If nothing can escape from a black hole Then would the jets also be sucked into the black hole or does this mean that something can escape a black hole?
-
is there any interesting books you recommend on reading?
-
X-rays is the name given to rays with unknown properties. What is ment are Roentgen rays.

well said my space and science loving friend! I love the show, and the info...keep up the great work!

Science and exploration should not be dictated by artificial human created limits such as money.
It really irks me we moronically and stupidly limit and delay scientific progress like this. We need another war to motivate the dumb politicians. They even refuse to listen to scientists telling them global warming is an issue. "No, that's not true. We know better than the scientists"
JWST : Lets just hope some americans do not mix up the metric and imperial system again. I do hope Lockheed Martin is not involved in JWST.
This is what happens when you are stubbornly sticking with the old and the outdated thinking.
America should have switched over to the metric system years ago.
America have been very stubborn and uncooperative with the rest of the planet for years. Using the imperial system is just one of those things that have caused delays in technology and progress. Petty politics, megalomaniacal thinking and self-interests are other things.
Humans fighting amongst themselves not realizing we are all on the same side with common goals. -
I like to think of myself as a cynical man, but these videos get me excited. Fascinating ideas, communicated in layman's terms. One could never get bored of Space news, with all the new discoveries and possibilities.

Mesmerizing talk as always!
-
Double thumb up for great commentary.
-
This Is A GREAT Astronomy Video !!!!!!!!!!!!!!!!!!!!!
-
Thanks. It is passion like yours that keeps others' lifted. Great Video.
-
I love astronomy, orbital maneuvers, relativity, rocket propulsion, and the origins of the universe. I just finished year nine at high school, and was wondering what options I should take in year 11, and What careers are possible in these areas? Could anyone please tell me?
-
Having read the comments below, I am completely in awe of the contributors whose debates are extremely stimulating. I love science, but I'm not a scientist so I don't feel I can add anything to these opinions, speculations, etc. However, I can just enjoy the sensation of thinking about the wonders of Space and its many mysteries. Thank you.

How can black holes have jets when even light can't escape from the event horizon?
-
I agree with you Tony, another great episode. BTW can you make a bibliography of your science books and post it in your channel? I can read some of the titles and they look interesting.

"Our Great Observatories" are, compared to what we could have, dim granny spectacles covered by dust. And better orbital observatories, especially occulted ones behind Earth and the Moon, will require man to maintain them. It will be a long time before we will (I said "will", not "can") build robots as capable as a man, his hands and mind can be.
-
love this.
-
Another thing.
If black hole have something "infinite" inside how we can even talk about "normal" black holes, big black holes and "super massive" black holes? How we can say that some black hole have weight of 2 million solar masses if inside is infinite? We should say then black hole with "infinite" solar masses.
I read that our universe contain 10^80 particles, atoms. So how black holes can be infinite? So our universe have 10^80 particles or infinite particles?
-
Light cant escape from black hole but some jet can? Its contradiction. Besides special relativity forbids infinite density right? So how black holes are possible?
:( -
Black holes and Dark matter ? Proven ? I think speculated is a more accurate term.
