"I need your help."
"No, no, no. We won't help you. You're taking a serious risk."
"I have to get in."
"You could die."
Since Shaklyn 1 failed to upload a digital copy of themself Shaklyn 2 throws Shaklyn 1 in a black hole.
Space within a black hole is governed by the same set of rules as space outside a black hole. It means all the things they call real are just a projection of information stored in a distant 2D surface!
"You think that s/he is lost forever but the information of Shaklyn 1 is not lost; instead the information is stored in the 2D surface of the Event Horizon of the blackhole and you can use the information to reconstruct Shaklyn 1 outside the black hole."
"If you're thinking what I think you're thinking."
"What are you talking about?"
"Set the timer for 120 minutes."
"60 is safer. I'm setting it at 60."
1-2-0.
Back in the present they recreate Shaklyn 1.
Shaklyn 1 now wants to find all out.
