It would take that long on the computers we use. Big calculations and being they are physicist You should be able to think of some. like how would you change something that has already happened, maybe, How would you can it? can it be done? can you bring power items from, another dimension oh, yes that would be one.

Now, have you seen the one where they are looking at a monitor and healing a scientist over there with their hands over her abdomen? Healed in less than either 3 hours or less it was fast but I forget how fast, it could have been 3 minute, but 3 hours seems better. She had a tumor in her abdomen, now it is gone.

Yes things are going on, and it is in the bible about healing and raising the dead but not in his name so, who know what they are doing.
