And we perceive this effect as the mutual attraction of bodies – gravity. This is what Albert Einstein taught us, and so far, nothing indicates that he was wrong. We curve because we have mass (not to be confused with weight), although gravity is not only about mass. – The source of gravity is not simply mass, but a more general concept: energy density – explains astrophysicist, Prof. Tomasz Bulik from the Astronomical Observatory of the University of Warsaw. Energy density can come from various sources, such as mass, electric or magnetic field density. To make it better: the curvature of space also has its own energy density and is a source of gravity in itself. Prof. Bulik has been involved in gravitational wave astrophysics for years. In the episode, he reports on the progress in this field – and this is considerable, because we can talk about recording dozens of waves per year. Thanks to the development of this branch of astrophysics, we will be able to better understand the interiors of neutron stars, as well as learn details from the very beginnings of the existence of the Universe. The scientist talks about plans to build more underground, orbital, and even Moon-based gravitational wave observatories. You will also hear, among others: about gravitons: hypothetical particles analogous to photons, which, however, instead of electromagnetic interaction, would transfer gravitational interaction. We talk about whether we should protest when our children are taught Newtonian gravity in schools, and also about whether Einstein himself will one day have to be corrected. There are also a lot of questions (thank you!) from Patrons of Radio Naukowe, whom I have previously warned about the planned recordings on the FB group. I highly recommend it! ???? I recorded the conversation in the RN studio, which I was able to set up thanks to the support at https://patronite.pl/radionaukowe Thank you very much! We have further development plans, if you want to help with them - I encourage you to donate in any amount ???? 00:00:00 - 00:01:31 Introduction 00:01:31 - 00:09:00 What is gravity?
