SI stands for Standard International Units m, Kg, s, m is the abbreviation for meters. Kg is the abbreviation for Kilograms. s is the abbreviation for seconds. G is the symbol for the Universal Newtonian Gravitational Constant. h is the symbol for Plank’s constant. c is the symbol for the speed of light. SI () as a function yields the SI units of the object Newton’s second law F=Ma where F is the force, M is the mass, and a is the acceleration. Newton’s Universal law of gravitation F=G M m/R2 where F is the force between mass M and other mass m separated by a distance of R and G is the Newtonian universal gravitational constant. F=ma=GMm/R2 Kg m/s2=SI(G) Kg2/m2 SI(G)= m3/(s2Kg) SI(h)=Kg m2/s2 * s SI(h)= Kg m2/s SI(Gh)= m5/s3 SI(c)=m/s SI(Gh/c5)= m5/s3 (m/s)-5= s2 SI( (Gh/c5)1/2 )=s SI( (Gh/c3)1/2 )=m (Gh/(2c5))1/2=5.3905x10-44st0 the Planck time, a chronon, smallest time, quanta of time, when! Time is quantitized at this level, so called “third quantitization.” (Gh/(2c3))1/2=1.6160x10-35m10 the Planck length, an extention, smallest length, quanta of distance, where! Space is quantitized at this level, so called “third quantitization.” SI(h/G)= Kg m2/s (s2Kg)/ m3= Kg2s/m SI(hc/G)= Kg2 SI((hc/G)1/2)=Kg (hc/(2G))1/2=2.17671x10-8 Kgm0 the Planck mass, which signifies who knows what? SI(h/c)=Kg m The current age of the universe is around 13.7x109 years. The universes current radius appears to be around 46x109 light-years not 13.7x109 light-years (as I had previously thought when I had neglected the acceleration of the universe), because the universe is not only expanding in space and advancing forward in time, but for the last several billion years the rate of expansion has been increasing, the so called acceleration of the universe. “Dark Energy” is the place holder for the causes of this effect that we see, but do not understand what is causing it. “Dark Energy” is not related to “Dark Matter,” which is the place holder for the cause of the flat velocity rotation curve in galaxies and the cause of the specific velocity dispersion between galaxies in a clustering of galaxies. “Dark Matter” is not the same as “Dark Energy” the only thing they share is that they are both dark, they do not produce photons, electromagnetic radiation, and our understanding of what they are also is dark. We only have candidates for what the “Dark Energy” and “Dark Matter” might be; and none of these candidates to “Dark Matter” or “Dark Energy” have been discovered yet. Things like electrons, protons, neutrons, and neutrinos can be said to have been discovered; and to be understood in some sense of the word. None of the “Dark Matter” or “Dark Energy” candidates like Axeions, neutrilinos, squarks, or darkon (I think, I just made up the last one darkon, but who knows what some tortured particle physicist may have used darkon in desperation before me.) or quintessence can be said to have been discovered when this was modified last on February 12, 2005. The previous paragraph was to justify the 46x109 light-years radius of the universe, so an estimate of the current information content, pixels, of the universe, since creation could be made. So here it is the current estimate of the information content of the universe, which is an always increasing number, because time is advancing; we get older and not younger; it’s a one way trip; no time travel allowed (you can not kill your mother before you were conceived); and the universe is expanding and accelerating since the creation event: 13.7x109 years/t0*4/3*(46x109 light-years/10)3 =6.6x10245.
