Tufail, would you explain this please :- "<span style="font-family: Arial, Helvetica, sans-serif; font-size: 12.8px;">Speed of light </span><span style="text-decoration: underline;">(as we observe at present moment/era)</span><span style="font-family: Arial, Helvetica, sans-serif; font-size: 12.8px;"> is so fundamental to the nature of reality , that without it space-time will cease to </span><span style="font-weight: bold;">evolve and expand</span><span style="font-family: Arial, Helvetica, sans-serif; font-size: 12.8px;">, which becomes a motion-less Universe."</span><div>Do you mean the speed of light being the value that it is. and it has to be that value, or would any other constant speed do? Also do you mean c WRT all observers (which has not been proved, despite claims that it has), or c WRT its source .</div><div><br></div><div>Tom Hollings.</div><div><br>
