Subject: could a laser be used to create a pulse of light whose kinetic energy

     Could a laser be used to create a pulse of light whose kinetic energy would
equal the mass of say, a brick, by way of e=mc2. Also would the damage cause by
this "light brick" be comperable to the damage from a true brick flying at the
speed of light.  I suspect the "light brick" would cause much less damamge.  
     By the by, sorry about all these questions, this must be my 30th since i
found your site. You guys are great. Keep up the good work.
