SUMMARY:Can there be a discrete theory of gravity?
DESCRIPTION:Featuring Prof. Gerard 't Hooft\, University of Utrecht\n\nPart
	 of the HET Seminar Series.\n\nElementary particles are surrounded by gravi
	tational fields that vary continuously from point to point\, and for that r
	eason it is difficult to use them as elementary constituents in a discretiz
	ed theory. If matter is assumed to consist of straight sections of strings 
	this problem does not arise. At first sight\, the spectrum of strings\, str
	aight or otherwise\, would still allow for a continuum of orientations and 
	velocities\, but this can perhaps be cured. An interesting discrete theory 
	of gravity emerges that sheds an unusual light on the quantum nature of our
	 world.\n\n This talk is about work still in progress.
