oops i yeah , i had that misconception for long. even with using the average speed of the trip mentioned above. the question popped in my head when i knew that GPS satellite are calibrated for less gravity due to the altitude although the experience zero gravity

As you see, there's no difference in whether you are moving with constant velocity wrt. the reference frame or whether you are accelerated. The proper time ##\tau## is always given by this integral, and ##\tau \leq (t_2-t_1)## in any case, i.e., the moving observer always ages less compared to...

There's a common example to explain time dilation that states ... "if you traveled at a speed close to the speed of light and came back in a round trip of 1 hour , you may find that on the departure frame of reference 2 hours had passed" but that 2 hours trip can't be done without accelerating...

let's take inputs to the extreme, say the pressure meter is just an inch under the trough hight, and in opposite extreme , presume it's 3km deep. I think it's obvious that whatever going on the water surface won't affect the readings at that depth. So, in your example , there will be fluctuation...

I'm curious to what defines a thread to be closed "for moderation" ?? Is the title bad? Lots of spilling errors or bad grammar? Do I claim something like the Earth being flat ? Or is it wrong to interpret things with different ways?

consider the beam is 2 beams with half length attached together , and each has its own cog ...cog 1 above water and cog 2 under water, now the lower beam fully submerged and have a buoyancy force acting almost exactly at the same point of cog 2 upward with 0.5 , and the upper beam have have a...

that what i did from the start, thinking about all components, actions and reactions across time , and that lead me to a result that was refuted by almost everyone through analysis that i can't quite comprehend. weird results don't stop me. nothing is weirder than space stretch, time dilation...

as in general or that's related to my proposed experiment ?

i think I'm starting to get it , I'm thankful for all the support and time :)

Gravity is not a part of the system , since the whole system is subjected to it. nothing in the system pushes the water down. i guess the term "particle" was not accurate or misleading , what i meant is , for every amount of water that accelerate falling by gravity, there's equal amount that...

i admit , the mass center change concept sounds compelling , I'm on it but i can't go further with it before sorting out couple of issues : 1- There's no component in the system that exert power on the mass center forcing it into action , so how can we expect a reaction (loss of reading on...

thank you for the videos , they are so cool. i'll focus on the issue of center of mass shifting as mr. haruspex also suggested that.

true, but in the box, if you let the mass in, hanging by your hand, the reading won't change, unlike the original

the reading will drop for specific period of time then it will increase much more for a much less period of time . but this case include the weight hanged is directly affecting the scale through the box walls and the existence of the weigh inside the box has no secondary effect such as that of...

now this really made my day. I'm glad i get another confirmation. and as for looking at the mass center. well, i see the empty half of the glass and you see the filled half, it's same result :) . physics is very tricky and i fooled my self many times unintentionally by dropping an element or...
