Importantly, Loop Quantum Gravity does not predict any signature in gamma ray bursts, though this has on occasion been deliberately or accidentally presented as such. (Thus my comment about carefully not making any predictions.) Besides this, the signature that people have been looking for (are Sabine Hossenfelderhttps://www.blogger.com/profile/06151209308084588985noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-57808549147054915822013-08-04T00:17:06.598-04:002013-08-04T00:17:06.598-04:00Does not the resent observation of ultra high ener...Does not the resent observation of ultra high energy gamma rays contraindicate any discrete structure of spacetime?Stephen Paul Kinghttps://www.blogger.com/profile/12854545182901504082noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-17949205123123975492013-08-03T05:39:24.848-04:002013-08-03T05:39:24.848-04:00Nemo:

It is somewhat beyond me why anybody would want to watch the video if they could as well read the text in a fraction of the time given that the visuals are pretty much useless, but anyway. All I wanted to say is that you can read through the bad-audio passages.

But I have to say I’m a little upset your focus seems to be so negative. The film’s target audience is the educated layman; I think you are mistaken to say that no one will learn anything who doesn’t already know the field.. <br /> I studied astronomy and Anonymousnoreply@blogger.com
