Positive energy theorem
Okay, kiddo, so there's this thing called the positive energy theorem. It's like a rule that says something really important about the energy around us.
You know how we feel energized when we play or do something fun? Well, everything around us has energy too, even things we can't see like particles and waves. And the positive energy theorem says that all the energy around us can't be negative - it has to be positive or zero.
Now, why is that important? Think of it like this: if you owed someone money (negative energy), and you couldn't pay them back, that would create a big problem. But if you had enough money (positive energy) to pay off your debts, then there's no problem.
The positive energy theorem is like that too. It helps scientists make sure that the energy in our universe doesn't get all messed up and cause problems. It's like a safety net to keep everything in balance - positive and happy, just like we want to be.
