One method of determining the speed of light is looking at the radioactive decay of ejecta from supernova. Why? Well because if we say that E=mc^2 which for all accounts works fine for us here on Earth, and look at the decay of various isotopes taking place at large distances from earth. If those decay products produce photons at the correct energy, and do it in multiple steps (most decays give multiple different energies) then you can test the c^2 part.
Observations of Supernova 1987a from memory gives us Cobalt lines, which decrease in intensity as it decays. We can check the rate of the decay, to make sure that the decay rate is the same (local passage of time measurement) and if the local speed of light is lower / higher which would result in different spectral line splittings.
As far as i have read (in the past, and just now over the last hour to refresh) all appears to work fine and point at a speed of light that is the same as we observe here.... soooo that is at least a blob about 168,000 light years away where the speed of light is the same
hmm... but the radioactive decay vary as Earth moves around the Sun so how is it any scale for anything ?
Till we know exactly why this happens, how can we know what rate of decay we have to expect 170K light years away.
So you know the answer, yet you deny it, in spite of all the evidence we've collected in support of relativistic math?

if A moves relative to B 3/4 the speed of light, and C moves 3/4 speed of light relative to B what speed measures A on B ?
I know you will come with time dilatation and length contraction as explanation but this is not true.
Not applicable in this example since you can't add .75c to .75c to get 1.5c like you added 60 and 60 to get 120, but I think you already knew that, so I'm not sure why you answered that way, unless you misread the question. As this hoaxed Feynman quote exposes, you can't add velocities in relativity though it's unfortunate how many people don't get why this is false, and that KrzYma does get it but just doesn't believe experimental evidence.

This isnt complicated no there not moving faster than light. Say we have two cars going in opisit directions at 60 MPH. To passengers in either car thay see the car as moving away from them at 120 MPH. An outside observer see two cars traveling at 60 MPH.
The term "Cosmic rays" is a misnomer, as the true rays are gamma and x-rays. The other "cosmic rays" are actually particles, mostly protons, but also electrons (aka "beta") and Helium nuclei (aka "alpha") among others, so I'm not sure why you excluded those.

True Cosmic rays can affect measurements and even video footage and can be also a source of image artifacts suugesting some otherworldly radiation, which is neither alpa . beta, gamma , x rays or cosmic source radiation.
if escape velocity is the velocity needed to escape a gravitational attraction, like in this tennis ball example, why light can not escape the black hole horizon ? this is the velocity to escape ! it must escape at this velocity. This is the whole meaning of this "escape velocity" light also can not stop at the horizon, it stops first at an infinite distance, like in the tennis ball example. But light has only one velocity, it does not slow down or speed up! if nothing can be faster than light, not even light, and light speed is the escape velocity which means light escapes the black hole horizon, how is it trapped then ??
I had a feeling of deja vu watching that because it sounded very much like another EU presentation by Robitaille, and then Crothers shows a slide citing Robitaille as a source, so I think he probably copied most of these ideas from Robitaille. If this interests you then you may want to watch Robitaille's video posted in another thread, which I commented on in this post.

in this video, there is a lot about Black Hole nonsense ( which I will come back to later)
the rest is about the back ground radiation and how it is even NOT what we was told it is, "the image or proof of Big Bang".
So skip to about 23:15 just for the back ground radiation
I couldnt get that link to work but sounds like it might be the Robitaille video I commented on in the other thread, is it?
here it continues... from a guy who is an expert on MRI ( magnetic resonance imagery )
next if you want, is about the Birkeland Current,

Sorry but this question doesn't even make sense to me, especially that last part asking if light escaped the event horizon how is it trapped? Light doesn't escape from inside the event horizon.

You said this before, but you haven't explained the photoelectric effect with this idea, because you can't and this is how we know this idea is wrong.
every EM wave has the same energy, the only difference is the time this wave is acting on something
Why don't you write a paper on the topic and get it published if all the scientists who think otherwise are wrong? But from what I've seen you may not have the math skills to be calling the work of mainstream science "mathematical confusion".
Uncertainty principle, that is used to explain a lot of things, has no meaning at all, it's just a mathematical confusion.
As expected to be if you squash distance ( line in 3D space ) into a single point with no size
EM wave has length! this "line in space" determine its orientation and speed, those are the reel properties of this wave
squashing it into a point removes all this properties, what you call than Uncertainty principle
if you don't understand what I mean by saying this, there is no way we can continue to talk...

Sorry you lost me, if it's unknown to mainstream science, how do you know about it?
And that reminds me, dragonridr never posted his source about gravitational waves. I asked if the CMB study was the alleged "gravitational wave discovery", and KrzYma also asked about a source but I don't recall seeing it posted.
OK maybe you met the terms and conditions for the above, but you didn't meet them here:
but anyway... before I leave, just some "stuff" to think about, if somebody likes to think, if not, I don't care !

To answer your black hole and light question, I think its said light cant escape because; If we agree that light travels along the path created by the gravity field (meaning that light does not just travel through the vacuum, or no matter how curved gravity field was light would just travel straight...because if the gravity field is everywhere, then that means there is nowhere that is pure vacuum...a vacuum would just mean the averagely least affected gravity field away from massive objects, so light would travel at the speed of light in that free gravity field, but if you take two equal areas of space, point A to point B say they are both 100,000 yards distance between A and B and there was no mass near this area, so the gravity field was quite constant and steady, but then only one of these areas, there was lots of masses added to it, so now one area has pure non mass occupied steady gravity field of distance 100,000 yards. And the other area distance 100,000 yards between A and B has a gravity field that is very curved and distorted. I suppose it is supposed that from A to B in both those trials, the light would take a longer time to get from A to B in the curved gravity version then the lacking mass version. This suggests that the gravity field is the medium light always travels through).
To get back to answering your question; black hole is thought to be a large area, large 3d distance, with lots of curved gravity field, so if you imagine light getting into the middle of a 1000000000 yard 3d area, and that area constantly curving in on itself, at every point within the 3d area, from the center going outward, the light, like a maze, will just be trapped following the curves, instead of finding a path of least resistance out of there, the path of least resistance is for it to be compelled to follow the curve.
Depending on whether or no light itself creates its own gravity, perhaps lots of radiation being created and then trapped in/as a black hole, is what gives it is great mass, and gravitational prowess.

Light doesnt care if space is curved it doesnt effect its speed only its path relative to an outside observer. You seem to be under the impression gravity slows light it doesnt nor can it. Key is if you curve space enough light cant escape a blackhole because space itself curves back in on itself.Gravity warps space it isnt about gravity fields gravity fields are created by space itself being bent. In other words gravity waves arent the cause of space being curved they are an effect when it does.
Gravity curves space doesnt effect light what so ever.
If all photons had the same energy and it was just a question of time interval, then I should see the electrons ejected in the photoelectric effect if I just wait longer, but I don't. why? Because your idea isn't supported by experiment.

I did !! time interval !
So, fix that. Get a PhD in physics, publish your paper and get some people to read it. Don't make a controversial topic your PhD thesis, write that about something non-controversial. It's no guarantee they will listen, because getting a PhD does nothing to prove your ideas are right, but it's some indication you may have enough technical understanding to make your idea worth considering.
because I'm nothing in the eyes of scientific community
nobody will listen !!
OK well dragonridr answered your black hole question, and you might need more math than this to understand the answer mathematically.
I can also add and subtract
That's a common fantasy of new age pseudoscientists to think the observer effect has something to do with consciousness. In fact I made a thread to illustrate how silly that idea is, about the observer effect in cooking my turkey dinner:
and to confuse you, I take apart this experiment...

Inside the event horizon can't be seen.

So you mean an object ie a star or galaxy behind a black hole event horizon cannot be seen?
We have one model of it in general relativity, and we have another model in quantum field theory, and the two models don't talk to each other. As a result both models run into some problems in certain cases. It's an unsolved problem in physics, or in other words, we don't understand it as well as we'd like to. Actually that link contains a series of unsolved problems under the quantum gravity heading, and several are related to our lack of understanding about space-time.
