:17:01
is it's totally a fantasy created by
mad physicists trying to figure out...
:17:06
what the heck is goin' on
when they do these little experiments.
:17:10
By little experiments, I mean big energy
in little spaces in little pieces of time.
:17:15
It gets pretty nutty
at that realm of things...
:17:17
and so subatomic physics was invented
to try to figure that all out.
:17:22
We need a new science down there,
and it's called quantum physics...
:17:25
and it is subject to a whole
range of debatable hypotheses...
:17:31
thoughts, feelings, intuitions
as to what the heck is really going on.
:17:36
Matter is not what we have
long thought it to be.
:17:39
Uh-- To the scientists, matter has always
been thought of as sort of the ultimate...
:17:45
in that which is static
and predictable.
:17:49
Within all the atoms and molecules,
all the space within them...
:17:54
the particles take up
an insignificant amount of the--
:17:58
of the volume of an atom or molecule,
the fundamental particles.
:18:02
The rest of it is vacuum.
:18:04
What seems to happen is that particles
appear and disappear all the time.
:18:07
So where do they go
when they're not here?
:18:10
Now, that question is tricky.
:18:13
I'm gonna give you two answers--
Answer number one:
:18:17
They go into
an alternative universe...
:18:20
where the people in that universe
are asking the same question...
:18:23
about those particles when
they come into our universe.
:18:26
They say, ''Where do they go?''
[ Chuckles ]
:18:31
[ Man ] There's a great mystery called
the mystery of the direction of time.
:18:36
There's a certain sense in which the
fundamental laws of physics that we have...
:18:39
don't make any interesting distinctions,
say, between past and future.
:18:43
Um, for example, it's a puzzle from the standpoint
of the fundamental laws of physics...
:18:49
why we should be able to...
:18:52
um, remember the past, um...
:18:55
and not have the same kind
of epistemic access to the future.
:18:59
It's a puzzle from the standpoint
of these laws...
