When did the Big Bang stop being a theory? Did the Doctor bring us back footage of the event? If he didn’t, then what basis do we have (in fact) for the following:
Astronomers using the Hubble Space Telescope have discovered the oldest known spiral galaxy, a 10.7-billion-year-old anomaly that by all rights shouldn’t exist. The galaxy was present in the early universe, about 3 billion years after the Big Bang, at a time when galaxies were still forming and normally looked clumpy and irregular. “The vast majority of old galaxies look like train wrecks,” said UCLA astronomer Alice E. Shapley, one of the discoverers of the unusual spiral galaxy. “Our first thought was, why is this one so different, and so beautiful?” [emphasis added]
Perhaps it is different and beautiful because it was made that way.
“The fact that this galaxy exists is astounding,” [David R.] Law said. “Current wisdom holds that such grand design spiral galaxies didn’t exist at such an early time in the history of the universe.”
Perhaps the current wisdom is wrong. After all, such a thing has happened a time or two in the history of humanity.
