I love that. "We have plenty of ways... you're just too lazy to do it."
Name one.
Hell, name all of them.
There are so many it would be virtually impossible to name all of them.
One simple method would be using highly precise electronics with a very long spool of fibre optic cable.
Send a light pulse along it and measure how long it takes to get the signal back.
If light travels instantaneously, there would be no delay.
Another option would be one of the earlier methods:
Find a nice large open area, you could even go across a small lake.
On one side, you have a light shining up into a mirror to go towards the other side, right after the mirror there is a rotating plate with holes cut out. Then across the other side, there is another mirror to reflect the light back and back through the same plate but through another slit, where you then have an eye-piece to view it.
With the plate stationary, you can see the light through the eye-piece.
But when you start spinning it, your ability to see the light depends on the speed of the disc.
If light travelled instantaneously you would be able to see it every time the disc lined up. But because it isn't, you need the slight to line up with the light coming back after passing through the first slit.
But varying the rotational speed of the disc you can determine the speed of light.
You have things like diffraction gratings, which cause light to change direction, with different colours being diffracted by different amounts, which again relies upon the speed of light and the wavelength of light. Refraction is similar. Both of these make absolutely no sense with light being instantaneous.
You are just spouting delusional BS to pretend there is a problem.
And what makes it even more pathetic, is that this doesn't help you at all.
For what we are discussing, who cares if light is instantaneous or not? Having it instant doesn't magically bring things closer.
It doesn't magically explain why the sun sets.
It doesn't magically explain how the sun could ever possibly illuminate a cloud from below when it is above.
It doesn't magically explain how the sun could ever rise due east on the equinox instead of north east like your garbage indicates it should.
It doesn't magically explain how a sun, which is to the north of you, could ever rise south of east.
It doesn't help your BS at all.
Your BS model remains refuted BS, regardless of if light is instantaneous or not; and the RE model remains working just fine.
It is just an absolutely pathetic deflection from a pathetic individual who can't justify or defend their delusional BS.
Meanwhile, the speed of light was not discovered, it was decided. They explain the origin of the speed of light, and how they know it's exact.
You have had that lie refuted before. Why repeat it?
The speed of light was measured.
Then to stop having a metal bar in a vault in France be the definition of the metre, they switched it around, so now the speed of light is the definition of the metre.
This allows any lab with the right equipment to use light to determine the length of a m.
This still relies upon the speed of light actually being that speed.
If the speed of light was different, then all lengths would be different.
e.g. if the speed of light was double what it actually is, then all rulers would need to double in length to remain accurate.
How do I know that? Because in animation
How do I know you are spouting pure BS?
Because you keep pretending life is a video game with all the same limitations of it.
A parallax is a screen both in reality and a video game.
No.
In reality, parallax is the change in angle to an object in the distance due to a distance between observation points.
e.g. if you have a house that is 100 m wide, and you look towards a mountain n the distance, you can have the parallax as the change in angle between the 2 view points.
And importantly, the further away something is, the smaller that angle.
It has nothing to do with screens.
Parallax in games, is about recreating that.
Old games did it with different layers that moved at different speeds; to recreate that key fact above, that the further away something is, the smaller the parallax angle.
Modern games do it by rendering in 3D.
"It would be if latency was variable." I'm sure when you talk like that around your parents or in a classroom, people tell you how brilliant you sound. But it's unlikely to impress me.
Nothing intelligent would ever impress you.
Instead, you are impressed by stupidity and lies like those of your cult leader.
But notice how you again appeal to complete crap, with no response to what I have said?
Do you even understand what latency is and what it would mean?
It is a time delay between the message being sent and the message being received.
Considering you only seem to understand games, lets say you are playing a game, and someone far away is playing with you, and you are the host.
In this particular part of a game, you just need to run down a corridor, as soon as a light goes green at the end.
Now lets assume there is a fixed latency of 1 second between you. i.e. all the messages (including the internal messages of the game to send things like position) you send will take 1 second to reach them and the ones they send will take 1 second to reach you.
You decide to spectate them in this corridor.
You see the light go green, but they just stay there waiting.
That is because they haven't seen it yet, it is still on the way.
Then 1 second, they see it and start moving. But you don't see that yet, because it takes 1 s for that message that they are moving to reach you.
Then 1 second later you seem them walk the corridor just like normal and reach the end.
You see what they are doing 1 second later. But it remains smooth.
Now lets say the latency varies, i.e. it is not a constant 1 second.
So now lets say the latency starts off as 0.1 second. So they start moving 0.2 seconds after the light goes on, but then latency increases to 1 second, so they appear to pause for almost a second and then start moving again, then the latency drops to 0.1 second again, and they appear to jump forward a bunch, as if they moved that 0.9 s distance in 0 seconds.
What you are appealing to is the effect of latency varying.
So it doesn't apply to something like the speed of light at a near constant distance.
i.e. you are spouting pure BS to pretend there is a problem when there is none.
Latency has certain rules. If I play a game that I know will lag my older computer
Except that isn't latency, not the kind that is important here.
That is your computer taking too long to process things.
e.g. if you are meant to be able to do all the math for it in a 30th of a second, but your crappy computer takes a 20th of a second, meaning you can only get 20 fps.
That has nothign at all to do with the speed of light and is not comparable to it in any way.
