What is Firewall of intense radiation and matter?

A firewall is like a super strong wall that stops things from getting through, especially when those things are really hot or moving super fast.

Imagine you're playing with your favorite toy inside a room, and suddenly, something super hot and fast comes rushing in. That’s what happens near some stars, they send out intense radiation (like invisible heat) and matter (tiny pieces of stuff that zoom around). A firewall is like a superhero wall that stops all that from getting to the other side.

• It blocks hot stuff: Think of it like a really thick blanket that stops the fire from burning through the room.
• It blocks fast stuff: It’s like a big net that catches the tiny pieces flying around, they can’t get past it.

In real life, scientists use firewalls to protect spaceships or planets when they're near super hot and powerful stars. It's like having a really strong door that keeps everything wild outside from coming in, so you can keep playing with your toys safely!
