The big bang model makes it sound like the universe started at a point and exploded for some reason, spraying matter out into empty space, but that isn’t really what it is saying. We aren’t inside a 3D sphere so much as we are on the three-dimensional surface of a 4 dimensional hypersphere. For some reason, the hypersphere is expanding, which means the 3-dimensional space on the hypersurface is expanding, which is why stuff seems to be going away from us.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:18.0pt;font-family:"Comic Sans MS"'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:18.0pt;font-family:"Comic Sans MS"'>Note I am not claiming to understand it, but doing the math helps, just as calculus helps the physics student.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:18.0pt;font-family:"Comic Sans MS"'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:18.0pt;font-family:"Comic Sans MS"'>spike<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:18.0pt;font-family:"Comic Sans MS"'><o:p> </o:p></span></p></div></div></div></body></html>
