The short answer is that you have little sense of proportion.
Humans occupy the midrange of the dimension scale between the
Planck length and the distance to our
cosmological horizon. Though the extent of this physical scale is virtually unfathomable, it is instructive to examine it mathematically. Let's choose the meter [
m] as our unit of measure because it represents an easily grasped unit of length. For example, 1.8
m is a typical height for a man.
At the small end of the length scale is the Planck length, which is the smallest distance or size about which anything can be known. This incredibly small size is 1.6×10^(-35)
m [in scientific notation: 1.6 times 10 raised to the negative power 35]! That is 35 orders of magnitude (
i.e., factors of 10)
shorter than a man!
At the long end of the length scale is the distance to the edge of the observable universe, which
is now located about 46.5 billion light-years away. We need to convert this length to meters. First, the number 46.5 billion is 4.65×10^(10) in scientific notation. Next, a light year is the
distance light travels in one year, which is about 9.46×10^(15)
m. Multiplying these two huge numbers give us 4.4×10^(26)
m! That is 26 orders of magnitude
longer than the hight of a man! Together with the 35 orders of magnitude on the short end, we have a length scale totaling 61 orders of magnitude with which to compare lengths!
Considering the immensity of the numerical sweep described above, it is small wonder that our brains have evolved to make
absolute comparisons for only small numbered quantities, let us stipulate numbers in the range one to a million (to be generous). Everyone can visualize a single dollar bill. We can visualize ten of them, and even a wad of a hundred bills fairly easily. It gets increasingly harder as we progress to one thousand, ten thousand, and a hundred thousand individual bills. A million bills is a stretch.
I doubt anyone can visualize a billion individual dollar bills, which is a thousand times larger than my generous estimate of our capacity to visualize a million. What about a trillion, which is a thousand times larger than a billion? No you can't!
Have you ever noticed how often people mix up the words
million and
billion when discussing the economy? I have, but I'm used to dealing with large (and small) numbers expressed in scientific notation. We may not be able to
visualize large numbers, but we can
conceptualize them. This means that we can't make sense of comparisons involving huge discrepancies unless we express them on a scale for which our brains are wired, namely meters when comparing lengths (for example). If we discuss money (for example) most people understand what it means to have an annual salary of $40,000 and that a cup of coffee costs about $1.20 anywhere (well, maybe not at Starbucks).
When President Obama asked his Cabinet to come up with budget-cuts totaling $100 million, many people saw how ridiculous that proposal was, because if the $3.6 trillion Federal budget was scaled down to a personal budget of $40,000 the President's $100 million cuts amounted to a mere cup of coffee.
So the President upped the ante. He is now proudly proclaiming Federal budget-cuts totaling $17 billion, which, he posits, is "big bucks even in Washington D.C."! Really, Mr. President? Really?
This "great new budget-cut" is 170 times larger than his first one. BFD! So now, instead of bragging about an
annual cup-of-coffee, he's bragging about a cup-of-coffee every other day!
What is wrong with you? The short answer is that you have little common sense.
