Or we just got the dark ages wrong
This is really a problem of the "dark ages" - roughly, red shifts between 1400 and 14 (i.e., the period between just after the cosmic microwave background up to the earliest quasars and galaxies). At one end, there are no black holes, at the other, there are supermassive ones, what happens in between, we don't really know. My own personal guess is that this is a consequence of dark matter, and thus wouldn't require worm-holes but, if we can test the wormhole hypothesis, we should. We know so little about the dark ages that IMHO no possibility should be ignored.

Re:C strings strike again!
Pitty intel didnt implement string functions in the CPU.
They did. Welcome to decades ago.

The biotechnology is at least quite believable
Even if their neural interfaces are a bit out there. We've been growing humanized mice for years. I wonder if all they really needed to do, however, was to generate a chimera by seeding an embryo with a human nervous system before the immune system starts to develop. We've learned quite a bit about developmental biology from avian chimeras, mammalian chimeras are a bit more challenging but can be achieved.

China block English Wikipedia
You won't be able to access the English Wikipedia site from China. This is disgraceful. I can't imagine any party or leadership would block information flow as the communist does. China is so corrupted that people in China would not know how to live if the country suddenly becomes a country of freedom. So, don't be suprised by the difference. Guess what? If they don't differ, there won't exist Chinese Wikipedia either... Peking University, one of the best higher institutions, won't allow students to surf any websites not hosted within China unless specially authorized. Suprised?

Re:Geek explanation required.

The problem with your reasoning is that high magnetic fields (and, yes, this is one reason that perfectly spherical -- without net angular momentum -- black holes are basically impossible) really screw up the 13.6eV ionization energy for atomic hydrogen. In fact, strong enough magnetic fields (and you easily get them near black holes) raise the ionization energy of atomic hydrogen well into the thermal x-ray range. -
Re:HMO?Hmm... what about Beijing vs Peking? Two different cities, or a name change?
Same place, different pronunciation. In Cantonese it's "Pak-geng", many Chinese words adopted into English come from Cantonese rather than Mandarin (typhoon, ketchup, for instance). It's amused me how using a name like "Peking" somehow labels one as a colonial imperialist. However, "China" of course is not what the country is called, it's "Chung Guo". (The Ch'ins were an ancient dynasty.) China doesn't seem to care about that. But no one tries to insist the Chinese use native pronunciations for Western cities or countries -- their words for foreign places are far removed from what they're called by the inhabitants. It's all lacking in any consistency.
A lot of related words remain, though. Peking Duck; and Peking University is the offical name of the institution.

Pi: Not Random - Omega: Random (sort of)
Pi is not random, because there is an algorithm that computes its digits. It only "seems" like random.
Omega is a number that is well defined and has a value, but we are unable to compute it.
Omega is not random. It's a constant. But If someone (God?) gives us the value of Omega and the value of any random number, and we have to choose wich one is Omega, we have no logical way to decide.
