The universe is putatively expanding but it is not expanding into "something" There is no other "something", only what is currently existing. Think of a spherical balloon surface. This is 2 dimensional--assume a 2 dimensional world --it expands as it is being inflated by creating more 2-dimensional surface area. There is no 3rd dimension in a 2-dimensional world just as there is no 4th dimension in a 3 dimensional world. How about the supposed 11 dimensions that exist in the universe? I strongly believe there are multiple universes, each are isolated systems, who answer to completely different laws of fizyx. I also believe that black holes would be the portals to those other universes. rOZZ Music Pictures |

(think of it like a bubble in a detergent water) 2. we are more certain that our Universe is leaned on to other Universe with different set of rules...which our Universe might engulf & eat... (like a bubble to a bubble) so there must be sthg out there! ;) non-profit org. Play4Life in Zagreb, Croatia, EU |

In "Nature Physics" of 29 December there is an article about a meeting held on 7-9 December at Ludwig-Maximilians University in Munchen, Germany, in which the debating point was whether theories such as strings theory and multiuniverse with no experimental support can be considered as science or instead philosophy. A physicist I know by his writings and speeches on Italian and Swiss radios, Carlo Rovelli who works at Nice, maintained that while strings theory might find some experimental evidence (none so far at LHC even at higher energy), the multiuniverse theory cannot have any experimental support and must be taken as mere philosophy. I tend to agree with him. Tullio |

Agreed. We have no empirical proof whatsoever. The same counts for other theories like dark energy or even dark matter, neutrinos, gravitons and so on.. It is with great joy though I noticed scientists are trying to prove our collective consciousness through quantum physics. (quantum entanglement through teleportation) rOZZ Music Pictures |

Neutrinos are seen in detectors. Gravitons have not yet been observed, but the CMS experiment at LHC was looking for them and found a bump at 750 GeV which may be, or may be not, evidence of a possible graviton. LHC will restart in April. Tullio |

In 1995 I had sent prof. Roger Penrose at Oxford University an unpublished text of mine, titled "The coherent brain", written in 1980 and never updated. He replied with a letter, which I have conserved, saying that my text was "highly interesting" and advicing me to read his recent book, 'Shadows of the mind". Encouraged by this, I typed my text into a file and sent it to two Italian physicists, who knew me personally. None of them ever bothered to reply, even by saying "you are mad". So I ceased any effort to spread my ideas. Tullio |

There is no 3rd dimension in a 2-dimensional world just as there is no 4th dimension in a 3 dimensional world. Perhaps I should say that our universe expands from nothing in to nothing:) Comparing different dimensional worlds is always a problem and giving paradoxes. Consider this. The function 1/x from x=1 to eternity (Galileo horn). Rotate it and calculate what volume and surface it has. Yes, you will get a finite volume but an infinite surface. That means that you can fill the horn with paint but you cannot paint it! |

julie, If such a field exists then it should be detectable--not just imagined. |

Hawking is a "visible scientist" and probably has a lot of people writing to him. Penrose, although his equal in scientific value, is not a "visible scirntist" and can afford to reply to a letter by an unknonw person. But I must say that my text was read also by Roberto Battiston, now head of the Italian Space Agency, and he liked it too. Now he has no longer time. Tullio |

jan, Yes you are right about infinite surface but finite volume; As I have said before --at the very small our mathematics may be inadequate as evidenced by perceived quantum weirdness To wit:, The function 1/x from x=1 to eternity (Galileo horn). As you approach infinity you are in danger of dividing by zero which throws off our mathematics. If you allow division by zero to produce real world results then i can prove to you that 2 is equal to 1 Which I can assure you is not true in reality. |

Maybe he thinks too much of himself to provide you with an answer Tullio. rOZZ Music Pictures |

No, Roberto has mailed his answer to me. But he no longer writes on his blog on "Le Scienze" online magazine. I used to have interesting discussions with him, also on entanglement. Now he has to manage rocket launches such as the one which put Lisa Pathfinder on its route to the L1 Lagrange point on its search for gravitational waves. Tullio |

That also means that a Black Hole cannot exist in a singularity. Newton's law of gravity says in that case the gravitational force would be infinite. |

That's very philanthropic of him :) rOZZ Music Pictures |

What would we have been without the imagination of some great minds in our era? We would be nowhere without verification of well worked-out theories. |

I think we can blame Heisenberg for his finding that there is no thing as certainty in our universe. |
