We, humans, are unable to experience the true nature of the universe unfiltered. Our senses and brain can only process a fraction of the world. So we have to use concepts and tools to get to know the true nature of reality. Technological progress has not only expanded our knowledge of the universe but also made us aware of worrying opportunities.

          

In the future, it could be possible to simulate entire universes. But if this is an option

-how can we know that it hasn't happened already?

-What if we are not creators but creations?

- Is it possible that we are not real and do not even know?

If our current understanding of physics is correct, it is impossible to simulate the entire universe with its trillions and trillions of things. But we don't need that anyway. We only need enough universe to deceive the residents of our simulation and believe that they are real. Who needs billions of galaxies? We only need the space that our subjects can explore. The huge universe could only be a flat projection and they would have no way of knowing it.

What about small things like cells or bacteria? We don't really need them. If you use a microscope, what you see can be created immediately. As with atoms, the chair you are sitting on does not need to be simulated with quadrillion atoms. We only need the outermost layer of it, it could be empty inside until you decide to break it open. Your body may feel filled with bubbly things, but it may be empty until you open it. The minimum requirement for our simulation is only the awareness of our virtual people. Our test subjects just have to think that the simulation is real.

Okay, so are we being simulated? Well, maybe, but there are some conditions that need to be met. Obviously, we have no authority on this issue, so please take everything we say with a grain of salt. Based on a modified version of Nick Bostrom's original simulation argument, we have five assumptions for you. If they are true, dear readers, live in a simulation.

Assumption one :

It is possible to simulate awareness! Nobody knows what consciousness is. As an argument, suppose you could create awareness by simulating a brain. Brains are pretty complex. If you count every interaction between synapses as one operation, your brain will run at approximately ten to the seventeen (10 ^ 17) for one hundred million billion operations per second. Let us assume generously that we need ten to twenty (10 ^ 20) operations to simulate a second of human consciousness. But we don't just want to simulate a human being ... We want to simulate all of human history at once so we can jump around. Let's say we want to simulate two hundred billion people with an average lifespan of fifty years.

    A year has thirty million seconds times fifty years times two hundred billion people times ten times twenty (50 M sec x 50 years x 200 B people x 10 ^ 20) operations. So we need a computer that can handle millions, trillions, trillions, trillions of operations per second. More operations than stars in the observable universe. The computer like this is simply impossible. Until it's not.

Assumption two:

    Technological progress will not stop so quickly. If we assume that technological progress will continue in a similar way as before, there could be cross-galaxy civilizations that will eventually have unlimited computing power. Beings on a technological level that is so advanced that we could hardly distinguish them from gods. A computer that can handle a million trillion, trillion, trillion operations is serious business, but there are actually concepts for computers that can handle it.

    The Matrioshka brain is the theoretical megastructure, made up of billions of parts orbiting a star and feeding on its radiation. A computer of this size would have enough power to simulate thousands, if not millions, of humanities at the same time. Other technologies, such as future high-end quantum computers, can drastically reduce the size, so this may be possible with a structure the size of a city or even smaller. But only if someone is still there to build the computer.

Assumption three :

 Advanced civilizations do not destroy themselves. If there is a point where all civilizations have destroyed themselves, this whole discussion ends here. If you look into space, you can expect a universe full of millions of alien civilizations, but we don't see anyone. The reason could be Great Filters. Large filters are obstacles that life must overcome, such as nuclear war, asteroids, climate change or a black hole generator. If life is inherently self-destructive, there are no simulations.

Assumption four:

    Advanced civilizations want to do simulations. When we speak of posthuman civilizations, we don't know what we are dealing with, we think we know what beings are as powerful as gods want, they are quite arrogant. Imagine the smartest ant in the world living next to an amusement park. She's curious about what people are up to, so try to explain. Unfortunately, the ant just doesn't understand. The concept of roller coasters and standing in snakes and holidays and fun makes no sense to an ant that leads the life of an ant.

It is the same with us and a posthuman being. We are ants compared to them. Carrying out simulations for fun or for science could be an absurdly stupid idea for them. However, if you want to run simulations for whatever reason and the assumptions one, two, three also apply, the probability that you live in a simulation is not zero.

Assumption five :

   If there are many simulations, you are probably in a simulation. If there are simulated civilizations, it is likely that there are many of them. Finally, we assume that posthuman beings have access to practically unlimited computing power. So if you run simulations, it would be convenient to run millions or even billions of them. If there are billions of simulated universes, there are probably billions and trillions of simulated conscious beings. This would mean that the vast majority of all conscious beings that will ever exist are simulated. For every conscious being made of flesh, there are a billion simulated beings. In this case, since we cannot know whether we are being simulated or not, chances are that you are one of the "nine hundred and ninety-nine million nine hundred and ninety-nine thousand and ninety-nine" (999 999) simulated are fairly high. What you see as reality may not be real at all.

They could really ... be simulated. All of this is based on many assumptions that we cannot really test at the moment, so many scientists disagree with this whole thought experiment. So don't burn your house down to test if there are any malfunctions. If you are being simulated and not changing that much for you, you may be on a small planet accelerated by eternal nothing, or simulating in a computer. Their existence does not become more or less scary and bizarre.

We can only hope to live a good life and have a good time. And I hope that if we actually do simulations in a supercomputer, nobody will trip over the power cable. Read on about paradoxes and thought experiments. Even if theories contradict each other, it is worth it because every experiment was once a theory ...

COVID-19 may offer both challenges and opportunities to IT firms!

The pyramids aren't impressive, the tallest pyramid is over 481 feet tall and was built by a massive labour force who believed their leader to be a God and  The Ryugyong Hotel is located in North Korea where it is stood incomplete for decades this hotel of doom holds the Guinness world record for the tallest unoccupied building in the world and still wasn't built by aliens, the Pyramids of Giza, by comparison, are significantly shorter but still extremely impressive while they're only slightly larger than the bases.

SpaceX's CEO ElonMusk's new Starlink Network project be about to change this blasted off from a Falcon 9 rocket. musk successfully launched the first 60 satellites of thousands that were deployed in the hope to eventually provide low-cost high-performance internet access anywhere in the world, it essentially means rebuilding the Internet but this time in space, so how will Starlink work and when can we expect to benefit from it !?

Elon Musk is working to revolutionizing the internet by building a global communication system that will blanket the world in Wi-Fi. he plans to send a mega constellation of nearly 12,000 satellites into outer space which will orbit above the earth and provide Internet connectivity to the surface below, it could be in a jungle in South America and if you had just an internet link somehow you could you'd have access to all of humanity's information so it actually effectively created a superorganism. it's an ambitious project that will aim to provide Internet to every region of the planet the mega constellation will be broken into two, the first being sent to a slightly higher altitude and compromising a 4409 satellites and the second made up of seven thousand 518it's so ambitious but it essentially means sending up half the satellites of in the next six years in the hope that StarLink will be operating to some capacity by 2020. Before today's launch musk initially tested to SatrLink satellites which had been propelled into space but didn't actually reach operational orbit despite this though must be claimed that the two tests were showing latency low enough to play fast response video games so what do we know about the satellite! well, each one weighs around 385 kilograms and we use lasers to communicate with each other they'll also have an expected lifespan of about 5 years after which time they'll be manually brought out of orbit but you don't need to worry about any space junk dropping out of the sky as the company claims they'll burn up as they return to Earth's atmosphere while satellite internet has been around for a while the ones currently sitting in space at 22,000 miles high over the equator and with the distance that long it's meant connectivity for us Earthlings are unreliable and slow.

I thought the internet would be something that would dramatically affect the future of humanity would be like acquiring a nervous system and where as previously communication would have to occur almost by osmosis and if musk manages to meet his goal the new initiative could give the world internet speeds that around 40 times faster than what we're expecting now and it won't matter whether you're in the middle of a city or deep in monkey jungle but with all this potential for a faster way for the world to communicate it's perhaps no wonder that the competition from rival companies is heating up spacex is so far managed to keep styling technology from its research and development to serious mass production under wraps but the Federal Communications Commission or the FCC has also approved request from the likes of one web Teles at and Amazon to establish big satellite internet constellations of their own, the world has limited to no communications at all and one web is designed it's a big project but one web is designed to bring internet access right to the schools and right to the places in the most rural of environments. high-speed Internet access 50 megabits per second,30 milliseconds latency so it's identical to a cable modem without being constrained having to live in the city the total cost of the starLink initiative is an estimated seven point eight (7.8) billion which will cover the cost of each launch of a falcon 9 rocket but to receive just minor internet connection here on earth spacex would have to send up six more launches of sixty satellites while moderate coverage would mean twelve and while this time the launch took place on a falcon 9 rocket SpaceX also has ambitions of getting its colossal starship rocket ready that could one day take Falcon nines placestar ship was inspired by the 1954adventure of comic book hero and if the spacecraft is ready by 2020 is hoped it may be able to deploy hundreds of StarLink satellites at any one time it's not known yet just how much it will cost people to use the StarLink network but musk has previously said is likely to be a relatively cheap way for three billion people who don't already have internet access to get online but it's not just about connecting everyone on earth as the company also has a more self-serving goal of generating enough cash from Starlink to help fund Musk's lifelong ambition of building a future city on mars a relatively small number of people from earth would want to go but enough would want to go and who can afford the trove that it would happen just weather the company's 12,000satellites StarLink mega constellation will determine the future of Internet remains to be seen so for the time being we'll have to suffer with unreliable internet just a little bit long.
