I got sent this from a year ago, and I am still thinking what was the secret number that they hid a secret from, so here are the pictures.

The first one was a car, and a random equation. enter image description here

The next one looks like a moon from Mars, with a random red circle. The person that messaged these from me said this has a connection with the first picture.

enter image description here

The last image has some text: enter image description here

What is the number, and what do these images mean?

    $\begingroup$ Are you sure that [logical-deduction] applies here? That's only supposed to be used when formal logical reasoning (like grid puzzles, or liar puzzles) is required, not when you think that a small amount of informal logic is involved. $\endgroup$

1 Answer 1


The equation in the first image can be broken out:

µ = micro (International System of Units/SI prefix)
M = mega (International System of Units/SI prefix)
µM + S = MicroMegaS

The first image and second image work together as stated:
The images are a speeding Chevy Volt (on a TEAR?) and the crater Voltaire on the Mars moon Deimos. Voltaire is the author of the novella Micromégas which notably predicts Mars having 2 moons.

Immemorial - originating in distant past; very old.

Searching for immemorial in the text of Micromégas will yield this passage:

We have more matter than we need," said he, "the cause of much evil, if evil proceeds from matter; and we have too much mind, if evil proceeds from mind. For instance, at this very moment there are 100,000 fools of our species who wear hats, slaying 100,000 fellow creatures who wear turbans, or being massacred by them, and over almost all of Earth such practices have been going on from time immemorial.

Taking the 2 numbers from this passage (100,000) and multiplying them together will get you 10,000,000,000 or 1010 (the nth word?)

  • $\begingroup$ Right, just trying to figure out a way to make "the nth word" $\endgroup$ Commented Mar 25, 2021 at 13:33
