Strange screen of colors appears over Monterrey, fueling simulation claims

A user shared images of a rectangular structure of colors over the sky of Monterrey and presented them as proof that we live in a simulation. There is no independent verification of the phenomenon, nor evidence that it is anything other than an optical effect or a hoax.

The post that has been circulating on X these days is brief and dramatic: a warning with siren emojis, capital letters and the word «ATENCION» (Spanish for "attention"). Below it, the claim that some images show "an unusual visual phenomenon" in the sky over **Monterrey**, in **Nuevo León**, Mexico, and that an "enormous rectangular structure" appears to be projected over the city. The leap from there to the simulation is not made by the tweet with data, but by the format itself: an account that presents itself as a citizen watchdog and a visual package that begs to be shared before it is checked.

## What is seen and what cannot be verified

The images describe a screen of colors shaped like a rectangle suspended over the horizon. There is no measurement in the material, no time stamp, no reference to an observatory or a weather authority. Nor a second source confirming the sighting from another point in the city. Without that, what remains is an image with no chain of custody.

## The price of believing in the simulation

The simulation hypothesis has an economic problem before a philosophical one: if the world were an artifact, someone would be paying the bill. And there is no trace of that expense. What does have a verifiable cost is the hoax: every unverified sighting that gets shared moves attention, and attention is the asset that gets monetized on social media. The business is not in the sky over Monterrey, it is in the click.

## Why these phenomena go viral so fast

A rectangle of colors over a city is a perfect image for mobile: it is understood in a second and requires no context. That immediacy is also its evidentiary weakness. Optical atmospheric phenomena exist and are documented, but they are confirmed with instruments, not screenshots. As long as there is no independent measurement, the Monterrey screen is an image without an explanation, which is not the same as proof.

If this concerns you because it might signal something real, check local weather or astronomical sources before accepting any sighting as fact.
