Time may have a geometryAlexander Mayer of Stanford University is proposing that we re-think how time behaves at a local level. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..." - Leon M. Lederman #2 2006-02-06 09:49:39
Re: Time may have a geometryThat kinda stuff creeps me out. No thanks! lol. A logarithm is just a misspelled algorithm. #3 2006-02-06 13:36:45
Re: Time may have a geometryI believe the universe is a 256-dimensional space/time hyper-space that vaguely resembles the structure of a 256-dimensional hyperbola rotated around a 256-dimensional hypersphere perpendicular to the axis of the hyperbola. A warping of the space time continuum actually just shifts the foci in the 32nd, 64th, 96th, 128th, 160th, and 192nd dimensions. #4 2006-02-06 14:48:29
Re: Time may have a geometryI am exteremly skeptical, especially when it comes to:
But I'll have to read all the pdfs/powerpoints in great detail before I can comment further. It might take some time. "In the real world, this would be a problem.

Re: Time may have a geometryThere is a law that says it is impossible to accurately observe anything you are not independent of. For all you know, we could just be part of a huge matrix of data that is constantly being changed by means of various complex functions. We cannot observe our own universe accurately past a certain point. #7 2006-02-07 04:41:50
Re: Time may have a geometryThere is a theory which states that if ever anybody discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another theory which states that this has already happened.
It is impossible to observe anything without interacting with it, period. For example, you can only observe your computer screen because electrons are hitting phosphorus (possibly another chemical) creating photons, which hit your eyes, change protiens in your eyes, which send an electrical impluse to your brain where even more freaky stuff happens.

Re: Time may have a geometryI, bleary-eyed and spent, have managed to sift through all 90 slides there. Opinion? At this point interested, but will have to wait for the people with the data and experience to pick it apart thoroughly before getting too excited. With my limited knowledge in this area, everything stated seemed at least rational. So I reserve judgement. #9 2006-02-07 11:00:50
Re: Time may have a geometryIt is an interesting theory, but just a theory of course. Time will tell (excuse the pun) "The physicists defer only to mathematicians, and the mathematicians defer only to God ..." - Leon M. Lederman #10 2006-02-07 15:09:28
Re: Time may have a geometry
Can you give some examples?
But we have even found dark matter! All three types of neutrinos are dark matter. A team of scientists (international effort) in France are building the largest particle collider which is theoretically supposed to be able to detect gravitons, another type of particle which has yet to be detected.
A better question is why are these ideas going into a book and not a peer-reviewed journal? Last edited by Ricky (2006-02-07 15:19:42) "In the real world, this would be a problem.

Re: Time may have a geometryHey Ricky, aren't neutrinos mostly massless (as in, massless as photons, or more)? El que pega primero pega dos veces. #15 2006-02-07 16:46:14
Re: Time may have a geometry
Historically, it is those who wish to advance science that publish it in journals, and those who wish to make money that publish it in books. It is also those who publish it in books who are normally wrong. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #16 2006-02-07 16:58:53
Re: Time may have a geometry
You are correct about neutrinos. They have such a small mass that they were able to go undetected (but theoretically proposed) for 30 years. But they do have mass.
Again, you are correct. Gravitational models of the universe did not correctly explain what we are seeing. So dark matter was suggested as a solution to this problem.
Again, right. But the one thing you seemed to have missed is that there is an extremely vast amount of neutrinos coming out of a single nuclear power plant, let alone the sun, let alone all of the stars in the universe. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #17 2006-02-08 10:54:34
Re: Time may have a geometryLet me start out by saying that I try to correct people when I think they are wrong (notice the emphasis on the word think). I do it in math here on this forums, but it doesn't just stop there. I do it all the time, no matter the subject. That's all I'm doing when I reply to your posts.
I understand this was a joke. But there is an underlying implication that I think you missed or aren't aware of. All science works this way. It's known as falsificationism. Theories are suggested, put to the test, and are either not falsified (kept) or falsified (thrown away). Now it's a heck of a lot more complicated than that, but that's the very basics of it. But to keep it simple, that which has yet to be falsified is known as "correct" in the scientific context.
I don't think you know how the Big Bang Theory came about. It was first observed that spiral nebula were moving away from us. The Big Bang (although not in its current form) was proposed. Then it was observed that not only are (almost) all stars moving away from us, they are doing so at a proportional speed to their distance from us. Such evidence is only explained by the Big Bang. Then we observed cosmic background radiation. Such evidence is only explained by the Big Bang. Furthermore, it is once again only the Big Bang which explains the abundance of lighter elements in our universe.
The first part is correct. The Big Bang makes no predictions as to how the universe started. All we know is that "something" happened. But we know the entire history of the universe very shortly after this something. And we do know it happened. We understand the Big Bang more than we understand the Theory of Gravity.
You may say it's ridiculous, but it turned out to be right, didn't it? "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #18 2006-02-08 11:49:35
Re: Time may have a geometry
I took that theory how I thought you intended, as a complete joke. But the quotes above, joke or not, are flat out wrong. Not observable, not testable, not falsifiable, and doesn't explain a single thing that the Big Bang does, come to mind.
What about theories like Relativity? Or the Theory of Evolution? These are treated almost universally like facts in the scientific community. Which is the same way the Big Bang is treated.

Re: Time may have a geometry
Imagination has nothing to do with it. And besides, I don't have to imagine anything. Technically speaking, a neutron star is a huge atom about the size of chicago.
