Hidden In Plain Sight: The simple link between relativity and quantum mechanics

by Andrew H. Thomas

s2 = (ct)2 — x2

awww snap, completely see why it's invariant s and not really relativity

This invariant quantity — that everyone is moving in spacetime at the same speed — gives us a different way to look at Einstein's theory of special relativity. When we combine space and time into spacetime, we find that all observers move through spacetime at the same speed.

"We now see that time slows down when an object moves relative to us because this diverts some of its motion through time into motion through space."

By limiting the term "reality" to mean physical reality we are immediately rejecting any notion that dreams, or ideas, have any form of reality — at least by our definition. Reality — in our book — refers to physical objects we can touch and hold. This means the material of reality is, essentially, matter.

solipsism

but what if that is the case

The properties of any particle — or any object — are determined by all the other objects in the universe.

so I should care what others think of me

What would it mean to assign property values to this isolated object?

It does not just seek to describe quantum mechanical behaviour, it seeks to explain it.

We should only add complexity to our explanations as a last resort,
