<p>I was just at the TSC conference where twisted light creating
vertexes was proposed for penetrating tissue <br>
</p>
<p>The pictures presented clearly showed light beams with doughnut
shaped propagation wave fronts.</p>

<p> I asked the presenter if double slit experiments or single
photon experiments had been done with these light forms.
Apparently the angular momentum of light is theoretically found
when solving Maxwell's equations in cylindrical coordinates , but
currently uses are for intense beams, but there is no obvious
reason low intensity beams could not show the same phenomena.</p>
<p>The question of the wave front size of light came up and it was
agreed that this was an open question. I know in our group we have
discussed whether the wave front is contained in the apparatus and
thereby the properties of photons cannot be separated from the
propagation environment boundary conditions.<br>
</p>
<p>Could gravity also form vortecies? Even more intriguing could a
vombination of gravitational and electric fields produce
vortecies?<br>
</p>
<p>Anyone know more about this?</p>
