But interestingly the "space warp technology" some physicists

Warp drive uses the same part of General Rel that allowed the
universe to expand to ~100 bn LY diameter in 13 bn y.
These concepts are science fiction with no comprehensive basis in
fact and certainly never demonstrated or obserned in any way.
There always has to be at least one "nay-sayer"??

casagiannoni (various nyms)says the universe has not been observed in
any way and probably does not exist.
Who is to say just this one time he didn't guess wrong?

The radius of the observable universe is therefore estimated to be about
46.5 billion light-years and its diameter about 28.5 gigaparsecs (93 billion
light-years, or 8.8?1026 metres or 2.89?1027 feet), which equals 880
yottametres.
Age: 13.799?0.021 billion years
Diameter: 8.8?1026 m or 880 Ym (28.5 Gpc or ...
Density (of total energy): 9.9?10-27 kg/m3 ...
