The universe should not be infinite. (Adams&Co with no name hand)

A must-be-infinite feeling may be caused by the supposition that in imagination we could proceed in space boundlessly, I don't know anything why and when to stop.
The space should not be warped.
You might prove Hubble's acceleration should be replaced by proportion-to-distance dispersion in your laboratory. The universe does not have it's life history like human beings'.
The flat limited ageless universe we can believe in.
