We can measure the expansion of space via the galactic redshifting.
Please for now excuse my order of mag. estimate, but in mks units, Hubble's constant is roughly:
[tex]H=2\times 10^{-18} {\rm m/s/m}[/tex]
If this exapansion was much larger. Say [tex]H'=2\times 10^{-10} {\rm m/s/m}[/tex]
Could a 'table-top' device with impeccable sensitivity measure the expansion of space.
I'm not an experimentalist, but perhaps using lasers, interferometers perhaps??
Any thoughts on how this could be done, or if it is fundamentally possible...
Thanks in advance.
