I thought it was already understood that neutrinos and other sub-atomic particles can travel faster than light.
AFAIK, the speed of light speed limit, only applies to atoms.
That's why, right after the big bang, the universe expanded faster than the speed of light (cosmic inflation), because atoms hadn't formed yet.
The universe is 13.7 B years old, but it is far more than 27.4 B light years across. That means it had to travel at much faster than the speed of light for quite some time.
