I don't think that's true. If you dive head first your head will be 6 feet lower than your feet, and will be experiencing a different pressure than your feet. But a cross section of your body where every point is the same depth would have the same pressure (is that what you mean?). So really...
i think I am getting tripped up by relative simultaneity, which I do not fully grasp. It still seems intuitive to me that things happen absolutely regardless of your frame of reference, and your frame of reference should only change the way you perceive the events happening. Even though from...
because in either scenario maximum velocity is achieved instantaneously. and once they are traveling at a constant velocity I don't understand how one is different from the other.
For example a 3rd separate scenario. clock B is already traveling near light speed. it passes earth, and as it...
separate. it was initially one up until this paragraph:
"Now what if twin B just sits in his spaceship and doesn't accelerate. The Earth and the other planet 1 light year from Earth instantly accelerate to light speed (all movement of Earth is mirrored exactly by the other planet) and...
can you clarify which scenario you are referring to? My first scenario is B jetting off, then returning. A second completely separate scenario is A along with the Earth moving away from a stationary B, then returning.
scenario 1 = A never accelerates in any direction. B...
but in the 2nd paragraph B is in an inertial frame. He never moves or accelerates. The Earth and other planet do the accelerating and traveling. So from his point of view twin A races some distance away, then returns. Now say B sees 2 years pass as he sits in his spaceship just waiting for...
I didn't know what effect, if any, acceleration would have.
Now say clock A has a synchronized counterpart clock A' that's located on the other planet. Am I correct to assume that A and A' will always be synchronized because they are experiencing the exact same gravitational force, and are...
So if I define each starting point as "1", the first pass on Earth as point "2", and the point B passes the 2nd planet as "3"...
between points 2 and 3 one year will have elapsed on A's clock. less than one year will have elapsed on B's clock.
What about between points 1 and 2? Only a...
Also I am making an assumption that twin B is traveling so close to light speed I am just assuming he is at light speed (even though its technically less). So I know the planet is 1 light year away, and even though I don't observe twin B actually passing the planet at my 1 year mark, I know it...
I've been wracking my brain for days trying to comprehend everything that deals with the twin paradox. I have a vague understanding of relativity and its effects, but am massively confused by most of the explanations given on this forum and other places. I think perhaps it extends from my lack...
