My favourite thing about science is that there is no end. There will never be an end to finding new things out about the universe, at least not for generations and generations. We are still learning about our planet, which is a very small speck of dirt in a huge universe.
From the first time we started thinking about fire, growing crops and using wheels, we have built a huge amount of knowledge. We know lots and lots of things as a species. However, we still don’t know everything about the ocean. Nor about the past, or the future, or our solar system, or anything further out. There is so much more to find out.
