<b>Galaxy Collisions</b><br>
<i>Allison W.S. Man (ESO)</i><span style="font-size:0.9em"></span><br>
<br>
<font size="-1">The Milky Way is bound for a head-on
collision with our neighbour galaxy, Andromeda. Galaxy
collisions are common in the early Universe. They are
thought to build up the most massive galaxies, turn spiral
galaxies into elliptical ones, and trigger the strongest
starburst and most active black holes. The merger of two
supermassive black holes in two galaxies is also expected
to emit gravitational waves, that will be detectable with
future space missions. How does this spectacular
phenomenon influence the life of galaxies? What can we
learn by observing colliding galaxies with the largest
telescopes on earth?</font><br>

<b>The Twin Paradox and its resolution</b><br>
<i>Boris Lohner (Volkssternwarte München)</i><span
style="font-size:0.9em"></span><br>
<br>
<span style="font-size:0.9em">Explanations of the twin
paradox sometimes give the impression that special
relativity is defective and that this "defect" requires
general relativity to be "repaired" - or give the
impression that time dilation is not real but a mere
effect of observation.<br>
In this talk it is shown how the twin paradox can be
resolved in a consistent way while staying within special
relativity. Three days later, Boris Lohner shows the
mathematical background to this talk in our <a
href="http://www.sternwarte-muenchen.de/kolloquium.html">colloquium</a>.</span><span
