Robot: What are you going to do today?
Astronaut: I‘m going to visit the sun.
Robot: But it’s too hot! You’ll burn up!
Astronaut: I’ll be fine. I’m going to go at night.
This silly conversation shows how will and be going to are often used together when speaking about the future. What’s the difference between be going to and will? It all depends on the situation.
In the conversation, the robot asks the astronaut about his plans using be going to. When the robot tells him, “You’ll burn up,” that is a fact, not a plan, so he uses will. Again, when the astronaut replies, “I’ll be fine,” he is making a promise. The astronaut has a plan: “I’m going to go there at night.” It’s not a very smart plan, but it’s a plan, so he uses be going to.
I hope he wears a lot of sunscreen.
