TQ3:Echoes from the Abyss: The Mind-Bending Science Behind the Strange Sounds of Black Holes

Описание: #blackhole #physics #echo #universe #gravity
Time before Space brings you the third interview of the Ten Questions(TQ) series. In this interview, I ask Prof. Niayesh Afshordi (Department of Physics and Astronomy, University of Waterloo and Cosmology and Gravitation group, Perimeter Institute for Theoretical Physics (PI)) about his recent work on the echoes from black holes.

00:00 Time before Space presents
00:15 Q1 Why is the event horizon of a black hole so fascinating for Physicists?
01:51 Q2 How is black hole evaporation related to quantum tunneling and dark energy?
04:14 Q3 What are the echoes from a black hole?
05:33 Q4 What is the theoretical motivation behind these echoes?
08:49 Q5 How are these echoes related to the information paradox and scrambling of information?
12:33 Q6 What is the general time interval between these echoes?
13:30 Q7 How do these echoes help us in understanding the theory of quantum gravity?
14:51 Q8 How does one experimentally investigate these echoes?
16:13 Q9 What is the black hole seismology program?
17:51 Q10 What advice would you give to our young audience?
19:15 End
