Does Time Actually Exist?

[marcel_leonard]

When we discuss Time we are actually discussing a derivative of Distance; as in the case of a Space/Time continuum. It takes approximately 8 seconds for the light of our sun to reach your retina, and when we speak of Light Years what we are really measuring is how many years it takes for a distant star’s light to reach the Earth. In all actuality when we look up at the nights sky what we are really looking at are millions of years in the past. <br /><br />When we look at the nearest star to us Alpha Centuri which is 42x10^6 Light Years away; what we are actually watching is what happened 42 years ago. Keeping that in mind since it takes incredible amounts of time for light to travel from our nearest star; imagine how far back in time we are looking when we observe the Andromeda galaxy? My point being that time is relative and depend on your life span it can become meaningless. <br /> <div class="Discussion_UserSignature"> "A mind is a terrible thing to waste..." </div>

4.2 years ago! Alpha Centuri is only a little over 4 LYs away from the Solar System.

a simple slip... maybe. <div class="Discussion_UserSignature"> <p>pain is inevitable</p><p>suffering is optional </p> </div>

If time were a fourth dimensional measurement of the known universe then we couldn’t possibly comprehend the complexity of measuring time as three dimensional creatures. Imagine a two dimensional ameba living on a microscope slide which was capable of moving to the left or right; and back or forth, but could never possibly comprehend up or down because it was not three dimensional… <div class="Discussion_UserSignature"> "A mind is a terrible thing to waste..." </div>

time as a dimension only refers to the <font color="yellow">date</font>and nothing else. <br /><br />like this:<br /><br />I am now in the Boracay beach<-----3dimensional<br />I am now in the boracay beach, 5:00AM in the morning<----with time as a dimension/referrence point<br /><br />we must remember: <br />each step you make on the plane ( as in coordinate plane/geometrical plane ) ground may not be done again. on earthly level, yes. You can step on the same ground twice/hundred times etc. But, on a universal level--- /> no. the plane your foot had intersected will not be the same plane in this vast space in the second time you step your foot. so time is used as a referrence to give sense on where and when things/information had existed. <div class="Discussion_UserSignature"> <p>pain is inevitable</p><p>suffering is optional </p> </div>

If time were some easy function of distance then we would have found away to not only travel back in time mathematically, but practically as well… <div class="Discussion_UserSignature"> "A mind is a terrible thing to waste..." </div>

[harmonicaman]

I dunno...<br /><br />Gravity seems to be the manifestation of "m" (mass) interacting wth time ("c"). I don't know if mass is actually emitting or absorbing time; but gravity results wherever time and mass are in close proximity...

For me - Time is the non-event between events. Tick and tock just represent markers for nothing at all. Remove the markers and there will be no time like the present.

 

[marcel_leonard]

Time like any other dimension can be measured, but that is where the similarities stop. Given the linear nature of the way we experience time it would seem to me that we can only hope to understand time not as mere mortals but as immortals… <div class="Discussion_UserSignature"> "A mind is a terrible thing to waste..." </div>

 

[neutron_star69]

time=immortal<br /><br />can you kill time?<br /><br />does time last forever?

 

[bender007]

well when your 17 you ar not half way through your life remember peoples perception of time is diffrent but time is always constant and never changing

<i>For me - Time is the non-event between events. Tick and tock just represent markers for nothing at all. Remove the markers and there will be no time like the present.</i><br /><br />I like it.<br /><br />Time does not exist as an entity unto itself. Time is an aspect of space, without which space could not exist. Just another dimension - not a flow, river, ocean or wave. Those watery images resonate with our psychological perception, our subjective impression of what time is.<br /><br />Just thinking out loud, that's all...

 

[eric2006]

Maybe time is flowing backwards into a singularity. But we experience the mirror image of it. So really birth is death and death is birth? <br /><br />We could be viewing the mirror image of gravity as well. Maybe it is really a push force.<br /><img src="/images/icons/crazy.gif" /><br />

 

[eric2006]

Here is a crude diagram of my idea. The present is like a little cart that wheels around the "wheel of time".<br /><br />Yeah it's crazy but so am I.<br /><br />This would only work in a universe that has a big crunch. History would repeat itself exactly the same way forever. <br /><br />The little cart (the present) is stationary. It is time that is moving. Counterclockwise in the model. Or backwards.

 

[eric2006]

Oh yes. I it does suck. <br /><br />Just bare with me. I came up with this whole theory like 5 minutes ago and I am trying to work out the flaws. <br /><br />Any critics or supporters here?<br /><br />Should I not quit my day job?

 

[serak_the_preparer]

<i>Maybe time is the sum of all histories reaching us from the visible universe.</i><br /><br />Maybe not all histories, but, yes, a good call, I think.<br /><br />We talk about processes and change in order to discuss time. Maybe we're really talking about something else? If the universe is really a multiverse, perhaps time is just our perception (or information, or knowledge) of the relationship between some of those histories? Those histories which contain us, that is.

Therefore, for every observer, light travels 299,792,458 meters per second. The electromagnetic energy coupled to a gravitational field slows down when the strength of the gravitational field increases. Therefore, the electrons and the photons they emitted have a smaller "ds" which means they travel at a slower rate relative to their center of mass.

[marcel_leonard]

Having understood the theory of relativity as a derivative of the speed of light; one can assume that “Time” is decreasing as you move closer to C=299,792,458 meters per second. What if “Time” as we know it was not a factor in our observations than the speed of light would only be relevant to distance, and “Distance” would virtually be instantaneous from point “A” to “B”.<br /><br />My point being we will never achieve an ability to travel at the speed of light, or even faster then FTL; until we amend our definition of “Time”.<br /> <div class="Discussion_UserSignature"> "A mind is a terrible thing to waste..." </div>

<i>"A mind is a terrible thing to waste!!!"</i><br /><br />Yes, and so is time.

marcel_leonard - Hi! [I'm the former paulharth6, btw]<br /><br />Time is certainly real - as in what would have happenned if we ... (kept going to the moon, etc.)<br /><br />My definition of time: the medium through which cause and effect flow.<br /><br />Such that causality cannot exist without time.<br /><br />However, our universe including our universe specific space-time was caused, or created.<br /><br />Therefore I postulate primordial time. <br /><br />My definition of primordial time: time outside our universe but in the vicinity of our universe during which our universe was created.<br /><br />Note that there may be many other universes which were or are being created during primordial time which would all have their own universe specific space-times.<br /><br />Note also that time outside our universe may flow faster or slower than time in our universe.<br /><br />A hint at variable concepts of time:<br /><br />(2 Peter 3:8) 8 However, let this one fact not be escaping YOUR notice, beloved ones, that one day is with Jehovah as a thousand years and a thousand years as one day.. . .<br /><br />Certainly this subject is interesting and takes some time (pondering) to comprehend.
