Physicists have long struggled to explain why the universe started out with conditions suitable for life to evolve. Why do the physical laws and constants take the very specific values that allow stars, planets and ultimately life to develop? The expansive force of the universe, dark energy, for example, is much weaker than theory suggests it should be – allowing matter to clump together rather than being ripped apart.
A common answer is that we live in an infinite multiverse of universes, so we shouldn’t be surprised that at least one universe has turned out as ours. But another is that our universe is a computer simulation, with someone (perhaps an advanced alien species) fine-tuning the conditions.
This leads to the extraordinary possibility that our entire universe might in fact be a computer simulation…
In 2003, philosopher Nick Bostrom from Oxford University in the UK formulated his simulation hypothesis. This argues that it is actually highly probable that we live in a simulation..
Physicist Seth Lloyd from the Massachusetts Institute of Technology in the US took the simulation hypothesis to the next level by suggesting that the entire universe could be a giant quantum computer.
And in 2016, business magnate Elon Musk concluded “We’re most likely in a simulation”…
“In late 1990s Los Angeles, Hannon Fuller (Mueller-Stahl) owns a multibillion-dollar computer enterprise and is the inventor of a newly completed virtual reality (VR) simulated reality of 1937 Los Angeles, filled with Artificial Intelligence unaware they are computer programs…”
