With the advent of general relativity it has been entertained by serious physicists. But, especially in the philosophy literature, there have been arguments that <a name="2"></a><A HREF="../../Notes/Notes_11/Notes_1133.htm">time travel</A><SUP>2</SUP> is inherently paradoxical. The most famous paradox is the grandfather paradox: you travel back in time and kill your grandfather, thereby preventing your own existence. To avoid inconsistency some circumstance will have to occur which makes you fail in this attempt to kill your grandfather. Doesn't this require some implausible constraint on otherwise unrelated circumstances? We examine such worries in the context of modern physics. </ol> </FONT><BR><U>Contents</U><FONT COLOR = "800080"><ol type="1"><li>A Botched Suicide</li><li>Why Do <a name="3"></a><A HREF="../../Notes/Notes_11/Notes_1133.htm">Time Travel</A><SUP>3</SUP> Suicides Get Botched?</li><li>Topology and Constraints</li><li>The General Possibility of <a name="4"></a><A HREF="../../Notes/Notes_11/Notes_1133.htm">Time Travel</A><SUP>4</SUP> in General Relativity</li><li>Two Toy Models</li><li>Remarks and Limitations on the Toy Models</li><li>Slightly More Realistic Models of <a name="5"></a><A HREF="../../Notes/Notes_11/Notes_1133.htm">Time Travel</A><SUP>5</SUP></li><li>Even If There are Constraints, So What?</li><li>Quantum Mechanics to the Rescue?</li><li>Conclusions</li><li>Bibliography<BR>Other Internet Resources<BR>Related Entries </li></ol> </FONT><hr><FONT COLOR = "0000FF"><B>Comment: </B><BR><BR>Recommended by <a name="6"></a>"<A HREF = "../../Abstracts/Abstract_19/Abstract_19191.htm">Richmond (Alasdair) - Time Travel and Philosophy</A>".
