Consciousness and Special Relativity?

Click For Summary

Discussion Overview

The discussion explores the relationship between consciousness and special relativity, particularly how simultaneous neural events in the brain may relate to conscious thought. Participants examine the implications of neurophysiological activity on the understanding of consciousness, questioning whether these simultaneous events can exist within the constraints of special relativity.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants propose that conscious thought arises from a collection of simultaneous electrochemical reactions in the brain, suggesting a connection between these events.
  • Others challenge the idea that simultaneous events are necessary for thought, questioning the assumption and seeking evidence for it.
  • Some argue that the speed of light limits the interaction between neural events, making the notion of faster-than-light (FTL) communication within the brain implausible.
  • A participant expresses skepticism about the scientific validity of discussions surrounding consciousness, labeling it as pseudoscience and criticizing popular misconceptions.
  • There is a repeated emphasis on the need for a multitude of neural events at any instant for consciousness to exist, which some see as a contradiction with special relativity.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the necessity of simultaneous events for thought, nor on the implications of special relativity for consciousness. Multiple competing views remain, with some asserting the importance of simultaneous events while others question this premise.

Contextual Notes

Participants express varying assumptions about the nature of neural events and their relationship to consciousness, with some relying on common sense reasoning without empirical support. The discussion also reflects differing perspectives on the scientific legitimacy of consciousness as a topic.

fdesilva, how confortable are you with Special and General Relativity?

very well in the past, a bit rusty now but still ok.

Are you seriously suggesting that the brain KNOWS that a photon is coming its way before the photon actually hits the eyes nerve cells? You certainly know that it is a violation of the constancy of light speed in vacuum right? Unless you call for "new age science" I can't see how this experiment is valid unless all the GR physical laws we've been using in the past years are violated at human-like energies.

Hi thanks for you interest

This is not what I am saying.

If you can find the time please answer the following.
1. Given that a change of Shape to a 3 Dimensional object can affect all 3 Dimensions Do you agree a change in shape to a 4 Dimensional object can affect all 4 Dimensions?
2. Do you agree that the universe has 4 Dimensions?
3. If you agree to 2 then Do you agree that the objects that make up the universe is also 4D ?
If you agree with the above then what is happening is simply this, the change in shape caused by the interaction of the eye, Conscioussness and the photons take place in a all 4 Dimensions. That is it effects the past as well as the future of that event.

a thought can not only directly cause a change, but can actually cause a change in the past.
why is this not the same as

So what I am saying is when he sees the photo it changes his past brain activity, which is detectable.
In the first case the world changes initially and then the thought changes later, and in the second case the thought changes initially and then the world changes later. They are exact opposites. Your suggestion that your cited "evidence" showing the second supports your "theory" claiming the first is just obviously wrong.

In the experiment what is observed is a change in neural activity prior to the observation.
The question is how could there be a change prior to observation?
What I am saying is that the observation makes a 4Dimensional change in the brain as such you detect a coincidental change prior to observation.

Its as follows Consider a change of state of the brain over time as A1-> A2-> A3->A4
In a 4 Dimensional change a Change of A3 to say B3 will result in A1->B2->B3->B4
Thus the past (A2 to B2), the present (A3 to B3) and the Future ( A4 to B4 ) due to a single change in the present of A3 to B3.
Hope that clarifies what is to be expected with a 4D Change of shape

Ok I have a very simple explanation for this phenomena. My assumption is that when we are expecting a certain sensory input, it is natural for the brain to anticipate it (ever played soccer and noticed that you close your eyes before the ball actually hits you in the head?), thus the results of that experiment.
This assumes that if the subject has no reason to expect something to happen, you shouldn't observe a brain pattern corresponding to that something. This should be a simple way to test this hypotheses.

That is the explanation I expect to be correct also. Since this data has not been independently replicated (AFAIK) and since MRI in general is notoriously non-quantitative I do not expect that the observation has any real significance.

Me neither. I was just surprised how could someone question GR from this, supposed legit experiment, without proposing a simpler explanation without having to take into account the spacetime fabric.

In most of the subforums you are not allowed to present personal theories at all. So far you have presented three separate personal theories in a single thread. I am sure that is some sort of a forum record.

You first proposed that consciousness violates SR because it requires spacelike connections. Then you changed your mind and proposed that consciousness violates SR because it can directly cause a change in the past. Now you are proposing that consciousness violates SR because it can be changed by events in the future.

I am truly impressed by your ability to come up with new personal theories on the spur of the moment, but I don't particularly feel the need to debate someone who is so capable of debating themselves.

Thank dog I am not the only who noticed this. I was about to delete my account from this forum.

I've been pretty generous with letting this thread go on because, it was my understanding this is based off a published work. However, it has begun to slip and slide into areas that are too speculative for the PF membership to consider and respond to. At this point, I think it is best to bring this to a close.
