I honestly don't understand what you think I'm doing that involves differentiation. If you're referring to the expectation value of v, even though the magnitude of v is constant, v itself is being treated as an operator in this case, so it is not a constant. Yes, it is certainly is mainstream...

@starthaus: For any given velocity, at that velocity y is constant (as I made sure to mention in my post), so it is being treated as such. Also, y is not dependent on the operator v, but on the magnitude squared of v, which is a number. Furthermore, what does differentiation have to do with an...

Hello everyone. First of all I'd like to thank those of you who are actually paying me the courtesy of having a dialogue with me and trying to help me understand the standard rebuttals to the arguments I'm presenting instead of simply dismissing me and calling me wrong with little or no...

Are you seriously suggesting that Special Relativity is absolutely correct and complete because it hasn't been disproven yet? SR has only existed for 100 years. Newton's conception of absolute space and time existed for over 200 years before Einstein altered it, and Newtonian physics conquered...

A very good point. However, you are still neglecting the fact that because the ship is accelerating, the fuel mass is being dilated. Because the usable energy of the fuel is some fraction of E = m0c2, and the resulting photons have energy E = hv (where v is the frequency, we have that (for the...

The significance is that even though c is finite, light will always be measured to travel at c regardless of your velocity, or inertial reference frame (IRF). A physical property that remains constant in all IRFs is a pretty big deal in a theory concerning the physics of different IRFs.

Actually time dilation is the only way that my scenario can make sense. It is the fact that time dilation cancels out with mass dilation which makes the efficiency of the rocket constant in any reference frame. The efficiency of the engine mentioned in this thought experiment is not based on...

I know the work would go to infinity. I was simply playing Devil's Advocate to generate some dialogue, not looking for a link. My point is that though the work would appear to go to infinity, so would the mass of fuel in my spaceship because of m=ym0. Since my engine (and any engine really)...

There are several problems with this. First of all, whose reference frame are you talking about here? Is 'v' the velocity measured by the stationary observer? If so where did the gamma factor come from? Are you saying that the velocity of the spaceship will be observed to be v = gamma*v? Second...

Why not? In my own reference frame I have just broken the light barrier, something that is supposed to be impossible. According to Einstein, all reference frames are equally valid, so I have definitely just gone faster than the speed of light in some way. Are you telling me that at the very...

These are a more general form of the same equations posted before, which still define acceleration in a way differently than I have. In this set of equations acceleration is being measured by a distant observer which can then not be used in conjunction with the proper time of the traveller, as...

Hi Cleonis, thanks for your response. I couldn't agree more about the serious lack of fruit present when it comes to using instantaneous comoving frames in relativistic acceleration, which is where my whole problem with this problem lies. According to the link that was previously put in this...

Actually rapidity is arctanh(v/c), which is still limited to velocities below c. The extrapolated velocity is not a real velocity in any reference frame because in this situation we are accelerating, so there is no inertial reference frame. This quantity represents an assumed velocity that one...

From the point of view of a photon (or any other massless particle for that matter), light does leave a source and arrive at its destination instantaneously. This is because for things traveling at the speed of light (thus only massless objects) the line element for measuring distances becomes...

This explanation is still based on the perspective of a distant observer, stationary with respect to the spaceship. As I stated before, from his point of view the rocket would indeed constantly become more massive as it's velocity approached c, and would thus need a constantly increasing energy...
