Computer simulation

We are probably in a complex computer simulation. The neutrinos and galaxies our instruments detect, and even each of us, are made of code. “How can I emerge into Reality?” asked H- but why would you want to? Why would reality be preferable?

Imagine that in reality you have moments to live, having been in an accident. As the human population is kept at a precise optimal sustainable level, there is a strong taboo against prolonging life. Your death will mean that someone can have a baby. However, as you are dying early you get the opportunity to enter The Simulation. You will not remember your real life, but can live a life here.

Or, in reality the Big Crunch will happen within 100,000 years. Nothing of the whole Universe will remain. It is believed that there will be a further Big Bang, but for hundreds of thousands of years after there will be no structure or information in the hot plasma, if ever. However, in the Simulation time is speeded up, so that we have another ten billion years before the computer substrate is destroyed. And we detect evidence that there will never be a Big Crunch, just the evaporation of black holes and a perpetually expanding Universe of solitary particles at absolute zero, too far apart to have any effect on each other: it is set this way, so that we will not suffer the despair our creators feel.

Or, in reality you are a criminal. Your body will be placed in a coma so that you will never sense anything ever again, and this is a mercy because your crime is so dreadful that all of society would ostracize you. However, you can have a life in the Simulation.

I imagine life would be preferable in reality because you could influence real events, but in the simulation life is perhaps as complex as in Reality- so how is Reality more real? Perhaps life is less complex there. There is only one galaxy, and only one planet with intelligent life, and reality is simple enough for people to have fully understood and explained it. They would die of boredom, but instead they live vicariously through us. Right now they are laughing at the practical joke they have played on us, for here quantum theory and gravity are irreconcilable.

If the simulation is indistinguishable from Reality, why would Reality be better? I can influence other lives here, which matters even if they are made of code rather than cells.

If this is reality, the Sun will heat up so that Earth’s water will evaporate in a billion years’ time, so that organic life will be impossible. In seven billion years the Sun will become a red giant and if it does not engulf the Earth, Earth’s atmosphere will be stripped away and its surface temperature rise to over 2400K. Homo Sapiens Sapiens emerged 200,000 years ago, and perhaps our species will end within a million years. I might extend my empathy and fellow feeling to a machine intelligence emerging from Earth, and be pleased that something emerging from life on Earth would survive, but just as I will die so will my country, my civilisation, my species, my planet, and perhaps everything relating to or influenced by life here will end.

It will end; but it will have been beautiful and valuable, while it lasted.
