Radiuses are never equal to 0...they can't be! the thing is: we know Neutron stars are smashed in only neutrons...that is why we call them that! we can't think of another "scale" to which Black hole is smashed into...what is the next boundary? for the understanding of that, we would know that Black holes are just different type of stars...to we don't understand the physics right now & they are Black...so we call them Black holes! ;) something that goes almost to 0...and it is deviser...then the calculus equals to enormous number...one that is almost infinite, but not quite! check your limeses...something can tend to go to infinite, but never become infinite! ;) well, yes...this Space / Universum might be 687687521 version of the tryout...a one that succeed with just right proportion...with just Planck constant, that it exists... and there might be other Universes around us...with different Planck constants, or different Higgs energy field - that are more or less stable... ;) & one thing that puzzles me: Why scientist try to prove that the total energy of Big bang in the beginning was 0, when the math & physics says it isn't so? They loose the energy on proving that there isn't a Higher being...but it's their life to loose! ;) non-profit org. Play4Life in Zagreb, Croatia, EU |

one thing that puzzles me: Why scientist try to prove that the total energy of Big bang in the beginning was 0 Back to our universe:) Entropy was 0 in the beginning. Not Energy:) In fact Energy was given to us at time zero. A lot of Energy. After a while, 2 minutes perhaps, some of it was used to make particles. Yes All that there is in our universe is nothing but energy in some forms. Does it disappear in time? No. However entropy are rising all the times. In thermodynamics, entropy (usual symbol S) is a measure of the number of specific ways in which a thermodynamic system may be arranged, commonly understood as a measure of disorder. According to the second law of thermodynamics the entropy of an isolated system never decreases; such a system will, without further energy input required from an outside system, proceed, by releasing free energy, toward thermodynamic equilibrium, the configuration with maximum entropy. Systems that are not isolated may decrease in entropy, provided they increase the entropy of their environment by at least that same amount. Since entropy is a state function, the change in the entropy of a system is the same for any process that goes from a given initial state to a given final state, whether the process is reversible or irreversible. However, irreversible processes increase the combined entropy of the system and its environment. |

I saw these funny comments about it. This is pretty interesting; linking this to the Fermi Paradox thread, could an advanced civilization cloak a whole galaxy so that it would appear to be absent? |

btw Do you know long a Planck length is? Oh dear. You mean there are short and long meters as well? |

No, gas and electric meters are about the same size. Metres are 39.37" HeHeHe. I see. We have semantic problem here:) Why not use the word "gauge"? Meters and meters in English are homonyms... Not here. Mätare och meter. And we still use inches or thumbs as we call it. About 2.5 cm. A yard is about 1 meter. 4 of my feets is 1 meter. Mätarlarv. |

one thing that puzzles me: Why scientist try to prove that the total energy of Big bang in the beginning was 0 and here we throw the Thermodynamics through the window...most importantly their laws! Entropy is also a function of energy of a system...& it was nearly zero, but not zero! Never can it be, never will it be...or we wouldn't be here, if it were! ;) non-profit org.

So a Black hole mmmmmm A clocked Universe mmm The Q maybe ? I thought that area was thought to be where 2 Universes touched each other and was pointed to as proof that the Multiverse can be proved with this evidence ? I wonder , is that why the universe is moving in one direction ? It's being pulled into the Black hole ! Saved from the big pull to go out in a big crush after all ..... |

one thing that puzzles me: Why scientist try to prove that the total energy of Big bang in the beginning was 0 Maybe it's true that in our universe entropy have not been zero in any time. But in a multiverse that the entropy has not been zero means that a multiverse have existed forever. Thats possible, but we humans like to have a beginning. Now if there is a beginning that means something existed without anything not even energy. So what is the entropy in the beginning? Yes zero because there is nothing to disperse. |

Entropy is disorder. The Universe is running down--therefore more disorder and increasing entropy. Zero entropy means perfect order--Probably a correct way to think when everything was compacted. |

one thing that puzzles me: Why scientist try to prove that the total energy of Big bang in the beginning was 0 Problems with Big bang theory: http://science.howstuffworks.com/dictionary/astronomy-terms/big-bang-theory7.htm You can have a begining, without the zero...example: do you celebrate your birthdate or your conception? how come you celebrate your birthdate, even though you have been living for 8.5months? ;) there was something in the begining...a pan-soup (like pan-gea on Earth) from which a Higgs fields shifted to higher state & created the Universe...some of those pan-soup doesn't interfere with other particles or Higgs bozon or it's not trasfered with Higgs field into this Universe...those we call Dark matter & Dark energy (but that's my opinion only)... Entropy was almost zero...like limes, it tended to become 0...but never could! Like we say Universe is infinite...but it's open Universe that exands...and has it's walls which we can see by CBR...so we have concluded that the Universe in which we live in is about 28Gpc...very, very, very, very, VERY, VERY LARGE...but not as infinite as someone might think so?! ;) non-profit org.

Entropy was almost zero...like limes, it tended to become 0...but never could! Why not? Have you been there? :) Entropy doesn't tend to become 0. Entropy has only one direction, like time. Arrow of Time. As one goes "forward" in time, the second law of thermodynamics says, the entropy of an isolated system can increase, but not decrease. Hence, from one perspective, entropy measurement is a way of distinguishing the past from the future. http://en.wikipedia.org/wiki/Entropy_(arrow_of_time) The second law of thermodynamics applies to an isolated system. Are our universe an isolated system? Entropy also require space. According to the Big Bang Theory there was no space in our universe in the beginning. |

The omnipotence paradox from an islamitic point of view:) https://translate.google.se/translate?sl=sv&tl=en&js=y&prev=_t&hl=sv&ie=UTF-8&u=http%3A%2F%2Fislam.se%2Fgudssyn%2Fallsmaktighetsparadoxen&edit-text= Black hole. Is it not just space that's warped in the space-time fabric with no mass? Only gravity and information, a LOT of gravity.

If there is a big Black whole then should there not be that said black hole , still ! They have map'd the universe so why can't we see it in the Maps ? There should be some big whole somewhere in the maps . |

If there is a big Black whole then should there not be that said black hole , still ! You can't see black holes:) But you can see the Surface that is VERY hot and radiating a lot of photons. Another way is to study stars around the black hole and check there rotational speed. Has it been done? Of course. In Hawai they checked rotating stars in the middle of our galaxy. Thats a compelling evidence that we have a super massive black hole is there and probably all Galaxies have black holes in the center. |

Ok here is Mad Max (Max Tegmark) views on many things:) https://twitter.com/tegmark For instance Cosmic art: isn't the magnetic field traced by that loathed Galactic dust magnificent? http://www.nytimes.com/2015/01/31/us/a-speck-of-interstellar-dust-rebuts-a-big-bang-theory.html?_r=0 Raphael captured an important scientific principle: "question authority".

Mad Max,(Max Tegmark) , loves this # Oh dear:) Thats a big number! With today's computers, it would take about 1085 years to just write out all the zeros. The name Googol comes from a mathematician that had a small daughter who liked the Word. Dad is googol:) |

The BAFTA and RTS Award-winning BBC documentary PARALLEL WORLDS, PARALLEL LIVES follows the lead singer of US rock band EELS, MARK OLIVER EVERETT, on his journey of discovery across America to learn about the father he never knew, HUGH EVERETT III, the quantum physicist. Hugh wrote the theory as a young Ph.D. student at Princeton University, but for 20 years it remained largely ignored by the scientific community. Faced with derision and rejection Everett abandoned academia and forged a career in the American defense industry. It was only at the end of his life, that his visionary work began to be taken seriously. http://www.eelstheband.com/parallel_worlds.php Mad Max is also in the docu:) |

Astronomers discover largest known structure in the universe is ... a big hole I wonder what they think a structure is. We all know for certain that our universe is a structure. And that's huge. I for one believe that it must be more than our universe. Otherwise... Can math help us? Of course. It can be true that our universe is infinite. You can have a subset of infinite that is also infinite. How come? Do this. 1,2,3,4,5,6,7,8,9,10 to infinity Now odd numbers. 2,4,6,8,10 to infinity Both sets have the same size:) How can we know that? Quite simple really. Instead of using ordinals use cardinals instead. For instance first, second, third and so on to eternity:) |

There are several notions of infinity in the Mathematical world. Check out ALEPH-Null |
