Time is slowing downPage 1 of 2    (1, 2)
As we know, the universe is continuously expanding from a central point. As this universe expands, using light as an example, will stretch out and expand as well. Light for those of you who do not know, traps pictures similar to a natural camera. You can literally trap events in light and these events will travel with the light at light speed. If time expands, the particles and waves that make up light will also expand. The distance between each particle/wave will lengthen the more the universe happens to expand. Light is a direct correlation with time. The more our universe expands, the more light stretches out and captures pictures for a longer time than normal.

In my conclusion, the expanding universe is causing time to gradually slow down.

Light doesn't travel in the time dimension; all its velocity componants are in the spacial dimensions, leaving a zero length vector in time. Consequently, a photon travels no distance in time.

To the best of my knowledge, there is no indication that the expansion of the universe is in any way affecting the velocity of light. I suspect we'd notice the change if it did. That said, most of the universe will be forever invisible to us because the velocity of recession far exceeds the velocity of light.


If time expands, the particles and waves that make up light will also expand.

Time is only a dimension of spacetime, moreover, it is one in which light doesn't travel, so I don't see the expansion of time as any more than the expansion of one dimension of spacetime. I also fail to see how or why light itself should "expand" just because the universe is expanding.

The more our universe expands, the more light stretches out and captures pictures for a longer time than normal.

With respect to what? Time doesn't pass for the photon, so it doesn't matter how far it travels. The passage of time is a local and relativistic phenomenon resulting from a relative velocity, a componant of which is in the time dimension.

I think what you are trying to say is that as the universe expands, so does time, which is correct, but an increase in "acreage" doesn't make the plowing any faster (or slower), if you know what I mean.

In my conclusion, the expanding universe is causing time to gradually slow down.

I'd say the conclusion is erroneous; it would be more correct to say that the expanding universe is "giving" us more time.

But it does take longer to get from point A to point B.

In that A and B are moving farther apart owing to recession, yes.

Not an expert, but...

Photons experience time at the same rate we all do- 1 sec/per sec.

It takes the same amount of time for me to get from the top of my driveway, to the bottom, no matter how big the universe is today.

Then I would say, the fact that the universe is expanding, does not mean that the length of my driveway is expanding. Point A to point B does not increase, if they are both in my driveway.

Explain to me how photons, or as you put it light, trap pictures similar to a camera? Photons reflect off of objects letting us see the world around us. Now photns that are emitted from distant stars, reflecting off elements somewhat close to them and then traveling to us will have happened however many light years away the photon has traveled before reaching us. No, reading your theory more is making it even more absurd. Yes the universe is expanding, thus further stars producing photons. And yes these photons will take how ever many light years away they are to reach us. Just because photons are traveling more and more light years from start to reaching us does not mean photons are streching. Shit now I am starting to sound like i don't know what I'm talking about and that cause I don't really. Take a Astronomy course or read up on your quantum mechanics. Time is also defined as many different concepts and theories. So yeah in a way your little slow down of time idea is possible but then which time do you mean.

Verzen, you are right.
If the distance between A and B gets bigger, time slows down to keep the speed of light constant.
But we still need to use the same two points A and B as a reference, to accurately calibrate ourselves to keep time.
So as A and B get bigger, if it took us a year to walk from A to B, then we call the time to walk from A to B as a year, even if that is much longer than a year previously.

We would notice the difference. Only that since the universe is continuously expanding, everything is staying in proportion, and only the scale increases. So as our "year" increases, so does the orbit of the Earth around the Sun, keeping it 1 "year". So does the rotation of the Earth, keeping it 1 "day", 1/365th of a year. Everything stays in the same proportions, so if all of those measurements increase, we would not notice the change.

So yes, time is slowing down. But in such a way that we have absolutely no idea that it could be 1 trillionth of what it was a second ago.

Uhhh, how so?

If A to B increases, the photons take longer to get there. The speed of light is unaffected.

As for time, concepts are unaffected by distance.

Time is slowing down

Not for me! At my age, the years are going by like weeks. At this rate I expect to die of old age in a few more months!

@ Funcuz
Far be it from me to give advice, but if I were you, I'd light up. Might as well live a little before you croak!

In my own case, I want to die drunk. When you think about it, it's kinda win win; I won't wake up with a hangover... and it could be days before it dawns on me that I died!

Where did you get the idea that light "captures" pictures?
As for the notion that the expansion of the universe is causing time to slow down (actually a meaningless statement... "time" is not an object in motion, so it is not correct to speak of it as speeding up, slowing down, or maintaining a steady pace.
As far as I understand (not very far), time has been shown to be relative to GRAVITY, not to photon distribution.

Looks like I'll miss the stories behind the headlines on Friday night's news. Pity.

That's one of the pluses of being dead...We won't have to listen to the bullsh¡t anymore.

Because that's what it... does? If you're 700 light years away from earth and you zoom in on earth with an extremely powerful telescope... we could watch the Crusades happen.. Just by being 700 light years from earth.

you may have to do some extra research for better details. That's jsut what I've come across.

It's the first I've heard of it. Can you cite a source?

Actually, according to Stephen Hawking, the universe is no longer expanding. We are now in the final stage. They forgot to factor in the "echo" effect.


Actually, the universe is continuing to expand and recent observation even indicates that it is accelerating.

what is it that is expanding?

Spacetime itself.

When we speak of the expansion of the universe and the red shift that indicates it, it means that on the whole, everything is moving apart. It doesn't mean that things bound together by gravity (like individual galaxies, or even galaxy clusters) are moving apart, some are moving together (the Andromeda galaxy, if I recall correctly, is actually approaching the Milky Way, not receding from it).

Maybe a good (maybe half-assed) analogy is that of a circular, fenced ranch. The farmer (big bang) expands his ranch by moving his fence (event horizon - end of visible space) farther from the centre. As he does so, the average steer (galaxy) moves farther away from the other steers (new grass for grazing? - hell, I don't know!) and the ratio of cows per acre declines. Many steers have friends & little cliques they belong to (galaxy clusters) and tend to stick together. They aren't moving any farther from each other, but most of the other steers & cliques are moving away from them. One day most of the steers will be so far from all the others that they will disappear over the horizon like a ship off to sea. At that point all the cliques & many individual steers will feel like the only ones left, because they can't see any of the others.

What you have described is a re-location of stars, planets, etc., moving further apart from each other. So the universe itself is just sort of thinning out. My next question would be, why are we assuming that the only things that are out there are those that we can detect by some method or another? AND, if there are more things than we know about, then could the things that we do know about be encroaching, on a galactic/universal level, on other stars/planets,etc???


Here's the problem. We have an observed phenomenon with no actually observed mechanism. The phenomenon is the accelerating expansion of the universe. The mechanism, however, is the question.

The fact of the matter is, stars and planets remain relatively unchanged in their orbits in their galaxies. The galaxies are "spreading" further apart in the sense that the space between them increases. And yet, the "energy budget" of the universe remains the same per unit of measured "empty" space.

there are things that "appear" to be affecting local space. Like the "great attractor" in the direction of Centaurus. So something not visible by conventional means is preferentially pulling galaxies locally toward it, even as the universe itself expands.

You're equating time to the particle/wave phenomenon of light. This is incorrect.

The exact "nature" of time is not known. However, attempts to find "quanta" of time have been unsuccessful.
