SCHOOL IS BACK IN SESSION
I understand all your puzzlement. And It's ok. But you all need to rethink your hypothesis. Expand your mind. THink outside of the box.
Think of the UNIVERSE as a container. It cannot contain anything larger than what its capacity is--whether that be a certain number of planets or stars or combinations of atoms, etc. Assuming the total number of atoms in the entire universe is 10^80, then it cannot contain anything REAL beyond that number. I'm not sure why so many people find that difficult to grasp. Indeed, HYPOTHETICAL numbers can exist that would dwarf 10^81 such as googolplex^googolplex. But it is a hypothetical number. IM TALKING REAL NUMBERS. LISTEN TO THE SCHOLAR....PLEASE!!!
The number 10^120 may indeed be REAL, but it does not....CANNOT exceed a number that is used to denote the universe's total makeup. You wouldnt want the universe to explode, would you?
The process that was used to come up with 10^81 atoms in the universe was: total number of atoms per star 10^57 times total number of stars 10^24. Total number of planets 3 x 10^24 times total atoms per planet 9 x 10^49. Add them together and you get about 10^81. THe numbers are averages.
Now, space CONTAINS atoms. We all know there are atoms that float around in space and that's where the MONSTROUS numbers come into play. Numbers that have not even been thought about. THere is no value assigned. Trust me on this people that 10^120 is INSIGNIFICANT next to this number. The bottom line is that it HAS to be smaller or wither the container will BURST or the number is imaginary.
It's not arrogant at all. We know how much mass is required to fit our observations, and we know how much we can see. Pretty easy to turn it into a percentage. The weighting of dark matter to dark energy is going to be less reliable, but we can still say quite happily what their total weighting is wrt regular matter.
