The atoms created at the birth of the universe came together to form stars, and then supernova explosions created elements such as gold and uranium, which again spread out into space.
The Earth and our life were created from atoms, which are fragments of stars. Atoms also produce energy and forces such as radiation.
You can learn about these as if you were looking at a picture book.
There is also a fog box where you can see radiation, and a nuclear quiz corner as well.
