Let us not forget about Pilot-Wave theory, where it has both particle and wave-like properties simultaneously. In fact, I don't quite get why people are so enamored by these fanciful interpretations when Pilot-Wave is so much more down-to-earth.

I came here to say the same thing - this behaviour is readily explained by a pilot wave formulation of QM, and requires no spookiness. Increasing number of physicists are re-evaluating Bohm and De Broglie's work - I for one think we've been down a 60 year dead-end, which has yielded models, but no plausible mechanism.

And perhaps someday we'll get to meet the great programmer in the sky the developed the simulation we are living in and we will ask him why he designed it that way and he will say something like "oh I just wanted to optimize the code so I simply excluded reality subroutines when there were no beings looking. I just never thought you guys would notice. As soon as I saw that you guys noticed the flaw, I was going to lo…

Well, if you want to prove the simulation argument, all you have to do is simulate a reality for an individual at any time-dilation you like. With the parallel compute capabilities we are increasingly growing, simulating a small section of the universe at a large time-dilation should be within our grasp sooner than we think.

So, the Sun doesn't exist when experimenter is unconscious? I see. It seems like at least Philosophy 101 should be mandatory to quantum physicists.) Reality doesn't depend on an observer (who distorts it by his observation). Reality just is. There are light and other temporary states of what we call "energy". That's it. Time, space, relativity are human concepts - the hard-wired modes of perception which conditions o…

Or perhaps quantum physics should be mandatory for Philosophy 101?

In other words, reality is lazily evaluated and is written in Haskell ?

The fastest anything can travel is the speed of light, which is the speed perceived when a result is already calculated and held in a CPU cache. For everything else, it must be loaded from RAM, Disk, Network and perhaps also operated upon - which can never be as fast as the speed of light.

Earlier quoted context omitted.

Not really, most of it is just hacked together with perl: https://xkcd.com/224/

Perl 6 has lazy evaluation, doesn't it?

There is a limit to the total computation that can be done in the universe or with a certain limited energy/volume of space. It's caused by the slowness of signals traveling at light speed. They say probably a black hole is the best computational engine there is.

Which is another way of saying that reality is invented.

"Measuring" is applying our sensors onto the external reality and producing a map of what is observed in the form of thoughts, ideas, imagery - 'perception'.

But since the sensors are also part of reality, which does not exist before sensing it, it can be postulated that what is perceived is not a consequence of reality hitting the sensors, but the result of a new thought about reality being perceived, or simply - an invention.

That is, reality (including your body, brain and you) is the product of a thought process, but (here's the interesting part) the thinker is you and not you at the same time, or rather - the thinker is you and every other being.

That thinker is called God. Or Universe or whatever you want to call the thing or being that is the eternal recursive loop of self-invention / self-perception.

Of course very hard to put into language, but easily grokked under psychedelics.

It's interesting that science (and math) is slowly pointing towards this conclusion too, a thing that many great scientists arrived at intuitively.
