Time

[bonzelite]

time is an illusion of human perception. <br /><br />as you say, there is no time. all interactions happen at the same instant. <br />

 

[rfoshaug]

What is an instant if there is no time? <div class="Discussion_UserSignature"> <p><font color="#ff9900">----------------------------------</font></p><p><font color="#ff9900">My minds have many opinions</font></p> </div>

The universe needs <i>time</i> to expand. Without <i>time</i> we'd still be stuck back at the Singularity. <br /><br />You cannot exceed the speed of time ("c") because the expanding universe hasn't gotton there yet; that's why it would take all the "E" in the universe to get your "m" up to "c" velocities. <br /><br />Exceeding "c" would mean exceeding the expansion of the whole universe and that would take a lot of energy!<br /><br /><big><b>E=mc²</b></big>

 

[neutron_star69]

how can there be no time? are you saying were are frozen?

 

[tex_1224]

Time is a Law. Like gravity. We cannot ignore it. Outside the Earth's gravity boundry, gravity becomes Zero. Thus, so would Time in the same Order, but in a different degree become Zero as we passed through it's boundry. Just as a rocket cannot shoot a straight line to break into outer space, so is Time to be broken through on a Curve. The space shuttle must rotate to get out of the Earths gravity hold. Look at the Moon. It's stuck. And so, as we move through Time on our linear paths we are stuck in an order of instants, one after another. The Law of Time.<br /><br />Take Earth. O.K. You have + North pole, and - South pole. And throughout the Earth are centers of + or - gravitational forces. These forces are what gives the Earth it's Sphere shape. Now, there is One point on Earth that is Both, positive and negative... The Core. The center of the sphere is both positive and negative. The construct of Time is a lot like that of the gravitational forces of a Planet. So, our number line, is very primitive. The Earth is not flat.

Anyone figure out the Time curve yet? How long until we break the speed of light barrier?

 

[qso1]

My guess, were nowhere near breaking the light barrier. We have to break the cost barrier first. BTW, we have only reached .01% SOL on average with unmanned probes. <div class="Discussion_UserSignature"> <p><strong>My borrowed quote for the time being:</strong></p><p><em>There are three kinds of people in life.

[jatslo]

The speed of light barrier will be broken within a quantum computer this decade; my bet. If not, then cause and effect will be indistinguishable, as a result.

 

[xmo1]

Anyone concerned that this might cause a quantum nuclear event?. <div class="Discussion_UserSignature"> <p>DenniSys.com</p> </div>

 

[jatslo]

Well, annihilation is always a problem; why, yes, that is a concern. Might make for a cheap energy source. <img src="/images/icons/wink.gif" />

 

[bonzelite]

well, allegedly,<i> very allegedly,</i> they've conducted teleportation of particles that arrive at a place before they've left, so to speak. how about that? <br /><br />and there is always the debate over gravity: it is not a force that propagates but is a geometric property of the expansion of matter, acting instantly upon free-floating bodies. so that certainly violates GR.

<font color="orange">well, allegedly, very allegedly, they've conducted teleportation of particles that arrive at a place before they've left, so to speak. how about that? </font><br /><br />I believe you are talking about Wang's experiment<br /><br /><font color="orange">and there is always the debate over gravity: it is not a force that propagates but is a geometric property of the expansion of matter, acting instantly upon free-floating bodies. so that certainly violates GR.</font><br /><br />Even if one does subscribe to this ad hoc hypothesis, it wouldn't violate GR as there is no interaction between the 2 objects. If gravity doesn't exist, how can it be FTL?<br /> <div class="Discussion_UserSignature"> <div> </div><br /><div><span style="color:#0000ff" class="Apple-style-span">"If something's hard to do, then it's not worth doing." - Homer Simpson</span></div> </div>

 

[spacytin]

is there beginning to time? if so when did time begin??

 

[vogon13]

In fact, prior to a BB, a 'universe' totally devoid of everything will not experience time, there being nothing with which to mark it's passage.<br /><br /> <div class="Discussion_UserSignature"> <p><font color="#ff0000"><strong>TPTB went to Dallas and all I got was Plucked !!</strong></font></p><p><font color="#339966"><strong>So many people, so few recipes !!</strong></font></p><p><font color="#0000ff"><strong>Let's clean up this stinkhole !!</strong></font> </p> </div>

 

[pyoko]

Perhaps during the 'time' of the Primordial (?sp) Nucleus directly before the Big Bang (I hate how many time words I have to use here), since space-time was in a sort of singularity, time experienced everything at the same time. Everything was everywhere, folded on everything. So time had to be anytime, all the time.<br /><br />You can shoot me now. <div class="Discussion_UserSignature"> <p> </p><p> </p><p><span style="color:#ff9900" class="Apple-style-span">-pyoko</span> <span style="color:#333333" class="Apple-style-span">the</span> <span style="color:#339966" class="Apple-style-span">duck </span></p><p><span style="color:#339966" class="Apple-style-span"><span style="color:#808080;font-style:italic" class="Apple-style-span">It is by will alone I set my mind in motion.</span></span></p> </div>

 

[weeman]

By today's theories, time began at the same time as the big bang. However, this is just theory, so we can't say for sure when time began. If you believe in a cyclic, reoccuring universe, then there is a good chance that time is infinite. If there has always been a universe expanding and contracting, then time would have always been. <div class="Discussion_UserSignature"> <p> </p><p><strong><font color="#ff0000">Techies: We do it in the dark. </font></strong></p><p><font color="#0000ff"><strong>"Put your hand on a stove for a minute and it seems like an hour.

[serak_the_preparer]

I believe weeman is right. In an inflationary universe (or multiverse), it's worlds without end and no beginning or end of time.<br /><br />Eburacum45 is also correct that this discussion is probably better suited to a different forum. There is already a long-standing discussion on the topic available on this thread: Does Time Actually Exist? You may want to check it out, if you have the time.

 

[spacekud]

So what does our Universe do Expand and recontract on itself over and over???

 

[serak_the_preparer]

Recontract? Maybe not. Expand forever?<br /><br />(Again, I recommend boards like Ask The Astronomer and Space Science & Astronomy as good places to look for discussions and material on this subject.)

 

[deapfreeze]

I am starting to feel that if we go far enough into the universe we will just arrive back where we left from at a different time. Kind of like going in circles. <div class="Discussion_UserSignature"> <p><font size="2" color="#0000ff"><em>William ( deapfreeze ) Hooper</em></font></p><p><font size="1">http://deapfreeze-amateur-astronomy.tk/</font></p><p> </p> </div>

My own mod to various theories is this:<br /><br />Our known Universe is a collection of galactic clusters floating in the void of space. This void of space contains other galactic clusters banging into and out of existence. The next nearest one to us might be 90 billion light years...or 220 trillion light years who knows. Endless clusters banging in, existing, then going out at various times within the endless, and timeless void.<br /><br />Of course, I cannot prove it, I cannot even provide much in the way of supporting data. The scientists have me beat where data is concerned. But even they tell you they do not address what came before the bang because they have no data for that. <div class="Discussion_UserSignature"> <p><strong>My borrowed quote for the time being:</strong></p><p><em>There are three kinds of people in life.

[derekmcd]

Current thought is the Universe is flat, in which case, you would not arrive at the same point. Parallel lines will always remain such. Of course, they use terms such as 'nearly' flat, or within margin of error of the intruments. Truth is, we can't be sure about the entire Universe vs. obserbable Universe. I can stand on a football field and tell you it is 'flat'... I can even measure it to back up my statement. My instruments, though, are not fine enough to detect the ever so slight curvature of the earth that may be present. I, too, like to think of the universe as closed... sure makes answering the question "what is at the edge of the universe" easier to picture. <div class="Discussion_UserSignature"> <div> </div><br /><div><span style="color:#0000ff" class="Apple-style-span">"If something's hard to do, then it's not worth doing." - Homer Simpson</span></div> </div>

 

[serak_the_preparer]

Did a little digging on the site regarding your expansion question. Found this thread over in the Space Science & Astronomy forum:<br /><br />Why does the universe expand?

 

[Gary_Peck]

<p>Hi Everyone,</p><p>Time is a universal mass of movement that is constant everywhere. We base time on our Earth's rotation around our Sun. You cannot apply this to other worlds & space. Its like trying to condense the Entire Earth's existice of&nbsp;4 billion years into a 1 year timeline. Where would you fit the existance of man.&nbsp;We would not even fit between a second. </p><p>Time as we know it (hours, minutes & seconds) is designed for humans living on Earth. We are comfortable with it. It is not a proper & true measurement of time. Time is travelling so fast&nbsp;we cannot capture it at it's slowest point. It never stops moving. We measure things in&nbsp;Hundreds, thousands & millionths of a second. These measurements are innacurate. We assume it is near these figures. That is why we have discrepencies. Did the Dinosaurs exist 60 million years ago. It could have been 58,768,426 years ago. Trying to make sense of Time & space from our point of view is going to create discrepencies.</p><p>Gary</p>

<p><font size="2">Welcome to SDC. That's an&nbsp;interesting post. Time is such a complex topic that even the Wiki page on Time runs around 10,000 words. There are so many aspects to it, it is nearly impossible to discuss all of them in one thread.
