On that theory, rather than having a <a name="2"></a><A HREF="../../Notes/Notes_11/Notes_1133.htm">time traveller</A><SUP>2</SUP>, S, journey into the past of his own universe (call it 'a') and thereby court the apparent contradictions, we can instead posit an alternative universe ('b') as his proper destination. The event of S's departing the year 2001 for the year 1001 (say) will therefore be more precisely described as S's leaving his own universe and time, 2001a, and travelling not to 1001a, the ancestor of his own time, but rather to 1001b, i.e., the year 1001 in another universe. It follows, say the advocates of the multiverse, that any action S undertakes after travelling to the past occurs in an alternative universe and so cannot affect  and, a fortiori, contradict  the events of his own. </ol></FONT><FONT COLOR = "0000FF"><HR></P><a name="ColourConventions"></a><p><b>Text Colour Conventions (see <A HREF="../../Notes/Notes_10/Notes_1025.htm">disclaimer</a>)</b></p><OL TYPE="1"><LI><FONT COLOR = "0000FF">Blue</FONT>: Text by me; &copy; Theo Todman, 2018</li><LI><FONT COLOR = "800080">Mauve</FONT>: Text by correspondent(s) or other author(s); &copy; the author(s)</li></OL> <BR><HR><BR><CENTER> <TABLE class = "Bridge" WIDTH=950> <TR><TD WIDTH="30%">&copy; Theo Todman, June 2007 - August 2018.</TD> <TD WIDTH="40%">Please address any comments on this page to <A HREF="mailto:theo@theotodman.com">theo@theotodman.com</A>.</TD> <TD WIDTH="30%">File output: <time datetime="2018-08-02T08:40" pubdate>02/08/2018 08:40:34</time> <br><A HREF="../../Notes/Notes_10/Notes_1010.htm">Website Maintenance Dashboard</A></TD></TR> <TD WIDTH="30%"><A HREF="#Top">Return to Top of this Page</A></TD> <TD WIDTH="40%"><A HREF="../../Notes/Notes_11/Notes_1140.htm">Return to Theo Todman's Philosophy Page</A></TD> <TD WIDTH="30%"><A HREF="../../index.htm">Return to Theo Todman's Home Page</A></TD> </TR></TABLE></CENTER><HR> </BODY> </HTML>
