Summary:
- This article discusses the possibility that the jets from a celestial object called 3C 273 may be pulsing like a heartbeat.
- The author, Avi Loeb, a respected astrophysicist, suggests that the observed variations in the brightness of these jets could be due to a periodic mechanism, similar to how the human heart beats.
- Loeb proposes that studying the pulsing behavior of these jets could provide insights into the nature of the central engine powering them, which may be a supermassive black hole.
