Are We Living in a Simulation? A Jewish Lens on a Modern Idea

“Simulation theory” sounds like sci-fi: the idea that what we call “reality” might be generated by an underlying information system—like an unimaginably advanced virtual world. But if you zoom out from the pop culture vibe and ask what the idea is really pointing to, you get something surprisingly serious:

• Is the world as “solid” as it feels?

• Is reality fundamentally “stuff”… or fundamentally “information”?

• If this world is contingent, what does that mean for meaning, morality, and purpose?

Judaism has been asking versions of these questions for thousands of years—using different language, and aiming at different conclusions, but often circling the same core insight: this world is not the ultimate layer of reality, and your choices still matter intensely.

This post gives a concise, source-centered bridge between modern simulation talk and classic Jewish metaphysics—without pretending one “proves” the other.

1) What “simulation theory” actually claims

The most famous academic formulation comes from Nick Bostrom: if advanced civilizations can create vast numbers of realistic “ancestor simulations,” then statistically it becomes plausible that we might be in one. It’s a probability argument, not a lab-tested fact.

A key point: even if the world were “simulated,” that wouldn’t automatically make it meaningless. David Chalmers argues that virtual worlds could still be real in the sense that experiences, relationships, and moral choices remain genuine.

So the serious version of simulation theory isn’t “nothing matters.” It’s more like:

Reality might be implemented differently than we assume.

2) Why scientists keep drifting toward “information”

Even outside simulation hypotheses, modern thought keeps bumping into information as something foundational.

• John Archibald Wheeler famously pushed the “it from bit” intuition: physical reality may be deeply tied to informational structure and observation/measurement.

• Eugene Wigner highlighted the mystery that mathematics describes the universe with unsettling precision.

• Max Tegmark goes even further, proposing that reality is a mathematical structure (a controversial but influential view).

You don’t have to accept any of these to see the pattern: the deeper we go, the more “reality” starts sounding like structure, law, and information—not just “stuff.”

3) Judaism’s core move: this world is real—but not ultimate

Judaism doesn’t need simulation theory to say the world is layered.

A) “There is nothing else besides Him”

A foundational verse is in Deuteronomy: “Ein od milvado”—there is nothing besides Him. In many classical readings (especially in mystical and Chassidic thought), that’s not just anti-idolatry; it’s a claim about radical dependence: nothing exists independently of God’s sustaining power.

That’s not “we live in a computer.” But it is a strong metaphysical statement: reality is contingent and upheld.

B) This world is a corridor

Pirkei Avot frames this life as a prozdor—a corridor before a deeper “banquet hall.” Translation: this world matters, but it’s not the final layer of reality.

C) Accountability is total

That same tradition also says: an Eye sees, an Ear hears, and deeds are recorded. The point isn’t surveillance paranoia—it’s moral seriousness. Your actions count.

Put these together and you get a worldview that sounds oddly compatible with the best, non-nihilistic reading of simulation talk:

The world is not ultimate, yet responsibility is ultimate.

4) “Continuous creation” sounds like “continuous rendering”

One of the most striking overlaps is not gematria or quantum. It’s something Jews say every day.

In the daily liturgy (before Shema), we describe God as renewing creation constantly—creation is not only a past event; it’s an ongoing sustaining act.

In simulation language, you might call that “continuous rendering.” In Jewish language, it’s something deeper: God is not a distant watchmaker—existence is being upheld right now.

Again: Judaism is not claiming computer code. It’s claiming dependence, renewal, and intentionality.

5) Torah as “blueprint” (and the limits of the analogy)

Mystical tradition famously describes the Torah as a blueprint through which creation is structured. Zohar uses language that many interpret in that direction: the world isn’t random; it’s ordered through a prior wisdom.

In modern terms, people may be tempted to say “Torah is code.” That can be a useful metaphor—but it’s important not to overclaim. The Torah isn’t a programming manual. The point is:

Creation has structure, meaning, and moral direction—not chaos.

6) A dramatic case study: authority “inside the system”

One rabbinic story is especially relevant because it addresses a question simulation theory often triggers: If there’s a Creator, do humans have real agency?

The “Oven of Achnai” narrative in Bava Metzia depicts a halachic dispute where miraculous signs appear—yet the sages insist legal truth is decided through the Torah’s rules, not by supernatural interruption. The principle invoked is: “It is not in Heaven.”

The philosophical punch is enormous:

• There is a Creator.

• And yet the Creator designed a world where human responsibility and decision-making are real.

That’s not a “simulation proof.” It’s a deeply coherent view of agency within an authored structure.

7) What not to do (if you want serious readers)

If you want to speak to atheists and scholars without losing them, avoid these pitfalls:

• Don’t claim physics “proves” Judaism. It doesn’t.

• Don’t overstate quantum mechanics as “consciousness creates reality.” That’s one interpretation among many, and many physicists reject it.

• Don’t treat gematria correlations as evidence. They can inspire wonder, but they’re not academic proof.

The strongest bridge isn’t “gotcha proofs.” It’s conceptual integrity:

Judaism has a mature metaphysics of dependence, meaning, and accountability that stands on its own—and modern “information-first” thinking makes it easier for contemporary minds to hear it.

8) The practical takeaway: play the world like it matters

Here’s the message that can inspire Jews worldwide and remain respectable to skeptics:

Even if reality is deeper than we perceive—whether you call that “simulation,” “information,” or “createdness”—the ethical demand does not weaken. It strengthens.

• If this world is a corridor, don’t panic over illusions.

• If deeds are recorded, don’t live carelessly.

• If reality is sustained, don’t live ungratefully.

• If God is One, don’t fragment your life into “spiritual” and “real.”

Judaism’s claim is not “this world is fake.”It’s: this world is entrusted to you.

And that’s exactly the kind of message that can meet modern doubt without flinching—while still lighting a fire in the soul.
