"ninety percent of everything is crap."
~~~~~~

1) 8-years old girl looks promising to me. She is unlikely to become an advanced physicist, but she is likely to grew up into a smart professional in whatever area she will chose.

2) 16-years old girl is a gymnast that would just marry a tech dude she would meet in that tech field she chose. Then she will live happily ever after.
Or, perhaps, she would become a middle-manager or go into sales.

3) The Chinese student - does not get physics. She may become somebody's assistant though.

4) Phd Candidate - is enthusiastic, but a bit sloppy with the understanding of the physics.
Instead of saying that "gravitational collapse [into a neutron star] causes Supernova explosion" - he is stating much more boring and partially incorrect statement:
~~~~~~~~
https://youtu.be/QcUey-DVYjk?t=1176
So, when a star dies, if the star is massive enough, there's a huge explosion, called a supernova, and the stuff that's left behind that doesn't get blown away collapses into a tiny compact blob called a neutron star.
~~~~~~~~
That statement implies that:
- Supernova explosion may result in the whole stuff to get blown away completely (without a neutron star forming in the end). [That is not true]
- Neutron star forms after supernova explosion. [That is not true, because a neutral star forms before the explosion, not after].

Another sloppy statement from this Phd Candidate:
===
https://youtu.be/QcUey-DVYjk?t=1225
A black hole is sort of like a neutron star's big brother.
===

But, actually, a black hole does not have to have a neutron star inside. A black hole just needs to be massive enough to prevent light from escaping.

Then a piece of crap from Janna Levin:
~~~~~~~~~~
https://youtu.be/QcUey-DVYjk?t=1252
The event horizon of the black hole forms, which is the shadow, the curve that's so strong that not even light can escape.
~~~~~~~~~~
A curve of a black hole is "strong"? Really?

Then this crap:
-----
https://youtu.be/QcUey-DVYjk?t=1236
it collapses to a black hole, and those are so dense that space-time breaks down.
-----
What does "space-time breaks down" even mean?

Then Janna continues:
========
https://youtu.be/QcUey-DVYjk?t=1265
the star's gone, that black hole is empty.
========

That means that Janna does not understand:
- That mass causes gravity.
- What "black hole" is.

5) Matthew Kleban flirted with Janna in this interview and otherwise had fun in this conversation.
Matthew is, clearly, smart and did not to say anything that would be clearly wrong. But he also did not say anything practically insightful.

Summary:
Janna Levin produced show that is fun. It just does not have much to do with actual Physics as a science.

> creating stronger spacetime curvature and often being literally bigger.

Are you saying word "stronger" means "bigger"?

> And "brother" because they are born in very similar processes.

Yes.
A very similar process to a neutron star -- is another neutron star.

But black holes and a neutron stars - rely on different properties of gravity:
1) Black hole relies on ability of the gravity to "capture" light.
2) Neutron stars rely on ability of the gravity to keep neutrons together.

But this Phd Candidate failed to contrast that in his explanation, and instead mixed them together in his "big brother" misconception.
Which suggests that this Phd Candidate misunderstands what he is researching at some basic level.
