Title: How much time does it take for an electromagnetic field to enter your eye?
Post by: guest39538 on 08/06/2018 12:41:36
As title question.

The Suns electromagnetic field for example.

Why is it that I can probably guess what you are going to say?  ;)

Ok, here is my take on it:
For something to enter it has to move a distance so knowing that distance and the speed, in this case c, we can calculate the time taken. Question is “what is the distance”? Some might say the thickness of the eye covering, so we are talking about the corneal epithelium andthe precorneal tear film (PCTF).

Before we find out how thick that layer is, can I guess that you are going to suggest a 0 thickness for the threshold hence instantaneous entry, suggesting light travels instantaneously?
OK, I deserve that.

I did not mention light, but now I hope you can understand my notions about light. 

What if electromagnetic radiation was always in your eyes , even with eye lids shut?

Hence no distance at all to travel.

Could that be a possibility when considering entanglement?

I did not mention light,
If you mention eye, and EMR from the sun, folks are going to think you mean light, so you need to be more specific.
Yes, radio waves can enter your eyes with eylids closed, but the eye won’t detect them, and they pass straight through and that takes time. They aren’t there all the time.

I think you should catch up on the research of Ibn al-Haytham (960-1040AD), who had radical ideas about how light enters the eye.
Apparently, he developed his ideas while he was in prison, seeing a light ray entering his prison cell.
He corrected the erroneous ideas of Euclid & Ptolemy which had held sway for over a millennium; these ancient philosophers mistakenly believed that light and vision originated in the eye.

See: https://en.wikipedia.org/wiki/Ibn_al-Haytham#Theory_of_optics

Hint: Light enters the eye even without entanglement.
As for how light interacts with biological molecules like chlorophyll, there are hints that there is some quantum-mechanical weirdness happening there.

Because it is obviously nonsense.

Lol, what about x-rays, gamma rays etc?

It's still nonsense.

So what do you not understand that you keep assuming is nonsense?

Because if you keep declaring it nonsense, we can see quite clearly that you are just pretending not to understand the subject.

Have you conceded to me ?

I understand the subject, so I can see that it is nonsense.
You do not understand it, and so you do not realise that it is nonsense.

There's nothing meaningful for me to concede.

Ok, so you claim to understand the subject, educate me to the topic title and the speed of electromagnetic radiation entering your eyes. You are saying your eye lids stop all lengths of electromagnet radiation passing into your brain functions space.

How is that possible ?

I didn't say that- you made it up.
Please don't do that again- apart from anything else, it makes you look silly.

Hmmmm,  I said gamma rays, x-rays enter your eye, you said nonsense, therefore you did say that unintentionally.  Perhaps you could be a bit more considerate when you post.

No.
You said "

and I said it was nonsense.
It's still nonsense if you talk about entangled gamma rays.

Please try to keep up with what you are saying. You look really silly when you can't even agree with yourself.

How can ''energy'' ever be isolated?  Energy can only be 'isolated' by energy. 

So how can the energy inside of my brain be isolated from anything else?   

I can see an object a distance away , I can see every point of that distance if looking at the ground.  How is that not entangled?

because "entangled" means something else.

Hear we go with science ''legalese'' again, define your version please.

Quite clearly everything I can see is affecting my brain, if it weren't I would not see it. You know like, you move , I can see you move because the picture in my mind moves. That is entanglement sir?

You pushed me to keep learning, don't blame me......

Who should I blame for the fact that you still don't learn?

If you don't know what the word means, don't use it.

Nobody said otherwise.

Not in the scientific sense, nor in any sense you will find in a dictionary.
If you make up random uses for words people will not understand you.
That is your fault, not theirs.

My creator ?

Yourself ?

Myself ?

I am not sure what you want you want me to learn , I am learning I am not getting anywhere in life by being on here, is this what I should learn?

You could start by learning that you shouldn't use words if you don't know what they mean.

You could also learn that it looks silly when you say things that are wrong rather than asking if they are right.

Who is the judge whats wrong and right with the use of words?

You can call an apple an apple but I could call it energy , we see the same picture don't we?
