But, the suggested experiments are missing crucial details.
If you do some studying about quantum mechanics and the experiments that where done in the past, you will see that the terminology of "detectors", "measurement", "observer", "recorder" and "which way data" got a little mixed up when it comes to MBT.
At first I thought that they were "metaphors" for explaining things to non-scientists. I am not sure that this is the case.
This is not true. The experiments are sound, and are in "physics form" in the published paper outlining them. Tom must speak in lay-mans for the interviews and videos but the experiments are most certainly not missing any crucial details.
So, my question is: what does it mean to observe/measure the slit data?
These experiments are pretty simple once you understand the fundamental concepts of how a virtual reality works. Think of the MMO video games we play, like World of Warcraft for instance. They all exist inside a server somewhere, and each person is given their own individual data stream. Nothing really exists in that game, it's all just 0s and 1s which color pixels on your computer screen, and you've learned to interpret those changes colors on your screen as an elf moving, a lake, a mountain etc. But fundamentally, the game is just changing colors on a screen in such a way to make it seem like there is an elf etc. If you are not in a certain zone, or looking at a mountain, it is not rendered. It doesn't exist. The game isn't sending that data to anyone. It's not there. It only exists as a probability. When someone looks at that location in the game, poof! there it is! When they turn around, it's gone! Get into the fundamentals of how games are rendered. Especially have a look at NO MAN'S SKY, which works very similarly to this reality. The answers to your questions about the experiments can all be found there.
So now to try and help you:
A "measurement" is anytime a CONSCIOUSNESS observes something. Unless an actual consciousness observes something, it is not rendered into the reality. In the case of the "delayed erasure." Firstly you must understand there are two different sets of data being collected in every type of double slit experiment. The data of (1) which slit did the particles go through. and (2) what does it look like after the particles went through the slit. Understand this. Read it over again. Two different types of data being collected in each experiment. If we don't collect (1) and just collect (2), diffraction pattern. If we collect (1) and we look at it, when we look at (2) there will be two lines.
The paradox is: Scientists KNOW that when the detectors are on and measuring at the slits, that we see two straight lines behind the slits, NO diffraction pattern. Detectors on = no diffraction pattern. But, if we leave the detectors on, collecting the "which-way" data (the particle went in this slit or that slit), and then we DELETE the data without ever looking at it and BEFORE we look at (2), we get a diffraction pattern. But wait! The detectors were on, it was supposed to be two slits, why would it matter if we deleted the which way data. Because the (1)data was deleted before we looked at 2, it works as though the detectors were never on in the first place. No consciousness had a chance to see it = it doesn't exist in the reality. Just like, if we don't look at the mountain in world of warcraft, it doesn't exist, it is just a potential waiting to be rendered / actualized.
Let me try and explain it again:
Collect data at the slits (1) , look at the slit data(1) , look at the screen(2), the screen (2) shows two lines. [(1) data collect and observed]
Don't collect data at the slits (1), look at the screen (2) , diffraction pattern. [No (1) data collected, never observed]
Collect data at the slits (1), don't look at the slit data but don't delete it , look at the screen (2) it will show two lines. [(1)data collected, not observed yet, but implied, it exists and is waiting to be observed, thus we see two lines as if we look at (2)]
Collect data at the slits (1), don't look at the slit data and delete it THEN look at the screen (2) , diffraction pattern. [The which-way data(1) no longer exists and no consciousness had a chance to observe and actualize it, so even though it was collected, a diffraction pattern will appear on (2)]
Collect data at the slits (1), don't look at the slit data, look at screen (2), two lines, THEN delete the (1) data, look back at the screen (2), STILL two lines!! [This reality must maintain historical consistency, as soon as we look at (2) and see two slits, it will always stay that way, even though we deleted the which way data (1). The order of the operations is important. Historical consistency MUST be maintained.]
There are all the possibilities of the delay erasure experiment that I can think of. Hopefully these explanations will make sense to you. The only logical way to explain these experiments is that we live in a probability based virtual reality, not a deterministic material reality. Because science shows hard evidence we live in a probability based virtual reality, virtual realities cannot render themselves so by logic we exist within a more fundamental parent reality that exists completely outside of this entire universe. This reality is doing the computing. This reality exists within consciousness. We are all consciousness. Thus --> Everything is connected. One large intertwined connected conciousness system. The most profitable way of existing within an intertwined completely connected netted system is cooperation and caring for everything else. Love is the answer. That's how it's all going to fall out eventually. But, will it take 10 years or another 1000, that's up to us collectively!
