      Yes! We believe that the universe is constantly expanding and getting bigger.

      There’s also a common saying that the more you learn, the less you know. That’s because as you keep learning about science, art and history you realize there is so much more information out there you didn’t know about. That’s likely how we will find exploring space- the further we go the more there will be.

      The universe is constantly expanding. We can see this as everything is moving away from each other and the space between them is increasing. Imagine a balloon, and you draw dots on it, as you blow up the balloon the dots move further apart (forget about the fact that the dots themselves get bigger in this case). Now imagine those dots are inside the balloon, as it expands they get further away. A way we can see this is through the Doppler effect, the same way that when an ambulance goes past you you hear the sound change, whether its moving towards or away from you, the same with light!
