Conservation of Energy and Time

I'm in digital contact with the man who invented time travel, HK. From some knowledge he shared from different worldlines, certain facts are coming to light. Some of you may find this interesting, and if nothing else this can serve as a record in case I failed.
Two major facts stand out.

There is only one world
I have spoken of worldlines often, but they are not parallel worlds. They are alternative, possible states of affairs, with similar ones grouped together in an 'attractor field'. Think of it like a rope; it looks like one thing, but it's made of multiple strands, and multiple threads.
What matters is, none of these alternatives are real. There may be a multiverse (it seems likely) but that is independent of the worldline model.
Think of every entity in our world as a list: every property, and every event that happens to them is on that list. Altering the worldline is scratching out a term on that list, and writing another. This is important: it's not replacing a term, it's merely writing over it.
There are accounts of people recalling events from other worldlines. HK is one of them, and in a previous issue with time travel, he found many other situations. This would only be possible if the same people existed over multiple worldlines, rather than being multiple, different people who happen to share a history. We are the same people, no matter the worldline we are on.
The science isn't fully understood. It may be possible for non-conscious items to do something similar, but their physical properties would not change; this is conservation of energy, in a way. Their traits couldn't alter if it would change mass for just that object.
Memories however, as non-physical, massless objects are exempt. It is possible to reclaim memories from past worldlines. I am not certain of the mechanism: some people may have a natural inclination. It may be somehow contagious: the only situations I know of came from contact with someone who naturally possessed the ability (after a childhood illness: though that may just have been their first experience). If an illness causes it though, it may be triggered by some alteration to the physical brain.
From this, it follows:

It is impossible to never be born
Time may change, but as it is only the properties of memory, location etc that alter, at not the fundamental of the universe, energy must remain conserved.
The only seeming exception to this rule would be a time traveller, who travels from the future, and changes it. Would this make them never be born?
However, if they were never born, the mass and energy that makes that traveller up would not exist. Extra mass would have come, uncaused, into the universe.
In theory, this means that if a time traveller dies in the past, they would fail to change the future: the attractor field, without intervention, would draw the worldline back to one where they go to the past: so that they would be born, and travel back in time, so that their mass comes from somewhere. A mission could only suceed is they travel back to their time, in which case they would presumably be lost in the transition.
And then, later, when the time traveller is born, they would represent the mass that had existed in the past. Conservation of energy is not necessarily continuous, but everything must exist. Even if, in this new worldline, time travel is never invented, the energy remains conserved.

I hope this aids in understanding time travel, for any readers or other travellers.

Time travel could be a biological event.
Imagine a universe where no life ever came into being.
Mind Experiment:-
Imagine a planet similar to earth, but with no life. Everything on that planet would totally obey the laws of physics. Every rain drop would fall exactly where it should and every grain of sand would be in its exact correct position. Now put a mouse on a beach on that planet the mouse would move and disturb the grains of sand and raindrops would fall on the back of the mouse and not fall where they originally would have. It is almost as if life interferes with the natural order of the universe.
Would different timelines or multiverses etc. still occur in a dead universe with no life of any kind.

The interference there comes from the addition of a mouse which should not be there.
There is a tendency to think of life as somehow above the natural order. This is not true: life is the product of nature, and just as much part of it as any rain or grain of sand. The fact we are harder to predict doesn't make that false.

Multiple worldlines would exist no matter what: they are simple possibilities. The question would be whether they could be accessed: whether the worldline could be changed without an agent to do it.
And that is an interetsing question. The one I know who can recall other worldlines automatically can, as a result, sense when the worldline changes. This mainly occurred when he sent a 'D-mail,' an email via a primitive time machine that was received before it was sent. If this changed the past, then his sense would activate, and the worldline would change. However, surely the fact he was going to send the message would be sufficient for him to sense the change?
It gets further complicated when, on one occasion, the worldline shifted after a linear event: deleting a record from CERN's database of the existence of D-mail.

The implication seems to be that subjective experience is required for the worldline to shift: which is to be expected, as the shift of a worldline means the writing-over of memories and properties. Performing an action that would change the default future (with time travel, the outlier, remaining in the exact state it would in the advancement of that worldline) must be done and, at that moment, the worldline would change. While events occurring linearly, with no time machine, can change worldlines, this can only happen if it results from a change that has already been made in time.

So, what really matters, is whether natural time travel exists: whether there could be a natural, if unlikely, way for the worldline to change. I have heard no reports from HK on unexplained incidents, so it would seem unlikely, but this would not mean impossible.
In a universe with a different design, or different laws, however, even if life did not exist, this wouldn't prevent the shifting of worldlines. Life is nothing special. certainly, our consciousness makes regaining the written-over properties somewhat easier, but theoretically all matter can do that, even if we can't notice it doing so.

Life only interferes with the natural order, if you define the natural order to be 'that without life'. However, that seems an odd thing to do, as life results from nature: life would by definition be part of the natural order.

Therefore human consciousness is not different to or separated from nature but part of it. Makes sense! But this discussion is probably heading towards philosophy and free will etc. Wether human consciousness and actions can create or bring into existence new timelines or worldlines and if these are "natural" events?

We certainly can bring into existence new wordlines, it's happened many times. Well, we don't create 'new' worldlines, but we do switch the one we are on, to another. All this needs, though, is to alter the past.
As for whether it's natural, I can't say. That would require 'natural' to be defined. As far as 'progressing from nature' goes, yes, it is.

As an interesting note, to make major shifts in worldline, as in enough to change attractor fields, you need to access a hot spot. Theoretically though, these is one crucial way to end up in a worldline between attractor fields, not bound to events in one or the other. This would be to create a consistent history, even if you change the past. The only attempt to access the 'Gate' worldline, as we call it, involved a murder. A man found a woman, dead, in a pool of her own blood: and resulting from that was the first recorded 'D-mail'. Eventually, when that was over (a very long story), a version of me from another worldline gave him a chance to change the past, and also remove from existence the time travel thesis she worked for, which had ruined the future (this was the past Titor, I believe). To do so, he forced her attacker away, and knocked her unconscious into a pool of his own blood. When his past self saw the scene, he reacted the exact same way: leading to the events which would change the worldline.
That kind of consistency is rare, complicated, but powerful.
