    B Is there a way to measure gravity in a particular area of space

    How would one calculate the trajectory of a photon around a planet/star?

    B Is there a way to measure gravity in a particular area of space

    Why can't an object's gravity be measured without comparing it to another object (edited)? It's a physical property that exists in space, no?

    B Is there a way to measure gravity in a particular area of space

    Dumb question probably -- But is there a way to measure gravity in a particular area of space, or a "measurement" .. I.E. the gravity 10 miles above earth v.s 1000 miles above. Not force on another object, but some "unit" or measure of gravity itself.

    Is the speed of light infinite?

    The reference point could be the center of the 'space'.

    Is the speed of light infinite?

    If there was a 'space' or universe with just one electron. What would prevent the electron from traveling from one side to the other faster than c?

    News Troubling Coverage of the Fort Hood Shootings

    Who cares what the motive was? If there were "politics" involved with the media coverage (to avoid muslim hate crimes) , why is this troubling to you?

    Are there any good viruses for human beings?

    Cool. I wonder if any other components to the human body evolved from a virus or bacteria? White blood cells maybe?

    Are there any good viruses for human beings?

    I've wondered about this myself.. Going by evolution logic, wouldn't it make more sense if a virus actually was beneficial to the body it lives in? That way the virus could be easily spread to other hosts over a longer period (since it would make the host live longer on average)...

    This is funny because this is exactly how illogical people think... This must really appeal to all the Glenn Beck fanatics..

    A few questions on time

    Well, how about with gravitational time dilation effects instead of velocity? If you could feel the gravity of 100 suns (and the "time" in that frame), would this be considered relative as well?

    A few questions on time

    Right, I guess that's why someone mentioned this is more of philosophy discussion... How could you measure a personal experience traveling at .9999c?

    A few questions on time

    Heh.. No, but I could argue that there's nothing to compare the feeling of my frames "time dilation" to.... We've all pretty much evolved in it.

    A few questions on time

    Again, I'm talking about human time perception, and this probably isn't the appropriate place to discuss it unless SR talks about it specifically.

    A few questions on time

    I have no idea... Maybe their movement would seem restricted? I was also curious if the travelers size would increase with velocity relative to the observer, and if that could change their perception of time as well.

    A few questions on time

    How is it known the observers (or travelers) mental perception of time is "in sync" with all other time dilation effects?

    A few questions on time

    I'm not questioning SR time dilation, though.

    A few questions on time

    A few questions on time

    Hello, If a human could travel at .9999c would their perception of time (in their own frame) be the same as the perception of time of a stationary observer (in their frame)?

    What is voltage?

    Ok, how about ... Voltage is the measurement of (potential) work done per coulomb of charge... which is caused by the electrostatic force.
  24. N

    What is voltage?

    This may be incorrect.. But couldn't voltage just be considered a measurement of electrochemical attraction (electrostatic force) between ions? In a 12V battery you have "holes" or positive ions on one side, and "extra" extra electrons on the negative side... Once a conductive path is...

    Charge - what is it?

    Why can't you just say it's a quantity of electrostatic force (either + or -). edit: This might be a 'deeper', more meaningful definition.

    Gibbs energy of formation and electrolysis efficiency

    Hello - I'm having some problems understanding Gibbs energy of formation, and how it's applied to electrolysis. So, I'm hoping someone can explain what I'm doing wrong.. According to his site: http://hyperphysics.phy-astr.gsu.edu/Hbase/thermo/electrol.html (image) The change in the Gibbs...

    Does space resist the passage of light?

    I doubt the above equation has any equation has meaning, either, and if it did... A lot more information would be required to show that it does.. I don't even think "impedance of free space" is a (known) real property of free space (?) But, I think saying "the speed of light in free...

    Vibrating molecules?

    Ok, so here's my understanding now. Molecules just have an intrinsic vibrational energy that can be considered stored energy.. This energy can't be utilized, and is just "there"... It has no special name. Then there is a bond energy "vibrational", (seperate from above) that is a...
