Is there Such a Thing as TIme

The present moment is real. However much you may remember the past or anticipate the future, you live in the present. The next second of your life is the future. Of course, the moment during which you read that sentence is no longer happening. This one is. In other words, it feels as though time flows, in the sense that the present is constantly updating itself. We have a deep intuition that the future is open until it becomes present and that the past is fixed. As time flows, this structure of fixed past, immediate present and open future gets carried forward in time. This structure is built into our language, thought and behavior. How we live our lives hangs on it. Does mans concept of time meaning, seconds, minutes, hours, days, weeks etc etc fit in with the flow of the universe

Its cliche but it is an illusion

the ony "time" you have is in the NOW and its all you will ever have

because of the different quatum possibilities that exist in the universe the future doesnt and cant exist technically its all illusion

lucky that our neurons do not operate at the speed of light, and have inertia build in to their chemical component, otherwise time, the moving moment would really appear short to us.

Time is not a thing, material, but it is real, an entity, appearing twice in the famous equation E=m squared.

It is easier to think that time is fixed and WE are MOVING, not the other way around, because

We all travel through time at different rates, as observed, depending how fat our surroundings are and how fast we travel throgh space, it is like,-- not everyone has the same speed down the freeway.

gmjalmt: --the open future--? with fixed time, the future , like the pavement,-- stretches ahead of us, untravelled, we are not in the past anymore, but if there is a surveillance camera back there, your image might be recorded there. speeding even.

that image would be called a fossil, not more than a dead image of you of your past.

You sure do make an effort to sound smart!

Captain, -- drole^ not a troll, just answering a question. and

the follow-up question is: If time is compared to a highway? how far does the pavement stretch into the future, and into the past and:

since the time axis in our presentations is at 90degrees to the space-line, are we moving at an imaginary 90 degree vector to space as we age?

I am impress. Anyway, time is tricky.

In a recent experiment, scientists placed two atomic clocks on two tables, then raised one of the tables by 33 centimeters, and found out that the higher clock was running faster than the lower one at a rate of a 90-billionth of a second in 79 years.

This is called time dilation, and it happens because (as Einstein's theory of relativity predicted) gravity warps time as well as space. The closer you are to the ground, the more you are affected by the Earth's gravity and the slower time moves. On the other hand, as you get higher, gravity's pull weakens and time speeds up.

Keep in mind that this is an insignificant amount of time we're talking about here. It has absolutely no bearing on your life, unless you rely on GPS equipment. Because a clock inside a GPS satellite runs at 38 microseconds per day faster than the same clock would run on Earth, a computer has to constantly adjust everything to make up for that difference. Otherwise the consequences would be disastrous: In only one day, the entire system would be off by 10 kilometers, and it would just get worse from then on.

Oh, and by the way, gravity isn't the only thing that can mess up time ...

Another thing GPS satellites have to take into account is speed, the faster you travel, the slower time moves. Scientists have proven that the same thing happens to you every day, on a much smaller scale. Making one of the clocks move at only 20 mph caused it to slow down its tick by almost 6 x 10-16. In numbers we can understand, that translates to "Not a whole lot, but still".

So, let's say you're driving to work at around 40 mph, that right there is apparently enough to cause time to move 0.0000000000000002 percent slower than it would if you were standing still.

In another experiment, one atomic clock was taken on a plane trip around the world while the other one stayed home. Even though the clocks were perfectly synchronized at first, the traveling clock came back from its 50-hour, 800-kilometer trip missing 230 or so nanoseconds.

So the clock gained time from being farther from the Earth than the other one, but it lost even more just by going faster. What's even weirder is that from the perspective of the clock on the plane, the clock back home is the one that's running faster than normal. You don't actually feel time slowing down or speeding up: Only someone outside your conditions can tell the difference.

People can witness the same events happening at different speeds. Einstein claimed that events that appear simultaneous to a person in motion may not look simultaneous to someone who is standing still. So reality may actually be a mess of people walking around in slightly different timelines that sometimes synch up or intersect, depending on their conditions.

Last, but not least. One day, time itself must die. So how long have we got? In four out of five possible calculated scenarios, time is most likely to end in about 3.3 to 3.7 billion years. In the fifth scenario, time could end before you finish this sentence.

So it turns out we live in a reality that's like an old pocket watch, and one day it's just going to wind down. In fact, when it happens, we won't even see it coming. The scientists describe it like watching someone falling into the event horizon of a black hole. Things slow down and eventually just ... stop.

We won't even be aware of what's happened. Everything will work one second and won't the next. We'll all just be frozen in place, completely still. Forever and ever.

Prologos, I was addressing givemejustalittlemoretime, not you. Sorry

prologos

looking at the writings of Krauss and company, it is apparent that time existed -- even before the universe we live in, because

if the present setup came out of the instability, the fluctuations of the pre-big bang cosmic void,

time was needed even time to the second power,-- to have movements,-- like fluctuations that are really ACCELERATIONS present.

it is a small step from that, to realize that time existed a long time before us and will into the future, all the way to an endless eternity.

how do we know that the light, it's message from the distant past does not lie? at that speed time is at zero, there is no time to think up a lie.

that's why.

C.O. I am defending my innocense, even if not guilty.

Is there such a thing as time? ys there is and we are granted a small slice,

make good use of it. it might turn out nice.

Time is distorted by forces such as gravity. This results in time changing speed as one moves further from the earth's surface. For this reason, the times on the satellites used for GPS have to be kept updated to compensate.

Space is likewise not linear, but is distorted along with time by forces, such as is exerted by bodies such as the sun and by "dark matter".

Although the late iron age people who penned the Hebrew myths said that the earth hangs on nothing, it is indeed held in place by the interplay of these forces.

givemealittlemoretime I guess when we study time it becomes a thing (re your thread title). Then it loses its dynamic qualities too. Same goes for space prologos. Madgiant and Doug I think I'd tend to agree with you guys about how complicated time and space are. can we have one without the other in real life?
