'Time and Indeterminacy vs. Continuity'

What is time?

Dictionary.com/time:
'Time is a nonspatial continuum in which events occur in apparently irreversible succession from the past through the present to the future. An interval separating two points on this continuum; A similar number representing a specific point on this continuum, reckoned in hours and minutes: checked her watch and recorded the time, 6:17 A.M.'

Question : What is time?

Officially 9,192,631,770 beats of a cesium atom is 1 second. Time is what we measure with clocks, one tick, one second, at a time.

What do we know?
A quote from Paul Davies book:
'About Time':
'At the speed of light itself, time stands still'. (page 190)

We know that time can stand still.

Another quote from Paul Davies book
'About Time':
'In quantum physics, energy always goes hand in hand with time. In a sense, the amount of energy determines the rate at which time passes - the beat of the atomic clock if you like. No energy means the quantum clock ceases to tick: time bafflingly drops out of the physical description altogether.'
(Page 180)

Energy is the capacity of a physical system to do work. And work is the transfer of energy from one physical system to another. There can be no work, therefore no time, without the potential for the transfer of energy. And a total energy-less void would be timeless.

The forms of energy include: heat, light, sound, electricity, and chemical energy.

Some Mental pictures:
A photon Traveling at c; sound Traveling from a stereo speaker to the listener's ear; electricity Traveling through wires to light a desk lamp.

Dictionary.com/travel:

1) To go from one place to another, as on a trip; journey.
2) To go from place to place as a salesperson or agent.
3) To be transmitted, as light or sound; move or pass.

Travel means to be transmitted, as light or sound, move or pass.... move,... movement,.. ..motion.

All energy is always in motion.
In fact, everything from galaxies and people to quarks and electrons are always in motion.

Motion is the act or process of changing position or place. And there can be no motion without energy. The amount of energy determines the amount of motion, and as Davies said: 'energy determines the rate at which time passes'. Since energy determines the rate at which time passes, energy cannot be time. And it is energy which causes the act or process of changing position or place which we call motion.

What happens if we stop all motion?
We know that all motion stops at absolute zero, -460 degrees F.

Would time stop as well?
Here is the simplest equation, which included time, that I could find:
Velocity * Time = Distance

Step by step, what is velocity?
Velocity is rapidity or speed of motion; swiftness. A vector quantity whose magnitude is a body's speed and whose direction is the body's direction of motion. The rate of speed of action or occurrence. Velocity is the speed of motion.
Velocity is not motion.

What is speed?
Speed is the rate or a measure of the rate of motion, especially: Distance traveled divided by the time of travel. The limit of this quotient as the time of travel becomes vanishingly small; the first derivative of distance with respect to time. The magnitude of a velocity.

Again, just as Velocity is defined as the speed of motion; Speed is the rate of motion.
Speed is not motion.
Velocity is the speed of motion;
Speed is the rate of motion.

Velocity and speed are simply the measurement of something; motion.

Just as a temperature reading is a measurement of heat, the reading on an outdoor thermometer in the winter , of 32 degrees for example, is not the temperature itself. If you place your hand on the thermometer it may feel cold, but it is not the mercury, which gives the 32 degree reading, inside of the thermometer, which is making your hand cold. Move your hand away from the thermometer, and you will still feel the 32 degree temperature.

I'll skip over time, and ask:
What is distance?
Distance is the extent of space between two objects or places; an intervening space.
The fact or condition of being apart in space; remoteness. Mathematics. The length or numerical value of a straight line or curve. The extent of space between points on a measured course.

Going back to the equation:
V= velocity is the speed of motion.
D= Distance is the intervening space.
T= ?

Gedanken:
Racer X will use this equation to improve his time in the quarter mile.
He sits in his race car revving up his engine until the RPM Gauge hits its mark.
He knows that soon he'll be shot off at a tremendous speed.
He waits, the Go light signals red... then... yellow....then Green!

Nothing happens.
Why?
His RPM gauge showed he had more than enough Energy to bolt out of his standing position at a great Velocity, and the empty Distance was stretched out before him, with a wide open quarter mile of empty track ahead.
He knows that Velocity * Time = Distance
What went wrong?

There is not any motion in this equation -
he can't move.

*Either this equation is wrong or the 't' , the time, is motion itself.

Most people will say Velocity is a vector quantity whose magnitude is a body's speed and whose direction is the body's direction of motion.
Is the magnitude of something, the thing?
Is the direction of motion, the motion?

If time is motion this means that time continues, as long as the universe is in motion, then time will never stop.
Once all motion stops, time will, too.
Or said a different way, once all motion stops the clock stops ticking.

How can time be motion if an absence of any motion, -and- traveling at the maximum universal speed limit, the speed of light in a vacuum, both equal to a stopping of time?

The first part is easy enough to understand, time stops when all motion stops. Without motion, without any movement from point A to point B you cannot get anywhere and cannot figure out t in the above equation.

What about something like a photon which always travels at c? How can its time be stopped w/it moving at 300,000 kps?

Thats because - it cannot move.

At the speed of light time also stops, because all motion has stopped. Anything traveling at c cannot move at all, it is frozen,static in time. If it did make any movement, while traveling at c, that movement would then be traveling faster than c, and that is not allowed by the universal speed limit.

General Relativity teaches us that accelerated and gravitational reference frames are equivalent. And that clocks slow down in both.

We know from the Twins Paradox that one twin on Earth will experience Earth time at the expected rate of one second per second.
We also know that the other twin from the 'warp-drive' spaceship will return home to discover that more years have passed on Earth then have on board their spaceship.

This will be puzzling to our intrepid explorer because everything was normal on board.
The clocks ticked, people worked, they communicated and interacted in the usual way without any deviation.

How is this possible?
We know that the more mass or energy something has the more energy it takes to 'move it through time', or simply put, to move it. This includes everything, even energy, as the 'warp-drive' spaceship travels through space everything on it gains energy and slows down.
Everything on board slows down - all of the motion on board slows by the same factor, clocks tick slower, people move slower, electrons orbit slower, brain function is slower, thus no change is noticed.

Motion = time

Het wordt direct een seconde later op de maan. Dat wij dit pas na nog een seconde waarnemen, doet niets af van het feit dat de tijd op de maan synchroon loopt. Hetzelfde zou gelden voor een waarnemer op de maan.

In een futiele poging weer wat niveau in deze discussie te brengen, even deze filosofische overdenking: voor ons, op aarde, kan je indd zeggen dat de maan een seconde ofzo achterloopt op ons. Immers, niets kan sneller dan de lichtsnelheid, dus je kan ook niet spreken van een universeel 'nu'. 'Nu' is op z'n best het moment waarop wij iets kunnen waarnemen.

Dus als we naar een ster kijken die 10 lichtjaar weg staat, dan is wat we daarvan waarnemen feitelijk ons 'nu'. Met andere woorden: het begrip 'nu' hangt af van je persoonlijke locatie. En ja, Rude, dat geldt, strikt genomen, ook voor de groenteboer om de hoek.
