That seems to be the reality of the moment. It was you that noted imprecision in the use of Universe by someone else. I merely pointed out your imprecision. The fact remains I cannot get to Proxima Centauri by any existing means. That is an irrefutable fact. Now if you wish to let someone state "If the universe is all that exists" without comment, I can allow ""Universe" as defined in BB cosmology translates to something more like "all that you can geometrically travel to"" without comment.
You have not. The key word remains "geometrically", meaning "as far as is permitted by geometry". Travel to Proxima Centauri may be economically forbidden, but it is not geometrically forbidden.
The fact remains I cannot get to Proxima Centauri by any existing means. That is an irrefutable fact.
I do refute it. An Energiya booster is physically capable of hurling your person fast enough to escape the solar system, and it is commercially available. There may even be enough energy for you to have a space suit. If pointed in the right direction, you may after many millenia pass as close by Proxima Centauri as you like--forsooth, even plunge into its chromosphere.
