I want to thank all of you for being so lovable.

I have evidences that go against this BS, we are seeing in the now, now now now now now now, and you can't win the discussion, NEVER

I'm done

and be careful, maybe in YOUR fantasy reality the sunlight will appear 10 minutes before the sun appear in our eyes (morning sunshine), so keep the sunscreens in the pocket, who knows

Maybe I can offer you an object lesson in the manner of people's response.

You are reading it as if people are unable to respond to your cutting argumentation and insightful analysis.... but what's actually happening is that no one can quite grasp how someone with the cognitive capacity to type on a computer or tie their shoelaces could actually consider this anything other than nonsense.

So, enjoy an object lesson where I mystify myself into nonsense.

Water isn't actually wet, because you know... water is comprised of atoms, and atoms aren't wet! That's absurd! If atoms were wet, they'd slip off each other all the time and nothing would stick together. But you can see in front of your very eyes that things do stick together! It's so mystifying!

Yes, and what this has to do with "light travelling through our eyes"

Light has to "travel through our eyes" to reach the retina, where the photons are detected by phototransductive neurons, which starts the vision cascade, leading to an image being formed in the striate cortex - ie, vision.

Our eyes can do it very well without any "photons" (invisible, unproven) having to travel (nanoseconds, or dependending on the distance "minutes") into our eyes to make it happen .. or our eyes do it instantly in the NOW, or It's just that Light does not travel.

Light travels. Get used to it.

What I'm saying is just that, I'm not arguing that what happens in the eyes

Then you believe that we see the sun 8 minutes in the past? hahahaha, this is not even wrong, this is stupid.

visual evidence says otherwise, when the sun appears, it appears in the now .. the sun is not eight minutes in the future, if he was, then the sunlight would appear before the sun appear, which does not happen.
lol . this is totally BS. You can't argue

Oh, yes I can! It takes light 8 minutes to travel from the sun's photosphere to earth. Thus, we see it 8 minutes after it leaves the sun. Your absurd conclusion that the sun would have to be 8 minutes into the future shows only that you need to think more clearly, not that no-one else can argue.

In fact the sun just stopped shining. The end is in 8 minutes. Goodbye friends! :-)

I like the question I heard recently

How fast is the speed of dark?

There's a boring answer to that - see DB's post about the delay between the sun going dark and us being plunged into darkness - it's just the same as the speed of light, I'm afraid.

EDIT: OTOH, if you tried to measure the speed of darkness using a "beam of darkness", you might have a problem!

... And if you do the same thing with a laser beam instead of a shadow, you can show that the speed of light can be much greater than the speed of light!

Far faster than the speed of light!

The problem is that every time we shine a torch on it to measure how fast it moves, it's already bloody gone! :coffee:

Light thinks it travels faster than anything but it is wrong. No matter how fast light travels, it finds the darkness has always got there first, and is waiting for it.

I'm pretty sure dark moves at the speed of light.

Dark is not a thing, it is an absence of a thing, namely light.

It potentially moves far faster. If you had a powerful enough torch to shine a light onto the moon's surface, and used your hand in front of the torch to cast a shadow onto it, then moved your hand so the shadow went from one side of the moon's face to another, the shadow would be moving faster than the speed of light. Factor that up to a torch which is powerful enough to light up the surface of a more distant body, and the speed at which the shadow moves would be correspondingly faster! :naughty2:

Spoilsport! :naughty2:

The thread's OP is the kind of chap that lives in mystification, so I thought my faster-than-light dark would be fitting. The non-mystified answer is that 'dark doesn't travel at all', so of course it doesn't move faster than light, or in fact, anything!

Thommo · **#316** by **Thommo** » Jun 28, 2015 11:07 am

But light is a thing and the light would "travel" behind the darkness at the same "speed"!

kennyc · **#317** by **kennyc** » Jun 28, 2015 11:12 am

I prefer traveling light myself, just a book, a bedroll, and some snacks.

Actually, you can have a shadow appear to move at faster than the speed of light - this is not wrong if carefully said, and it's not a joke - but it is a 'wrong way of thinking' - a mystification, which is why I posted in this thread. The OP seems to wallow in mystification on the few threads of his I've seen!

A shadow is not a thing - that's all that matters really. You can hardly be measuring the speed, or any other dimension of a non-existent thing. All you could be measuring is the absence of light, which makes the mystifying obfuscation go away.

The speed of dark is greater than the speed of light. It's explained by the Theory of Dark Suckers.

https://astro.uni-bonn.de/~dfischer/dark_sucker_2.html

Dark is faster than light. If you would open a drawer very slowly, you will notice that the light goes into the drawer. (You can see this happen.) You cannot see the dark leave the drawer. Continue to open the drawer and light will continue to enter the drawer; however, you will not see any dark leave the drawer. Therefore, dark is faster than light. Go into a closet, close the door, and turn off the dark sucker. Have a friend open the door about 1 inch. Your friend will not see any dark leave the closet, nor will you. Have your friend open the door until half the closet is dark and half is light. Since 2 objects cannot occupy the same space at the same time, and you do not feel any change in pressure, by compressing the dark, it is logical to assume that dark is faster than light.
