Why does time generally seem to pass faster as one ages?

As a kid, there always was so much time.  As a adult I've found that I'm always in a hurry...on a schedule.  Time just seems to fly by now.

You are traveling in time as you read this, You may adjust how fast you are traveling by slowing or increasing your velocity. Alternatively you may do so by subjecting yourself to a strong gravitational field. You may not travel in another direction. No matter how you adjust your travel through time relative to an outside observer from your own viewpoint time will seem to pass at the same pace.\n\nPlease consider becoming a member of my group at http://groups.yahoo.com/group/EarthII/

Gravity.  Clocks run slower in a gravitational field. Plus whatever velocity difference there might be.

Rabid_Scientist is entirely correct.  Both you and your home see time in the other place as speeding up.  I do have something to add to that though.  If you maintain a constant velocity, it can only be measured relative to some other point of reference, so there is no way to determine which is faster, and consequenty it cannot be determined whose time is actually going faster.  However, if you are accelerating it's a whole different story.  As you speed up to that super fast speed where the time differental starts to be noticable, you will see time on your home planet speed up and they will see your time slow down. (Sorry, I'm not going to try to explain this, I'm not sure I entirely understand it myself).  If you were to go back to your home planet, far more time would have passed for them than for you.  This effect will be greater with greater acceleration and greater speed so in that regard time will pass on your home planet more quickly the faster you go.

A light year is measured by the time on Earth not by your watch.  However, since one light year is the measurement of the distance that light travels in one Earth year, then one light year always equates to one year on Earth.  So, if you travel one light year, you should be one year older and the Earth would also be one year older (assuming no time anomalies, like a black hole, are encountered during the trip).  Keep in mind that a 'light year' actually measures distance (based on the speed of light).  \n\nHowever, time is always relative to where you are.  So, for you, time progresses at the same rate it always has (for the human body) no matter what's going on around you.  So, if you were gone for 3 minutes (clock time), you'd be three minutes older.  If you were gone for 24 hours, then you'd be 24 hours older.\n\nHowever, if you were to visit the proximity of a black hole, the theory is that time slows down.  So, while your watch may continue at the same rate as it always has (your time has actually slowed down).  So, time on Earth would be progressing at a much faster rate relative to you (even though Earth's progression is normal to them).  So, if you returned to Earth and your watch was only 12 hours later than when you left, time may have progressed days or weeks on Earth.  In which case, your body would have aged 12 hours instead of the days or weeks that it would have progressed if on Earth.

*sigh* Another debatable query enslaved to the limited senses of us mortals, yet forced in all its calamity by our fascination. Here goes.\n\nEinstein shook the fundaments of the Scientific Community when he introduced his Theory Of Relativity and Special Theory Of Relativity back in 1905. He was considered everything from Nostradamus to Jesus. This pinnacle of his life was not attained in mere pondering. Let me expalin to you this fragment of his theory.\n\n  In theoretical suppositions, the space-time connoction bear themselves in alliance. Any change inflicted on one dimension is prone to affect another.\n\n When we say that we will only age a bit, while the Earth has conquered years and decades, we mean to say, that, time being relative to every individual, along with its flow, may hasten up, if we start to function at a velocity of extremes.\n\n If time IS relative (No humane way to confirm), then a higher velocity achieved could result in a hastened flow in the fluid of the "Fourth Dimension" of time. Such relativity was all that he wished to make us understand.\n\n As far as the aging is concerned, provided that we have armour to protect us from the friction effects of such a speed, we are going to age alright. Since our molecules are being relative to the molecules of the rest of the universe, they are not going to change much. Yet RELATIVELY they will alter a decade or more (backwards)!\n\n*sniff* Einstein, I salute you!

It is a real effect and can be important in particle accelerators where subatomic particles are going close to the speed of light. It turns out that the radioactive particles decay slower when they are moving at these high speeds. So it doesn't just appear that time slows down, it really does.\n\nThis is a consequence of special relativity where there are two basic assumptions:\n1) All motion is relative...you can't tell whether you are moving or everyone else is.\n2) The speed of light is the same to everyone.\n\nThe first assumption was true for classical mechanics, but the second was not and is what makes all the strange results of relativity. In some sense, it turns out that someone moving with respect to you has time and space 'rotated' with respect to each other. This makes both space and time measurements different for you and them. Two events that you see as being at the same time or place won't be for them. Two events they see as being at the same time or place won't be for you. The slowing of time is an effect that only applies to events that either you or they see as being in the same place (or very close by). Otherwise more complicated computations have to be done to determine how each sees things. Look up Lorentz transformations.

The trouble is that any answer to that question is guess work at best.\n\nWhether that guess is based on scientific observation or pure mythology or religion...  It's still pure guess work and any one answer is as valid as the next...\n\nBased on the fact that the passage of time is variable dependant upon the effects of Gravity and/or Speed...  Every answer is true.\n\nFor the passage of time in a Gravity free vacuum, the universe infinitely old...  For the passage of time for the very first photon released - The Universe is only moments old.\n\nIf we look at the physical evidence and declare that it would have taken 16 billion years for this, or that...  We are talking about the time experienced by those things...  But that measurement is no more valid than the mere momments of the photon or the infinite eternity of the vacuum...\n\nNo...  The truest answer I can give you is this...  The universe you live in came into existence at the momment of your creation.  So it's aproximately nine monthes older than your age, but it was created with all the appearences of having existed previously...

As Einstein said you get time contraptions if you move at a speed aproaching the speed of light. For you time moves faster. You move a year with a speed close to the speed of light and when you stop everyone will be 7  years older and you've spent only one year. The problem is...what if you don't like the future....there is no way to go back in time..

we r travelling at 1 second forward per second.\n\nIf that's not that u meant, the easiest and most likely way to get a time machine to time travel is for yourself in the future to travel back now to give yourself the time machine now which u got in the "past" from the "future yourself" coming back to gave it to u.

well, we all assume that time flows in one direction and one thing follows another. Maybe that's just the way we see it. Try to imagine that you were a cartoon, 2D on a page, you have no concept of the 3rd dimension. If we could se everything that had happened at once, time wouldn't be linear but I digress. In effect non-linear time means that one thing would not necessarily come after the other e.g. I wrote this 'before' you asked the question.

The same time as it was one second ago. The only reason it would change would be if the time was like 8:21:59; one second from that would be 8:22.\n :)

So far time dilation is possible in the forward direction. That is if YOU travel away from earth in a very fast spaceship near the speed of light then turn around and come back. The people on earth would age more then you have. YOUR clock would be different then those people on earth. It would be faster.\n\nGoing backward in time is still up there.\n\nThere are many experiments that prove this to be true. Atomic clocks capable of high accuracy are sync up. One is put on a plane and flown around the earth at high speeds for a long time. When the two clocks were compared later, they showed a difference, a very small difference but a difference none the less.\n\nTake a look at this website. There are plenty of other site out there.\n\nhttp://imagine.gsfc.nasa.gov/docs/ask_astro/answers/050225a.html\n\nInterestingly, if you did travel at the speed of light, you would be anywhere and everywhere all at once... WOW! That blows my mind.    :-)

cause things get older not younger.

Due to gravitational time dialation.... humans would actually age slower on Jupiter then say... on earth.  This is because the more gravity there is, the slower time moves because gravity is the warping of space-time.  Now if you somewhow lived on jupiter (not possible really because of the lack of surface, high gravity, and pressure), it would seem people on earth would age faster.  I'm not sure on the differences but it would probably only be in seconds over a lifetime.

Because a young person's frame of reference relative to time is very short while an older person's is much broader with presumably a more mature appreciation of things past and events to come. When you have more years behind you than you can reasonably expect ahead of you ,then it gives one an entirely different perspective of the term 'time' . I can only advise that time is a thief; if you have dreams then the time to act on them is NOW. You really don't 'have all the time in the world'.

Yes.  It means that for the twin that stayed on Earth, the time really passed for him, and for the twin who traveled, less time passed.\nThe older twin doesnt just "look" older, he really is older.  He really experience that time. And the younger twin really experienced less time passing.
