I often wonder if our universe is real or some kind of simulation.
Is there a way to know? Does it matter?
From what I have read, the latest thinking is that the universe is indeed real. That the computational power required to simulate the universe would be more than what would be possible.
I have a couple of problems with this explanation.
1. How do we know what is possible outside our universe?
2. The computational power needed is based on the simulation running in real time.
It is possible that outside of the simulation each second could take hours, days, years or even a millennia to render and we wouldn’t notice the difference within the simulation. When watching a cartoon do we notice that each frame took hours or days to create? The more time it takes to render, the less computational power the simulation needs.
Perhaps, the whole universe isn’t being simulated at once, just a particular point of reference. Maybe just your life and interactions are all that is being simulated. Nothing exists except that which intersects with your life.
Personally I tend to lean towards our universe being a simulation.
The reasoning behind my thinking, is that our universe seems to have a frame-rate. When we look at smaller and smaller increments of time, there comes a point where instead of fading to the next moment, time takes a jump to the next frame. That frame-rate is the energy state of electrons.
Electrons dont smoothly transition from one state of energy to the next. They make a leap to the next state without any transitioning.
I believe that if the universe were not a simulation, all time transitions would be infinitely smooth no matter how closely we look.
In the end though it really doesn’t matter, does it? Simulation or not, the universe is real enough for all within it.
Let me know what you think,
