Are atoms immortal?

Answering your questions about life, Earth and the universe

Atoms are the building blocks of our world. Many have been around since just minutes after the Big Bang created the universe nearly 14 billion years ago. And if life on Earth is made of atoms that are from all the way back then... will those atoms keep existing forever? That’s what CrowdScience Listener Rob in Australia would like to know.

Caroline Steel investigates whether it’s physically possible for atoms to survive the test of time. She speaks to physicists looking at the tiniest objects in existence to try and answer some massive questions. What happens to atoms in extreme circumstances out in space? If large atoms can decay to become smaller atoms, what happens to hydrogen, the smallest atom of them all? And how exactly was a combination of these tiny, long-lasting atoms ever able to create life on Earth?
