User blog comment:HarmonyBass/Destiny Ramblings: The Vex and why they haven't won yet. (WARNING! MIGHT GIVE YOU A HEADACHE!)/@comment-25932172-20170609014644/@comment-160529-20170610133249

except for the part where it is stated repeatedly that the Black Garden is their birthplace, and that it is on mars.

And just because they were released from an Extra Dimensional realm by the Hive does not mean that they are from that realm to begin with.

Also yes the black garden is in a pocket dimension... or rather it was, if you at any point in time looked up, you would see that it is underground.

And if you actually payed attention, you would realize that when you destroy the heart, you are "back on mars"

yet you dont actually go anywhere.

and that when you return to the black garden (strike) that the Black Garden has not yet been returned to extra dimensional space, and is still on mars according to the dialogue.

....

WAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAIT

Do you think that other dimensions are alternate realities?

That is some old school ass misunderstanding of physics dude.

All dimensions exist within the same space, extra dimensional just means that they are existing on a plane of our reality synchronized with the larger whole... not that they are in pocked universes or realities.

to put it in simpler terms we have four primary dimensions we exist in, up and down, left to right, forward and back, and forward in time.

vex exist in something like this, but descynchronized from the rest of it and disconnected...

not a parallel reality, that is like... like have you been paying attention at all.

For all intents andp urposes the vex are just living in time bubbles.
