What a time to be alive, when River Song herself gives a lecture about black holes!

how have i never heard of Janna f'ing Levin? she's an electrifying speaker, and on my favorite subject too.

yeah she's great. I've been following her for quite some time now because she helps me understand these insanely difficult concepts and you're right she is a brilliant speaker.

she's such an incredible speaker. i had tears in my eyes listening to her explaining the ligo discovery of black holes. just the immensity of it all. how long ago, how far away, how brief an instant it all took in the end. oof.

Literally, Jana is my favorite

In reference to hearing black holes i would theorize you would feel it more than hear it. As even though it is vibratinging in the hearing range the space your ear occupies would also get stretched and compressed. But that vibration going through your body. Maybeeee again your persepective is also vibrating.

Lol I think maybe her mic is real good it just captures her voice. I refuse to believe no one laughed at her amazing jokes 😂😂

Not everyone laughs loudly enough to be picked up on the speaker's mic, which also does not register those who only smile. Additionally, although the Danes and Scandinavians in general are quite talented when it comes to English, and this particular audience perhaps even more so, let's keep in mind that she was speaking to an audience in a country where English is not the mother tongue.

When talking about Black Holes, how can there be "nothing there" and at the same time have 4 million times the mass of the sun, like what

Right. She made an error when she mentions that even the mass of the downfalling objects is lost, thereby violating fundamental laws of physics. The mass is added to the BH‘s mass, which results in a slightly larger event horizon. What really might be lost is the quantum type of objects, but this is still currently discussed, I believe.

Great talk:-) but, the title of your book is a terrible bait and switch scheme

Just a thought that the pure force of a black hole is like a partical magnet it only absorb particles of pure space which is nothing the clean pure empty space and the curve we see are particles and atoms that do exist broken apart and separated from one atom to another and is absorbed into the black is just the nothingness cleaned from any atom or partical which we as humans can see even with the inventions created by humans a dark space with super tiny almost like diamond particals which are just atoms and particals being pulled in towards this black hole and the tiniest particals left that is a solid partical or atom that has been sucked dry of any of this pure clean natural space which atoms and particals need for atoms and particals to be able for an atom to stick to each other of its pure solid atom or partical of its same kind thus creating a force suction and exuast beacon that can be seen of these particls the size of planets orbiting the black hole till its pure space is taken in towards its natural kind and other particals and atoms are forced out at speeds un imaginal speed and as these particals shoot our tu

that is not a black hole what astronomy is referring to, are often quasars. black holes don’t occur randomly in the sky but always at the edge of a solar system. other than a huge gravity pulling to the black holes, they are not observable but until the end of the life of a black hole when gets clogged with carbon particles and these particles can be observed in refraction. what you see are often the phases of quasar when the stellar mass in the center of a quasar building the star gets consumed and reorganized, never a black hole. black holes occur only when there is a drop of materials from a solar system opposing the gravity of the star at the edge of the aphelion and, gravity from other systems are pulling the material away help the black hole organizing into a vortex. black holes are part of the design of recycling the elements in order to build new stars...when the new star is born after its quasar at the delta of a black hole, the gravity drop in the place the black hole was will exist but never reorganizes into a black hole and gets disabled. i hope it helps.

Quasars are produced by million’s or billion’s, most often billion’s of solar massive black hole’s at the center of massive galaxies. Many billion’s solar massive black holes create quasar’s.

Black holes don’t only form at the edge of a solar system??? Where did you get this information or idea?

Star’s never create quasars. Never. They do not have anything near the amount of energy required to form a quasar. Research more on quasars from reputable sources.

Sorry the entire comment is pseudoscience in my opinion. Those are your idea’s and not what science has taught us through the evidence discovered on the subject.

Black holes are places not objects? this is completely wrong. No they are not places they are objects. They are not holes. They are the most densely packed objects in the universe. And there is no space there, its completely filled with matter to the point of structural maximal allowed density of universe.

what she means is the original star (an object) has collapsed to a singularity behind the event horizon and is effectively gone from our accessible universe. the black hole, defined by that horizon, is essentially the set of spacetime coordinates which are now segregated from the rest of the universe. colloquially, a place.
