"Big brother, do you now understand what the giant nebula crisis is about?"
Wandering caught up with Lu Chen on the edge of the Three-leaf Nebula Core Region and asked curiously.
At this moment, the magnificent and dazzling Three-leaf Nebula was behind them, and what lay ahead was still wandering, endless wandering.
Lu Chen said, "I just learned while absorbing Cang Ming that the giant nebula refers to the Milky Way, and the giant nebula crisis refers to the century-scale collision between the Milky Way nebula and the Andromeda Nebula!"
"Isn't that just the prediction made by ancient human astronomers?" asked Wandering, puzzled.
Lu Chen explained, "Strictly speaking, it was not a prediction, but rather humans deduced it by observing the movement of the two giant nebulae; if the trajectories of their movement remain unchanged over the boundless span of time, then their collision is inevitable."
