My friend Trevor and I used to discuss the infinite all of the time. One of our many topics included light travel. My joke was that in order to travel ‘light’ you can’t have any human baggage.
At age 23, it was obvious to me that light has to catch up to the black holes we call our eyes in order to be perceived. How can we accurately measure the movement of something when the measuring device is also moving at an uncalculated speed? I think Einstein did too much Cocaine.
Regardless of this, we would pretend to be theoretical physicists and postulate all sorts of notions. One of these notions had a prop… scissors.
We close the scissors and imagine a line that extends toward infinity from the blades. Once the imaginary line reaches a distance that is almost unfathomable, we then open and close the scissors really fast. Here on Earth we are simply opening and closing scissor blades. Our imaginary lines are travelling at incomprehensible speeds toward infinity however.
To simplify this even further, imagine two lines extending toward infinity from the open blades. The blades reach 186,000 miles apart (approximate light speed per second). Close and open them four times per second and you have (theoretically) demonstrated a speed four times faster than light speed.
This is the first time I’ve tried to explain this with words so I thank you for your patience:) I used to explain it with acid and a series of grunts and laughs.
