Many other questions are on my RG pages for example:

- Is the terrestrial mile(1.609344 km) the wavelength moving at speed of light of a possible vibration of all space possibly created since the big bang?

- What allows the photons that emerged since the big bang to continue traveling at speed, c, until today? On this base what is the radius till now?

- What is the role of the gravitational waves and of their energies in free space?

- Once launched at the speed, c, by an antenna for example, are the photons taken in charge by the vibration of space to continue traveling at c?

- To travel at speed c, must the photon ride the waves of the vibration of space?

- Is the terrestrial mile (1.609344 km) the wavelength of the vibration of the space?
