1. Fake space… research flat earth.

2. Jo Dunkley makes us all sure, that there is no such thing, as a bad question! Anyway, I enjoyed it so much.

3. Thoroughly enjoy the the RI's Q&A sessions.

4. I enjoyed the Q&A more than the main talk.

5. Jo Dunkley, don’t have sleepless night over dark matter. Ask officially and you will have the answer. come back to tell RI and get your Nobel. I know you won’t. As I told Nobel Loriat, there is no expansion just ignorance like dark matter. Ferydoon Shirazi. MG1

6. Jo dances with the stars…
   Lovely presentation.

7. Great question , something i am currently working on x 1000

8. What universe is growing into question was good, and its answer was brilliant.

   I was also wondering on that question for quite a while.

9. Jo is such a great science communicator! Both the lecture and the Q&A were awesome.

10. On how Georges Lemaitre became in charge of a once reformed science of astronomy.

11. space-time is (mind)bending to say the least… thanks for the insights though!

12. Just brilliant! Thank you RI

13. Hi Jo, please stop saying "That's a good question."
    Every question is a good question.

14. She's a really good communicator. She does a great job of engaging and translating complex topics to lay-personese without dumbing it down.

15. What a clear and enthousiast talk, i am totally in love

16. Utterly fascinating!!!!

17. Love Jo – she rocks 🙂

18. Wonderful personality. Great trade for a science communicator on top of the vast knowledge.

19. she makes me think of "The Sound of Music".

20. A brilliant presentation! A wonderful speaker. I have always felt that the big bang was one in a series of big bangs, which would require the current universe to eventually stop expanding and finally collapse on itself, thus creating a big crunch followed by another big bang. I wonder if there are any who are looking for this scenario.

21. thanks for including the post-talk!

22. Its electrical….every part of this is fantasy based on fantasy. Redshift is wrong, dark stuff is wrong, every part go mainstream cosmology, astronomy is down a very dark rabbit hole and they refuse to come out……money, lots of it….

23. Dark Energy is a regenerating energy field of space. Atoms exploit dark energy and convert it to atomic forces. So atomic forces are variable dependent upon the available energy density of space. Guv gravitational fields represent an space energy gradient.

    Dark matter on the other hand, is caused by variable atomic forces, that is dependant upon variable energy density of space.

24. Time dilation is defined by a modulated rate of force driven systems. Modulate the rate of a force driven system, equates to modulated system forces. Time and forces people!!!!!!!

25. Interesting that science is quite certain that most of the universe is matter and energy that can't be observed but affects it so significantly, but won't consider the possibility of a spiritual reality.

26. Please seek out the basic molecules of dark energy
    Dark energy drives the universe towards rapid expansion
    Dark energy may be stronger than the past
    There is a theory -M is the theory of the eleventh dimension
    Is Dark Energy the Guo of the Eleventh Dimension of the Universe?
    Need a particle collider to detect dark energy particles?
    But how will the dark energy particle be detected?

    Is it dark energy that creates new molecules in the universe?

    We need schemes to detect dark energy molecules

    Is dark energy particles that alienate from ordinary matter?
    Perhaps this aversion is the reason for the expansion of the universe
    We ask you to send my five questions to physicists

27. how can we be sure that space itself is expanding (the elastic stretching) vs galaxies are just moving in fixed space (the blue dots moving on the elastic that doesnt stretch)? if space itself is expanding, then dark energy might not be actual energy but rather a property of space-time much like general relativity

28. If the universe is a computed virtual reality, then what happened before the big bang has no meaning. The computation starts at t=0. The source (programmer and the computer) are outside this "physical" virtual reality, and cannot be known by characters within the virtual reality. Consciousness is fundamental, not the computed "physical" virtual reality.

29. She didn't fully answer the question about the speed of light and time to Neptune. The question was on relativity and actually was pretty good. Neptune is five light hours from earth. If we had a spaceship which traveled at or near the speed of light, would five hours pass for people riding in the spaceship to Neptune or would five hours elapse on a clock on earth? Say the spaceship departed at midnight UTC, at 5:00 am UTC on earth would the spaceship be at Neptune. If so, would a stopwatch on the spaceship read 5 hours? Traveling at the speed of light would slow time down, so less than five hours on the ship would have elapsed. Relativity makes my head hurt.

    I guess listening to it again she did explain it, I just don't fully understand it. Light takes five hours to travel from Neptune to earth *from our perspective on earth*. If you shot a clock at neptune at the speed of light, it would not read five hours when it reached Neptune, but it would take five hours from our point of view, watching it go. I think.

30. Thank you!

31. Thank you!

32. 4:20 start it from there.

33. Wonderful Q&A session. It is a joy to listen to a very well informed Jo Dunkley Thank you.
