Radhaan's lips parted, but he said nothing, trying his hardest to school his twitching facial muscles.
Time was something that moved in a straight arrow over space, and mass, stopping it was physically impossible without tearing down all space, causing timequakes— a single part of the universe being sent back a million years in the past, and the other forward, in simple words destroying the entire world.
As far as Radhaan's knowledge went for physics, Mass, space, and time were all interconnected, "mass" being living creatures, planets, galaxies, etc, existing, so they could age, cause let's say if there's nothing in this world to age to its eventual doom, there's no time.
Same with space, that's where everything is happening, if there's no space, there's nothing to hold it all.
