Lines on the graph a vertical line is the radius of the universe which is moving to the right at the speed of light.

Lines on log-log plots represent equations. The line at the tops shows where an object turns into a black hole. The radius of a black hole is proportional to its mass.

The line at the bottom shows the wavelength of a particle. The wavelength has a negative slope which means that the wavelength is inversely proportional to the mass.

Some particles have zero rest mass (the photon)
some have unknown mass, the graviton,
some have no radius, the electron.

Time and space are related by the speed of light in a vacuum. Looking out in space is looking back in time.
