questions.
What I want to talk about next is a discovery made by Albert Einstein
when he was 26 years old and working in the patent office in Bern. Then I
want to talk about the" consequences of that discovery and, through that, I
want to trace our physics back, if possible, to answer those why questions.
Einstein noticed that we cannot have an objective universe in three
dimensions. We all talk about 3-D. Hardly anybody talks about 4-D. But the
universe is 4-D. It is not possible to have a universe of space without a
universe of time. It is not possible to have space without time, or time
without space, because space and time are opposites. I don't know that
Einstein ever used the language that space and time are opposites, but if
you look at his equations, it is very, very clear that that's exactly what
they are. If, between two events, the space separation between them is the
same as the time separation between them, then the total separation between
them is zero. That's what we mean by opposites in this case. In electricity
if we have the same amount of plus charges as we have of minus charges, say

atom or the same molecule, then that atom or that molecule is
neutral. There is no charge seen from outside. Likewise here. If the space
separation between, two events is just the same as the time separation
between those two events, then the total separation between those two events
is zero. I'll give you an example. Suppose we see an exploding star, say in
the Andromeda galaxy. There's one going on there right now. It's been
visible for about a month or so. Now the Andromeda galaxy is two and a
quarter million light years away, and when we see the explosion now, we see
it as it was two and a quarter million years ago. You see, the space
separation and the time separation are the same, which means that the total
separation between you and what you see is zero. The total separation, the
real separation, the objective separation, that is, the separation as seen
by anybody, between the event which you see and the event of your seeing it
-- the separation between those two events is always zero. What we mean when
we say that the space and time separations between two events are equal is
that light could get from one of those events to the other in vacuum.
We see things out there, and we think they're really out there. But,
you see, we cannot see them when they happen. We can't see anything when it
happens. We see everything in the past. We see everything a little while
ago, and always in such a way that the while ago just balances the distance
away, and the separation between the perceiver and the perceived remains
always at zero.
As soon as Einstein noticed that we cannot have a universe of space
without a universe of time and vice versa, and that they are connected in
this way, and that the only way to have an objective universe is in four
dimensions, and not in two or three or one -- as soon as he noticed that, he
had to redo our physics. Now relativity theory is a geometry theory. It's
not something else. It's a geometry theory. It's about the geometry of the
real world. I'm sure that most if not all of you have been exposed,
somewhere along your educational careers, to the geometry of Euclid. His
