Hi Julie, Come out with the stuff that they do? Please Chris. Give some examples. Some Youtube clips perhaps:) Oops Out of popcorn... |

Hi Julie, Philosophers could also be a bunch of 'outside of the box thinkers' in my opinion.. rOZZ Music Pictures |

...I recall one of my early QM lectures - the lecturer came in pick up his pen and started at the top right hand corner of the white board, and proceeded, without a word, to cover the whole board with equations. On finishing he stepped back, made a couple of corrections, and then said "Ladies and Gentlemen, that is all yo have to know to pass this course, but you still won't be any closer to understanding the Universe let alone quantum Mechanics". I passed his course, but still don't understand the Universe or quantum Mechanics.... LOL... Shut up and calculate.... "Freedom is just Chaos, with better lighting." Alan Dean Foster |

I passed his course, but still don't understand the Universe or quantum Mechanics.... More LOL. She starts with Navier-Stokes equations. In machine maintenance you use them all the times. In that case its how viscosius fluids behave under pressure and temperature. Bearings of all kinds are dimensioned by these equations.

I passed his course, but still don't understand the Universe or quantum Mechanics.... I should like to have a deep meaningful discussion of bearings with HER.....LOL. As Chris noted a long time ago when I first found that lecture. I do find her most enchanting to listen to. Someday I may even actually listen to what she is saying about math.

One woman who diffently deserved a nobel prize is Lise Meitner. She found out how fission reaction works but the prize went to her collegue Otto Hahn instead. Been to her house in Sweden in Kungälv. |

searching 4 ToE is like searching 4 "soul mate"...it might exist, but might not @ all... some principles works so far on different scales...so why not just them as they r & refine them? we've got B practical... ;) non-profit org. Play4Life in Zagreb, Croatia, EU |

Julie mentioned 'aether' earlier. Laura Mersini-Houghton: "An Aether of Time", FQXi Azores Conference 2009. https://www.youtube.com/watch?v=4iGEARcV8ds In order to understand the universe there are so many things to learn that nobody can explain for now. "Simple" things like time, energy and gravity. btw. Max Tegmark is helping her with the microphone:) |

This lady is in a "Physics theory group" at UNC. I presume that her "theories" would have some mathematical underpinnings that would pass the muster of Peer Review. To state that there is no such thing as a black hole may be equivalent to my saying that there is no such thing as an Electron (which I often do). What we both may mean is that we have created a model --which may be fictitious -- in order to explain and control what we see happening. In the case of electricity the equations seem to work very well in everyday discourse--I am not so sure what math comes out of her black hole statements and whether it can be tested physically or at least for mathematical soundness. |

This lady is in a "Physics theory group" at UNC. Her black hole statements? She is speaking of multiverses and how that theory could explain of our universe existance without the problem with the big bang and inflation. And science theories are always peer reviewed. Even the Einstein theory of general relativity is still peer reviewed. There are some flaws in that theory that still needs to be explained. |

Peer review is a step done before publication of an article in a scientific journal.There are two main journals branches, full journal with peer review and letters to that journal without peer review. Now people put on line articles before they have been peer reviewed and sometimes present them in lectures and conferences which invriably end in Youtube. This is not peer review, but it is being done very frequently. Tullio |

It is perhaps not called peer review after publication of an article in a scientific journal when you are reviewing theories but scientist always like to test them. That's what experimental scientists do. Eventually prove a theory is right by observation and make a law:) |

Peer review is done by referees and the process takes time. Often the author(s) of the article is asked to explain or clarify some points before his text is accepted for publication. Meanwhile others may publish their theories without peer review and this brings the problem of priority. This is why many authors publish their article on line with the notice "submitted to".

It happens. I didn't know it was called "submitted to". Main stream media often miss that. And there are also fake theories but thats another story. |

My only scientific paper, which described the results of my thesis, was published in Il Nuovo Cimento, in September 1967, and not in Lettere al Nuovo Cimento. Since I had graduated in February this gives an idea of the time lag involved in publishing in a referred journal. Tullio |

Her black hole statements? Yes this person also published articles in which she denies that black holes exist. They have been roundly criticized by others in the field. |

Her black hole statements? Beeing criticized by others in the field is a part of the job when beeing a scientist. In September 2014, she claimed to demonstrate mathematically that, given certain assumptions about black hole firewalls, current theories of black hole formation are flawed. She claimed that Hawking radiation causes the star to shed mass at a rate such that it no longer has the density sufficient to create a black hole. https://www.google.se/?gfe_rd=cr&ei=H7HfVe6nELKr8wfDhplA#q=laura+mersini But without other scientist examines the work of other scientists science will get lost. Her ideas make sense to me with a multiverse as a landscape. Sometimes due to QM a universe are created like our. |

Hubble telescope has just discovered a double black hole in a galaxy which hosts the nearest quasar. The two black holes orbit each other and will end by merging in a few hundred thousands years. See www.nasa.gov. Tullio |
