since a light "light" is a form of xray how can one take light and make it heavier please respond ASAP
-
add 2 45 pound plates to each photon.

You are talking about two different definitions of the term light. There is light as in the weight of heft of something and their is light as in rays from the sun or a light bulb....two very different things, same word. There are several other definitions for the word light all with very different meanings. This is good example of why the English language is considered a difficult one to learn....the same word means many different things.

JF, Once again you are rushing along the edges of Quantum Mechanics, but in this case, you may be way off base.
What have you read that made you ask this question?
-
Slow it down

Slow it down
how? the prism gives us indigo and other colors presumably slower
you see thats just it. the speed of light is constant anything of different speed is not white light
the different rays are slower if i recall
-

It's possible to slow the speed of light. Physicists have done so in the lab.

yah but they admitted its not light
An entirely new state of matter, first observed four years ago, has made this possible. When atoms become packed super-closely together at super-low temperatures and super-high vacuum, they lose their identity as individual particles and act like a single super- atom with characteristics similar to a laser.

You earn some respect today, Mr. Falcon!

A good question do weight plates get heavier or lighter over time with rust accumulation?

Dont confuse speed with wavelength. Speed is related to the density/tension of the medium a wave propogates in, wavelength is less correlated with both.
Besides, it really has nothing to do with either. It is due to enegy and a consequence if interaction we call "mass."
In the end, the mathematics describes what happens. We can dislike that there aren't more specific words to describe what happens, but the mathematics describes it to almost arbitrary accuracy...so it ends up being sort of like wondering why "crash boom huuummmm" doesnt properly describe a symphony.

No, that's not what they admitted. Let's take a step back: when you freeze water into ice, you still have water. The water is simply in a different phase than it was before. Similarly, the light in these experiments was simply converted into a different phase.

Yes, this "entirely new state of matter" was a Bose-Einstein condensate. The mechanics of the experiment are pretty interesting and very very cool, from the relatively simple and basic physics of interface (http://en.wikipedia.org/wiki/Interface_(chemistry)) interactions and group velocity, to the cooler bits involving optical and magnetic constriction, collimation and cooling.

We were once working on a movie script about what would happen if the speed of light was reduced to 35 mph without realizing that these guys are working to reduce it to 38 mph.
We put it aside because no one could think of what would actually happen if it was limited to 35 mph.
Maybe these guys can give us some idea of how that speed reduction would affect everyday life.
JF and you other smart GetBiggers who have been contributing ot this weird but interesting discussion ..... we may have to hire you all as consultants if this project ever gets finalized for the big screen.
I sure as hell wish you'd all read DANCING WU LI MASTERS so that we could have a semi-intelligent discussion of Quantum Mechanics.
I honestly think that is what JF is sort of "thinking around about" but has not quite gotten it yet.
But don't hold your breath waiting for that phone call.

Excellent post!

By "working on a movie script" you mean, "thought about it for 15 minutes"?

Thank you, doison and avxo for adding your knowledge.

My big question at this precise moment of time is WHY is the Speed of Light set at 186,000 miles a second or 700 million miles an hour.
How was that 'speed limit' determined?

How is any velocity determined except for in reference to another object?
-
WEE LADDY, Actually a bit more than 15 minutes but no one had the attention span nor the 'smarts' to come up with any interesting ideas that would be of any real interest on a movie screen.
DODSON .... "How is any velocity determined except for in reference to another object?" That's another interesting topic within QM.
I seem to recall that the 'other object' had to be 'stationary' to determine another object's velocity, but apparently nothing is stationary within our universe. Not educated enough to grasp it thoroughly but I think that was part of the Theory of Relativity .... something about two trains passing each other.
I are stupid when it comes to this 'stuff' but I did have the opportunity to talk about QM with a UC Physics Professor who told me that I understood it pretty damn well and enough to discuss it with some degree of intelligence.
But if you asked me to explain it, IU'd have to refer you to Dancing Wu Li Masters which I've read about 7 times cause the first 6 times I was completely "dumbed out".
JF, this stuff that you are 'wondering' about is not a rare occurance among the scientificate community and has resulted in major scientific discoveries/advances in the past couple of hundred years.
SO I gotta encourage you to keep on "wondering" about what most of us consider to be 'crazy shit'.
I believe Einstein stated that in more elaborate terms but I think I said it more clearly.

you see the same can be said for light, you put it in a different state of matter its still light but like water to ice........it could be light to something else that doesnt look much like light
water does not look 'that' much like ice
point is all matter IS light just various densities giving us different matter *water like ice* *light like everything*
-

No - the difference in color is because of the wave length and not the speed - the speed is constant for a particular medium.

Right, and?

Uhm... no "matter" isn't light. What we think of as matter is composed of fermions. Light, on the other hand, is composed of bosons. Apples. Oranges.

yes i said the speed was constant bro look what you quoted from me
wavelength is compression or decompression

You clearly know very little about science, so let's see if we can maybe answer in a way that you can understand: Calling a plantain a banana won't make it a banana.

The light does slow down in different mediums however - sorry your post was unclear.

color doesnt even exist, our brain inteprets sound and form into colors
what really exists is form and sound
as for matter a ray of light is so decompressed it seemingly has no matter
-

No, our brains interpret the wavelength of electromagnetic radiation, as perceived through the rods and cones in our eyes, as different colors. Color exists in the sense that it's how we perceive the gradations of the visible portion of the light spectrum.

Yes... "form" and "sound". ???

You showcase the intelligence of a flash-frozen turkey. You use words but say nothing; you just mumble incoherent sentences about random topics the way a monkey flings shit in random directions.

Light has energy/momentum (E=pc) but no mass. If it had mass it could not travel at the "speed of light." Since it travels at the speed of light, it cannot have mass.
The "rest energy" equation E=mc^2 is just the first term in an infinite taylor series expansion. If you consider the classical form of momentum (p=mv) and take the velocity to be the speed of light (v=c), then E=pc becomes E=mc^c, or the "rest energy" of light...where it is "at rest" when it travels at the speed of light.

Sounds right. Actually, seems like you are much more knowledgeable than I am (and certain other folks) about these topics. I am duly impressed.

its difficult to agree with you on that "lights energy has no mass". but i guess you are saying light is purely projection from its source thats why it has no mass.
like looking at a person from a distance that persons mass or brightness doesnt have a mass but quantamly they say it does from entaglement. ehhhh but thanks for writing that i will consider this for many days for a new understanding

Entaglement = entanglement.
Quantamly = quamtumly

By definition, anything with mass cannot travel at the speed of light and anything without mass must travel at the speed of light.
Light is affected by gravity, but that doesnt mean it has mass. It is because gravity affects the manifold with which "stuff happens." This requires general relativity for an explanation of gravity. Light is described by quantum mechanics. Relativistic quantum m echanics (and uktimately QED) is the closest science has come to combining the two but it is only valid in inertial frames. A fully relativistic description of the quantum world has yet to be developed.
Regardless, the "classical" view of physics (where conceptual understanding and intuition tends to hold up better) fails to properly describe both (which is why both of the newer theories were needed).
The universe is best described mathematically. Math properly describes the world and accurately predicts future events time and time again when conceptual understanding fails.
For relativity this means tensor analysis and differential geometry in Einstein's day and differential forms and calculus on rigorously defined "manifolds" in modern appriaches.
For quantum mechanics this means wave mechanics or matrix mechanics and eigenvalue solutions of "operators" (and tensor analysis in relativistic descriptions...which is really just a more general form of vector analysis).
Once quantum computing becomes viable (or if traditional computing power gets high enough) then numerical analysis for both theories will probably lead to the biggest advances in the theories in their current form (computational physics is already the only real way of solving actual problems with any complexity).
It can be frustrating that math is what ends up describing the world...and everyone would love if that werent the case (look up Roger Penrose...he develops some really innovative ways of looking at things non-mathematically...similar to what Feynman diagrams did, but for relativity), but mathematics continues to be the best description of "how things work."

Oh no! This is a big problem, because if any one person disagrees the theory of relativity collapses (that's why it's called the theory of relativity... it's relative; if you believe it is true). I urge you, strongly, to believe, otherwise there's a ripple in the space-time continuum that will make Wiggs' predictions about the coming doom true.
But in all seriousness. You find it difficult to agree? Really? Your agreement isn't necessary, and your inability to grasp relatively simple concepts of physics is not a problem as long as you avoid talking about physics.
