Our universe was created by a collosal explosion of matter 13 billion years ago called the big bang. In that time, this matter has expanded to a width of over 1666000 light years.

It is only as big as it has to be to contain the matter within. Anything beyond that matter doesnt exist because it doesnt have to. And as long as matter keeps expanding outwards, the universe will continue to grow with it, so that boundary of the universe will never be reached. So technically its finite, but naturally infinite.

This is one with which I can agree - no argument.
