ต้องบอกก่อนว่าเป็นทฤษฎีหลุดโลกและไม่ใช่ mainstream physics แต่ลองวิเคราะห์กันดูครับว่า เป็นไปได้ไหมที่ความจริงแล้วเราจะเป็นเพียงตัวละครดิจิตัลเหมือนในเกม The Sims โปรแกรมกาล-อวกาศที่ถูกบูทขึ้นมาเพื่อสร้างตัวเราที่เป็นพิกเซล ,ความเร็วแสงที่มีค่าสูงสุดก็เหมือนกับหน้าจอที่มีอัตรา refresh rate ซึ่งการเคลื่อนที่ระหว่างพิกเซลไม่อาจมากไปกว่านี้ได้, โลกของเราเองก็เป็นดิจิตัล ทุกสิ่งที่ระดับควอนตัมนั้นไม่ได้ต่อเนื่องกันไป รวมถึงเวลาและอวกาศด้วยที่มีความยาวพลังค์และเวลาพลังค์เป็นค่าที่ไม่อาจลดลงไปได้อีกแล้ว, ความพัวพันกันระหว่างโฟตอนที่แม้ว่าจะอยู่ไกลกันแค่ไหนก็ตามกลับเชื่อมโยงกันด้วยอัตราเร็วมากกว่าแสง ในทางกลับกันโปรแกรมสามารถเปลี่ยนพิกเซลใดก็ได้บนสกรีนแม้ว่าสกรีนนั้นจะคือเอกภพของเรา, เวลายืดออกได้ก็เหมือนกับ frame rate ของเกมที่ช้าลงเมื่อเซิฟเวอร์กำลังทำงานหนัก, การสุ่มในโลกควอนตัมที่เกิดขึ้นก็มาจากหน่วยประมวลผลสามารถเลือกสถานะควอนตัมค่าใดก็ได้ให้กลายเป็นวัตถุในโลกของเรา, อวกาศว่างเปล่าที่ไม่ได้ว่างเปล่าก็เหมือนกับ Null Processing, และ อิเล็กตรอน,โฟตอน, คว้ากที่เหมือนกันทุกตัวก็เนื่องจากมาถูกสร้างจากโค้ดเดียวกันนั่นเอง

How can we know if our world is a digital construct or not? One way is to look for tell-tale signs, like pixels, processing limits, channel bandwidths and a system boot-up. A virtual reality should behave like one, so a critical analysis should reveal it. Surprisingly, physics tells us that our world
1. Had a beginning. All the distant galaxies are receding from us at known rates, so it is possible to calculate back when our universe started up13 about fourteen billion years ago, in a first event that began not only our universe but also its space and time. Yet a complete physical universe can’t begin, as by definition there is nothing outside it to create it and to create itself, it would have to exist before it began. This leaves physics speculating on D-branes, alternate universes, wormholes, teleporting worlds, quantum tunneling, big bang-big crunch oscillation theories and other steady state variants. In contrast, every virtual reality has a boot up that creates its pixels and its space-time operating system, based on nothing within itself (See 2.5).
2. Has a maximum speed. In our world, a light shone from a spaceship moving at almost the speed of light still leaves the ship at the speed of light, which is impossible in an objective reality. Einstein proved that the speed of light is a maximum, but gave no reason for it. The equations increase an object’s inherent mass as it increases speed relative to other objects, which works but doesn’t really explain anything. In contrast, every screen has a fixed refresh rate that no pixel-to-pixel transfer “speed” can exceed (see 3.2.4).
3. Is digital. Everything at the quantum level is quantized, including time and space, but field theory assumes continuity, so it has to avoid the infinities that implies by a mathematical trick called renormalization. We think our world has no gaps but actually Planck length and time are irreducible and calculus implies infinitesimals. In quantum realism, pixels and cycles are expected (see 2.2.2).
4. Has quantum tunneling. For an electron to suddenly appear outside a field barrier it can’t penetrate is like a coin in a perfectly sealed glass bottle suddenly appearing outside it. Again, this is impossible for an objective reality although quantum theory permits it. In contrast, a digital reality allows “cuts” between one probabilistic frame (quantum state) and another (Ch5).
5. Entangles entities. Entangled photons maintain opposite spins no matter how far apart they go because quantum collapse works instantly across the universe. An objective reality limited by the speed of light can’t do this, so Einstein called entanglement spooky action at a distance. In contrast, a program can instantly alter any pixel anywhere on a screen, even if the screen is our universe. In this view, entangled photons just merge their processing until the next processing reboot (see 3.6.5).
6. Space curves. In Einstein’s vision, the sun keeps the earth in orbit by “curving” the space around it, but what exactly does space curve into? Space needs another dimension to do this, but string theory’s extra dimensions are “curled up” in our space, so they don’t allow it. In quantum realism our 3D space is a just a “surface” that can curve into a fourth dimension (see 2.3.5).
7. Time dilates. In Einstein’s twin paradox, one twin travels the universe while the other stays on earth, and the first twin returns after a year to find his brother an old man of eighty! In an objectively real world time is fixed but in our world it slows down as we go faster. Likewise, every gamer knows that the frame rate of a game slows down if the server is busy (see 2.4.1).
8. Randomness occurs. In our world, radioactive atoms emit alpha particles randomly, i.e. in a way that no prior physical “story” can explain. Randomness implies a physically uncaused cause that isn’t possible in a complete physicality. The many-worlds fantasy, or today the multiverse, was invented solely to deny quantum randomness. In contrast, the processor of a virtual construct can choose which quantum state becomes a physical state in quantum collapse (see 4.3.1).
9. Empty space is not empty. An objective space should be nothing but our space exerts a pressure. In the Casimir effect, flat plates in a vacuum placed close together experience a force pushing them in. Current physics attribute this to virtual particles created by the vacuum, but space as null processing is a simpler explanation (see 2.5.5).
10. Waves are particles. In Young’s two-slit experiment, one electron goes through two slits, interferes with itself to give an interference pattern, but still always arrives at one screen point. A particle can’t do this but a program can spread instances of itself like a wave but still restart at a point (quantum collapse) to arrive as a particle in one place (see 3.3.5). Processing can spread like a wave but reboot like a particle.
11. Every electron is identical. In our world, every photon, electron and quark is indistinguishable from every other one, just as if the same code generated all of them (see 3.3.5).
12. Quantum superposition. In quantum theory, currents can simultaneously flow both ways around a superconducting ring (Cho, 2000), and an electron can spin both up and spin down – until observed. Such combinations are not physically possible, so in current physics quantum states don’t exist, but in quantum realism an electron program can instantiate its code to explore both options (see 3.6.1).
13. Non-physical detection. Imagine a bomb so sensitive that even one photon will set it off. It should be impossible to detect, but scientists have done the physically impossible with a Mach-Zehnder interferometer (Kwiat, Weinfurter, Herzog, Zeilinger, & Kasevich, 1995). Current physics attributes this to quantum states that don’t exist but quantum realism lets those quantum states exist (see 3.6.4).
14. Retrospective action occurs. If the future can affect the past, causality fails and with it physics. Yet in delayed choice experiments, an observation made after a photon takes a path defines the path it took before the observation. This has led some to speculate that all time, like all space, already exists, allowing time travel and all the paradoxes it implies. In quantum realism program instances take all paths and the observation picks the physical event (see 3.6.3), so there is no time travel.
15. Anti-matter. Quantum equations predicted anti-matter, but no reason has ever been given why matter that inherently exists needs an inverse, of the same mass but opposite charge, at all. In Feynman diagrams, an anti-electron colliding with an electron goes backwards in time, but how it can enter an event in reverse time not explained. In contrast, processing by definition implies anti-processing, and if time is the processing sequence, anti-processing implies anti-time (see 4.3.6).
