sich alles wegbewegt. Und wenn sie über die Technologie dafür verfügen, werden sie versuchen, alles zu erbeuten, was sie können, bevor es verschwindet“, sagt der Astrophysiker Dan Hooper in seinem Aufsatz „Life Versus Dark Energy“.

This assumes a K3+ civilization that is so advanced that it expects to still be around in the same form qaudrillions of years later and is worried about energy needs in the year 10^100.
There is plenty enough in the milky way I’ll tell you what. More than you can shake a stick at.
Interesting article. A well presented short read with links to papers if you want to fall down the rabbit hole. Essentially, light has a maximum distance travelled of 63 billion light years if it was emitted at the Big Bang, 15 billion light years now. In 100-150 billion years, our local galaxies will have merged and all other galaxies will be beyond the horizon, where not even light can ever reach them. This will be the ‘fortress galaxy’ that life will have to hold together to continue existence.
I don’t think any civilization would exist for the length of time needed to worry about fundamental changes to the universe.
Plus, a civilization existing 150 billion years from now will likely be fine-tuned to the environment of a 150 billion+ (163.7 Billion) year old universe and maybe not need to do anything to change it.
