Physics approach: Are we all stardust?

“Every atom in your body came from a star that exploded.

And, the atoms in your left hand probably came, from a different star than your right hand.

It really is the most poetic thing I know about physics: You are all stardust.

You couldn’t be here if stars hadn’t exploded, because the elements – the carbon, nitrogen, oxygen, iron, all the things that matter for evolution and for life – weren’t created at the beginning of time.

They were created in the nuclear furnaces of stars, and the only way for them to get into your body is, if those stars were kind enough to explode. So, forget Jesus.

The stars died so that you could be here today.”

― Lawrence M. Krauss, theoretical physicist

Lawrence  M. Krauss is a theoretical physicist  and cosmologist

Meaning that he studies the origins of the universe. He is exploring the most fundamental of questions who we are and where we came from.” In this capacity, together with his scientific writing, he seeks to spread knowledge about the origins, evolution, and history of the universe to a general public.


Scientific Background

Lawrence Krauss is not one to shy away from a controversy, and working to find the origins of the universe can certainly cause some controversies. String Theory Critic: Krauss is one of the most prominent and respected critics of string theory. His 2005 book, Hiding in the Mirror details the history and allure of invoking extra dimensions as a physical explanation, and calls into question whether this is really justified.

Science Writing

Physicists write a lot of academic papers. In fact, according to his website, he has authored “over 300 scientific publications.” In addition, Krauss regularly writes editorials, essays, and articles for popular magazines. He’s written a number of books for popular audiences, making him one of the most prominent voices in explaining the history of the universe to lay audiences.
