<h3>Some random facts:</h3>
<font size="5">
<ul>
<li>Black holes aren't black they are transperent because to have any color an object must reflect light and black holes take in light not reflect it</li>
<li>Nothing can escape a black hole"s gravational pull</li>
<li>If you survive going through a black hole then in theory you come out a white hole</li>
</ul>

<font size="4">
