  1. Hello all. I have noticed a surprising behaviour of time in the Forum. I mean time as it s mentionned near each post, & as it is mentionned at the bottom of each page. Here times are GMT-7. when I open some other page, it is GMT+2, which I prefer. It is quite disturbing. What is happening? Merged post follows: Consecutive posts mergedSorry, I had to write it down to figure it. When I log-in, time commutes to time of my PC. Now you know my time zone. Sorry for disturbing. But it remains a strange behaviour. Michel.
  2. Martin, this post of yours is wonderful. Your effort of explaining so many concepts in so few words is higlhy appreciable. It makes clear to anyone (I hope) how difficult are those concepts to explain, and to grasp. Talking about distances, for example, IMO there are 2 concepts-in-one. The first is distance in space, as we learn at school. Increasing distance is called motion, and increase of motion is called acceleration. O.K. The second concept is "distance-out-of-space", a concept nobody learn at school. When geometry of space change, distance (the second concept) increases (or decreases) without motion. You must know that no layman can understand a thing of it. Please, use another word for the second concept, and maybe someone may grasp something of it. I have the very strong feeling that even very renowned scientists use the one concept for the other without taking any attention of it.
  3. IMO if the current model admits exception, it is a very bad model that need improvement. And if your theory needs no exception, good for you. I think you should make a bigger case of this point. In my understanding, talking about hypotheses in general, only and only one exception should be enough to ruin an entire theory.
  4. All are at rest. Figure yourself in the workshop of Galileo Galilei 500 years ago. You are not alone. Galileo is there, Isaac is there too, and Albert. You are discussing the spheres of different masses Galileo has prepared for his experiment on an inclined plane. You are discussing the spheres at rest, before they go into motion. The last diagram I presented has five dimensions. Time is the one, Space has 3 dimensions (reduced to one on the diagram). That makes four. The 5th dimension is given by Mass. (is Mass a dimension, I don't know, maybe it is completely wrong and abusive, be careful with what I say). Here below the diagram again (bis repetita placent): It is dedicated to Mooyepoo who wanted to know where MT came from (see thread http://www.scienceforums.net/forum/showthread.php?t=46963)
  5. Are you saying that displacement is not null? If I had presented only the second diagram (the plane one), you surely had assured that displacement is null, as it is assumed in any physics book. Hm, yes. But is the word "earlier" defined in a physical way? For me the words "earlier" & "later" are words of the common language. Those words that do not help in understanding what is physically happening. When I say "earlier", it is like time (what is that?) were "flowing" upon my existence. When I say "traveling in time", it is like I (I suppose I know what it is) was traveling not is space anymore, but in time; a situation more familiar that makes you confident in expressing the assumation that displacement is not null anymore.
  6. Exactly what I was thinking about. Usually, the answer is inside the question.
  7. exhilarating Merged post follows: Consecutive posts merged Wrong. It is a crap. Gravity is due to mass, not to time. Michel is linking Gravity to Time in a misleading way. Time is one thing, Gravity another. The one is duration, the other is a force. Michel is a step away of saying that Time & Gravity are the one and same thing. I hope he will not dare making such an absurd assumption. The Einstein's equivalence principle is not enough to equalize acceleration in space with "traveling in time". Gravity is defenitely an attractive force due to mass. Traveling. No, at rest. Traveling into time. Okay. There is a fundamental difference between Time and Gravity. Time is a one-way concept. Time flows in only one direction, unlike Gravity which is both attractive & repulsive. Hum, not really. Only attractive actually. Anyway. If Time was the same thing with Gravity we would encounter paradoxal situations, in which for example an object that has no mass would experience no time. And that is completely contrary to observation. except for photons, of course. Hm. Well, how could he talk in the first place and introduce the concept of force in a diagram that has only Time & Space? Where is mass in this diagram? (words from the right side of my brain) Let's introduce mass. Here we are:
  8. There MUST be some mistake somewhere, as Swanson said. I figure it is not in the mathematics, it is in the logic. I am not really sure of what is going on, I didn't go into all your calculations, but it seems weird to me to obtain a triangle & straight lines after having "mapped all coords from the moving frame into the stationary frame" I can't help further.
  9. That means Equifax is still running in the background. You can check by typing Alt-Ctrl-Delete and check in the list of applications if the program is running. If it is in the list, you will have to remove the program completely (add & remove programs) or exclude the program from the sartup list.
  10. Look there. And also when you pose :"By the Pythagorean theorem," in your pdf. That is maybe the contradiction with t'=t. With the Pythagorean theorem you use Newtonian mechanics. IMO.
  11. Is that relevant? http://www.spaceinfo.com.au/ionosphere20090112.html
  12. Thank you for the link. The little video is very impressive http://cosmicweb.uchicago.edu/images/mov/bnr_half4.mpg ....and completely counter intuitive (except for the Chef-Coq mentionned above, who would see it as a missed receipe for vinaigrette) Like the expansion of a gas backwards. Organization from chaos. Negative entropy?
  13. Right. But you are a victim of vocabulary too. "displacement on the time axis"???? Displacement is null. Meaning "displacement in space", which the regular meaning of the word "displacement" How to call "displacement in time"? 500 years of physics since Galileo, and no word for it?
  14. Very interesting debate (except the civilities), please don't stop. I feel miserable because I belong to anothe time zone & cannot interact immediately because...sleeping. A. Martin, what is cob-webby ? B. I have the feeling neither you, me, the others, know what we are talking about. It should be preferable IMO to make some clear definitions-statements about the basic instances discussed. Space: what is that? 1.Some propose it as "Pure Emptyness". Is "Pure Emptyness" have been observed anywhere? Is "P.E." something gigantic, or something very very small, as the "space" between elementary particles. Is P.E. the same thing some scientists call "the void" (ses below)? 2. Some propose it as the "receptacle of everything", which is a definition IMO that is coming from some kitchen rather than a laboratory, because in this case "space" looks like a casserole.BTW such expressions are used for Time as well. From the same Chef Coq is presume. 3. Some propose the "fabric of space", as if space itself was made from something. it is the point of String Theory if I am not abused:the Void. And the word 'fabric of space" is often used in trying to explain deformation of space due to gravitation in Einstein's Theories. I believe these are misleading expressions used by scientists trying to explain mathematical deformations of field lines. Lies For Children IMO. 4. Some propose space as the Universe itself. As if Matter Radiation & Space were one and the same thing, splitted in 3 different concepts. i really don't have a strong feeling about it, still wondering. 5. Some propose space as part of a Space-Time continuum (the Standard Model), where space & time are 2 entities made of the same "stuff" (?) and having interchanging capabilities. In this case, a discussion about "infinity of space" alone, without time, is completely out of sense. 6. maybe you can put a 6th or 7th definition, I ran out of ideas. So, what are you talking about?
  15. Right. Bernard is subjected to earth's gravitation. But Aaron feels gravity from its own body, even if he was in empty space. under no external gravitational field, his whisky will turn into a sphere. How is that possible? And why don't you shoot me for having said such a monstruosity? Merged post follows: Consecutive posts mergedI hope I let enough time to interact. The assumption "Amelia is feeling a force due to accelerated motion, we call Gravity" is terribly wrong. I wonder how it could pass through without being shutted down. Because it was posed from the first beginning that Alfonso was standing at rest. The motion we are talking about is not motion, it is "motion through time". We have been the victims of vocabulary. I should have stated that "Andre is feeling a force due to translation in time, we call Gravity, and this force is the same with the force due to accelerated motion". In order to make things more clear, you can discard the second part of the sentence and put simply that: _Anyone is feeling a force due to translation in Time, we call Gravity. Michel.
  16. Right. Right. The only insight it provides concerns the fact that when you teach pupils that displacement is null, the intuitive reaction is to say "how is that possible, you just told me the object moved, so something must have happened". That "something" that happened is the translation through time. Even standing at rest, point A went to point A''''. And the object that travelled through points ABCD in reality has been translated automatically in time too. Here, again, there is lack of vocabulary. Translation in time is not motion, although my diagram may be confusing. Because I could not find any word for expressing "motion in time", I used to speak about "totion". Maybe it should be better to use "chronotion", but both look quite peculiar. So i'll stay at "translation in time".(I do not use "flowing" because it has inherent signification related to motion). Let's say now that B' is a star. The ray of light emitted from this star to point A (the observator) is represented by the red path, because light travels (the word "travel" includes both space & time, because nothing can travel a distance with zero time).
  17. here is a simple diagram, one could use to explain the difference between distance and displacement. Four points ABCD forming a square. And something moving along the path AB, BC, CD, DA. After the round, distance of travel is the sum of distances, displacement is null. Elementary. But because we are talking about motion, or displacement, and because we know that we need time to travel, let's introduce Time. We are obtaining something like this: That may look a little bit more complicated, but it is only a developpement of the previous diagram. Now we see clearly the difference between distance & displacement. Is that clear to you? Really, where is the distance? is that the sum of AB, BC, CD, DA, or the sum of AB', B'C'', C''D''',D'''A'''' (the red path)?
  18. We could split the question (returning to first question of this thread). Are we animals? I think the answer is yes. What makes us different from other animals? I am afraid nothing. that is not a bad thing, if you look at it twice. That makes us closer to nature. I suppose that the fact tha we are animals was not well received by ancient people (neither by modern people), so they invented culture, language, religion, civilization. Even today, return to nature is equal to seperation from civilization. Ah, something else. Language does not serve only for communication. The main purpose of language is identification of people inside a community. In many cases, language is a barrier to communication. There are plenty of examples. You may find inside communities barriers made from special language. The one who don't know the language will remain out. (as in this forum for example). on the other hand, import a russian dog in L.A., and he will communicate without problem with his new friends.
  19. We are in speculations, aren't we? Well I figure it is a little spark in our brain. Basically we are beasts. Independetly of our technology level, we are still acting as beasts. As countries & as individuals, in a less measure I hope. As for this little spark in our brain, if it vanishes, Humanity bye-bye.
  20. pykawit wrote I disagree. I think that "infinite possibilities" is not coherent with the laws of physics. We have been showed by Mother Nature that things have to obey (??how is that possible???) laws. I would prefer to define the Universe as the sum of non-contradictory possibilities. But we are missing the point. "Space" is different from "the Universe". Or isn't it?

  22. So, Ashley is sitting at rest on her chair, feeling no force. Everyone agree. Alek, Alfred, Anastasia, All agree. Except little Albert who says:"Well, actually, my friend Isaac is feeling a force". An apple just bumped upon his head.(Isaac's head, not Albert's) Silence in the classroom. Nonsense says the professor, there are in fact 4 forces anyone is subject to, just standing still upon his chair. These are the 4 interactions, which are 1 the Electromagnetic, 2 the Weak force, 3 the Strong force, and 4 Gravity. The force Isaac felt upon his head is Gravity and is an interaction of little particles called gravitons, it has nothing to do with motion. Little Albert raise his hand. "Actually, gravity is quite the same with the force due to accelerated motion, he says." Silence in the classroom. Nonsense says the professor. Amelia is feeling a force due to accelerated motion, we call Gravity. She sits at rest on her chair, doing nothing, sliding gently into Time.
