Of course there is empirical evidence. Any object that has a cosmological redshift z> 1.46 has a recessional velocity greater than c.
The reason we see some of the photons emitted was explained in my previous post.
Objects formed in this era occurred at a time before there was an acceleration in the expansion of the Universe. Photons that are intially superluminal become subluminal as the velocity of the Hubble sphere can eventually exceed the scale velocity of the Universe. These subluminal photons become observable.The objects themselves however continue to recede at superluminal velocities.

For a more technical explanation.

The Wikipedia article regarding the speed of light refers to objects travelling in space-time. When we refer to recessional velocities of objects, the objects are in fact stationary in space-time but are being carried by the Hubble flow or the expansion of space-time.

The Wikipedia article has no relevance.
Thanks for exposing what is wrong with your concept of the universe
