While some of this floating matter did not move from the area where they were suspended from, Azief is the one moving.
And as it took too much time for him to dodge each and every single thing in space, he just rammed his body to these matters.
The sound of explosion is muffled but the effect of the explosion was not spread out. He is still quite close to Earth.
He did not want the effect of him clashing with celestial objects to cause some changes on Earth
One must not underestimate the power of some celestial object veering off course. Earth now could probably survive large meteorites falling down from the sky
It is hard to believe, absurd even but as Azief had learn from his many journey in the Universe, when some mystical artifact is involved, absurdity is par for the course.
