Victoria Kaspi Public Lecture: The Cosmic Gift of Neutron Stars

About | Information | History | Online | Facts | Discovery

1. Physics is yet to explain the fact that all celestial body have a magnetosphere and are encased in a cloud of electrons. Even the flat galaxies have a spherical encasing of electric field. Mathematics of these observations may hold/explain reality rather than the 'everything from nothing' theory.
2. Great lecture, thanks.
3. Starting at 44:05 You got me, there. How does the magnetic field from the one pulsar eclipse the other one? I thought magnetic fields don't bend light. (?)
4. after viewing, have the urge to again watch Darren Aronofsky film "The Fountain"
5. At every one of these lectures you get that retarded kid in the back asking stupid questions--lol.
6. 29:20 is an E, not an F#...
7. This is a great talk. I've always been curious, though, can any one tell me how is the magnetic field generated in a neutron star?
8. The director was such a dick.
9. Fantastic mix of content and presentation.
   I liked the questions too. The too smart children were great, their curiosity and subject insight are very much needed for the future successes of cosmology.
   
   I could stand a little more math/equations. After following neutron star shows on YT, I ache for just a little more depth - but not too much because of math. I was able to pass diff-eq and assorted numeric analysis courses with comprehension. I know asking for a little more meat probably results in a side of beef. Still on my fave and rewatch list.
10. Is there a measurable effect from the pressure of the beaming radiation upon the other pulsar in a binary? Just wondering.
11. Warning!!! Yet another Doppler shift explanation from 33:38 through 35:04. If you are close to reaching your Doppler shift explanation limit, you might want to skip that segment.
12. Skip to 2:43
13. Very clear and understandable even to a laity such as me. Thanks.
14. I think it's pushing it to say that the artist's impression is an accurate depiction of a neutron star; for one thing you wouldn't expect to see a few discrete magnetic field lines would you?
15. I can honestly say that the 'music' at 30:30ish was just beautiful.
16. 7 days before the gravitational waves discovery was announced
17. At 42:45 : "We don't know if General relativity is gonna work there".
    Well, sorry to contradict but we do. Because of LIGO. On sept 14 2015, LiGO Scientific team observed what seemed to be gravitational waves from the collapse of two black holes. And black holes DO produce extreme gravitational fields! It was so identical to theoretical predictions that many thought it was a simulation. Also, some suspected it was one of those artificial stimulations of the mirrors that technicians use regularly to calibrate this gigantic instrument. Aftyer an extremely careful study, the team announced on feb 11 2016 that they actually had observed gravitational waves. And those waves and the movement of the stars they imply are EXACTLY as described by Einstein a century ago, within instrumental error. (Reference : Nature, feb 18 2016, pages 261/262.)
18. I'm thinking if the surface of a neutron star is moving faster than light, light cannot interact with the surface. it cannot escape the surface it cannot reach the neutron surface form beyond and would it even be visible?
19. The last question .. i am listening to a talk on Neutron Stars because I want to know about Neutron stars ... if I wanted to know about social science i would find a talk on that .. just a wasted question opportunity in my humble opinion ...
