Star triangle paradox

He needs more time? To come up with an intelligent statement of his position?

::roflmao:
 
John99 tells me he can only reply to threads between 12 am and 6 am, apparently.

I gave him 24 hours, so he should have been able to find 2 minutes somewhere in his 6 hour windoww.

We'll take this up again when he gets back in one week.
 
Welcome back, John99.

You must now either support or retract your claim that you can see a door 3 metres away as it is right now (i.e. without any time delay for light to travel to you from the door).

This is equivalent to the claim that light has infinite speed.

You have 24 hours from the time of this post to respond.

You will now answer the following questions:

1. Is it true that light has a finite speed? Yes/no
YES
2. Does it take light from a door some time to cross the room to your eyes? Yes/no
I am going to say: NO
3. Do you see light coming from a door some time after it was emitted? Yes/no
YES although not with 100% certainty or under ever circumstance...i really cant say for sure.
4. If the speed of light is $$3 \times 10^8$$ m/s and the door is 3 metres away from your eyes, does the light take 10 nanoseconds to reach your eyes? Yes/no
That depends on weather there is other light in between. Could be in the penumbra. I am visulaizing these sources coming from the same direction. I see no issue in the light sources coming only fromn directly above.
Edit: I dont mean the glow of the light phsically reaching an object, in this case eyes. Reflections may be different.
5. Do you withdraw your previous claim that you see the door as it is now and not 10 nanoseconds ago? Yes/no

These are observations.

If you can't see that your answer to question number 2 is in direct contradiction to your answer to question number 1 then there is absolutely no hope for you.

That would be the point of contention.

In other words you're clueless.
If, as you have agreed, light has a finite speed, how then can it NOT take time to reach your eyes from the door?

Post #184 has an edit, it corresponds with this question.

Your edit was done before I posted.
My question stands.

The sentence "These are observations" is incorrect.
At least one of your contentions is false and has not been observed.

Could you please explain how this works?
I'd like to apply the principle to road and air travel: finite speed but zero transit time... I could charge a small fortune for tickets and people would be flocking to buy them.
:rolleyes:

Do you think your vision is moving? In other words, a vision chart is on a slide, it starts at 10 metres away then slides back to 70 meteres and keeps ding that. Is your vision moving?

Irrelevant and specious.
We see because of the light that reaches us from the seen object. That light takes time to arrive from its origin.

And what, exactly, do you mean by my "vision"? My eyes move when I move, therefore my "vision" moves.
"Vision" is not an object, it's a perception. How can a perception "move"?
 
James, how long is this nonsense going to last? It's obvious by now that John99 has no intelligent statements.
 
John99:

Please explain for me the physical process by which you see a door that is 3 metres away from you.

Why is it important to have light? What role does light play in your seeing the door?

Tell me how the image of the door is formed in your eyes. How do your eyes know there is a door 3 metres away?

Make sure you explain in detail, because I'm going to assume you're trolling if you don't explain yourself.
