Normal crossing singularity
Okay kiddo, so imagine drawing a bumpy line on a piece of paper. Now, if you zoom in really close to where the line crosses over itself, you might notice that it looks like two lines kind of touching. That's what we call a normal crossing singularity!
It's called "normal" because it's a common type of singularity that happens a lot, and "crossing" because the line is crossing over itself. It's kind of like when you cross your arms in front of you, except the line doesn't have arms.
Scientists and mathematicians like to study these normal crossing singularities because they can tell us a lot about how things work in the world. We can use them to understand things like how cars move on roads or how electricity flows through wires.
So remember, a normal crossing singularity is just a fancy word for when a bumpy line crosses over itself like it's giving itself a big hug!
