Hi all.

My theory is that real, 'universal' time is invariant, I will describe the reasoning now with a thought experiment, and welcome comments. None of the equations of relativity are violated.

Before you dismiss this, for the first time ever recently I heard a respectable physicist allude to the same claim; it was the 'physics for future presidents' lectures on Google video.

Fact 1:

According to Einstein, time slows down the closer you are to mass.

This means, for example, that there exist 'time shells' around a planet.

This has been proved with atomic clocks: An atomic clock, at the top of

a high tower, runs faster than its originally-synchronized twin on

the ground. I accept this as totally true.

So most people say : proven by experiment: time can vary.

End of story? Not so.

Fact 2:

Relativity is based on something called the Lorentz equations. The basic

problem was this: The speed of light was found to be constant, irrespective of one's relative motion and frame of reference, by experiment. Now this at the time was a huge problem to physics because it broke the standard formula of speed = distance / time. One of the ways of bodging the equation so that speed can remain constant is to allow the measures of distance and time to vary.

However this is a purely mathematical construct. The idea of the measure of distance changing does not bother me at all, it is the idea that time can be treated so similarly to the other three dimensions. In my view it can't, although an EQUIVALENT EFFECT is caused by high speed or proximity to mass.

Now consider this diagram, it shows one-second snapshots of a man walking

along on a low-mass planet like the Earth :

O

-|-

/ \

------------------------------------------------------

1 sec

O

-|-

/ \

------------------------------------------------------

2 secs

O

-|-

/ \

------------------------------------------------------

3 secs

Now consider the result of the same man moving along over 3 seconds near a black hole :

O

-|-

/ \

-------------------------------------------------------

1.5 secs 2.25 secs 3 secs

- according to many physicists trying to explain these concepts in

laymans terms via the idea of 'time-shells,' the legs would be traveling

much slower in time, as they are nearest to the black hole, (read concentrated mass) the arms a bit faster as they are in the next time-shell up, and finally the head moving fastest in time, being the furthest away from the spacetime-curving effects of the black hole.

Of course, I am over-simplifying, the time-shell 'layers' would be

far more gradual, more finer, maybe even infinitely so.

However, can you see the problem? Near a black hole, the man is instantly

killed, because where his head is, three seconds into the future, he

has no arms or legs.

If time really does change , then this must be an accurate picture of what

would happen near a mass. But wait a minute - you don't need to be by a

black hole for GR to take effect! GR is in effect on the Earth - it has been

proven, as said, with atomic clocks mounted on towers clocking a faster time

than the ones on the ground. But hang on again - the observer on the ground

does not see the clock disappear from the top of the tower! The skeptic will

say (as one CERN scientist replied to me who didn't get my gist!) that we are

only talking about zillionths of picoseconds of difference, if that. Are we really going to notice that? The answer is - it doesn't matter, the argument is irrelevant:

If my head disappears off one picosecond into the future, then in the time-shell

of my body, I am dead! So the thought experiment is simple: If time really does vary in ways that it is understood to vary as per most people's interpretation of GR, *biological life could not exist.*

So what's the solution to this? As said, I am now very very happy that I have heard a senior scientist mention this, but basically, if an atomic clock at the bottom of a tower is showing a slower time, has time slowed down in the understanding, according to most physics layman's book writers, of : 'in a different time-shell?' My theory is - of course not - it is the *clock* that has slowed down!! And I don't mean via faulty clockwork!

Something must have happened, due to spacial dimensions changing but NOT time, that gives THE EQUIVALENT EFFECT of LOCAL TIME SLOWING DOWN for the object in question. I like to imagine a scenario whereby distance has increased in some extra spacial dimension that means that all atoms and subatomic particles and waves in my body and feet have, effectively, FURTHER TO TRAVEL in the same relative measure-of-distance that my head is experiencing.

What does this mean in practice? Basically this :

If time is infinitely granular, and I admit that I don't like this idea, then it means that my head is still attached to my body, but is a fraction of a zillionth of a picosecond out of *physical* alignment - my head has the orientation of its atoms in a state of motion one zillionth of a picosecond 'on' from where its alignment would have been had it been in the same time-shell as my body. But wait - surely even a small time difference would make a difference on planck scales? Scaling the idea up, would veins and bones and neural pathways get broken? Not so - because if my body passes through an *infinite* number of time-shells (read layers) then the 'physical misalignment' of my body as it passes through the so-called 'time shells' is *infinitely* smooth. Near a black hole however, I would be killed , as the misalignment would be so great between head and feet.

If I am right, what does this mean?

- there's nothing wrong with the Lorentz Equations as they stand. It is just

the *interpretation *of 'varying time' by most people that must be wrong.

- The special relativity idea of time slowing down for a high-speed object

is fine, as long as this is interpreted to mean 'CLOCK MEASURED TIME'

and not universal time . True, the concept in GR and SR is of course

frame-of-reference time relative to another observer. However I believe

that this frame-of-reference time must always be relative to a universal

time.

- The science-fiction idea of going back in time ( a concept openly thought

a possibility in the cutting edge of real-world quantum and theoretical

physics as well! ) is absolute nonsense. If such a 'local' effect is

possible, then that is equivalent to negative spacial dimensions in the

only-spacial-dimensions-are-allowed-to-vary way that I look at it, and

the idea of negative spacial dimensions (i.e. a size smaller than nothing!)

is just as absurd as negative time.

- A spaceship leaving Earth just under the speed of light carrying an atomic

clock would arrive on a distant planet at precisely the same real, universal

time (read universal time to mean that measured by a motionless clock near

no mass at the centre of the universe, the centre being the point of the

big bang) as that of an Earth-bound atomic clock. The spaceship's clock

of course indicates a date far in the PAST of the earth-bound observer,

and the astronauts are still, in real time, much younger than their aged

friends on Earth. This is caused by the spacially-slowed motion of their

constituent parts due to the high speed, giving the EFFECT of local time

having changed. In reality, they exist in the same moment, the same

'tick,' of universal time, it's just the clock of the astronaut is now

measuring the 'wrong' time (slow) when compared to our theoretical

clock-at-the-centre-of-the-universe. Our astronaut can travel back to

Earth, and true, he will meet and shake hands with his elderly Earth

friends, and the reason they can do this is that they exist in the same

moment of real universal time, and always have done !

In summary, my non-mathematical armchair theory is that some extra spacial dimensions have stretched, meaning all waves and particles have a LONGER PATH to travel through in space, giving the EFFECT of local time slowing down relative to a slower observer.

The Lorentz equations showing time in a reference frame as changeable MUST be simply a fortuitous mathematical equivalence to a more detailed, undiscovered equation that allows light speed to remain constant for two observers traveling in different frames of reference; one that would use maybe extra spacial dimensions to create the same effect.

My assertion here basically is that the idea of 'time-shells' is wrong, as

biological life could not exist, as per my thought experiment.

comments please!

p.s.

I can't remember it off the top of my head, but if anyone is interested, I will find and post the link to the Google video of the respected physics lecturer alluding to the same thing.
