An Event Horizon is simply a posh term for a point of no return. When I asked you that question is why I read and on the Internet there are theories about a black hole that could be '' the entrance '' and the white hole '' the exit''. A kind of gallery or bridge between two universes. The matter and the light that is swallowed up by the black hole may be "sputtered" in another universe. Obviously is a theory. Hawking has also suggested that what goes on in the black hole may not be lost and that it might come out somewhere else. So I read. |

I don't know about wormholes. But since the void is not void at all and can produce a couple particle-antiparticle in a fluctuation for a very short interval of time, if one of the two particles is absorbed by the black hole the remaining particle cannot recombine and gives what is know as Hawking radiation.

Forget about such a thing as time when it comes to both gravity and also massive objects which could be part of space. In my opinion it really does not matter at all. I already mentioned it and what is next the explanation? The word "arbitrary" comes to me by watching a YouTube video and at least gives a hint of possible ideas which could be around. Except for the precise word for this, of course. But here the possible difficulty as well, because I do not wish to make it any "Mysteries, magic and miracles" either. Trying hard here and next it reads, "A defining feature of special relativity is the replacement of the . . ." . Oh, I interpret that above as that of possible multiverses possibly existing. This because of the sentence "Time and space cannot be defined separately from each other". And more importantly, the following sentence, "Rather space and time are interwoven into a single continuum known as spacetime" (partly hyperlinked). Next "Events that occur at the same time for one observer can occur at different times for another". You really do not need an elementary particle like the graviton for such, rather a given notion for the similar, but still hard to explain. For now, watching the videos. |

Yes, which probability, except for perhaps not any Probability at all? Except for that, Bump, or perhaps Bingo! as usual, because I looked up the account of Gordon for only what he have to say here and ended up with Message 1900676 here, by Chris S. https://setiathome.berkeley.edu/forum_thread.php?id=82130&postid=1900676 In fact no so, because if you mix in such a thing as a notion of time, you next could be doing so for that of possible extraterrestrial intelligence. First perhaps no so, but is not really this the point of it all? While time is perhaps relative as a notion, traveling through space is not necessarily the same as travel through time, although the latter could be possible. We are supposed to believe that time could be stopping up, or ceasing to exist, not only because of time itself, but rather because of gravity. If not previously mentioned, time should always be made with reference to itself and not necessary that of gravity. There could be some confusion around and I do not have it either, but space and time should be interlinked, but next also that of time with a reference to itself. |

We could easily explain our concept of time to an ET by saying we measure elapse between two events by recording long it takes for our planet to rotate once on its axis, we call that a day. We divide that elapse into 24 portions called hours, again by 60 for minutes, and again by 60 for seconds. It takes our planet 365 1/4 of these days to orbit our star, which we call a year, divided by 52 which we call weeks, that have 7 of these days. Well your explanation of what time is very strange to me and certainly to aliens visiting our earth. You make the assumption that planetary objects are include in the calculations of time. Makes no sense to me that aliens do that kind of calculations. Why should they? |

I think you need to read up on black holes Andrew!! What! "The gravity is so strong because matter has been squeezed into a tiny space" But that is wrong and a misconception! There is no matter any longer when matter fall into a black hole. The nature of a black hole is very well understood and explained by Kip Thorne (He will get his Nobel Prize about Gravitational Waves next month), Stephen Hawking, Max Tegmark, Leonard Susskind and many other scientists. As for white holes. They are very hypothecial. Perhaps the Big Bang was one. Who knows? |

And Sweden also believes in the bible. What? Sweden is among the most secularised country in the world! Trust me. I know a lot about Sweden. You don't! Many religous Swedes moved however to the US in the 1800th hundreds. In fact a third of the Swedish population did that at the time! http://www.history.com/news/americas-forgotten-swedish-colony https://www.youtube.com/watch?v=RlNhD0oS5pk Ah-ah, ah! |

Hey Chris, it has been determined that many exo planets are tidally locked to their star resulting on one side being in eternal light while the other is always night. So, if such a planet is home to intelligent life they probably don't have a concept of a day. Bob DeWoody My motto: Never do today what you can put off until tomorrow as it may not be required.

This mystery doesn't cause me to lose sleep at night but it does cause me to question many of the claims of facts about the universe that are made these days.

But also that a couple of lights visible in the sky is not synonymous with any life either, because we have yet to detect an intelligent signal coming from space. It became a search for a missing woman in my country, and they were using headlights on top of their heads, and next out into the snow for that. But except for a total of seven men in the picture, one just behind another, also a yellow light visible at the left as well, of the same size or luminosity, but also a more blurred speck at the right as well, and next into the air for perhaps both, and also not a reflection from the headlights themselves either. But still that we could make it hard science for a couple of things, except for not using neither eyes and ears for that of your senses for some other things. In the end, perhaps not that of Religion as a subject, but rather that it should depend on the subject itself, next in question. |

According to new measurements made with the Hubble Space Telescope the value of the Hubble constant is not 67 km per second per megaparsec, as measured by the Planck satellite of ESA, but 73 km per second per megaparsec (3.3 million light years). This means that the Universe is expanding faster than it was thought so far. Tullio |

Wiggo, I happened to listen in at Michio Kaku yesterday, I think. Here that of Type I, Type II and Type III civilizations, possibly with respect to each other. But next that when Dr. Kaku is making it a Type III for this, he possibly slips on that of wording, and it becomes that of harnessing a single star, much like a Type II civilization. Same goes for both Religion and also Theology as well, in that we still could make it a couple of planets in our solar system, while also the magnificent splendor of the whole Universe. I tried to make it a bit of Creation here, if not also giving a thought about a possible Creator being responsible for everything, but for this you perhaps need to look at Creation myth, rather than that above, in that both Matter and also Equations, become the application for that meant for possible use, while also that of a Creator becomes its own meaning for that of its understanding. And next it should not be "application" above either. It should be easy to make it the fact that humans could still be a product of both evolution, and also nature. If nature should also be about the Universe, we need to understand it not only for its intended purpose, but also its possible meaning. We could still be having a sometimes basic debate of whether any regular people, or even scientists, could be making up one thing for that of another. Creation is supposed to be everything, including those things we could see around us, and for now it also became the Aura as well, for possibly one secret behind. If perhaps still a couple of simple tricks, for that of the mirror, for example, most likely Religion is not supposed to add any much new to the debate. We still could make it a couple of things not in its correct place, like possibly the Hammer and the Feather, if not any photons for that of visible light, when it rather could be something else. Similarly, the famous equation by Einstein, could be yet another way of understanding how things are supposed to be working, except for not any philosophical questions either. If perhaps still about Physics, it could be shown that the Universe is mostly about Matter, by means of mass, Energy, and also gravity, and for each we also could have their respective Equations. Make it rather that of both life and also Intelligence, also that Probability could be telling about a given chance for that of life, in that it could be striking luck at times. Still perhaps a difference between the surface of Mercury, and the gaseous atmosphere of the outer planets, but there could also be suspicion around, that someone made it into space before us, and next that they came from other stars of the Milky Way. If other intelligences should be around, they could be using nature itself as a possible tool for that of what they could be doing, like that of possible space or time travel. We know that possible smoothness for that of manned or unmanned flight, could still end in catastrophic failure, only because nature is so. If perhaps still a bit of bad wording, also that 1+2=still 3 for that of an Equation, and next that it also cold be the Three Laws of Newton for this. Except for that, have a bit of time off for that of relaxing, and next also perhaps dreaming a little, and next wish you could be somewhere else. Still in both flesh and blood for that of ourselves, and also that of still some 0.84 on the Kardashev scale, if not making it anything else which could be telling about a Universe which could be slightly different than ourselves. |

Any new physics theory will certainly include the word "dark". At Gran Sasso underground Laboratory they have recently started a new detector of WIMPs called DarkSide, which uses liquid argon Tullio |
