E = mc2 Whats the magic in it?

   Albert Einstein proved that energy can be converted into mass and a mass can be converted completely into energy.
   
   In our daily life what is the significance of the idea...if man learns the ability to do so?

      E=MC^2 is famous equation associated with "Einstein's Theory of Relativity".
      
      The main significance is maybe the mass energy relationship or it could be the amount of energy it represents:
      
      1 kg mass if fully converted to energy would represent:
      
      E=1kg(3x10^8)^2=9x10^16 joules.  That is a lot of energy.
      
      There are practical limitations currently as to how much mass we can convert to energy.
      
      With everything said, E=MC^2 is just a small part of relativity.  The wonderment and idea of the amount of energy that is contained in a small mass is amazing.  That is most likely what causes most of the awe.

      The "magic" is that NOW, one species of life can (and most likely will) regress all that billions of years of evolution has produced, back to the stone age or beyond.

   we can turn gas in to energy and drive cars?

      well its something more than that....like disappearing and sublime in air and reappear...like travelling in the universe from stars to stars without oxygen.....like building high energy fuels from any ordinary matter.....something like that.

         well...I was going to say I could turn my sister in law in to enough energy to wax my kitchen floor. But I like your ideas better.

   There is no magic in the equation. The equation simply states that a little bit of matter of anything can be converted into an astronomical amount of energy. The equation explains why our nearest star, the sun, and all the other stars in the universe are able to produce so much energy from the limited amount of matter that they are made of. The sun is what gave Einstein the idea that lead him to formulate this equation.

      The equation also explains why so much energy is released after an atomic or hydrogen bomb explosion. This equation led to the development of the atomic bomb. There is no magic here. It is just a simple mathematical relationship between energy, light and the mass of matter. In essence, an atomic bomb or hydrogen bomb explosion is actually the same nuclear reaction taking place in the sun except that the reaction only last a few seconds since only a small amount of mass of matter (Uranium 235) was used.

   Have you heard that some scientists think they may have found other universes than our own?

   The magic is what “E=mc2” can be reconfigured as, i.e.:
   
   M=E/c2
   
   This proves the last step of string theory; which is that mass is a form of energy.
