Reconstructing the Universe: Theoretical Possibilities and Limitations

If we were to delete the known universe but preserve the laws of physics and an advanced supercomputer, could we recreate it?

This question is a fascinating intersection of theoretical physics, computer science, and cosmology. To explore the feasibility of such an endeavor, we must first understand the limitations of current computational technology and the fundamental principles of the physical universe.

Limits of Simulated Worlds

One of the key limitations of any supercomputer attempting to simulate the universe is that it would only create a digital representation. This digital world is a mere approximation and lacks the physical reality of the universe itself. As the surrealist artist René Magritte famously depicted in his work, “The Treachery of Images,” an image is not the object it represents. This digital universe, made of data and bytes, has no mass and cannot interact with physical beings in any meaningful way.

Imperfect Simulations

Another serious challenge lies in the accuracy of the simulation. Even if we attempt to create a perfectly detailed digital universe, we would still face numerous obstacles. For instance, the supercomputer would need to simulate not just the universe we know, but also a perfect copy of itself and all other supercomputers and brains in existence. This would require unimaginable computational power and could fill up the memory banks of the simulating supercomputer, leaving no room for additional details.

Finite Time Steps and Incomplete Simulations

Every digital simulation operates in discrete time steps. For example, if we start with time t0, the next step would be t0 Δt. No matter how small the time step Δt is, it will always be a non-zero positive number, meaning we would inevitably skip over an infinite number of intermediate states. This makes the simulation incomplete and not perfectly smooth, thus reducing its accuracy. It is akin to viewing a series of still frames in a flickering movie, rather than the continuous flow of reality.

Debates and Counterarguments

Some argue that the situation changes if we are not deleting the universe but merely the multiverse. Deleting the entire multiverse would mean destroying all possible universes, including our own. However, if we aim to recreate just our own universe, the concept of becoming the ultimate creator or creator of reality emerges.

The Role of Supremacy in Reality

Considering the potential of such a supercomputer, we would indeed be striving to control time and space, matter, and the fundamental laws of physics. Achieving this would mean transcending the normal laws of physics and potentially reaching a state of supreme control over reality.

The question then becomes one of whether our computational capabilities have reached the point where we could even theoretically execute such a task. While current technology is far from capable, the very concept challenges us to consider the limits of our understanding and the capabilities of our future technology.

Conclusion

In summary, while deleting the universe and preserving its laws and data might seem like a step towards recreating it, the practicalities of simulation and the constraints of our current and future technologies create significant barriers. The pursuit of such a goal, however, opens up new avenues for exploring the nature of reality and the limits of what we can achieve with our evolving technology.
