You answered your own question to a degree ... on one hand you accept that a rainbow is an illussion yet for some reason you feel certain that infinity is not.

Can I ask why?

Take human experience.

- Originally the universe was a flat earth
- In the 1500's we progressed to earth centre of universe and sun and moon circling it.
- Progressively we realized there was more bodies and our universe grew.
- By 1900's and Einstein we had progressed to the known universe as you would refer to it.

QM is simply telling us the universe is even bigger and more complex than that, if by the universe you mean the term to encompass all known things.

Is that the end of the line? ... it might not be we can not know at this point in time there may be something beyond that.

My problem with your conjecture is we can not even clearly define the universe and you worry about is it infinite or not ... to me thats a bit strange.

I believe in "Evil, Bad, Ungodly fantasy science and maths", so I am undoubtedly wrong to you.
