Simulated reality
open-in-new
<p>A simulated reality is an approximation of <a href="/facts/Reality/oC1xokDB">reality</a> created in a <a href="/facts/Simulation/Q4QJV1oI">simulation</a>, usually in a set of circumstances in which something is engineered to appear real when it is not. </p><p>Most concepts invoking a simulated reality relate to some form of <a href="/facts/Computer_simulation/Re6o8vzN">computer simulation</a>, whether through the creation of a <a href="/facts/Virtual_reality/0psDGsxT">virtual reality</a> that creates appearance of being in a real world, or a theoretical process like <a href="/facts/Mind_uploading/Egs4sJpN">mind uploading</a>, in which a mind could be uploaded into a computer simulation. A <a href="/facts/Digital_twin/CIajYd9S">digital twin</a> is a simulation of a real thing, created for purposes such as testing engineering outcomes. </p>
