"So could my daughter still be alive on the other timeline? If so, how do I jump? "

The problem is that at any given time the number of alternative outcomes in the next moment are enormous. I hesitate to say infinite, but the number would be equally unimaginable.

For instance - keeping an example simple - your next action has two choices therefore two alternative future realities, then your next action combine with mine - 4 alternatives - so just taking the world population x 2 alternatives - 2 to the power of more than 6 billion.

On a much smaller level, but still limiting to human action - 2 to the power of 6 billion to the power of the number of simultaneous synaptic jumps.

That is just at one 'moment'. Then raise that to the power of number of moments per second x 60 x 60 x 24. That is the total number of possible future realities based on human action in one day.

So it not just about making the jump, but knowing where to jump to.
