Yet US2 is still under development, and they're trying to make the program hyper realistic, so therefore, if Hawking Radiation were simulated, then it would be doom for all computers, it would take more than all the memory, CPU and RAM to emit even the tiniest bit of Hawking Radiation from a decaying Black Hole, and as the decaying goes on, then it could take up to 10-7 gigabytes of memory, and we don't have that much on even NASA's supercomputers, and the explosion of the black hole wouldn't even be witnessed because the computer would burst long before that even happened.
Plus, we don't know if Hawking Radiation exists, it's only a theory, we don't know anything about it.
