Well, infinity absolutely would contain everything - there would be Adam's planet that grows Phillips screwdrivers, which is of course absurd but infinity so... universe isn't infinite tho

I don't kno why ppl believe that it is. It's very big, we have no frame of reference bc it literally contains all possible known frames of reference and even with that in mind, we need a bigger thing to grasp how big it is, we won't ever have that perspective.

That doesn't make the universe infinite tho. Even if the universe is expanding at a rate greater than we could ever catch the other galaxies and this expansion limitlessly expands the universe, THAT is still not infinite.

There is no infinite thing bc nothing is infinite for real, it's an idea
