EXCERPTS:

In 1884,
a world conference decided that the Meridian Line
that passes through the observatory at Greenwich
was to be the initial meridian -- the master time for planet Earth.
Greenwich Mean Time is our best approximation of time
as described by Sir Isaac Newton.

Newton believed the Universe was like a giant clock
set into motion by God.
But Newton got it wrong.

Newton's concept of time was that IT WAS ABSOLUTE.
... the problem with this is that it's actually impossible
for any of us to detect absolute time.
We don't detect absolute time.

We detect time as relationships between things that happen.

This was the great insight of Einstein, and it was the basis of his general Theory of Relativity --
that time is created by the relationships of the changes that happen in the Universe,
and nothing else.


Freeman: Even today some people have a hard time accepting
Albert Einstein's relational time
over Isaac Newton's absolute time.
But the better we get at telling time,
the more we can see that Einstein was right.


This is the aluminum ion experimental clock
at the National Institute of Standards and Technology
in Boulder, Colorado, America's official timekeepers.
It's the world's most accurate clock,
measuring the oscillations of supercooled atoms.
It keeps time to withing one second every 3.7 billion years.

In 2010, Bouler's time lords
took two ion clocks side by side
in perfect synchronization,
then moved one of the clocks up 12 inches.
THE HIGHER CLOCK WENT OUT OF SYNC.
IT BEAT JUST A TINY BIT FASTER THAN THE LOWER CLOCK,
because the higher clock is just a tiny bit farther away
from the gravitation pull of the Earth,
which slows things down.


Einstein
Space-Time, Four Dimensions
(further).. that gravity is a manifestation of the curvature of space-time.

relativity of time: such as time running faster for astronauts
than people on Earth.


The older we get,
the faster the currents of time seem to carry us along.
Our relationship to time changes as we age.

Studies show that the passage of time
seems to increase by the square root of your age.
So, if at 10 year old, it's 1:1,
when you're 20, it's 1:1.4.
And by the time you're 60, it's 1:2.44,
about 2 1/2 times faster.


Freeman: It takes a few millionths of second
for your brain to put together information
and serve it up to your consciousness,
which means that we're all living a tiny bit in the past.
This time delay is the tradeoff our brains make
to give us the best story of what happened.


Your Personal Time:
This man perceived the world as having accelerated.
in reality, he had slowed down.
He walked and talked in slow motion.
He had become unstuck in time.
It turned out that his time sickness
was caused by a brain tumor.
[Time Sickness / Schizophrenia]


Whatever time is,
it's deeply wired into us.
We are all clocks with our own internal time.


Time is Illusion:
Declaring that time is an illusin
may sound radical,
but the denial of time is an old idea --
2500 years old.

In 500 BC the philosopher Parmenides
declared that motion is impossible
because for an object to move any distance,
it would have to pass through an infinite series
of fractional steps to get from one place to another,
and no one can take infinite steps.
And if motion is impossible, then change is also impossible.
So, therefore, time must be an illusion.


Freeman: Our brains assemble these frozen moments
and play them in our minds
the same way that still photographs
played at 24 frames per second
make the images you're watching now seem to move.
But nothing is moving.
What we call "time" is an illusion.

Barbour: In some very deep sense,
the Universe, the quantum universe,
is just static.
Nothing changes.
   
Freeman: And according to Julina (Barbour) all of these snapshots of the Universe
exist simultaneously.
If i were to say that my yesterday no longer exists,
it would be like the number 13 saying that 11 has died.

This moment is eternal.


Julian Barbour believes space is all there is and time is an illusion.
Tim says Julian has got it all wrong.
We need time, but we don't need space.

Freeman: Did space come first...
Or did time come first?

Lee Smolin believe that time is older than the Universe --
it was here before the Big Bang,
and it will be here after the Universe ends.
[is time god?! asks abro]
And he thinks he can prove it by looking closely at how particles of light behave
over long distances.


... that light travels at 186,282 miles per second.
if time is an illusion, then this ill be true everywhere in the Universe,
no matter where we look.
But if time is real,
it's possible that the laws of physcis have changed
as the Universe has aged.

... physics has evolved since the Universe was born,
so time can't be an illusion.

... may be the speed of light is NOT Universal.

The Fermi Space Telescope is one such experiment.


ENTROPY:
[arrow of time]

As time goes on in the Universe as a whole,
disorderliness, entropy goes up.

Since the explosive birth of the Universe,
the increase of entropy is the reason
why the pas is different from the future.
