Caedes, Viviane, of course it is understood that the earliest galaxies or what emerged from the obscurity is now further away then when they emitted their light but
to use the HORIZON on the curved earth surface and 'curved' space as an analogy, the horizon is as far you can see, or as far as back in time we can see.
that is why, according to some, the Universe is thought to be 'NOW' more like 45 billion light years across . the most part BEYOND our horizon, like my house roof gives me a 37 km water horizon, that is where the sun sets, but I know the whole earth stretches all the way back to where it will come up. enjoy the 230 degree view.
It is very entertaining and a good learning tool to push your choice of words to the limit, within the confines of understood scientific facts. like
saying "You and I WERE in the big bang", our energy, coming matter were. and so were the galaxies whose light now reaches us from within the 'lightcone' visible to us.
pushing the language limit might push some to the limit, but by trying to REFUTE error, rather then word choice, we all learn.
to learn, that is way enjoy reading here, if it is not pushing the limit, I learn nothing new.
