    Gravity & State of Matter: Does Force Vary?

    Since we are just speculating here, why not simplify the system and keep Occum happy.:smile: Instead of photons emitting gravitons, why not look to the photon itself. Consider the photon to be composed of electric and magnetic fields. The fields reach saturation amplitude at points moving along...

    How does a DC current polarize

    An AC current when coiled around a magnetic capable material continually switches poles with each repeating cycle. This disrupts the magnetizing process. A DC current keeps the same polarity so that the material can align its atoms and so take on the magnetic property.

    Is this how particles interact?

    What would you consider an alpha particle to be? :smile: Oops: alpha particles are two protons and two neutrons; my mistake!

    Is Physics Nearing Its End or Just Beginning?

    As an old engineer, I am biased, but if it is advice you're looking for, I would say learn as much physics as you can then apply it in the field of engineering. We get paid more than the researchers, but I imagine they have more fun :smile:

    Does gravity affect gravity the way gravity affects time?

    Time is part of the equation for gravitational acceleration. Gravitational acceleration determines the rate at which galactic stellar objects rotate. It seems that calculations about the rotation rate of these stellar objects should need adjustment to account for time dilation as a result of the...

    Does gravity affect gravity the way gravity affects time?

    Yes; I have Googled and searched, the puzzle I am left with is that it seems that gravitational force should affect the amount of gravitational force an object can produce. I view the fact that time is part of the equation for gravitational acceleration as a clue that this may be so. Then I...

    Does gravity affect gravity the way gravity affects time?

    But wouldn't an inside observer see the time of an outside observer speeding up relative to his own? This is different from relative speed where each observer sees the others time as slowed.

    Does gravity affect gravity the way gravity affects time?

    An object in a gravity field experiences time more slowly. I was wondering what effect this would have on the ability of a black hole to form. It seems that the slowing of time would also reduce the force of gravity because time is part of the equation for acceleration. I know this may only be...

    Does gravity affect gravity the way gravity affects time?

    Since time is part of the equation for acceleration, and time slows as gravity increases, would this not limit the amount of gravity a black hole could produce? It seems that this would be a kind of negative feedback that would prevent the formation of a black hole out of an accretion disk...

    Uncovering the Mystery of Constant Velocity

    My understanding is that the speed of light is the same everywhere and has been the same since the beginning. There is some speculation that the speed of light may have been different in the past but no observational evidence exists.

    How Do Voltage and Current Interact in an Electrical Circuit?

    Hi swraman, you beat me to it:smile: Nice post. I can vouch for your comments.

    How Do Voltage and Current Interact in an Electrical Circuit?

    Let me give it a try. Electrons move from atom to atom, migrating from a more negative toward a more positive potential. You can think of it is the electrons moving from a place where there are more electrons to a place where there are less. You can think of voltage and current as pressure...

    Is colour dependent on wavelength of frequency?

    Yes; you have understood the postings the same as I have understand them. So, surely you are correct. :smile:

    Exploring Heisenberg Uncertainty Principle

    Yes; I understand all of that. Agreed. We were thinking in terms of the single photon that is emitted when an electron in one atom changes energy levels. I guess it is just not useful to think in those terms.

    Exploring Heisenberg Uncertainty Principle

    Ok; thanks; I think I'm getting the picture; I'll dig through the lit some more.
