Consciousness is not part of the observer effect (which is itself named in the most infuriating way possible, specifically because it makes people think that the universe is somehow aware of when something sentient is looking at it). “Observing” a particle requires interacting with it in such a way that you meaningfully affect its current state of being, whether that be deflecting it in a different direction than it was going or changing its velocity, and therefore it is impossible at a quantum level to be a passive observer that does not influence the outcome.
In the case of the double slit experiment, if unobserved light will act as a wave with interference and if observed then it acts like a particle. The reason for this is both complicated and simple: light behaves as a wave due to probability. There’s no way of observing a photon without influencing it, so therefore the best we can do is say it has a certain probability of being in this collection of spaces, which in the case of photons is a wave (because it can travel in any of a number of directions outwards from the photon emitter in the experiment, but all going away from the emitter and towards the wall the slits are cut into). For the purposes of this probability wave, the start position is the emitter and the end position is the wall behind the slits, so averaging out a large number of photons will recreate the interference pattern on the wall.
However, if you observe the photons at the slits to try and figure out which slits they’re going through you have influenced the photons and thus collapsed that probability wave into a particle, and in the process created a new probability wave from that moment onwards which has the same end position as the original wave, but now starts at the individual slit. From its perspective, there is no second slit, so now the wave acts as if it is in the single slit setup because from its perspective it is, hence the loss of interference.
Nothing here has anything to do with consciousness. You can recreate this experiment with no one in the room and it will behave exactly the same, and has a sound (if very confusing conventionally) mathematical cause.
On a side note, string theory is effectively unfalsifiable and therefore completely useless as a scientific theory.

Consciousness has literally nothing to do with it. In fact, the experiment as demonstrated in this emem would not replicate the double slit results. What has to happen is something along the path has to interfere with the photon (aka observe, which has nothing to do with consciousness, rather just an interaction), which causes the waveform to collapse. Basically, if something needs to know the state, the state collapses into one result. It doesn’t matter what that thing is.

Idk that would depend on what you believe is fundamental lol Fringe science baby!

Yeah, except we can do this experiment without ant consciousness aware of it even and it gets the same results. The only thing that matters is if the particle has to interact with something, because when it does it becomes a specific particle rather than a waveform. What that interaction is with does not effect the experiment in the slightest. A consciousness does not have any effect on the results of the experiment so there’s no reason to expect that the universe cares about consciousness. To the universe, consciousness is yet just another series of interaction of things that behave the same as anything else, except it happens in a pattern that we think of as thought.

Ok but how do you actually remove consciousness from the experiment?

Perhaps the particle is simply moving so fast that it appears as a wave but once it smacks into something it slows down enough to be observed
Btw I do not know any significances about this subject
