Wandering Meteor

The backflow wave from the halt of the expansion of the universe (expansion backflow) is like a giant wave in the sea chasing after billions of boats on the surface.

These "boats", whether large or small, vary in size, but without exception, are all desperately avoiding the deadly assault of the expansion backflow.

However, the expansion backflow differs from ordinary waves; waves have a limit in size and can be dodged by moving to the sides or diving into the sea. In contrast, where the expansion backflow passes, nothing can survive; there is simply no space to hide. The so-called evasion is just a race against time with the expansion backflow. Those who outrun it live; those who don’t, vanish from the universe!

Regarding the aforementioned sizes of the boats, besides describing the size of the planets that biological civilizations rely on for survival, it also serves to gauge the strength of a civilization’s power. The larger are naturally civilizations with stronger technological capabilities, and the smaller are civilizations with lesser technological productivity and lower energy utilization. Regardless of their strength, in order to avoid the threat of the expansion backflow, all civilizations are flying forward at full speed. Over time, small numbers accumulate, surpassing the number of civilizations that fled during the massive collision of the Galaxy Nebula and Xianhe Nebula. From a cosmic perspective, those faint light points spanning endless light-years resemble billions upon trillions of fireflies: tranquil, beautiful, and spectacular!

Of course, this tranquility is only on the vast cosmic scale. In reality, at the macroscopic level, this urgent moment of escape is far from peaceful.

After all, even humans have experienced numerous stampede incidents while fleeing.

However, things are different for civilizations escaping in the universe.

The main difference lies in the scale of available space. Human activity space is actually quite limited, especially in crowded situations where there’s almost no room to move;

Yet civilizations in the universe have an exceedingly vast space. Even if billions of civilizations gather together, they only occupy a very small fraction of the universe’s volume. The distances between them generally prevent close encounters due to both the vastness of the universe itself and each civilization’s cautious control of their planets’ flight paths, avoiding the Roche limit and planning their routes.

This foundation ensures that civilizations do not get too close to one another.
