Why is the fact that the Antimatter atom is 'measured' for first time so important?

It confirms our theories that they can exist. It means our theories are very good at predicting things.

It's like if you could predict what the next lottery numbers will be with a high accuracy - there's a lot to gain if you know how the world works.

Or a better analogy: let's say you're living in the 1600's. There's no such things as engines yet. And then you suddenly realise there's a way to build one thanks to water expanding when it's heated. And you know this simply because water has predictable behaviour, and you've done experiments. And when you start the car, *it just works*. Exactly like you expected it to. Because you knew everything about the water and the metals and the fire, you could use it to build a car.

Now they're testing the theories for the fundamental particles to see if they predicted everything just right, and if they did we can base new inventions of that knowledge, the same way people could build engines because the theories worked.
