How Relative Is Time?

hello,

was thinking about the nature of time since the big bang and was interested in your thoughts on if its been constant leading up to our present day?

"The mind creates a mental reference frame so that it can try to keep a handle on things, however, our concious observation of the passage of time shows that it seems to be a local phenomena due to the warped fabric of speed."-PJParent (circa 2007)

In my theory of time it has been accelerating since the "Big Bang" but at a constant acceleration. This accounts for the accelerating expansion of the universe and gravity.

The measurement of time is individual and though constant to the individual not between individuals.

Well said. That is a good way to explain it.

I'm really not too sure about the big bang theory. It seems nuts to me to think everything in the known and observable universe came from one single big bang. I've believed since the age of ten the universe goes on forever. If you were to reach the far shores of the unverse you would then need to ask what lies beyond it. The size of the known universe gets bigger every time the astronomists get a bigger telescope. It was amazing to see those deep space Hubble Telescope images. It confirmed my theory. More star stuff! Yey!

What does THAT mean?

@all
Let's say we pick a time some time shortly after the big bang when Cesium exists. Lets say we shine light on it and measure the absorption frequency. From that we develop a time base.

Now, let's say all time in the universe is measured relative to that Cesium absorption frequency, and the relationships never change. Everything behaves consistent with respect to the cesium. And, cesium is consistent with cesium all over the universe. With all that in mind, the concept of time "changing" is meaningless since there is no reference to compare it to.

Now, let's say that time passes at different rates in different parts of the universe. Wouldn't we see that in the emissions of stars?

It looks to me that time is probably constant across the universe (within relativity) and probably has not changed.

I don't think there is some non-linear process that would allow us to detect some sort of "true time". But then, even if we could, who is really true? Our time, or its time.

As for the subjective individual human experience, that is notoriously unreliable in a physics sense (by cesium absorption standards) but significant to the individual.

But does it make a practical difference to a certain cat? If his box is going too fast to catch, he's immortal, right?

I have thought the same. That is why I put the quotation marks on "Big Bang".

I think we observe an "Expanding Universe" because gravity gives us a distorted perspective of time.

The idea that the universe goes on forever is becoming less popular but when we are able to see even further out and still see the same stuff maybe the idea will make a comeback.

I believe gravity is a effect either caused by the acceleration of mass through time or the acceleration of time through mass. i think which one is a matter of perspective.

I believe this effect can also be simulated by acceleration of mass through space.

I believe that the attractive properties of gravity can effect the speed of time.

I believe this effect can also be simulated by the attractive properties of electromagnetism.

I believe that time and gravity are combined each being the cause and effect of the other.

I just have to say nonsense. Sorry, but this makes no sense to me.

For example, what IS the acceleration of mass through time and how is it different than mass not accelerationg through time. How can gravity exist around mass that is just sitting there? How is just sitting there "accelerating through time". If just sitting there is "accelerating through time", then what is "constant velocity through time".

believe what you want, but at least try to make sense.

My point is it can't

I think it would be at or close to the speed of light.


My concept of gravity and time does make sense to me.

What does not make sense to me is the idea of some sort of graviton particles creating gravity or any other EM force.

gravity is the result of acceleration. There has to be a medium for acceleration. Space is three dimensional movement no room for the acceleration required for gravity. Time is a separate dimension with the properties of multidirectional linear movement giving the medium for acceleration.

The movement of linear time created the gravity well and the distortion of time and space.

speed = space / time

some prefer the term Velocity

so now we get GravitySpaceTimeVelocity, or GSTV or:

4! = 24

GSTV
GSVT
GTSV
GTVS
GVST
GVTS
SGTV
SGVT
STGV
STVG
SVGT
SVTG
TGSV
TGVS
TSGV
TSVG
TVGS
TVSG
VGST
VGTS
VSGT
VSTG
VTGS
VTSG



so now we can perhaps add Mass, Energy... which leads to one conclusion that it is all inherently due to the GravitySpaceMassTimeEnergyVelocity base ten raised to the power of zero or a multiple of three.

the nature of time is duration of events
being measured or not
universe expand in space only and not into time
time is duration of expanding into space

this is a great insight
why you have to find out yourself

stronger is gravity slower is the speed of events and longer is duration of events
closer to the sun you will get older slower
but not in time, in space only
we are living in space
and duration of our liefs is time
this is how time is relative

The universe is not expanding from a single point in space but from a single point in time.

There is no spacial center from which the universe is expanding from.

The point of origin is in time not space.

Observational evidence shows this.

Space is only a three dimensional framework in which everything has a coordinate at a certain place in time.

Space has no motion only time does.

I have found that when I revisit a favorite place, it is just never the same as it was when I last left it. It just seems so different since everything changes over time.
