another. For instance, if the hydrogen falls together to galaxies and stars,
the gravitational energy is first converted to kinetic energy in the
falling; and then the kinetic energy is converted to radiation when the
hydrogen falls together into stars. When radiation from stars like our sun
is picked up by all these green leafy things which we call plants and trees,
it's converted to electrical and magnetic forms. So all these things happen
by changes in energy, by changes in the form of the energy. The amount of
energy does not change. There is no such animal as the generation of energy.
The amount of energy, whatever it is, seems to be completely unchangeable.
It's one of our most basic observations in physics. And what we mean by
causation is changes in the form of this energy. Matter itself is energy,
and what we mean is that when something happens, whether it's hydrogen being
converted to helium, or whatever it is, there's some change in the form of
the energy. Now the universe cannot arise by this kind of causation simply
because in any such change the amount of energy at the end is never any
greater than the amount at the start. You cannot manufacture gold by
remolding gold. You never finish with more than you started with.
With this understanding of causation in mind, I want to go back to our
question mark. We want to see whether we can get some idea of the nature of
what the equations of relativity theory say must exist behind the universe
of our observations. And we want to see how, from that nature, we come to
the world of our perception.
When we look at this question mark, what we see is that it has to be
beyond space and time. Our physics is on our side of space and time, if you
like, but Einstein's equations say that behind our physics there is this
question, "What is it?". We know that it has to be beyond space and time.
And for that reason we can get a negative statement about what it is. If
it's beyond time, it must be changeless, because only in time could we have
change. If it's beyond space, it must be both undivided and infinite,
because only within space could we have things finite and divided. Without
space you couldn't break a. cookie in two. Without space you couldn't have
cookie crumbs. And without time you couldn't do anything, because you
couldn't have any kind of change. So whatever exists behind this universe
must be changeless, infinite and undivided:

The curious thing is this, that what we see is apparently not
changeless, not undivided and not infinite. It is obviously finite. The
teeny-weeny particles that make up the hydrogen atoms and all the rest of
these atoms and molecules are really minuscule. The number of hydrogen atoms
required to make a single drop of water is equal to the number of drops of
water in a million cubic miles of ocean. They are certainly finite. And this
matter is divided up into atoms. Why should it be so divided? And it's
continually changing. You can look anywhere. So what we see is changing,
