If anyone eventually gets what im going on about they might realise that through triatemption issues like time travel and earth parralisation might be a possiblity.
The answer is yes but because of the devergent nature of triatemption it's a connectivly hard to traverse problem.
You might if your clever then notice that trough quarticle progression we could reach a state of time travel ability and high efinity dynamic parallisation which might make you wonder how long this reality has been evolving for as to wondering your chances of going back in time to tell your grandad you love him.
Although this is a possiblity I can tell you both through deduction regarding the higher life collectivly grace and life experience your chances are not that good or ever going to be exacting if you try but that your dad is with you all the time and given the relationship with unity I havent got a clue what happened in different moments after he seemed to die and that even such and approach is to narrow and limited to be relavent as you change your self from moment to moment. However it's entirley likly the essence of his life is in positule memory all around you and probably to some degree in the positule memory of the high relative to this dimensional level of space so its entirely possible from essence he could be bought back.
As to everates parrallel worlds problem the tarmakwa is such that everates maths is to perfect.
As for light freezing well thats again is a matter of perspective an with deeper anaysis I think you'll find an issue regarding dimension traversal momentum and the counter entropic issue thus inccured.
