Do you ever get the feeling Time is standing still or does your mind get so busy with so many things going on, that you wish Time would stand still?

time?? huh?? where???? i saw it fly by a few times....... never stopped yet....... lol

 

i have stopped to think and forgotten to start again one time but never seen time fly before...is it like when pigs fly??

 

Time flies like an eagle.
Fruit flies like a banana.

You’re experiencing physiological proof of Einstein’s theory of relativity. Basically this means that the time you perceive, as compared to measured time, is your own place in time. This is why we use clocks to measure static time, time of distanced traveled to measure linear time, and the speed of light to measure theoretical time and distance in space.

Notice I said theoretical time and distance in space. This is because we really don’t know if light travels at the same speed throughout space. We know, for example, that a plain glass window slows down the speed of light (noted as C) when the light is traveling through the window, relative to the outside observer, though if you were an atom within the glass light would still be moving at C. Light slows down in glass because glass is nothing more then a high viscosity fluid, and like water, traps some light within it.

But there is also a physical reason why you might feel that time has slowed down, because it can! Einstein proposed that time travels on a linear path throughout space, but becomes curved by objects of mass. Because time is fluid as it passes the object of mass it speeds up. When it leaves the mass’s gravitational field it slows back down to P (P is the noted symbol for time). From reading this you would think that on earth time would go by faster then time in space, and it does! This was proven during the Apollo space missions.

As the astronauts moved farther from earth the clocks in the Apollo spacecraft would slow down by a factor of X relative to their distance from earth. As they approached the moon they would speed up by a factor of X compared to their distance from the moon. On the moon the clocks were still measurably slower then the clocks on earth. This was all doing to the difference of the earth’s mass compared to the moons. How can this have a physical effect on you?

It is proven that the earth’s gravity is not the same in every location and changes dependent on the earth’s core. As the core spins deep within the earth heavy metals are flowing. The weight, and location, of these heavy metals has an effect on your perception of time. At any given point there are over 900 variations of gravity on the earth’s crust. If we were to assign the number 1 has the mean value for the earth’s average gravitational pull, then this variance can be from .0001 positive to .0001 negative of the mean.

The last thing we can notice within our bodies is the location of the sun. Ever notice that some people can tell the time without ever looking at a clock? What they have the ability to do is feel the location of the sun. Ever notice that days fly by but nights can drag on forever? This happens for the same reason. When we are facing the sun (daylight) the suns gravity has a slightly increased tug on our (personal) mass. This cancels out part of the gravity we feel from the earth, and thus speeds up time. The opposite happens when we’re facing away from the sun. We feel a little more of the earth’s pull and time slows down. People on working on third shift feel it the most.

The one thing to remember that this is all relative to the person, your perception of time is your own. We all have different bodies, live in different places, and perceive time in different ways.

 

OK, so what happens when the referee calls "time out!"

Just kidding. Interesting post.

 

I thought I heard Hawkins was going about the earth not having that much gravity to affect time, you would need to go near a black hole or neutron star to see any *appreciable* difference? Maybe the high speed travel of the apollo rocket could account for the time shift. Don't you have to go like 30,000 mph or something to be in orbit? That's fast enough to affect time.

I don't know, those days at work can really drag sometimes and the nights after don't last very long to me.

neat little article on time travel http://www.sciam.com/article.cfm?articleID=0004226A-F77D-1D4A-90FB809EC5880000&pageNumber=1&catID=2

 

A couple more links that are interesting

Off the subject of Einstein, but still on time, I once saw a show on Discovery about how animals perceive time. Alot has to do with the temperature of the body; however, being mammals, we don't vary too much. But reptiles and insects, apparently, can miss out on alot. That is why birds wait till the evening to hunt insects, because its cooler and the bugs are easy to catch. The bug doesn't even know what hit it. On the show, they had this tower that contained bees, pidgeons, and outside was a turtle. They blew the tower up and the bees and birds got out of the way in time to escape injury, but the turtle didn't even react, just kept on walking like nothing happened. Really neat show, I'd like to see it again.

 

I'm reading this book right now, called 'The Arrow of Time'. Alot of strange things in there, but if I understand it, if we were to travel the speed of light, time would stand still. There are so many different theories, though, and I think I have to re-read it. Time and light are very closely linked, though, along with not only gravity, but more specifically, matter. I love Quantum Mechanics, but I think I waited too long to get into it.

The sun & the earth pull on you no matter which way you're facing, and the difference in the pull on your body/brain/(anything that could sense gravity depending on your direction) is so small that not even Einstein could come up with a theoretical formula to describe it. The changes in the earth's gravity are greater, so if you could feel the location of the sun, it would be like feeling the wake from a fish swimming a mile offshore while standing in the surf zone.

>if we were to travel the speed of light, time would stand still

Not really. Time goes on no matter what, and the speed of light is relative, and also dependent on which frequency of light you choose to examine. In the same way that the Doppler Effect affects your perception of sound, it affects your perception of light - if you speed up to the speed of light relative to the surface of the earth, all the light that you COULD see from here would effectively STOP, meaning you couldn't see it any more, because its frequency relative to your eyes would be zero. What you WOULD see would be the light that was X-Rays relative to the earth, but which would then be visible light frequencies relative to your eyes. So if you COULD still see the light from earth, it would appear that everything was stopped because you'd be moving along with the light from only one moment. If you took a step toward earth inside your speed-of-light space ship, you'd see the light from a fraction of a second later - step away and you'd see a moment earlier. But time would be plodding along back here on earth - you just wouldn't see it that way because your perspective would be too different.

 

Carl Sagan had a flic I saw once where he went on about these sorts of things. I remember the depiction of a guy on a bike that could travel the speed of light. He claimed as bike approached the speed of light, the guy would experience tunnel vision. The tunnel would be getting smaller and smaller until he reached the speed of light, at which point the tunnel would be infinitesimally small. Those on the outside, as the bike was approaching the speed of light, would see him with a red shift as he was coming towards them and then a blue shift as he was travelling away from them. And, after maybe 20 minutes or so relative to the guy on the bike, he would return and find his friends were very old. Seen this about 15 yrs ago, but remember it quite well. Also, in 15 yrs, I have never forgotten the speed of light, 186,282 miles per sec or about 300,000 Km/s. Now, if I could only remember casting numbers as well.

 

In order to prove out Einstein’s theory all one has to do is watch a solar eclipse. As the moon breaks from totality you can see the light being bent around, so that it covers part of the face of, the moon. The only way to explain this is that the moons gravity is pulling on the fabric of space/time. If you believe in Einstein’s theory that light has no mass and, thus curves with space/time, then you have to agree that the moon is bending both space and time.

The speed did have a part to play in the amount of difference that the clocks were off, but when the clocks on the moon were reset to standard earth time they still moved slower then the same clocks on earth. The only way to account for this would be for the moons lower then earth’s gravity. BTW It is not the speed that rockets travel that makes it so they can leave earth’s gravity well, it is the power they have. There have been a number of aircraft, the X-1 and X-12 to name a couple, that have entered low earth orbit (158,400 feet or 30 miles above sea level). But in order maintain orbit you must reach a speed that equalizes the pull of the earth^2 –1G (earth’s gravity squared minus one gravitational unit).

Now here comes the part that blows Hawkins’s suggestion out of the water. When the space shuttle goes up the clocks do not loss time as fast as those on the moon. If Hawkins’s theory were correct then the shuttle should loss time at a rate equal to the speed that the shuttle is traveling. If you were to graph it out, a plane traveling at 1740 (mach 2.65 or 10% of the space shuttles needed 17,400 mph to maintain orbit) should lose 10% of the time the shuttle clocks do, and NASA has proven this doesn’t happen. The only explanation for this is that gravity plays a bigger role in time then speed does.

 

The sun & the earth pull on you no matter which way you're facing, and the difference in the pull on your body/brain/(anything that could sense gravity depending on your direction) is so small that not even Einstein could come up with a theoretical formula to describe it. The changes in the earth's gravity are greater, so if you could feel the location of the sun, it would be like feeling the wake from a fish swimming a mile offshore while standing in the surf zone.
__________________________________________________ __________________
First I can prove my point on a very large scale. All you have to do is think of tidal shifts and their cause. Inasmuch that the moon’s relationship relative to the earth moves the ocean by gravity so to can the changes of gravity have an effect on man and his focus on time. I used the sun to describe this effect because its relative position (has compared to where you are standing at any one given point in time) changes at a greater rate then the moons position. In Einstein’s theory we must realize that both time and gravity are elastic.

When you are facing the sun, or moon if you choose this as your gravitational point of reference, you are in fact 3500 odd miles closer to the sun/moon. Thus you feel more of the gravity pulling on your body, and as such defeating a part of earth’s gravity. Can this have an affect on our behavior? From a physiological point very much so, just ask a policeman or people who work in an E.R. what the busiest time of day, (for the sun’s effect) or the month (for the moon’s effect) is. Between 3-5 Pm for the sun (because of the earth’s tilt we are actually closer to the sun at these times) and 10 PM- 2 AM for the moon (because we are closer it does have a great effect). If you notice these times frames are also the ones that seem to last the longest for most people. Thus we have the tie in between the sun and moon, physicality, physiological, psychology, time and gravity.

 

I don't know man, I think your way out on a limb with that gravity thing. Keep in mind that the moon is traveling quite fast relative to the earth, as well as anything in orbit. A rocket must accelerate to at least 25,039 mph (40,320 kph) to completely escape Earth's gravity and fly off into space (regardless of power - power has to do with how fast you accelerate, acceleration is the fundamental, F=MA). Orbital velocity is the velocity needed to achieve balance between gravity's pull on the satellite and the inertia of the satellite's motion, this happens to be approximately 17,000 mph at an altitude of 150 miles.

I'm sure when the shuttle takes off, they have all their ducks in a row concerning the clocks by now.

I have heard that clocks carried in MACH jets lost time when referenced to those on the ground. Is this due to the speed or the lack of sea-level gravity? I put my money on speed, since slower planes don't experience this loss.

As for the light bending around the moon, does the phase diffraction ring any bells?

I do agree that the moon does "bend" space and time, but not because the gravity of the moon has any significant effect on light. If that were the case, how could a star shine w/o pulling all the light back in like a tractor beam in a mid 80's startrek film? The moon has mass, like any other matter, and therefore "bends" the space time fabric. A black hole is the only thing I know of that has any significant effect on light. By the way, Hawkins was the one that first conjectured the existence of black holes and won a bet with "can't remember guy's name" and got a subscription to playboy as winnings. I would make very sure I knew what I was going on about before taking Hawkins on. Some have tried.
