  No, but I have friends who are scientists that study this. They look at samples of asteroids, which are rocks that were made the same time as the Earth and the other planets. By studying the afferent types of rock and how old they are, they can figure out what happened 4,500 million years ago when our Solar system formed.

  That depends what you mean by the world! I haven’t ever done an experiment on how the planet Earth was made. But I spent a summer working for the Large Hadron Collider, which recreates what it would have been like just after the Big Bang, when the whole Universe was made!

  That’s what I do for a living 😉
  
  No seriously, when we are probing nature’s building blocks, we are actually trying to find out how the world was made. For example, we know that over 70% of the universe is made of what we call “dark matter”, which we have not seen. We hope LHC can help us find what these dark matter is made of.

  I haven’t, but I have tried to understand how our Sun formed. This would help us to understand how the Earth formed because we think the Earth formed out of the leftover material from when the Sun formed.

  I haven’t but they would be pretty cool experiments I’m sure! I work on a lot smaller things in size like how embryos are made 🙂
