A beginners guide to a hidden reality: quantum mechanics and musings on a simulated reality

Intro:

“What I am going to tell you about is what we teach our physics students in the third or fourth year of graduate school — and you think I’m going to explain it to you so you can understand it? No, you’re not going to be able to understand it. Why, then, am I going to bother you

Quantum mechanics deals with the small, while General relativity deals with the large

The Heisenberg uncertainty principle

If you know, you know

Quantum entanglement

Quantum entanglement is the theory that particles are created in pairs and those pairs are inexplicably linked. To be scientific about it:

Particle A is spin up, Particle B is spin down

Quantum Teleportation

Quantum teleportation is the process of sending information from any point in the universe to any other point in the universe faster than the speed of light (maybe). This can work because of the communication pipeline that is setup when two particles become entangled. This is how the spins are communicated to the particle in the laboratory example above. Very little is known about how this connection works exactly but the basic process of quantum teleportation is as follows:

  1. If we scale this up to work on humans would it be moral i.e. making an exact copy of someone and deleting the original?
Wait but why examines the morality of quantum teleportation on humans

Quantum Computing

This can be complicated to explain, so here’s Justin Treaudeau taking a shot at it:

  1. Assuming the computing power exists, there’s not enough energy on Earth to power a computer large enough to run these simulations. One of the hidden problems in quantum computing is that you need exponentially more energy to power these supercomputers than you do with standard computing.
  • A Type II civilization can harness the total energy of its planet’s parent star
  • A Type III civilization can control energy on the scale of its entire host galaxy

At this point it is time to make a very important distinction. When you look at science, including quantum mechanics it tells you about the world. It tells you what it is. It ends there. Quantum mechanics is a system that describes reality. But when you interpret the system and start looking into how things ought to be, or what they should be it becomes a philosophical or moral conversation. As science continues to be used in pop culture these two things begin to mold together; but as a consumer it’s important to decouple the ideas so you know when something is science vs. an argument for how something ought to be. One is science and one is not. On the other hand when we use science to tell us what could be — we enter the realm of science based fiction. All three have their place, just know where you are when.

Conclusion:

The founding principle of classical physics is that a real, objective world exists, a world the scientist can understand in limitless detail. Quantum theory takes away this certainty, asserting that scientists cannot hope to discover the “real” world in infinite detail, not because there is any limit to their intellectual ingenuity or technical expertise, nor even because there are laws of physics preventing the attainment of perfect knowledge. The basis of quantum theory is more revolutionary yet: it asserts that perfect objective knowledge of the world cannot be had because there is no objective world.

Space nerd. Looking to translate complex systems into digestible ideas. Storytelling is underrated. Would prefer to be outside.
