Doesn't explain the apparent lack of antimatter though.
Well if you can explain that then you can get your name enshrined in science forever. :P Baryon Asymmetry is still one of our big unproved problems in science.

That's one of those rules that seems totally true, but when you get to the higher levels they are like, "Well, technically it can't be created or destroyed, but since mass and energy are the same thing, you can take a huge amount of energy can convert it to a small amount of mass, or take a small amount of mass and convert it to a large amount of energy." Thus lots of energy in the big bang -> small amounts of mass in the universe. :P
That's like trying to explain which came first, chicken or egg - without answering where either chicken or egg originated from

Scientific constants generally don't make much sense.
It depends on what do you mean by "making sense". From a certain viewpoint, scientific constants are the only thing that makes sense.

Well, naturally. From a 'round base ten number' viewpoint though...

tbh we should all switch to base e, it is the most efficient, after all :v

I was thinking more alongside "change the system of measurements where speed of light equals 1" and so on...

Aye, defining constants as 1 is pretty standard practice after a certain level of physics.

Hell, it even creeps in beforehand - atomic masses sure as hell ain't measured in kilos :P

Oh, sure - I just don't think it's practical in day-to-day life. :P

what are you talking about

it's totally practical to use nanolightseconds to measure common distances

What about using planck units? it makes everything simpler because you're incorporating physical constants into all your input values anyway.

The average human male is approximately 3.2*10^9 planck masses.

In the days when Sussman was a novice, Minsky once came to him as he sat hacking at the PDP-6.
“What are you doing?”, asked Minsky. “I am training a randomly wired neural net to play Tic-Tac-Toe” Sussman replied. “Why is the net wired randomly?”, asked Minsky. “I do not want it to have any preconceptions of how to play”, Sussman said.
Minsky then shut his eyes. “Why do you close your eyes?”, Sussman asked his teacher.
“So that the room will be empty.”
At that moment, Sussman was enlightened.

Avogardo's Number IS rounded up - when you don't need precision. Like others said, it cannot be moved in value because it's a conversion factor between two arbitrary mass units established independently from each other, but in some applications, 'Fuck that, it's a 10' is used in sciences, mostly for rough top-off-my-head estimates.

It depends on what you use; it's a shame to waste precision of a jillion dollar pipetting apparatus or something with rough concentration calculations, but if you're trying to fill an eppendorf with a shovel, no point in including ALL THE DECIMALS since the equipment error itself will make the result diverge from the calculated ideal.

We are doomed. It's just that whatever is going to kill us all just happens to be, from a scientific standpoint, pretty frickin' awesome.
