Truer word's have never been spoken. Nothing can escape Time… not even a "plasmoid" (For brother Mordo of course kek)
I have a theory. I think electricity/light can indeed be faster than linear time. See the pic for reference. Linear time can only travel in angles. Electricity /light travels in spirals in 3d. The hounds represents the guardians of the edges of linear time in Astral travel and the Astral traveler travels through electricity currents which are spirals therefore travels faster than linear time. It also could mean you could travel past the edges of linear time therefore allowing you to see the future.
Astral time traveling.
