This implies that the dilaton or heavy graviton mass and the radion unification mass must be greater than 5.1 meV and 7.1 TeV, respectively, and that the largest extra dimension must have a toroidal radius less than 30 μm. These are the tightest existing lab constraints on “string inspired” new gravitational phenomena.&lt;p&gt;But the key words in it mean ~nothing to me :(&lt;p&gt;So do they do anything more than constrain parameters?</text><parent_chain><item><author>ISL</author><text>A couple of us from the Eot-Wash group are active on HN.
