Chapter 68 The Age of Escape
"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."
Lu Chen continued, "However, humans at that time guessed it might take thirty to forty billion years before the collision would occur. Such a distant time did not concern people much, and I too had overlooked it momentarily. Now that I think about it, we’ve been traveling for quite a long time since leaving the Solar System, and considering the speed of the two giant nebulae’s movement surely increases over time, the collision will probably happen much sooner than predicted."
"That’s terrifying! The Milky Way nebula has a diameter of over a hundred thousand light-years, Andromeda Nebula has more than two hundred thousand light-years. Such a huge collision between two giants is unprecedented even in the universe, the result will definitely be both spectacular and catastrophic!" Wandering couldn’t help but feel alarmed.
At the same time, he was curious about what that moment would look like.
Lu Chen said, "Of course, the collision of such massive nebulae, the energy level released is unimaginable, even massive constant stars could be instantly obliterated, which is why I asked you to catch up quickly. Our primary task now is no longer to absorb interstellar material for growth, but to flee the Milky Way first; otherwise, once the two giant nebulae collide, given our position is on the edge of the Perseus arm of the Milky Way, we are sure to perish!"
