It really is a mind-blower. In all our experience, in our calculations, we work in three dimensions. To understand cosmic inflation, one needs to work in four dimensions, and do it enough that one starts to think in four dimensions. Then the notion of 3-dimensional space expanding with the galaxies embedded in expanding 3-space all makes sense. It becomes the only way to explain what our telescopes tell us.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Now however… with the new Webb results coming back… our standard model is once again having some difficulties. The LIGO results are still blowing our minds, with all those mergers this late in the day. I don’t get that one at all. How can there still be so many mergers? Those shoulda been once-a-century events rather than several a year. I am as baffled by that as 3-space people are with cosmic inflation.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>spike<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
