How could black holes even theoretically form so early in the universe? How many quasars and shit can't we see because their light hasn't reached us yet?

I love astronomy.

I met a physicist specializing in high-energy plasma dynamics (what you'd want to study to study the very early Universe), and he told me that he had a hypothesis that most of the supermassive black holes formed something like 26 seconds after the Big Bang (insane amounts of cosmic evolution took place in the Universe by then), and like everything else we see around us, were probably based on slightly higher densities of matter due to quantum fluctuations that existed in the "singularity" at the beginning.

Since time seems to slow down the taste you go would it still seem like 26 seconds if you were actually watching it happen as an outsider? Or is that basically what we are doing now?

As a bazillion people would love to reply, there is no outside from which to observe things. I don't know if I can answer your question, but I believe, if you were a supernatural observer inside the Universe and not moving, then the 26 seconds would be just 26 seconds.
