Neil deGrasse Tyson Explains the Simulation Hypothesis

Neil deGrasse Tyson and comic co-host Chuck Nice are here (or are they?) to investigate if we're living in a simulation. We explore the ever-advancing computer power and how that impacts the simulation hypothesis. Chuck wonders if a simulation universe has anything to do with us not being able to travel at the speed of light. You'll learn about Bayesian statistics. Lastly, Neil tells us how he was ready to embrace the simulation hypothesis until he came across a certain idea that changed his mind.

4:45 the problem I have with this solution is that it doesnt factor in the possibility that there is more than one simulation running. What if complete simulations just become integrated into programming class and we're some random kid's final project. My point is, it's more likely for the chain of simulations to be a tree, with several branching paths, rather than a boring straight line.

[@bourneslippy8039]

Yes! I had the same thought, and what if the "real" world(or even higher level simulations) are exponentially more complex than our own? Of course we couldn't comprehend a world that we weren't designed to be in. Or perhaps it functions completely different than our own.

[@punishedexistence]

But that's where the theory of relativity comes into play. Every person displays a simulation of this world onto their own psyche. Every observer is a different relative point but only the one that's computing is the one that matters at that point in time. Think of 8 billion tape recorders all recording at the same time. That's us. But only one tape is played at a time so that is the snapshot any one observer is limited to. Sure, you can play all 8 billion at once but then the result is facebook...

[@Ashblossomm]

​@@punishedexistencewell you think of humans as the center of the universe or in this case the simulation we're only observing with our own eyes to our own mind the simulation is running with or without humans the ones looking at the simulation they don't look at it from humans perspective they just look at the whole picture and receive data

i ve been defending this hypothesis for almost 5 years it goes even beyond that, since myself im programmer. its said that the planck lenght is also some limiter and its a number so unique it has to be set, so its the fibbonacci, also the more you study the more you see that most things that jesus said or that christians belief, like things are set by god, if you changed god by a programmer it will even makes way more sense. so both of these things can intertwine into one, so beautiful. there is so many things that opens your mind, after you think like a programmer rather than a physicist. or a mix of both

[@Broadsmile1987]

​@@DarkWing494 You don't need a perfect simulation. We may live in an imperfect simulation, but haven't realized it yet. Some limits like causality speed or maybe some resolution (elementary particles or their alignment to grid or smallest quantities of time: Planck time etc.) or some optimizations (like the particle-wave duality) may be hints that we live in the simulation. Or maybe the reality is just odd. If we can discover exploits like perpetuum mobile, it will be a strong evidence for us living in a simulation IMHO. Considering the fact our universe is odd, it suggests if we live in a simulation, it wasn't designed in the way to seem realistic to us - hypothetically you could create a simulation, which seems more realistic than reality (kind of like ancient Greeks were building skewed columns, so that they seem straight from far away). In the end of the day, we already can drug someone to decrease his perception and analytic capabilities, then put VR goggles and earphones on him and he will confuse this experience with reality. Similarly, we might be drugged or otherwise significantly less mentally capable right now, and the creators of this simulation could have created a very simplified version of reality - but because we don't know/remember the reality, it seems to us our environment is complex beyond possibility to reproduce it in a simulation.

God interrupts them and says ‘wait, start with your own dust particles.’ It is not true just a story to help you understand. The laws of science says you can’t make something out of nothing.

When you die you can either play another game (if you have saved enough the one with superpowers :)), or you can choose reality. Or it might be a training tool. As soon as people turn 4 they get connected to the simulation, where time might run faster, so that you can experience a whole life and learn all lessons, within a day, and when you are disconnected, you are a person with the experience of a lifetime. Obviously, if you were unable to learn the required lessons, you have to do the whole thing again. And again. And again. Until you have finally reached the necessary maturity to live in the real world (which might be one where everybody has superpowers.

I think the second argument that we are either the real universe or the one that can't simulate universes yet is not a good one. All you need is a single species jn the entire universe to he able to simulate a universe in order for the chain to continue. Just because we can't simulate a universe doesn't mean we are the final chain in the sinulation-verse. Also, maybe the simulations each universe makes is way less detailed than their parent universe. So maybe we have already continued the universe chain when we made Minecraft, or GTA, or whatever. Just because those games are way less detailed than our universe doesn't mean they aren't universes. Maybe our universe is just a very simplistic game to our parent-universe. Here's a cookie if you read all the way to the end 🍪

I don’t like the argument they made because it’s implying that there is only one “real universe” or the “base universe” that is the start to all the simulated universes. By implying there is a non simulated universe there must be another way to as how it got there. Using this logic we cannot assume that only one “real” universe was created. There could be an infinite amount of real universes making the probability of us being in a simulation change drastically. Especially depending on when these base universes were created

Striking intention so it can be run on specific kind of computer device, which is digital computer 3. It has distinct smallest unit of measures, not indefinately smaller. Similar to pixel in digital computer. 4. It has efficient rendering technique. Which is only render things when it being observed by the player. Once player is not observing, it going back to code and algorithm without need to be materialized 5. It has universal 'server tick' to synchronize everything and to avoid inconsistency around the simulated world. which is speed of light. 6. Since space and time are the output of algorithm, Anything unrelated to wolrd rendering algorithm, are not bound with space and time and can communicate instantly since it run outside the rendering algorithm. Such as quantum entanglement 7. Since almost everything is centered around the player, and almost everything is being rendered as per the player pbservation, not only future, but also any past time event is still on a form of code, and being rendered once the player is observing it. Thus, quantum delayed choice was happened 8. When the player dies, it could goes to spectator mode. Since the player viewport is not necessarily hard coded to the rendered body. 9. The player could go to different realm or mini games during sleep 10. There are millions of account and eyewitness, testimoning about them being experiencing some kind of glitches in the matrix 11. There are literal source code of higher level programming language, written and stored in every living things. That when compiled and run, it will create chemical nano machine that run autonomously based on previously written code. 12.

[@xIPatchy]

Scott Merts because we are talking about a level of infinity, aka an infinite loop of stacking simulations, multiplied by another level of infinity, the possibility of every simulation branching into multiple simulations, the likelihood of being inside of a simulation that is either an endpoint or the beginning is still the same, because while you are adding an infinite number of possible endpoints in your argument, you are actually creating a higher level of infinity at the same time, and cancelling it all out.
