Re: Speed of light in hubby's frame
For your math, I did "touch" it. The problem with it is that you don't tell which frame of reference you use and to which frame of reference your results apply. In order to be correct, your math must have some connection to reality. In fact I adressed this point several times already. Your math is wrong by definition if you don't use a reference frame.
The problem, as I've noticed, is that you don't know what a frame of reference is(which is high school physics). For example, if your car is at rest, you would tell me that it's current speed is 0 mph but it would be only true in Earth's inertial frame, not in Solar's. By definition, any object's speed is 0 mph in it's own frame of reference because at any time, it's coordinate will be (0,0,0) in a three dimensional space.
You don't seem to know how we use a reference frame in physics, that's why your math when related to it, will be wrong or incomplete most of the time.

Re: constancy
And if you account for the distance the sensor has traveled since the ligtht was emitted from the rear of the train you will understand why it takes longer than half a year for the beam to reach the front of the train.
The distance the light has to travel has increased, the speed of the beam remains the same.
You will also understand why it takes less time for the beam from the front to reach the sensor in the rear of the train when you account for the distance the sensor in the back of the train has traveled since the beam was emitted from the front of the train.
When we say the speed of light is constant we mean that if you are on the train both light sensors come on at the same time. We measure the distance the light has travelled relative to us (half a light year) the time it takes (half a year) and determine relative speed to be c.
The person on the platform also determines the distance the light has travelled relative to them and for all the reasons you just they get different relative distances but the same relative speed, c
If we did the experiment with bullets, the person on the platform would get different relative speeds for the bullets than the person on the train. The speed of bullets (even bullets that don't slow down (fired in a vacuum)) is not constant in the same way the speed of light is.

Re: black holes?
tesla writes:
Which also would explain the emissions of radiation from black holes, It is trying to loose energy but the electromagnetic field is clogged with too much light, and only high energy, lesser amounts of radiation can be expelled into the clogged currents.
I don't believe there is any observed emission from black holes that needs explaining. The emission is theoretical. And what is this dogged electromagnetic field? Did you skip some steps in your explanation?
Supporting observation:
Water is lighter than air. So air in water is a heavier substance. It collects to itself. (bubbles)
Air at standard temperature and pressure is less dense than water at the same temperature and pressure. I don't see the connection.
If the electromagnetic structure is weight dependent on energy levels (collected photons let’s say) Electrons would be separated from photons until a photon is absorbed, raising the energy level, and the weight.
This makes no sense to me. Perhaps you haven't set things up yet. What is the aggregation of photons and electrons you are describing.

Re: observation:
Space time is curved... Now what? If the space-time is not flat, these calculations might only be appropriate for relatively short distances (close to matter) and we have no ability to test for extreme long distances with absolute certainty.
Space time is curved in the vicinity of matter. We use General Relativity to handle those situations, and the math is much more complex. Where space time is flat, or nearly so, Special Relativity is enough to handle the physics, and the math is more simple.
What if light flew around for a while in some swirl.
Uh...
This is why appearances are so deceiving with light. If light is photons and electrons, they still hold particle behavior, and the photon may well be the basic building block of mass. And it's energy the basic unit for all energy capabilities in mass.
Light is not photons and electrons. Electrons have charge, while light does not. A photon is not the building block of mass. Is this stuff necessary to whatever conclusion you are trying to reach? If so, perhaps it's time to drop it.
Is the assumption suspect, given the behavior we cannot explain?
What assumption?
I'm comfortable with the idea that photons don't swirl around, but perhaps you might be interested in that helical wave theory that belongs to that Gaasenbeek fellow ICANT cited earlier in this thread.

You should've read more on gravitational lensing, as was shown to you in Message 504
quote:
In general relativity, light follows the curvature of spacetime, hence when light passes around a massive object, it is bent. This means that the light from an object on the other side will be bent towards your eye, just like an ordinary lens. Since light always moves at a constant speed, lensing changes the direction of the velocity of the light, but not the magnitude.
FromWikiprdia
What if light flew around for a while in some swirl.
Examine: it would circle an area five times without interference, and then land in your eye. The light recorded an object that you "saw", a billion years ago. And the light is that old...but the actual object is a shorter distance to you than the path the light took. So you guess the object to be a billion light years away, because it took the light one billion years to get to you.
How would it do that?

The Difference Between Bullets and Light
The Speed of Bullets
1. A bullet is fired, it travels at exactly b (Where 'b' is a value for the speed of bullets in a vacuum).
2. A rocket is launched chasing the bullet, it travels at exactly 0.5b
Observation: As far as the rocket is concerned, the bullet is travelling away from it at a speed of 0.5b
The Speed of Light
1. A photon is emitted, it travels at exactly c (Where 'c' is a value for the speed of light in a vacuum).
2. A rocket is launched chasing the photon, it travels at exactly 0.5c
Observation: As far as the rocket is concerned, the photon is travelling away from it at a speed of c
I take it ICANT doesn't agree?
This is reality. It is fact. It has been tested, retested, verified and confirmed many, many times by many different scientists around the world. Disagreeing with this is like saying (as someone else already pointed out) "3 apples + 2 oranges = 5 apples".
Light does not behave as things like bullets and other mundane objects do. Repeated observations of reality show that light behaves under significantly different rules. If you ignore those rules, or think they are unnecessary for reality... you are simply wrong.
If you are okay denying reality, and simply being wrong, then no one will be able to show you the light.

Re: black holes?
I don't believe there is any observed emission from black holes that needs explaining. The emission is theoretical.
Just a moment...
"The rotational energy of a black hole surrounded by a torus is released through several channels. We have determined that a minor fraction of the energy is released in baryon-poor outflows from a differentially rotating open magnetic flux tube, and a major fraction of about /2 is released in gravitational radiation by the torus with angular velocity 0.2 to 0.5 relative to that of the black hole. We associate the energy emitted in baryon-poor outflows with gamma-ray bursts. The remaining fraction is released in torus winds, thermal emissions, and (conceivably) megaelectron-volt neutrino emissions. The emitted gravitational radiation can be detected by gravitational wave experiments and provides a method for identifying Kerr black holes in the Universe."
Air at standard temperature and pressure is less dense than water at the same temperature and pressure. I don't see the connection.
WHY IS MOIST AIR LESS DENSE THAN DRY AIR AT SAME TEMPERATURE
"The amount of water vapor in the air also effects the density. Water vapor is a relatively light gas when compared to diatomic Oxygen and diatomic Nitrogen. Thus, when water vapor increases, the amount of Oxygen and Nitrogen decrease per unit volume and thus density decreases because mass is decreasing.
The two most abundant elements in the troposphere are Oxygen and Nitrogen. Oxygen has an 16 atomic unit mass while Nitrogen has a 14 atomic units mass. Since both these elements are diatomic in the troposphere (O2 and N2), the atomic mass of diatomic Oxygen is 32 and the diatomic mass of Nitrogen is 28.
Water vapor (H2O) is composed of one Oxygen atom and two Hydrogen atoms. Hydrogen is the lightest element at 1 atomic unit while Oxygen is 16 atomic units. Thus the water vapor atom has an atomic mass of 1 + 1 + 16 = 18 atomic units. At 18 atomic units, water vapor is lighter than diatomic Oxygen (32 units) and diatomic Nitrogen (28 units). Thus at a constant temperature, the more water vapor that displaces the other gases, the less dense that air will become."
This makes no sense to me. Perhaps you haven't set things up yet. What is the aggregation of photons and electrons you are describing.
I think I need to take this up with my physics department.

Re: observation:
How would it do that?
The same way a bubble goes down a drain.
I would love to run an experiment in a tub with many drains. And watch the paths of bubbles.
The surface run of bubbles going down a drain can sling shot around the same way bodies near the center of the galaxy will do.
But: To be a true test the bubbles would have to be under the surface of the water, draining into other bubble pools manipulated by current.
The creation of heat (when photons are absorbed) may make the universal model different to bubble and water behavior, but still has some striking similarities.
It is beyond my ability to explain very well. But my Idea is that the electromagnetic spectrum is the water of space-time and that there are currents.
The math is what I lack. If an equation followed circles before landing on mass and correctly matched what relativity would predict, then I could get more excited.
Since that is beyond my current education and abilities, I’ll just have to wait and see what the physics department at APSU, or NASA or someone else has to say that may find the idea potential in some form or fashion.

Hi tesla,
What does this have to do with ICANT's topic?
You realize there is a difference between water vapor and liquid water? What you have provided above has to do with relative humidity, dew point and temperature density, all very important to a pilot, but I just dont see what it has to do with anything being discussed here.
I dont think you understand what you are reading, saying water is less dense than air is ludicrous, and your explanation of why has nothing to do with your statement. Your explanation is talking about water vapor making air less dense.
Please elaborate some in order for us too see where you are trying to go, slow down and think it out.

Re: observation:
Very good, when I am in doubt I always research it well, hell i called the air force just to make sure they use relativistic corrections on gps, they do. They even provided my with lots of good resources to explain it all, ICANT ignored all of it, these people operate the system, I wouldn't guess they are lying?
There are some real smart people here too, its just hard to see where you are going, thanks for trying to provide clarity.

Re: black holes?
What does this have to do with ICANT's topic?
Percy told me to hash this out here.
I dont think you understand what you are reading, saying water is less dense than air is ludicrous,
Then my professors are ludicrous.
http://scidiv.bellevuecollege.edu/bg/moles.html
"To go from moles to mass, multiply the moles by the formula weight of the compound.
Example: 0.50 moles of H2O
Answer: The atomic weight of hydrogen is 1.0079. Oxygen is 15.9994. So the formula weight of H2O is 15.9994 + (2 x 1.0079) = 18.0152g/mol. To get mass of water, multiply moles by formula weight. 0.50 moles x 18.0152g/mol = 9.0076g."
and: DENSITY COMPARISON RIDDLE
"The average atomic weight of air is 28.97 atomic units"
So do the math:
Water: 18.0152g
Air: 28.97

Re: black holes?
You are not defining the state of water, ice, liquid, vapor, 3 separate states. You need to state which one, you cannot think liquid water is less dense than air?

Then why did you write about determing the mass of water and oxygen when the question was about the density?
Density is not weight.
And weight isn't mass.
