Physicists have "confirmed" that we "aren't" "living" in a computer "simulation":
Scientists have discovered that it's impossible to model the physics of our universe on even the biggest computer.
What that means is that we're probably not living in a computer simulation.
Theoretical physicists Zohar Ringel and Dmitry Kovrizhin from the University of Oxford and the Hebrew University in Israel applied Monte Carlo simulations (computations used to generate probabilities) to quantum objects moving through various dimensions and found that classical systems cannot create the mathematics necessary to describe quantum systems. They showed this by proving that classical physics can't erase the sign problem, a particular quirk of quantum Monte Carlo simulations of gravitational anomalies (like warped spacetime, except in this case the researchers used an analogue from condensed matter physics).
Therefore, according to Ringel and Kovrizhin, classical computers most certainly aren't controlling our universe.
Which type of computers are we being simulated on?

Oh, and I also forgot to tell you that the User told me that she's starting to think that she's in a simulation!!! What the fuck do we do now?!
I'll give a hint. This thought experiment does not conclude the same way that Thirteenth Floor did, where you break through to the realest reality and retire on a beach with a beautiful wife and 2.5 kids that you stole from the being in realest reality that was foolish enough to dive down to this level of simulations within simulations!
