From July but interesting. Is our universe older than we think?

Or doesn't have our universe an age at all?

Time doesn't exist for light, why should it then for our universe?

Time does exit for light to travel from one point to another hence light year.

For us yes, but travelling with the speed of light means no time lapse for the traveller.

Yes a photon experiences no time. From it's frame of reference it was an instantaneous flash and the universe was two dimensional.
