Is time malleable?
It would be helpful to start with a definition of time: "the indefinite continued progress of existence and events in the past, present, and future regarded as a whole". With this as a foundation, we can analyze time “as a whole,” and isolate this variable. We can place it into its own container. I prefer using an entire dimension so as not to disturb anything else. Doing this eliminates any confounding variables.
Since time is an abstract idea, it lends itself well to copies. We can have “time” exist in all dimensions, simultaneously. Each copy is connected, yet distinct from the others. This one iota of overlap, we will call the tether. It cannot be physically occupied and merely serves as a breadcrumb trail, which will also serve as quantifiable signposts for mapping purposes.
A change in one copy affects all the others. To what degree, is unknown without a thorough inspection. In all my research, I have yet to find a change that could not be accounted for, confirmation that the whole is intact.
This is a seed, metaphorically speaking. If we plant it into the fertile ground as we did, water it, feed it with sunlight, and tend to its vital needs, it will sprout.
As you can see, “time” appears to be shapeable, trimmable, growable, neglectable, and therefore malleable. If this was too brief of an answer, you will have to excuse me. I am on a silent protest and quitting quietly. I still did my duty, though. I presented the data as simply as possible, but not simpler.
