(for La Monte Young)

Every valley shall be filled, 

and every mountain and hill shall be brought low; 

and the crooked shall be made straight, 

and the rough ways shall be made smooth

Luke 3:5


Draw a straight line and follow it. Time goes from A to B, or from B to D, that is, from one point to another; its way draws a horizontal straight line that grows vertically, like a snowflake landing on the top of a mountain, rolling straight down the slope, accumulating snow while descents, growing, rolling, getting fatter. The space is expanding, and with it, time. Temporary expansion happens not only in its passing, that is, on the constant creation of instants, that, if they were put one above the other, they would filled the barrel of infinity. Time expands in its duration: every second lasts longer than the last, but unlike and independently of the twin paradox, or the different length of time in two different gravitational forces, we don't have access to a time outside of the universe that allows comparison, a second always lasts a second, but its duration is different from the original second. Assuming that the expansion of space is directly proportional to the expansion of time, using the Hubble constant –which is not constant, neither accurate, and in almost a century that has existed has readjusted its value in more than 80%–, each second increase 0.007% from the previous. Using, as Augustine of Hippo, music as an instrument of time measurement, a song that was released the same year that Hubble published his constant: Singing in the Rain, the version by Cliff Edwards recorded in 1929, takes 2:12 minutes, updated to present time, it would increase 792 nanoseconds in its duration; or, the first composition in history that is preserved complete: Seikilos epitaph, in the more than two thousand years that have passed since the song was written, it would have increased 155.05 nanoseconds in the duration of each of its seconds ; the different interpretations of Seikilos epitaph vary in their length, perhaps, the duration more accurate to the score is when it is play through a MIDI file, this version lasts 72 seconds, bringing it to present value, we would have to add 11.1636 microseconds , equivalent to the time a bullet takes to cross the space between the skin and the heart, or the time that takes a single sound wave of the singing of a whale to complete a period; Seikilos sings: “While you live, shine / have no grief at all / life exists only for a short while / and time demands a toll”, time requires and pays tribute to himself in order to expand and make that every 9,902,450,000 years, each time unit doubled its value, like a snowflake that rolls and accumulates snow in its descent.



Draw a straight line and follow it. We say that we walk in straight line when we headed toward a point, from A to B, or from B to D, however our journey is not an ideal straight line, but a line that fits into the surface in which we move: geodesic line. To optimize displacements, civilization has built roads and highways that try to be as close to a straight line as is possible: one hundred meters an average block, two hundred and sixty kilometers the longest straight road, located in the desert of Saudi Arabia, followed by the hundred and seventy kilometers of straight road across the Baja California desert, and the hundred forty six kilometers of straight road across the desert of Australia. A desert is a labyrinth from which you can only scape by moving in straight line.

A straight line allows a body to reach its highest speed. On December 8th 1913, during a hunting trip, Camille Jenatzy hides behind a bush, imitates the roar of a wild boar in order to mock his hunting companions, one of them, Alfred Madoux, hear the sounds, shoots and kills him. Camille, "The Red Devil" Jenatzy, went down in history as the first man to drive a car over 100 km/h, the record was broken aboard the "Never Satisfied", in the central straight road of the agricultural park in Achères, France. A line followed by another line: The straight line in which Camille drove his car, and the straight line of the bullet with he found.

Everything intervenes in the trajectory of a bullet: temperature, humidity, altitude relative to sea level, aerodynamic drag, curvature and rotation of the Earth, muzzle velocity and force of gravity. Before 1685, when Newton published the law of universal gravitation, it was believed that a bullet traveled in straight line until muzzle energy dissipates, then collapses vertically.

The gun that shoots a bullet with the highest muzzle velocity is the .223 Winchester Super Short Magnum, it shoots at 5047,488 km/h; to get that a bullet travels in a straight line, it must, above all, overcome the force of gravity, i.e., to travel at 40320 km/h –7.98 times faster than the bullet propelled from the most powerful gun–, and maintain that speed for its entire length, so the bullet would draw a tangent line that would leave the Earth without changing its direction, until it meets another gravitational force that re-directs it.

Draw a straight line and follow it. Like a bullet, to walk in straight line force us to leave the Earth's surface: the straight line propels us into space, just taken the first step, we would have raised 780 picometers, two more steps and 7000 picometers separate us from the floor, and having travel just over three kilometers and a half, we would be walking a meter above the Earth, we walk away from the planet taking logarithmic steps. Following our way through this straight line, drawn over a three-dimensional snapshot of the universe, walking slowly, an average of twenty kilometers a day, in two months we would be crossing the Kármán line, turning the Earth's atmosphere in our outer space, losing all perpendicularity to her.
