Ross's paradox

Okay kiddo, so there's this thing called Ross's paradox. It's a weird and tricky problem that people have been trying to solve for a long time.

So, imagine you have a group of people, let's say 100. They're all trying to vote on something, like what color they want the playground to be. Now, in order for the decision to be made, more than half of the people have to agree on the same color.

But here's the weird part: let's say that 51 people vote for blue and 49 people vote for red. That means blue wins, right? But what if one of the people who voted for blue changes their mind and switches to red? Now it's 50/50, so neither color has won!

But let's say another person changes their mind and switches back to blue, so now it's 51/49 again. But now a third person changes their mind and switches to red again. So now it's back to 50/50!

See the problem? No matter how many times people change their minds and switch their votes, the group can never come to a decision. This is Ross's paradox.

Scientists and mathematicians have been trying to figure out how to solve Ross's paradox for a long time, but it's really hard! It's like a big brain teaser that no one has been able to crack yet.
