Size is a concept created in the human mind

Much like beginning and end

People don’t think the universe be like it is, but it do.

Big as fawk son.

size is essentially unknown as we're constrained by our light cone (i.e observable universe) and can't detect any curvature at that scale that would indicate it's a manifold.

So basically based on what we know, it either has a flat topology and is infinite (or it can be Taurus solution to the einstein field equations, in fact there's a string theory 'explanation' to a taurus toplogy that explains why we only see 4 dimensions despite string theory theorizing 11, it has to do with strings 'tieing' up dimensions but being able to 'untie' in 4 dimensions allowing them to expand, leaving 7 tiny dimensions that are small and compact that we can't see)... or it has a curved topology and is closed, but it's so huge that our instruments cannot detect the curvature over the size of our observable universe.

(havnt watched video)

The reality is, it's almost nonsensical to talk about the universe outside our observable universe because it is, by definition unobservable.
