You pose interesting questions Dipayankar. Here are my thoughts. Absolute zero means no movement and therefore no heat. Absolute hot, therefore would probably mean absolute movement, perhaps your question is a key to explain how there was spatial inflation and how space could move faster than light. Here is a post describing the first second after the "big bang". The entire post is located at: ( http://www.geocities.com/lungdoctor_...ory.htm?200718 ) The First Second<SPAN style="mso-bidi-font-size: 12.0pt">. One microsecond after the creation of the universe the temperature was about 10 trillion degrees K – about a million times hotter than the center of the Sun. The glow of radiation would have been intense and uniform in all directions, and there would have been a bright fog that limited vision to a small fraction of a centimeter. The high-energy gamma rays that made up most of the radiation at that time were so energetic that they were capable of pair production. Pair production is the production of matter from energy whereby the collision of two photons yields a particle and its antimatter counterpart. Therefore, one set of products of pair production is an electron and a positron (which is as massive as an electron but has a positive charge). Other possible pairs would be a neutrino and an antineutrino, and many others. Pair production is one of the most spectacular consequences of Einstein’s famous equation; E=mc2. For two photons to produce a pair of particles, these photons must have energy at least equal to mc2, where m is the combined mass of the particle and antiparticle, and c is the speed of light. A microsecond after the universe began, the gamma ray photons present had sufficient energy to produce protons, neutrons, electrons and their antiparticles.
