    Learning Relativity: Is Speed of Time Relative to Observer's Spatial Movement?

    Hi Cam875. I think what you need to get your head around is that with respect to you The with respect to you part is important, because somebody who is standing still will also measure the lights speed as being c. The reason for this is that velocities don't just add up the way they seem to.

    Graininess of Space-Time found at GEO600?

    This is incredible! I've always believed space-time was composed of discrete points, but to actually be revealed in experiment is truly remarkable!

    Is There a Paradox in Amelino-Camelia's Doubly Special Relativity?

    I'm not sure I agree. I quote this from wikipedia I could be wrong here, but in my understanding a difference between SR and DSR is that in SR an objects length (in the direction of travel) tends towards 0 as v tends towards c. In DSR, an objects length (in the direction of travel)...

    Is There a Paradox in Amelino-Camelia's Doubly Special Relativity?

    Is there not an inherent paradox in Amelino-Camelia’s DSR (Doubly special relativity)? Every solid piece of matter is the sum of its parts. Put another way, all the building blocks of a meter stick must be less than a meter in length (e.g. the lines dividing centimeters, millimeters, the...

    Why can we shield some forces but not others?

    Also... as Arthur C. Clarke puts it. Cavorite, or anything that could nullify a gravitational force would allow for the creation of free energy, or put another way, a perpetual motion machine.

    Why did slide rules not have the ability to do simple addition and subtraction?

    Thanks a lot... that sounds a lot more feasible.

    Why did slide rules not have the ability to do simple addition and subtraction?

    Heres something interesting I noticed the other day. I had just made a cup of coffee in a ceramic mug, and had just finished stirring it. Absent mindedly, I started picking up my spoon and dropping it into the cup at roughly half second intervals. On doing this, I noticed something very...

    Jumping over objects while in motion

    I assume youre looking at the object that's jumping from side on right? (Like a Platformer) I also assume that you must be keeping its x, y velocities independent from each other. y | | | |________ x If that's the case, keep your x-velocity constant as the jump is made. To start...

    Truck and Car Collision at 70mph: Effects of Acceleration on a Moving Trailer

    :biggrin: Depends if its front wheel, or back wheel drive

    Could someone me get my mind around this paradox

    Okay... I am pretty sure this isn't a paradox, so my reasoning must be flawed somewhere. Could someone tell me where I am going wrong? Consider 2 electrons, traveling in straight lines, parallel to each other, at the same speed v, in the same direction. An observer in a stationary...
