sir
this is my second mailabout the same topics because ido not get any reply of the previous mail.Please give the response for my idea which is as follows

After 3 billion years when sun expands and
covers almost all the distance between earth and sun
and turn the earth to magma, then is it possible to
save the earth? I think that as solar heat comes to
earth in a form of magnetic wave,and if we charge
the magnetic wave face to face by laser , then it is
possible to stop the magnetic wave, though it will
be costlier,i think it is possible.Please give the reply and explanation..

Won't work. The sun can concentrate far more energy than we can on earth. And the sun will be expanding materially, not just shooting out electromagnetic waves. The earth will be surrounded by, bathed in, a material atmosphere of gases at thousands of degrees temperature.
