Good information and discussion. There is some confusion about the word information. Obviously a photon doesn't carry information the we would think of it. But surely it carries information nonetheless. Or data, or whatever you want to call it to understand it.
When we see a color it is...
I was wondering, well basically if photons carry information about themselves that is interpreted by our brain?
I ask because I was thinking about things like color and distance. Correct me if I'm wrong but we see different colors because of the way the molecules or elements that make up an...
A better question to that last part would be if the photon carries all the wavelengths how do we get one wavelength over another.
What I mean is if we wanted to take an x-ray how do we get the x-ray wavelength to show over the other wavelengths.
Does the photon carry the whole spectrum of light or just the visible wavelengths?
If it only carries the visible spectrum are there other particles for each wavelength?
If it carries all wavelengths then a photon would be carrying gamma rays and x-rays as well right?
And if it carries these...
Ok I looked at the inventory, for some reason I just figured that the amount of photons had to be so high that they would have significant mass. But I guess the fact that it doesn't shows me that I didnt have a very good grasp on how small of a mass a photon actually had.
But with all the stars that have ever existed with all the light that has been emitted over billions of years then shouldn't the universe already be packed with photons.
And if it is packed with photons could it be heating up the universe but the universe is turning that heat into momentum and...
Why is the Higgs so hard to find.
I'm very excited about the research going on at the LHC as I have said before I believe that the LHC is going to give us more answers than we have questions for right now.
The technology is very advanced and powerful and should provide a wealth of information...
Ok this is a difficult question but i'll try to keep it simple and if I say anything that is wrong, if it doesn't change the basis of my question or the answer then just ignore it.
My question is related to particles that are given off by stars, and perhaps other places.
Light is...
I would like to add one more thing.
I thought that gravity was not just a phenomenon related to matter, as I have stated above, but a phenomenon related to the way matter interacts with spacetime.
I forgot to mention my thoughts on the affect gravity has on mass in my line of thinking.
We know gravity is responsible for, well, basically falling. So when I think about this fact in relation to my above statements I would think that the compression lines of gravity work almost like a slide...
I have always thought of gravity as being a phenomenon related to matter.
I have always envisioned it as a "contraction" in spacetime reaching out in all directions from an object.
What I mean by contraction is that the closer you get to a body of mass the more spacetime is compressed.
Due...
Two more questions I just thought of.
Correct me if my assumption is wrong but as the CMB moves further away it cools.? If that is so then if we were to somehow cool the telescope to absolute zero, could we see further into the CMB and see it with more detail?
And two, how does the Planck...
Thanks for the replies guys, or girls, does anyone know how much more accurately the new mission will map the CMB compared to the old images.
Can or do we use spectroscopy on the CMB to obtain information on the elements or particles and the quantity of them that sent the light all those years...
