Itīs easy to understand how the Garden time travels.
The gauge seems to be made of a special material,crystal-like.It looks like a piece of the crystal pillar.It probably distorts gravity.
Garden does not time travel. If you wish to say it does, back it up. Similarly with your claim that the 'gauge' is a piece of the pillar or that it distorts gravity.
When it rotates,itīs field rotates also.According to Lucca,a rotation field enables time travel.
So, when I spin a magnet, I enable time travel? Not all field rotation involves time travel,FE.
