Is it possible that X and Y are uncorrelated but X can significantly predict Y? I was just wondering is it possible that X and Y are uncorrelated but X can significantly predict Y?
If so, how would you explain and interpret that?

Correlation measures a certain kind of relation (usually linear) between variables, but other relationships (nonlinear) are possible as well. This is discussed in depth in the Why zero correlation does not necessarily imply independence thread. So it is possible that there’s a non-linear relationship between the two variables, that makes them non-independent, yet it is not measured by correlation.
