An interesting observation about the size and scale of humans in relation to the rest of the universe is the following. "You are a planet."
The current model places the smallest objects around 10^-35 meters, while the largest, the known observable universe, is about 10^26 meters. This creates a full scale of 10^61 degrees of magnitude in base 10. Moving the reference point of measurement to 0 on the scale gives an average size object of 10^30.5 magnitude, and places humans at 10^35 magnitude. This means that humans are roughly 35/61 = .57 of total magnitude, which is 7% larger than an average sized object.
This has some interesting implications, 3 of which are the following.
One, it may be a byproduct of the fact that one might expect or observe that our technology is about as limited in its ability to measure small things, as it is in its ability to measure large objects. So by default we end up average sized from our perspective.
Two, it still means though, that from our view, that humans are that 7% larger than we are small. When asked if humans are large or small in the scope of the universe, most people think from the universal perspective and answer that we are small, instead of thinking from the quantum side and saying that we are large. However, the scale perspective suggests that we are in fact slightly large. This leads to the 3rd implication mentioned.
Three, since planets are only different in scale compared to humans by another 10^6 magnitude of 10^61 overall, that relative to the scale of the universe, humans are within the same 10% magnitude of objects as planets. That is, if you separated all objects into 10 groups by size, humans would be in the same group as planets, or within 1 group away depending on where you placed the bounds of each group. From the perspective of the Universe, we're pretty much miniature sized planets walking around.
Of course the actual size of the universe is different from the observed, and using a different scale would change the representative numbers of some of the stated relations, however, it's the best we have at the moment, and until it changes, I'll bet most people haven't thought of themselves as planets before. Now think about all the micro organisms that live in or on your body, and draw the comparison to humans living on a planet. Maybe 'Horton Hears a Who' and 'Men in Black' aren't as far fetched as they seem.
Anyways, I hope you enjoyed that perspective, and remember to mind your orbits.
