If the age of the universe is somewhere around 15 billions years, how can it be 78 billion light years large? Time distortion? If so, is the universe much older relative to an object that isn't travelling outward as fast as we are?

I'm not sure, but I think it's because of how fast everything expanded immediately after the big bang.

Perhaps the problem is that you are assuming the narrator is correct.

Perhaps, but I think it's an established fact the universe is larger (in terms of light years), than it is old.

Of course, if you assume a perfectly spherical universe with the big bang happening at its center, and the universe expanding at the speed of light, being 15 billion years old, it would be 30 billion light years across.

Of course it can't be that uniform.

the speed at which the universe expands is also always increasing. also leading theories suggest that the universe is perfectly uniform.
