I am puzzled by the concept that a bound electron, when changing state and emitting a photon, takes no time for the transition. The electron can...
Interesting discussion. Hehe, this is almost the question I wanted to ask, but since you're started it- Assuming the bullet is traveling very...
Thanks for the replies. So the bullet measures contracted length in the direction of travel AND in the opposite direction to its travel. Lets...
My relativistic rifle has a 1 meter long barrel and accelerates a bullet to (insert any near 'c' speed) relative to the rifle by the time it reaches...
Initially, your momentum would force you to continue traveling at a tangent to the surface in an easterly direction. The speed would not be enough to...
Brandon, the free falling observer is accelerating with respect to some frames (in this instance, its the BH) but its rest frame is inertial because...
Do you? In GR a free falling observer is inertial. A stationary observer in curved spacetime is accelerating (eg/ standing on the earths surface...
Thats one conclusion, not necessarily the only or correct one. I'm an inertial observer, therefore my observation is equally valid.
Hmmm. Lets not get too hasty here. Consider this scenario. Two stars are both in free fall in the same straight line trajectory towards a distant...
Janus58 is correct, but there is a purely practical consideration to take into account when measuring extremely short time intervals by this method....
My original statement Response posted by ddovala No, you are incorrect. You are no doubt confusing the popular description of the reduced...
Photons always travel at c, irregardless of the refractive index or otherwise of the medium. Photons have no rest mass. Photons have no spatial...
Inertia is an instantaneous opposition to acceleration. The gravitational potential required for inertia (as per Mach) is not required to travel at...
Hi Lilicia Here's a simple way of looking at this issue. Consider that light is the fastest speed possible for us or any other mass. We cannot...
Not really. It would indeed rely on the momentum of photons, but I'm suggesting that a massive body in our universe, that is 'out of step' with the...
Just a thought regarding photons and the momentum carried by these quanta. That is, p=hf/c. If I travel toward a light source, I will see the light...
Sorry, I don't share your views on photons. I had an excellent reference site for you to read, but they've disappeared :) I suggest some reference...
OK, the relevant part of your response is that you regard a single photon as being a wave. It has an amplitude that is seen to vary with time and it...
