Quasars: the Brightest Black Holes - Professor Carolin Crawford
About | Information | History | Online | Facts | Discovery
Quasars are among the most dramatic objects anywhere in the cosmos. They emit prodigious amounts of energy, all due to a supermassive black hole at the heart of a galaxy. Visible far across the Universe, quasars can be used to trace both the early life of galaxies, and the properties of the intervening space. The transcript and downloadable versions of the lecture are available from the Gresham College website: http://www.gresham.ac.uk/lectures-and-events/quasars-%E2%80%93-the-brightest-black-holes Gresham College has been giving free public lectures since 1597. This tradition continues today with all of our five or so public lectures a week being made available for free download from our website. There are currently over 1,500 lectures free to access or download from the website.

Great stuff. The super massive black holes in the early universe are very intriguing.
-
Impressive

these people sit in the office not in the lab. they are a sad joke and a shame for humanity. 100 years of endless stupidity. acosmology of fairy tales. if you search for some meaning in life check out "thunderbolts.info" for explanations that actually mean something
-
black holes don't exist

Very informative! A great teacher, this one.

Carolin Crawford is superb. I understood every word she said. I was on the edge of my seat, eagerly lapping it all up.
I just wish she had spend a bit more time explaining what happens to the rest mass energy when something falls into a black hole. She explains it all like an adventure story.
Also she pronounces so clearly. no ums, no "I means". Every word is clear and to the point. She is the sort you would like to be marooned on a desert island with. -
sometimes so good that they confuse themselves lol

NASA Satan master of deception.... the flocking mind.... lol
-
but to be honest when i saw what power there was behind such beautiful universe, i lost all interest in it.... That it was only as Nasa said it was, then it didn´t no longer meant anything to me.... And still doesn´t... ;)
-
i know some loves to play with that ionosphere, one day they make one step out of tune..... You don´t do that with such huge energy..... :)
-
some might say Australia is all Gamma gamelion around year 2060.... lets hope mick dundee isn´t all dead yet.... ;)
-
a feynmann wrote to me, then i asked aren´t you dead? then the person said yes i was just trying to raise some spirit lol what to say to such person lol
-
NASA is so antenna concerning our solarsystem theese days lol.... One day we can´t dismiss G_D said through particles... lol FAP FAP FAP
-
she sounds so NASA, that it is close to be hot ** miss blue
-
Great lecture.
-
Praise is all very well but a little criticism is required to provide a rational balance. The comment that the center of the Quasar is a black hole is a rather rash statement . For this to be true then the tremendous light source must be outside, by a fairly large margin, of the event horizon and this light source then requires some sort of explanation or at the very least a working theory.

Check out Primer fields ; by David Lapoint on youtube. The universe is electric and magnetic.

I am always amazed that someone could watch this and dislike it. Phenomenal lecture that I will watch many more times. Quasars are creeping into my favorite celestial object, which is currently occupied by GRBs.

Hawking radiation at the event horizon, magic stuff Carolin, keep these videos coming... please.
