is light really the fastest phenomena in the universe???

[NeutrinoWave]

Yes, because it's relative. However, it would mean the universal speed limit is doubled, no?

PS - Did a certain Mr Pratchett not once postulate that the unit of inheritance was faster than light? If the King dies on one side of the planet, and his son is on the other, light would take (allowing for the corner) maybe half a second. And yet, at the instant of the King's death, the son is King - the inheritance particle, and thus the Kingly mantle, having translated instantly across the intervening distance.

For your Inheritance principle this has a dependency on information being conveyed from A to B, before Inheritance can take effect at B.

Whether the Information is carried by light or a gravitational wave, information travel itself will not be able to exceed the speed of light, unless the information is carried on the boundary of the expanding universe.

There was talk that the period of inflation was faster than the speed of light, but I do not currently have a quantifiable measure as of yet of the Speed of Inflation, but you may have started a new thread.

The hypothesised speed of inflation is far faster than the speed of light. Its OK though, as that's space stretching, not stuff moving. Space can stretch faster than stuff can move across it without violating GR.
