Why Does Time Fly?

It just sounds like you are ignoring the effects of time dilation and contraction, as well as the effects of each individual's unique frame of reference.

time dialation doesnt have to be matter living in a different 'bubble zone' of time. It could simply mean the atoms themselves are operating at lower speeds. Giving the impression that it is traveling into the future.

It would be interesting to send a small satalite into orbit that contained a device that was set to go "DING" in 1 year if it were wound up here on earth.
Then send it to space and wait for the signal of it to go ding. It should according to equations go ding on earth at a later time. But inbetween the beggining and end of the devices life have sub-dings (signals) that go off to measure if when they come to us here on earth. An ever increasing time between the expected dings should occur and match the prediction of the time dialation equations. And when all is said and done compare it to the measurements the device performed on earth. Not necesaraly atomic clocks. But very consistant devices that send a signal exactly on expected time.

So do you think that we are somehow seperate and distinct from the atoms themselves? I personally do not.

As for the "dinging" satellites... happens all the time. Our satellites have to continually readjust their clocks by an amount exactly predicted by Einstein's equations to ensure they are properly synched with the clocks on the surface of the earth...

Why does time fly? This is a concept of mans mind. Time is measured with a tool of man creativeness, seconds, hours etc. Man has chosen to use this time tool to measure the regularity of events he has observed around him, over the milleniums. Eg, the rising and falling of the sun and the speed of light in more recent 'times'.

Why does it fly? Thats because man doesn't allow himself enough time to smell the roses ( etc ). He prefers to fill his time with less enjoyable things. I hasten to add that not all men ( and women ) experience time as 'flying'.

Yes I think there is a seperate part for the existence of consciousness. I constantly bring up the mention of color. It is created, but by what? do the atoms in your brain know how to make blue, red, white, etc? and of course even if they could what intelligence decided to create the color as a color. They are not part of the physical world, something that is part of you creates it from the input around you.. alot like feeling.

about the satalites, true enought they do have lots up there. The experiment would be slightly different than satalites and clocks though. However, I think after reading more on general relativity I can understand now how Electromagnetic Radiation (light) can be dialated, or changed. However from some thought experiments I feel that the idea that time is being changed compared to considering the signal being changed is something to consider.

If for example, a star exploded right now a few thousand light years away, did it really happen right now? the same time to us as it did to it even though it will take a few thousand years for the evidence to get here. I think so. So, the does the satalite really travel into time? Well with idea of curvature of space from the earth, and from other tests, its shown that the speed of light (satalite signals) can be altered as it traveles through the multi-dimensional space time curvature from up in space down to earth.

Also, could there be a difference between a satalite moving according to where your standing at rest and a satalite that looks to be at rest but is actually orbiting very fast and far enough away that it matches the speed of your rotation on earth. I suppose I mean, does the dialtion occur from simply an object moving or an object moving according to your frame of rest.

There may be some emmergent phenomena, but considering our limited understandng of consciousness we cannot discuss this with any final resolution. We may be more than a collection of atoms, but a collection of atoms describes us too. If the atoms change, so do we.

Time is a lot like consciousness. Is many things. Heck, just browse multiple posts on this forum alone, and multiply that by the infinity of other discussions and thoughts that exist regarding the nature of time in the world.

The signal changes. Yes. One concept of time is a measurement of change. Yes. However, there's no sense arguing if it's possible or not to dilate time, as it's been repeatly verified already.

Time is not like the freeway, or a tunnel. If it is, it's not ONLY like a freeway or a tunnel. The satellite doesn't travel "into" time, but the local passage of time for the satellite is different than for an observer in some other frame of reference (like on Earth or in a vehicle moving even faster than the satellite is).

Besides... it's always right now. ... and now... ...and now... ...and now... ...a...n...d... ...n...o...w... ......a......n......d...... ......n......o......w......

I am struggling a bit with your phrasing here, but I guess the easy answer was given by big AL himself... "EVERYTHING is relative."

Hello,

According to COBE measurements our Earth is moving towards Leo constellation using speed of 400 km per second. The Milky Way is moving towards Crater, the speed is 600 km per second (some older sources talk about Centaurus - Hydra). See image:

It is quite a coincidence that the angle between Earth cruising path and the Great Void in Eridanus constellation is 90 degrees ! See image:
http://www.antti-roine.com/download/...d=96&mode=view

The giant void may be the center of our universe. This means that fictional Great Attractor in Centaurus-Leo direction is not needed. Ofcourse this is only a logical guess, but most of the scientific facts have been found by testing logical guesses.

No, every point in the universe is the center of it's own observable universe.

APOD: 2008 March 9 - CMBR Dipole: Speeding Through the Universe

Our Earth is not at rest. The Earth moves around the Sun. The Sun orbits the center of the Milky Way Galaxy. The Milky Way Galaxy orbits in the Local Group of Galaxies. The Local Group falls toward the Virgo Cluster of Galaxies. But these speeds are less than the speed that all of these objects together move relative to the cosmic microwave background radiation (CMBR). In the above all-sky map from the COBE satellite, radiation in the Earth's direction of motion appears blueshifted and hence hotter, while radiation on the opposite side of the sky is redshifted and colder. The map indicates that the Local Group moves at about 600 kilometers per second relative to this primordial radiation. This high speed was initially unexpected and its magnitude is still unexplained. Why are we moving so fast? What is out there?

Why Does Time Fly?

Because we're stuck.

It is psychological time that appears to fly, and it flies faster as you age, and also when you do not think about it (time, that is). So, for a child, the order of succession of events in life (what are called moments) appears to go forth slowly, but as you age, the apparent speed of these moments goes by much faster, why ?, because as you age you realize that the "time" to the end of your existence is much closer than when you were a child. Now, since time is that which is intermediate between moments, clearly, the moment of death is a shorter time in the future (on average) when you are age 75 then 7, so time appears to fly by for the 75 year old relative to the 7 year old.

And, have we not all experienced how fast time appears to fly in our minds view when we are busy with some task where we do not concentrate on the "order of succession" of the moments. So, between two moments, say A ---arrow of time-----> B, the same arrow of time length will appear to fly by for the person that is not concentrating on the order of succession of the moments between A and B. This is how I see the OP question.
