Why do I remember the most meaningless and menial things, such as which page a certain song is on in my musical script, but fail to remember larger and more important things, such as the due date for homework or my actual lines in the musical? I also know the caffeine content of a 12 oz. can of Mountain Dew, 54-mg of caffeine, and a 20 oz. bottle of Mountain Dew, 91-mg. People call me weird for that quirk, probably for good reason. I also sometimes subconsciously memorize other people’s lines in the play. It doesn’t happen often, but when it does, it is quite odd.

Technically, no one person’s perception of the world around them is the same as the next person’s. Everyone’s perception of the color red is generally the same, but we have no objectively based perception of color. We are all taught that certain colors are what they are according what society calls them. So, theoretically, if we stumble upon a new tribe of humans, kept isolated from the rest of society, they could perceive our “red” as their “blue.” As Jamie Abbott puts it, “Colors are just pigments of our imagination.”

According to the multiverse theory, there are an infinite number of parallel universes. Because of this possibility, it means that there is technically a universe in which I am .0000000000000001 centimeters taller. Because of the infinite possibilities, there are so many things that we can change in such miniscule ways that the universes would be nearly identical. While this particular thought is intriguing, what’s even more intriguing are universes where certain constants and defaults within our own universe are completely different. For example, 2+2=5. This is only true if the concepts behind the numbers 2 or 5 are different, e.g., 2 actually equals 2.5 in another universe, or 5 equals 4 in that universe. The philosophical concepts behind these numbers would not change themselves, but what we perceive as 2 or 5 can change. There are so many unique possibilities that I could go on forever, but it’d start to get rather boring.
