from "Clean Tech" channel description with video:
"In this video, we look at an astonishing and unexpected cosmic event: Pluto has collided with Neptune, and the results are quite frightening. For decades, Pluto and Neptune have had a peculiar relationship in space, with their orbits avoiding direct collision despite crossing paths.
However, recent astronomical measurements suggest that this once-impossible scenario has now become a reality, and the findings are sending shockwaves across the scientific community.
How does this collision affect our solar system?
Could this occurrence have far-reaching consequences that we are only beginning to understand?
We'll go over how this unexpected meeting between Pluto and Neptune occurred, what scientists have discovered, and the unexplained aftereffects that are currently unfolding in the far reaches of our cosmic neighbourhood.
Join us as we explore this unusual planetary occurrence and uncover the secrets of what is going on beyond Earth's borders.
Prepare for jaw-dropping findings as we unearth the hidden forces at work and investigate what happens next following this catastrophic cosmic collision."
