Perhaps one of  the most beneficial discoveries civilisation
          could make is  that  the  Second  Law  of  Thermodynamics is
          misunderstood (more correctly, incompletely understood). The
          2nd Law says  that  in a closed system with no energy coming
          in, disorder or  entropy must increase - heat flows from hot
          to  cold,  eventually  averaging  out  in  random  molecular
          disorder and offering  absolutely no hope for an everlasting
          existence of the cosmos.

          If the ideas  I've  previously  enclosed about recycling the
          cosmos (along with  this week's enclosure) are correct, then
          everlasting existence of  the  cosmos  (a  central  idea  of
          Steady State theory) is absolutely guaranteed!

          After reading the 'Science Classics' cartoon by Larry Gonick
          (DISCOVER magazine, July  1991), a few ideas came to mind. I
          don't know if  these  make  me  a  crank,  a scientist or an
          optimist (to borrow  some  terms from the cartoon) - but I'm
          going to try  to  enterprisingly  and  boldly go where James
          Clerk  Maxwell  and  Cariton  Caves  have  not  gone  before
          (Maxwell and Caves  are  two  scientists  mentioned  in  the
          cartoon   as  having   worked   on   the   Second   Law   of
          Thermodynamics). I'm enterprisingly  and boldly going to the
          final frontier on  the  Search  for  Vanishing  Entropy (who
          knows - Spock might be there, too).

          This argument arises  from  a  statement in 'Time travels in
          diverse paces' by  Anantanarayanan Thyagaraja (NEW SCIENTIST
          magazine, 8 April  1989):  '.  .  .  if we put the system (a
          small bead sliding  on  a  circular  wire) in a smallish box
          with  walls  that   perfectly   reflected   the  waves  (the
          accelerating bead emits gravity waves), the system would not
          decay.'

          Speculating that the  Law  of  Conservation  of  Mass-Energy
          (mass-energy may not  be  created (* What last week's letter
          to Science Wish  List  called  a  'creation  point'  is more
          properly referred to  as  a  'recycling point) or destroyed,
          but each may  be converted into the other) is the universe's
          practical equivalent of  this  perfect  reflection gives the
          following: if the  universal  system is finite (analogous to
          'a smallish box')  and  obeys  the  Law  of  Conservation of
          Mass-Energy, that universe  will  violate  the  2nd  Law  of
          Thermodynamics.

          It's a scientific  fact  that the 2nd Law cannot be violated
          in a closed  system  with  no  energy  coming in - so if the
          universe we live  in  (according  to this manuscript, it's a
          closed system comprised  of  space,  subspace and hyperspace
          and with a  'void'  outside  it  which  is a vacancy for the
          eternal expansion of  its  infinite subuniverses) is to last
          forever, there must  be  energy  coming  in to the universal
          system.  This  energy   influx  may  come  from  a  particle
          accelerator transmitting energy  to  20  lbs.  of matter and
          producing a cosmos-generating  mint  black hole. It may also
          lend support to  the belief that other subuniverses interact
          with (put energy into) our local finite subuniverse. Drawing
          on cosmological equations  worked  out  by  Albert  Einstein
          nearly 80 years  ago  reveals  that these other subuniverses
          must be two in number and infinite.

          'Time travels in  diverse paces' also says 'If all the beads
          could act as one . . . the system would stay reversible.' So
          time travel would  be  scientifically possible if all things
          (including beads) can  act  as  one  (this  means some Grand
          Unification Theory and  some  Theory of Everything has to be
          successful).

          If other subuniverses exist..and if time travel is possible,
          maybe taking trips  through  time  is achieved by travelling
          via these other subuniverses. Is entry to these subuniverses
          gained by means  of  wormholes?  Could these subuniverses be
          called subspace and  hyperspace?  If  a  wormhole provides a
          shortcut by tunnelling  through  the  curvature  of space to
          hyperspace and back,  can  it  be  used  to attain seemingly
          faster-than-light speed?
