Is it possible that our universe is a computer simulation?
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:
What is out there?
Physicists have long studied the nature of the universe, but some theorists are more interested in understanding the unknown (and perhaps unknowable) realm of what matter is beyond the boundaries of the universe. Could there be other matter out there? The answer is: probably. Here are five theories about the possible existence of "something."
What existed before the Big Bang? 1
General relativity -- the theory of general relativity from which George Lemaitre came up with the Big Bang in 1927, as it wasn't then known -- states that time and space are not independent but one. So it's easy to conclude that space doesn't exist and time doesn't (which is, of course, hard to understand). In that sense the above question is a bit like asking "What lies north of the Arctic?" .
The nature and significance of the Napoleonic Wars
The Napoleonic Wars were part of the French Revolution and the continuation and development of the French Revolution in the European continent. The Napoleonic wars in the first half belonged to the siege against the feudal political forces in Europe, while the Napoleonic wars in the later period were the expansion of Napoleon's personal ambition.
The cradle of Renaissance art
Rouen was one of the largest and most prosperous cities in Medieval Europe. There are many famous people in history. The author of the novel Madame Bovary, flaubert, the world-famous great writer, was born here. Rouen is the capital of Normandy, only one or two hours' drive from Paris. It is a famous city with a history of one thousand years. There are many historic sites, which witness the history of France, and it is a beautiful city described by many famous authors. The famous Rouen Cathedral is an amazing sight, attracting visitors from all over the world with its stunning combination of grandeur and refinement, its stunning towering spires and asymmetrical towers. In order to capture this beautiful picture, monet lived opposite the church for a period of time and painted the beautiful church in different colors at different times. The stones of the cathedral change colors as the sun shines, the stained glass sparkles, and this beautiful cathedral is the cradle of Impressionist art.
French cuisine, the French Revolution and the history of France's famous chefs
French food is cooked by cranky French chefs who are very fussy about their food, and these French chefs put too much sauce into their food, plus the preparation of the food has to be perfect. Today, however, preferences are more about taste and texture. Today's French chefs create dishes that have artistic arrangements on plates and contain a wonderful mix of smells, textures and flavors.
Reveal the stars!
The solar system is centered on the Sun and is a collection of objects bound by the sun's gravity: eight planets, at least 165 known moons, five recognized dwarf planets, and billions of small solar bodies. Star cluster is composed of dozens to millions of stars with a common origin and strong mechanical connection between each other.
