MLC conjecture

The mlc conjecture is a big question that mathematicians are trying to answer. It asks whether it's possible to color all of the numbers from 1 to infinity in such a way that no three numbers in a row (like 1, 2, and 3) are all the same color.

It's like when you're playing with blocks and you have to put all the same color blocks together. But with the mlc conjecture, you have an infinite number of blocks to put together!

Some really smart people have been working on this problem for a long time, but they haven't figured out the answer yet. It's one of the biggest mysteries in math!
