Block Universe: Is Free Will an Illusion? (Part 4)

A #blockuniverse contains all time and space. Everything. Everywhere. Everytime. What does this mean for free will? ⏳ This series sponsored in part by CuriosityStream + Nebula! Join now! It supports the channel and you get the lowest price anywhere.

The Block Universe Theory is one model of the universe which was created to describe the concept of time in a simple way. Basically: everything already happened, and it’s inside this ‘block.’ Thus, time is just another coordinate that can be plotted within this a-temporal block! I know, it’s crazy, and yet, it’s the most accepted way to talk about time (though not the ONLY way). 🤔

Time is a construct that we humans invented to try and explain the changes and movements of the universe that are happening around us. Time is our way of trying to bring order to cosmic chaos. So, you could say that this series is me, trying to bring a little order to my understanding of time! Where did time come from? What is time? Where does time exist? What is the base unit of time? Why do we even need time? Why does time seem to slow down when something crazy happens or when you’re bored? How did time come to be? What about relativity and quantum mechanics? What the HECK is this thing we call TIME?! You’ll have the answers. Let’s kick into it.

An Einstein-Minkowski Light Cone Diagram (Fig 9)
A Minkowski spacetime light cone diagram shows the different causal regions corresponding to an event E= (0,0,0,0) at the origin. The timelike regions (inside the light cones) are regions where there can be a causal relationship between the event at the origin and an event within the timelike regions.

Free Will in the Block Universe?
Since Einstein‘s theories of special and general relativity were accepted by the scientific community, a good deal (perhaps most) of the specialists in this branch of physics have favored the world image called the block universe.

A Debate over the Physics of Time
Einstein once described his friend Michele Besso as “the best sounding board in Europe” for scientific ideas. They attended university together in Zurich; later they were colleagues at the patent office in Bern. When Besso died in the spring of 1955, Einstein — knowing that his own time was also running out — wrote a now-famous letter to Besso’s family. “Now he has departed this strange world a little ahead of me,” Einstein wrote of his friend’s passing. “That signifies nothing. For us believing physicists, the distinction between past, present and future is only a stubbornly persistent illusion.”

The Planck Scale
In the late 1890s, physicist Max Planck proposed a set of units to simplify the expression of physics laws. Using just five constants in nature (including the speed of light and the gravitational constant), you, me and even aliens from Alpha Centauri could arrive at these same Planck units.
