I'd like an education nefardec!

Could you recommend anyone that doesn't babble incomprehensible bullshit in response to basic questions? Someone that doesn�t spend their whole day masturbating about nonsense concepts that only exist in their own fanciful imagination? Someone that could respond to honest questions with equally-honest answers, taking into account the person who asked the question and their possible lack of specialist knowledge or terminology?

Yeah, I don�t spose you know anyone like that, huh?

since when is time travel a basic question? LOL

you're a dunce who spends his whole day masturbating about telling people they are masturbating about nonsense concepts

my statement regarding the assumption that 'time' is a human construct was rather simple i thought.

do you realize i could really care less what you think of me? and that probably most people in the world could also care less what you think of me? stop wasting (y)our time. this is why you are a dunce.


your statement was overly simple and not even worthy of the title of 'psuedo intellectual'.

The physicist's concept of time is a measurement of physical change. That doesn't necessarily have a lot to do with time as we experience it subjectively, which likely has more to do with the properties of the brain than anything else.

The human definition of time is a construct based on experiences that we have on earth.

Time would be viewed differently by any other intelligent race in the universe.

I suspect that any intelligent species would develop a technique for using regular physical processes, like the "rising" and "setting" of the sun, or the phases of a moon, to keep track of and plan less regular stuff. Once you do that you have a basic physical concept of "time."

I see what you mean. The formal analysis of this kind of stuff is the subject of a branch of math called measure theory. Intuitively the outcomes can't all have the same probability, because their sum wouldn't be 1. So there would have to be more probable and less probable universes, which seems to make sense. So the stuff I posted about a bell curve was kind of irrelevant because it's a continuous rather than discrete distribution.

But here's a question -- if there are many universes, why should there be only a discrete set of universes (countably many, such as {1,2,3,...}) as opposed to a continuous spectrum of them (uncountably many)? Just take the current universe and all of the physical things it contains -- you could continuously vary some or all of their physical properties (or can you? does quantum stuff forbid continuous variation?) to make uncountably many new universes. In that case, the probability of any particular one of those is indeed 0.

No.
I can't believe that philosophical crap is that widespread.

Why does nefardec get so much hate???

I value his posts and believe that he represents an 'educated' perspective on various topics - I didn't say insightful or 'right', and so far as I know, he has never claimed as such. But he always brings something supportable to the table, though it's strongly skewed towards academic theory.


Posted by pkcRAISTLIN on May-28-2009 15:32:

because he's a hippy.


Posted by Halcyon+On+On on May-28-2009 15:33:

Oh. Well I'm not gonna argue with that.

Whoa there big fella.... I'm not sure either of us (you and I) understand what you're actually trying to say. Time is a measure of distance... if you accept that the universe has topology then you must also accept that there is distance between points within the universe, which means that time is a real thing, not a perception.

Edit... for clarity, I mean time is a real thing in a physical universe... I suppose that if there was no physical existence then there would also be no time.


Posted by Halcyon+On+On on May-28-2009 16:29:

I have always considered time a measurement like any other - length, width, weight - they all have their (mostly arbitrary) units for measurement, and our units for time are no different as even a single second is standardized to the vibration of a cesium atom.

It seems to me that distance has its own units (point A to B) and that would be miles, inches, kilometers, meters, etc. Time seems more a measurement of movement than of distance, though it also seems to encompass entirely "still" (assuming such a thing is possible) entities or objects. But if our universe - our dimension, maybe - is indeed "curved" by our sensibilities, then time is merely a linear measurement of relevance to the existence of a perceptual phenomenon - not to imply that time is entirely linear or anything, but it sure makes it easier to consider it as such.

But perhaps time is indeed a measure of distance (as you said, Moral, assuming the universe is a susceptible to topographical considerations), it just isn't the 'linear' distance we are normally acquainted with.

Hey, wait a second...


Posted by Meat187 on May-28-2009 16:36:

Also, I don't really buy into the infinite worlds stuff. Wasn't that just created to solve a time travel paradoxon that indeed wasn't even a paradoxon at all?

I think this posting informs this discussion fairly significantly:

Traveling to another time changes time in and of itself because the changes you cause in one particular timeline changes the entire timeline. You never know.

What the fuck?


Posted by Halcyon+On+On on May-28-2009 17:23:

Succint, yet accurate.

If you travel back in time, you are traveling to what is basically a parallel universe at a different point on the timeline than when you left the present. You would likely never return to the universe you left because of the mere fact that the present you existing in a previous time would change the future, and thus change the universe you are likely to return to. You probably won't even be born, and so, on your return, no one would know you, and you'd be lost forever searching for your home universe.


Posted by Halcyon+On+On on May-28-2009 18:15:

Well then you've been travelling in time wrong. That's never happened to me.


Posted by yukii on May-28-2009 18:16:

me either, i did it last week with my cat. we came home safe & sound.

Stop watching Sliders and get a clue.

I know I know, it's hard to grasp, but it is true!! Give it shot. I bet you'll never come back.
