Abstract

It is shown that an infinite gravitational flux tube solution in 5D Kaluza-Klein gravity with the cross section in the Planck region after 5D [RIGHTWARDS DOUBLE ARROW] 4D reduction and isometrical embedding in a Minkowski spacetime can be considered as a moving infinite string-like object. Such an object carries an electric and a magnetic flux. The 4D gravitational waves on the tube are considered.
