  1. The universe BB model was not an explosion nor does the universe has a center. It is a rapid expansion of space. Not a kinetic type explosion. Here is some material please read the misconceptions of the big bang Lineweaver and Davies in particular. Misconceptions (Useful articles to answer various Cosmology Misconceptions) http://www.phinds.com/balloonanalogy/: A thorough write up on the balloon analogy used to describe expansion http://tangentspace.info/docs/horizon.pdf:Inflation and the Cosmological Horizon by Brian Powell http://arxiv.org/abs/1304.4446:"What we have leaned from Observational Cosmology." -A handy write up on observational cosmology in accordance with the LambdaCDM model. http://arxiv.org/abs/astro-ph/0310808:"Expanding Confusion: common misconceptions of cosmological horizons and the superluminal expansion of the Universe" Lineweaver and Davies http://www.mso.anu.edu.au/~charley/papers/LineweaverDavisSciAm.pdf:"Misconceptions about the Big bang" also Lineweaver and Davies The balloon analogy is also handy
  2. Neither time nor space is being created... the geometric volume of space simply increases. One of the most common mistakes is to try and define space with some fabric like property. Space itself has no energy or fabric. It is a geometric volume that is simply filled with the energy-mass from the rest of the universe. That being said the superluminal velocity measurements of expansion is a consequence of the separation distance and the Hubble flow. Hubble's law. The greater the distance the greater the recessive velocity. [latex]V_{recessive}=H_Od[/latex] the subscript o meaning the hubble parameter today, which is constant only in time..meaning at a particular time Its not a constant as per se a consequence of Hubble's law is that when recessive velocity becomes greater than the speed of light, this region is described as the Hubble radius or sphere. However the recessive velocity is not an inertial velocity hence as mentioned, as only the volume is increasing and expansion is not a consequence of inertia, GR and SR do not apply. This recent article written by a physicist friend of mine, covers this in excellent and well written detail. With very little math involved as his target audience is the general public http://tangentspace.info/docs/horizon.pdf :Inflation and the Cosmological Horizon by Brian Powell this is another good article http://arxiv.org/abs/astro-ph/0310808 :"Expanding Confusion: common misconceptions of cosmological horizons and the superluminal expansion of the Universe" Lineweaver and Davies We This is incorrect we can see farther than the Hubble sphere, Much farther. We can measure recessive velocities at z=1080 at around 3c. See the first article I posted to see why. correct
  3. The terms created, stretched etc is VERY misleading. Space itself has no substance, fabric or energy. Space is simply geometric volume that is simply filled with the contents of the universe. However an important consequence of having a region of volume is that you will have a vacuum energy-density at the very least. This does not mean that the volume has a fabric or energy property. A volume of space is simply a filled region. Space geometry changes due to gravity is simply a descriptive of its energy-density distributions. The term warping of space is also a poor and misleading descriptive.
