Clearly defined and make sense.

And unaffected by getting close to the edge of the picture.

Whereas the sizes are changed.

So conformal geometry is the geometry of angles, if you like.

In uh space time it's the geometry of the light cones.

So you have the null cones, I should say.

The Null Cone.

Gives you

Nine out of ten components of the metric.

The tenth component really is the example.

The uh

Scaling of the whole thing?

And that is is given by the mass.

The scaling of the mass comes from the two most famous formulae of twentieth century physics.

One of them is E equals M C squared, and the other is E equals H new H F if you like, due to Planck.

So the Einstein E equals Z M C squared and the Max Planck

Equals H F or H new.

Put the two together and that tells you that

Uh frequency.

You see the energy is one and energy is the other.
