In mid-20th-century cosmology, there was a debate over the origin of the chemical elements. Some thought that they could be produced in the Big Bang, while others argued that they were made inside stars. The truth turns out to be a combination of both, with additional complications layered in. Some of the elements of the periodic table come all the way from the Big Bang, but others are made inside stars or in stellar explosions. But still others are made by cosmic rays or when neutron stars and black holes merge together. We talk to nuclear astrophysicist Sanjana Curtis about all the different ways that the universe is cleverly able to produce various elements.

Sanjana Curtis received her Ph.D. in physics from North Carolina State University. She is currently a National Science Foundation postdoctoral fellow at the University of California, Berkeley. Her research involves nuclear astrophysics, especially the production of heavier elements in supernova explosions and neutron-star/black-hole collisions. She is also active in science communication, including at her TikTok channel.

0:40.1 | Hello everyone welcome to the Mindscape podcast I'm your host Sean Carroll. I don't know how many of you remember or have this recollection, but back in the early days of like blogging and social media, there was this question of whether or not there was still a place |
0:55.6 | for science journalism in the world, since after all you had scientists who could now just |
1:02.1 | start up their blog and talk about whatever it is they wanted to do. |
1:06.0 | And the answer is yes, you still do need science journalists and you need political |
1:10.3 | journalists and legal journalists and economic journalists, you need journalists who are experts in what they're doing. |
1:15.2 | If only because professional journalists have an obligation to be fair, to think about everything that is going on in the field they're covering and |
1:26.4 | explain it to the people who are reading or watching or listening in an unbiased, |
1:31.9 | overarchingly fair way. |
1:34.0 | Whereas the individual researchers, they're going to talk about what they personally think is cool. |
1:39.0 | So in fact, I think you need both. |
1:41.0 | It's great to have professional researchers being able to reach broad |
1:45.2 | audiences in whatever way they can. You also need professional journalists to set a wider stage and make sure that nothing falls between the cracks. |
1:56.3 | So I say this because I am a person who is a professional researcher, but I also have public outreach, public facing aspects of what I do, including this |
