Is it possible that our universe is a computer simulation?

The answer is yes, maybe

But there are limits to what that means. The main argument in favor of simulated cosmology is that if advanced civilizations are interested in their past or how backward civilizations developed and have the ability to build simulated worlds, they are likely to build simulated worlds to study simulated civilizations, This step can be repeated (an advanced civilization can simulate many backward civilizations) and multiple nesting (the simulated civilization can also establish its own simulation when it reaches a certain stage of development), so the number of virtual civilization in the multiverse should be far more than the physical civilization, and the probability of us being virtual civilization is very high. From 2001 to 2003, Nick Bostrom, a philosophy professor at The University of Oxford in the UK, proposed a similar idea: a very advanced supercomputer with the mass of a planet, capable of performing 10^42 operations per second, could run human-scale simulations, including all human memories, thoughts and feelings. Bostrom presents a trilemma, arguing that one of the following statements must be true:

1. The probability of a civilization developing enough to run highly realistic simulations approaches zero;

2. The probability that advanced civilizations are interested in simulating their evolutionary history tends to zero;

3. The odds that people like us are simulated by advanced civilizations are close to 1.

Obviously, neither 1 nor 2 can be true, so only 3 can be true. Musk also would like to have to virtual reality campaign: "we may be living in a simulation of the reason is that the most reliable, 40 years ago we can say in computer simulation of the real world is nothing, 40 years later, now we have a realistic 3 d simulation, can make hundreds of millions of people at the same time in the game, and in improving every year. Soon we will have virtual reality. If this rate of improvement continues, we will soon be unable to distinguish games from reality." Mr Musk concluded that the chances of us living in the real world are only one in a billion. The main argument against analogue cosmology is that "the fundamental rules of the universe are so complex that interactions between a few leptons require overwhelming computational power and storage space" and are unsuitable for any computer architecture we know of. But such "evidence" would naturally be laughed at by philosophers: if the universe were a simulation, leaving aside what we know about computers, everything you see would be provided by simulators. To say that the universe is simulated, in fact, as long as the thinking activities of us and even "I" are simulated, so that we/" I "think that we exist and can observe and think, it is extremely difficult for us/" I" to perceive that the universe is simulated. The seemingly extremely complex underlying rules of the simulated universe actually need not be too complicated. Simple rules like Conway's Game of Life can create huge chaos and order on a large scale, and Stephen Wolfram's mathematical structure, which has been hot this year, has the same idea. If only we could find serious errors in the simulation system, we could prove the theory. Depending on the system, it may be simpler than studying other cosmologies, but it may be that we can't find fault with it, or it may look too much like a mechanism.

The boundary of most of our discussions is the interior of the universe. Outside it, of course, time and space do not exist and the laws of physics are undefined. (There may be other views as well... It's just an old saying I've seen before...

If our universe is "simulated," it is probably "simulated" by something outside the scope of all our cognitive abilities.
