No he does not. He says that, given some conditions, it is very likely, but he does not claim that those conditions are very likely.Tyson Says It's 'Very Likely' The Universe Is a Simulation
I don't see how. But I didn't see how to test the EPR paradox either.If the simulation was run using spacetime as the computational medium could we tell the difference?
I don't see how it is possible to rule out that it is an experiment. Somehow you'd have to show that this leads to a contradiction, and that seems impossible to do.Is it conceivable that we might one day say the universe is definitely not a simulation, but we can't rule out that it is an experiment?
That's not really true, start at 1:38:00, his exact words were: "I think the likelihood may be very high, and my evidence for it is just: it's a thought experiment." He didn't come right out and say he thought it was likely, but he alluded to it. I think of it as a misstatement during an off-the-cuff remark rather than being interpreted incorrectly.No he does not. He says that, given some conditions, it is very likely, but he does not claim that those conditions are very likely.
It's like saying "if a big asteroid hits New York city tomorrow, the city will probably get destroyed". This is true - but it does not imply a large probability that New York city gets destroyed tomorrow, because the asteroid impact itself is very unlikely.
