pound. Some of you might think that it should come out to a total of ten
hundred atom bombs per pound -- five hundred gravitational and five hundred
electrical. No, it's only five hundred atom bombs per pound because winding
it up one way is exactly the same thing as winding it up the other way.
Coins have two sides, heads and tails. You cannot make coins with only one
side. For every heads there is a tails. Plus and minus charges are like
heads and tails. Space and time are like heads and tails. And electricity
and gravity are like heads and tails. You cannot space things away from each
other in the gravitational field without making them small in the electrical
field. I think that we're ready now to attack the consequences of this new
understanding of physics. We want to find out whether, through this
understanding, we can trace our physics all the way back to square one, to
see whether, underlying it, there may be something akin to magic. We want to
know why things fall. We want the answers to our why questions.
I'm going to draw you a quick map. This is a picture of the physics
before Einstein: Mass Space
Energy Time In the last century we thought that mass was one thing;
energy was another. Space was one thing; time was another. In our present
understanding of physics that won't work. Space and time are just two sides
of the same coin. Mass and energy are just two sides of the same coin. And
there is no line through there:
Mass
Energy
Space
Time
There is no line between mass and energy or between space and time. And
we just talked about the way in which the universe is wound up in order to
make the particles massive. They're wound up against space. They're spaced
in against the electrical field, and they're spaced out against the
gravitational field, which means that what we call matter and energy are
also nothing but geometry, and the line down the middle goes too. But when
the lines go, the picture goes. When the lines of demarcation between mass
and energy and space and time are obliterated, we do not have a model of a
physical universe. Every definition in our physics, every concept in our
physics. requires measurements of length. or of Einstein's Physics Of

time, or of mass one or more of these measurements. And without the
discrimination between length, time and mass we have no way to measure
anything in physics, no way to define anything in physics. Our model of the
universe does not hold up when we examine it from the standpoint of
Einstein's equations. And what we are left with I shall indicate here by a
question mark: ?
What is it that exists behind our physics? Relativity theory does not
say exactly what it is, and our task is to find it out, if we can.
First let us understand a little bit about what we call causation in
physics. What do we mean in our physics when we say that one thing causes
another? We mean that there is a transformation of energy from one form to
