The Next Big Questions in Astronomy - Professor Carolin Crawford

1. That matter and anti-matter were produced with a slight asymmetry (matter>anti-matter) is like Lee Smolin's theory of 'small changes' employing natural selection to explain the evolution of abundant black holes/galaxies (similar to the Darwinian theory of evolutionary changes due to natural selection) that might also explains how 'fine tuning' have been achieved on the cosmological scale.
   Again, Caroline's beautiful account of neutrinos (specially the few big ones so far detected) and the asymmetry in particles and anti-particles, may hold the secret of cosmological evolution.-!!!
2. Ms. C.C. imparts a wealth of information and understanding. I have watched all of her talks... give us more!!!
3. And of course, gravitational waves have already been detected.
4. https://www.youtube.com/watch?v=swYLornsfRc Video I made of the moon showing crater and moon with filters. I am going to be taking footage/photos of jupiter and saturn and more in the near future. I plan to do a lot more videos. Please subscribe if you are interested. I hope you enjoy the video. Thanks guys. Take care. :-)
5. Amazing
6. Excellent.
7. Outstanding! thank you professor
8. meanwhile.. last week...news came out there might be a planet orbiting earth   in-between the size of Neptune and earth  a planet 9  ...way out there   further away than the Oort cloud and the Kuiperbelt..
9. yesterday a new window was opened...gravity :)
10. is it possible for atomic fusion when proto-planets collide? maybe with a requisite large amount of kinetic engery? etc? anyone? or are stars the only way elements can be created past (mostly) iron when they nova?
11. Bravo !!!
    I am struggling to think of a presenter who she isn't head and shoulders above. To the extent that it is distracting how articulate and fluent she is. Lovely voice and accent.
    
    Asolutely no circumlocutions, nary an "um", it is like she has an editor plugged into her brain. She will mispronounce maybe two or three words per presentation and pause for a split second correct herelf and continue. There is no wafling by way of peroration. She just gets to the end and stops. It is quite astonishing. I found myself wondering if there was the makings of a parlour game in nit picking her grammer and delivery al la "Just a minute" except with her it would be "just an hour".
    
    it's just her at the lectern with a bunch of slides but it is riveting viewing. She keeps it accessible but manages to take it right up to the edge of current understanding. Never gussies it up but insted manages to let the subject itself carry the "gee whiz" factor.
    
    Things like sun dogs and all the various hazes and rainbows and all that stuff generally makes my eyes glaze over when it comes to the mechanisms or reflection and refraction but she makes it plain.
    
    I cant think of a presenter to equal her.
    
    ~Wooop Whistle CLAP !!! ~ ENCORE ! ENCORE ! ENCORE ! ENCORE ! ENCORE ! ENCORE ! ENCORE ! ENCORE !
12. If you want to look to the next big question in astronomy, then stop trying to sell the Big Bang Theory. This is a worthless idea and it will never pan out. The Universe is timeless, and endless and until you wrap your mind around this idea, you are wasting your life's work.
13. 51:52 What Professor Crawford is saying here is not correct. The Kepler telescope was designed specifically to detect Earth-sized planets around G-type (Sun-like) stars with an orbit of about 1 Earth year. This requires viewing 3 transits... so 2 to 3 earth years should be enough to catch all of those. Kepler was originally a 3.5 year mission. It made that. And was granted another 3 years. But unfortunately reaction wheel failures (reaction wheels are necessary for maintaining precise camera pointing) ended the primary mission after about 4 years total, in May 2013. Basically, we can detect an Earth. But detecting a Mars is touch and go. The timing would have to be exactly right. But the amount of data collected is tremendous. It's still being processed, I think. And ground-based verification takes time. So stay tuned.
14. Re. Lord Kelvin, as appears in Wikipedia: "The statement "There is nothing new to be discovered in physics now. All that remains is more and more precise measurement" has been widely misattributed to Kelvin since the 1980s, either without citation or stating that it was made in an address to the British Association for the Advancement of Science (1900). There is no evidence that Kelvin said this, and the quote is instead a paraphrase of Albert A. Michelson, who in 1894 stated: "… it seems probable that most of the grand underlying principles have been firmly established … An eminent physicist remarked that the future truths of physical science are to be looked for in the sixth place of decimals." Similar statements were given earlier by others, such as Philipp von Jolly. The attribution to Kelvin giving an address in 1900 is presumably a confusion with his "Two clouds" speech, delivered to the Royal Institution in 1900 (see above), and which on the contrary pointed out areas that would subsequently see revolutions."
15. 16:56 The woman in the cute "cat glasses" is Jocelyn Bell. One in a line of many female scientists, including Rosalind Franklin and Vera Rubin who did not get proper credit for their amazing work until long afterward. Until very recently, it was just business as usual to shift the credit to the nearest male at all involved.
16. I want more! Please return, Professor!
17. This was a great lecture by someone who is passionate, smart and deeply immersed in their subject. A great job by Carolin. This is so worth watching....  Hugh
18. One of the most amazing lecturers I've seen. She's so amazingly saturated in knowledge on her subjects, yet presents them in layman's terms so that anyone can follow along and remained interested.
19. I had forgotten about Jocelyn Bell 16:55.
    In 1974 Lowell S. Brown [quantum field theory] got stuck teaching a small honors class in freshman physics at the University of Washington, and he mentioned her discovery.
    But each of us that stares at charts of numbers, hoping to see a pattern, can relate.
20. She was great. Even though most of what she said was familiar, seeing it all laid out took my breath away.
